Lexus GS 350, 2010

Lexus GS 350, 2010

 

The 2010 Lexus GS 350 and Lexus GS 460 deliver a unique combination of luxury and sport performance to the Lexus vehicle lineup. Several technology enhancements continue to keep GS models at the top of their segment for 2010.

New exterior colors are offered to complement the advanced technology added to the 2010 GS 350 and GS 460. Deep Sea Mica replaces Black Sapphire Pearl and Satin Cashmere Metallic replaces Golden Almond Metallic. In addition, Parchment leather interior takes the place of Cashmere.

Engine/Transmission/Drivetrain/Performance
The GS gas luxury sport sedan comes in three models - GS 350 RWD, GS 350 AWD and GS 460 RWD. Optimized for low internal friction, the GS 350's 3.5-liter V6 engine produces 303 horsepower at 6,200 rpm and 274 lb.-ft. of peak torque at 3,600 rpm. A direct fuel-injection system provides much finer fuel-mixture control to improve both power and fuel efficiency. Dual Variable Valve Timing with intelligence (VVT-i) acts on both intake and exhaust valves to further enhance performance through a wide rpm range. A smooth-shifting six-speed transmission allows sequential shifting when desired.

The Lexus GS 460's V8 produces 342 horsepower at 6,400 rpm and 339 lb.-ft. of peak torque at 4,100 rpm. The GS 460, like the Lexus GS 350, meets the EPA's Ultra Low Emission Vehicle (ULEV-II) certification. Lexus has been setting standards for powertrain smoothness since its inception, and the GS 460's V8 and eight-speed automatic transmission continue that tradition. The transmission, like the six-speed automatic in the Lexus GS 350 models, allows manual shifting for a more engaging driving experience, and helps to maximize performance in certain driving situations. The Lexus GS 460 can accelerate from zero to 60 mph in 5.4 seconds, the Lexus GS 350 in 5.7 (5.8 for AWD).

Chassis/Body/Suspension/Tires/Brakes
The Lexus GS combines proven chassis systems with advanced dynamic handling technology to provide both agile handling and the Lexus trademark smooth ride. The double-wishbone front suspension and multilink rear suspension virtually eliminate unwanted wheel-angle changes during suspension movement. The result is a natural, confident feel that's also spirited. A 34.1-ft. turning circle (35.4 ft. for GS 350 AWD) is comparable to that of smaller cars and helps make the GS highly maneuverable.

In all GS models, Brake Assist (BA), Electronic Brake-force Distribution (EBD) and the Anti-lock Braking System (ABS) help form a powerful safety front. EBD optimizes brake pressure at each wheel to help reduce body dive or sway during hard braking and cornering. BA is designed to determine if the driver is attempting emergency braking, and, if the driver has not stepped firmly enough on the brake pedal to activate the ABS, it will apply increased braking force until pedal pressure is released.

Aluminum-alloy 18-inch wheels are standard on the Lexus GS 460 and available for the rear-wheel-drive Lexus GS 350, which features standard 17-inch wheels. For maximum handling capability, the Lexus GS 350 comes standard with 225/50R17 W-rated summer tires. The all-season 17-inch run-flat tires that are standard on the Lexus GS 350 AWD model are available on the GS 350 RWD. The GS 460 is equipped with 245/40R18 Z-rated summer tires or available all-season run-flats.

The Lexus GS 350's available all-wheel-drive system helps to enhance handling in diverse driving conditions. A planetary-gear center differential and a wet-type multi-disc clutch control front-to-rear power distribution. The system normally sends 70 percent of available power to the rear wheels to provide the traditional performance advantages of a rear-drive car and will vary the torque-split ratio from 30:70 to 50:50 in response to driving conditions and driver input. The AWD system's electronic-control strategy takes inputs such as steering and throttle angle from driver activity combined with vehicle signals from wheel speed and yaw rate sensors.

Lexus ES 350, 2010

Lexus ES 350, 2010

 
The Lexus ES 350 debuts revised styling, new luxury amenities and the all-new telematics system, Lexus Enform™ and Safety Connect™, for 2010. Newly standard rear seat-mounted side airbags bring the number of airbags in the Lexus ES 350 to 10.

In its fifth generation, the Lexus ES 350 continues to blur the line between "entry luxury" and "prestige luxury." Revised headlamps, a new grille, new grille surround, chrome body side molding and new front bumper with revised lower intake and integrated fog lamps underscore the car's refined character. Side mirrors now feature integrated turn signals, and the tail lamps are redesigned. Elegant new exterior colors accentuate the distinctive design in the 2010 ES 350.

For 2010, renowned Lexus luxury is enhanced by revised steering wheel controls, as well as new wood trim choices. A revised center console offers more storage than before. An array of new user technologies expands navigation capability and music playing options. The updated optional navigation system features improved Voice Command casual-language voice recognition to enhance owner convenience.

The new standard Lexus Memory System controls and stores settings for the driver's seat (except lumbar), outside mirrors and steering wheel. Rain-sensing windshield wipers, previously optional, are now standard.

Two all-new telematics products are available with a complimentary one-year trial subscription. Safety Connect is standard on non-navigation equipped vehicles. Lexus Enform, which automatically comes with Safety Connect, is only available with navigation-equipped vehicles.

Engine/Transmission/Drivetrain/Performance
The Lexus ES 350's aluminum 3.5-liter V6 produces 272 horsepower at 6,200 rpm and 254 lb.-ft. peak torque at 4,700 rpm. The chain-driven camshafts employ Dual Variable Valve Timing with intelligence (Dual VVT-i) for optimal performance and efficiency at all engine speeds.

The six-speed automatic Electronically Controlled Transmission with intelligence (ECT-i) provides a sequential manual shift feature for a more involved driving experience when desired. Shifting strategy adapts to driver input, with rapid kick-down response.

Chassis/Body/Suspension/Tires/Brakes
The Lexus ES 350 owes its smooth, quiet ride in large part to a rigid unibody structure that allows the four-wheel independent suspension to be tuned to provide responsive handling agility and ultra-smooth ride quality. The low 0.28 coefficient of drag (Cd) helps minimize wind noise while also helping to maximize highway fuel efficiency. Standard 17 x 7-inch aluminum alloy wheels with a new split five-spoke design carry 215/55R17 all-season tires. A full-size spare wheel/tire is available.

Standard Vehicle Stability Control (VSC) with traction control system integrates the Anti-lock Braking System (ABS), Electronic Brake-force Distribution (EBD) and the Brake Assist (BA) safety feature. A new VSC cut-off switch for 2010 is useful if it becomes necessary to extricate the car from deep snow or other difficult conditions, such as mud or sand.

Safety/Security Features
A reinforced front- and rear-structure passenger compartment forms the foundation for passive safety in the Lexus ES 350. In addition to advanced dual-stage front airbags and front seat-mounted side airbags, the Lexus Supplemental Restraint System includes rear seat-mounted side air bags (previously optional, now standard), side-curtain airbags that extend from the A-pillar to C-pillar and a knee airbag for both the driver and front passenger, for a total of 10 airbags throughout the cabin.

The optional Pre-Collision System (PCS) can help reduce collision damage. The package includes Dynamic Radar Cruise Control, which uses millimeter-wave radar to measure and help maintain a pre-set distance from a vehicle traveling ahead. The multi-information display within the combination meter will show a car icon with the selected following distance.

The optional dual-swivel Lexus Adaptive Front Lighting System (AFS) helps illuminate a turn or curve as the driver steers into it. A medium-to-high speed mode (over 19 mph) allows both the right and left front headlamp bulbs to swivel toward the direction of the turn at the same time.

Land Rover Range Rover, 2010

Land Rover Range Rover, 2010





The 2010 Land Rover Range Rover has two brand new 5.0-liter LR-V8 engines - the top of the range 510 bhp supercharged unit, and the 375 bhp naturally aspirated version. Both engines were developed in-house by the Jaguar Land Rover powertrain team, with the requirements of the Land Rover Range Rover in mind from day one.

The LR-V8 engines have been developed to deliver more power and refinement but without a corresponding increase in consumption and emissions. The result is a pair of lightweight direct fuel injection engines with class-leading efficiency, which provide significantly more usable low end torque and superior dynamic responses without compromising power at higher RPM. Both engines are compliant with stringent U.S. ULEV2 emissions regulations.

The performance of the all-new naturally aspirated LR-V8 is now a virtual-match for the outgoing 4.2L supercharged engine. The new naturally aspirated vehicle completes the 0-60 mph sprint in 7.2 seconds (just 0.1 seconds off the pace of the outgoing supercharged unit). For those who want the ultimate performance Land Rover Range Rover, there is now the all-new LR-V8 5.0L Supercharged, which is propelled from rest to 60 mph in an impressive 5.9 seconds.

Direct injection - increased power and torque, lower emissions
One of the key features of the new LR-V8 is an industry first, centrally-mounted, multi-hole, spray-guided fuel injection system, delivering fuel at a pressure of up to 150bar (2,175 psi) directly to the cylinder. The positioning of the injectors ensures fuel is precisely delivered to the center of the combustion chamber, maximizing air-fuel mixing, and improving combustion control.

Fuel is delivered by twin, high pressure fuel pumps driven via an auxiliary shaft in the all new engine block. Delivery of fuel direct to the cylinder has substantially contributed to improved low speed, dynamic response which is particularly useful off-road while adding to driving pleasure on-road. The charge cooling effects of the direct injection fuel system have allowed the compression ratio of the naturally aspirated engine to be raised to 11.5:1, further improving the engine efficiency.

During the engine warm-up phase, the combustion system employs multiple injection mode strategies to deliver 50 percent more heat for fast catalyst warm-up and reduced emissions.

6th generation Eaton™ supercharger - quieter and more efficient.
A sixth generation, Eaton™ twin vortex system (TVS) supercharger is fitted to the 510 bhp engine. A compact Roots-type unit, it feeds air through twin intercoolers which in turn are water-cooled by their own cooling circuit. The high helix rotor design both improves the supercharger thermodynamic efficiency and improves noise quality to the point where the unit is virtually inaudible. The intercoolers reduce the temperature of the pressurized intake-air and so optimize power.

The air intake has been radically redesigned compared to the previous V8. The intake air path is a direct feed to the supercharger inlet from the centrally mounted front throttle body. Air is delivered through twin air boxes which reduce flow loss and further increase efficiency. Mechanically, the new supercharger and its intercoolers are efficiently packaged in the V of the engine to deliver a low overall engine height.

New variable camshaft timing system boosts engine torque, saves energy
A new type of variable camshaft timing system (VCT) on the V8 engine introduces another industry first. The four VCT units are activated by the positive and negative torques generated by opening and closing the intake and exhaust valves, instead of by oil pressure. This has allowed the engine oil pump to be reduced in size, saving energy and reducing fuel consumption.

VCT units work independently on all four camshafts with 62 degrees of authority on the inlet cams and 50 degrees of authority on the exhaust cams. Timing is optimized by the engine control unit for torque, power and efficiency at every point in the engine's speed range.

The response rate of the new VCT units is 25 percent quicker than before with actuation rates in excess of 250 degrees per second. This delivers a more immediate engine response to the driver's demand.

Camshaft profile switching - flexibility with performance
In addition to VCT, the naturally aspirated LR-V8 is also equipped with camshaft profile switching (CPS) on the inlet camshaft. Depending on the engine's running conditions and the requirements of the driver, the CPS will switch between a profile that is ideal for low speed driving, and another which gives increased valve lift for high performance. This feature helps endow the Land Rover Range Rover with ample low end torque in demanding terrain, yet fully exploits the potential of the 5.0-liter V8 when conditions allow.

An hydraulically-actuated two-piece tappet switches between profiles on the tri-lobe camshaft altering both the lift and duration. The cam lobe profile selected for engine speeds below 3000 rpm has a duration of 214 degrees and lifts the valves 5.5mm. This optimizes gas velocity for improved low-speed torque and reduces valve train friction for improved fuel efficiency. For high-speed driving, CPS switches to a cam lobe with a duration of 250 degrees and valve-lift of 10.5mm, allowing greater air flow into the engine for high power.

Land Rover Freelander 2 Sport, 2010

Land Rover Freelander 2 Sport, 2010




A unique two-tone interior is introduced on both derivatives, in contrasting Ebony and Storm. The derivative featuring the sports styling pack will offer a leather interior and the standard version with a cloth/leather interior.
The Sport emblem is embossed on the front and outer rear seat head restraints, with Storm coloured stitching on all seats and unique Ebony interior carpet mats with contrast piping feature throughout.

The Land Rover Freelander 2 Sport is available with the powerful and economical 2.2-litre TD4 diesel power unit. The manual diesel comes with Stop/Start technology delivering an 8% improvement on CO2 emissions compared to the previous manual diesel Land Rover Freelander 2 (from 194g/km to 179g/km) and fuel consumption is reduced (from 37.7 to 42.2mpg - an improvement of 4.5mpg).

Land Rover Discovery 4, 2010

Land Rover Discovery 4, 2010




The new, fourth generation of Land Rover's supremely versatile seven-seat vehicle gains a new name - Land Rover Discovery 4 - to go with its powerful and highly efficient new TDV6 diesel engine, fresh exterior identity and more premium cabin. The class-leading breadth of capability is extended even further with dynamic improvements for both road and off-road driving, and Land Rover has added a battery of user-friendly new technologies and features.

Star billing on the Land Rover Discovery 4 goes to the highly efficient and refined new LR-TDV6 3.0 twin turbo diesel engine. This delivers a 9 percent fuel economy improvement (EU combined cycle) and ten percent less CO2 emissions, at the same time as increasing power by 29%, all compared with the existing 2.7-litre engine. Torque increases even more, up 36% to 600Nm - believed to be the highest torque output of any 6-cylinder, production diesel, passenger vehicle engine in the world.

The power and torque are both accessible across the entire rev range, to deliver immediate throttle response and effortless cruising ability. The results include a 0-60mph time of 9.0 seconds, (0-100 km/h in 9.6 seconds), a 24 percent improvement over the 2.7-litre.

The iconic exterior design has been updated, most obviously with smoother and simpler surfaces at the front, including a new, more aerodynamic bumper. The sportier new lights help give the vehicle new character, and include LED technology front and rear. The sophisticated new front headlights include High Beam Assist, switching on or off, as conditions require.

The interior is completely redesigned, with a transformed dash and centre console, new seats and an array of new, user friendly features.

e-Terrain technologies boost economy and lower CO2 emissions
The new Discovery is packed with features aimed at reducing fuel consumption and reducing CO2 emissions. The new LR-TDV6 3.0 Sequential Turbo Diesel engine was designed from the outset to deliver class-leading fuel economy and improved low-end torque.

The parallel sequential turbocharging system of the 3.0-litre diesel makes use of its larger, primary turbo most of the time. The smaller secondary turbo remains dormant when higher power is not required, reducing pumping losses and consequently, fuel consumption. A highly efficient, third generation common rail injection system with piezo injectors and fuel metering, also makes a substantial contribution to fuel economy.

The new engine has been also been optimised for low-end torque as well as economy, making it possible to activate the lock-up clutch of the ZF HP-28 automatic transmission at lower speed. This reduces 'slip' in the hydraulic torque converter improving both fuel consumption and CO2 emissions. The higher torque at lower rpm also enables longer gearing for more economical cruising.

The Discovery incorporates several other energy saving features too. At standstill, the idle speed of the V6 has been reduced from 750rpm to 710rpm, giving a fuel saving without compromising refinement. An Intelligent Power Management System includes Smart Regenerative Charging, so whenever possible the alternator charges the battery when it is most economical to do so, such as when the car is coasting rather than accelerating.

Aerodynamic changes to the front end, with the revised front lower chin spoiler and new front wheel deflectors, help to reduce drag by increasing underfloor airflow.

The new air conditioning pump is driven through a clutch which disengages when the air conditioning is not in use reducing parasitic losses and delivering improvements in fuel consumption and CO2 emissions.

At the heart of the improvements introduced with Land Rover Discovery 4 is an exceptional and highly efficient new diesel engine. The LR-TDV6 3.0 sequential turbodiesel is based on the existing LR-TDV6 2.7-litre engine, but radically redesigned to deliver substantially higher performance, lower emissions and better fuel economy.

The 2.7-litre has won many admirers as one of the most refined diesels ever made. The new, twin turbocharger LR-TDV6 3.0 boasts substantial increases in both power - up 29 percent to 245PS - and torque, up 36 percent to 600Nm. The ability to deliver maximum torque at just 2,000rpm, combined with unparalleled throttle response, substantially enhances the Discovery's already acclaimed ability both on and off-road.

The new 3.0-litre diesel can significantly out perform its rivals by delivering 500Nm in only 500 milliseconds from idle. From the driver's perspective this means instantaneous access to 83 percent of maximum torque.

But despite this extra performance, engine emissions are dramatically reduced. When fitted with DPF, the new LR-TDV6 3.0 meets EU5 emissions requirements (not due to come into force until 2011) and with a CO2 figure of 244g/km, it undercuts the existing 2.7-litre automatic by ten percent. Fuel economy is also improved by 9 percent, delivering 30.4mpg (9.3 l/100km) on the EU Combined cycle.

The new 3.0-litre engine has been developed by a joint Jaguar Land Rover team, with base characteristics designed from the outset with the requirements of both brands in mind. High levels of torque and fast response from low revs perfectly suits both Jaguar and Land Rover DNA. The Jaguar version, the AJ-V6D Gen III S, was recently launched in the new Jaguar XF.

The LR-TDV6 engine has a deeper sump than its Jaguar sibling, to ensure the efficiency of the lubrication system is not compromised when venturing off-road. The oil scavenge system of the turbochargers has been enhanced for a similar reason, ensuring no oil collects in the turbochargers at extreme angles in off-road conditions.

For the Land Rover version, belt drives are waterproofed, as are the alternator, air conditioning compressor, power steering pump and starter motor. The engine is also tuned specifically to allow for the greater demands made on the Land Rover Discovery 4, particularly for towing and all-terrain driving.

Land Rover Freelander 2 TD4 e, 2009

Land Rover Freelander 2 TD4 e, 2009









The new Land Rover Freelander 2 TD4_e is Land Rover's most fuel-efficient vehicle to date. Featuring a new intelligent Stop/Start system, it is the first production vehicle to incorporate technologies from the company's programme of sustainable engineering initiatives, collectively named 'e_TERRAIN TECHNOLOGIES'.

On the standard EU4 cycle, the CO2 emissions of the Land Rover Freelander 2 TD4_e are reduced by 8 per cent, compared with the outgoing manual diesel Land Rover Freelander 2. Moreover, in additional tests, Land Rover engineers have measured fuel savings approaching 20 per cent in heavy urban traffic.

The 8 per cent improvement equates to a CO2 emissions reduction of 15 g/km compared with the standard Freelander 2 TD4 manual (from 194 g/km to 179 g/km). In terms of fuel efficiency, consumption is reduced from 7.5 l/100 km to 6.8 l/100 km, a saving of 0.7 litres of fuel every 100 km (62 miles).

These gains, coupled with the added benefits of the gearshift indicator light, software developments and efficiencies from low-rolling-resistance tyres, make the Land Rover Freelander 2 TD4_e the most fuel-efficient production Land Rover ever built.

Phil Popham, Land Rover's managing director, said: "The Stop/Start Freelander 2 is the first production vehicle to benefit from the massive £700 million investment in sustainable technologies by Jaguar and Land Rover. From mid-2009, the Stop/Start feature will be included as standard on all Land Rover Freelander 2 TD4 manual models, with no associated increase in list prices."

Land Rover's new Stop/Start system improves fuel efficiency in urban and stop-start driving. The vehicle automatically shuts down the engine in appropriate conditions, resulting in zero tailpipe emissions and saving fuel that would otherwise be used idling the engine when stationary. When the driver is ready to move off, the engine instantly re-starts.

Sophisticated controls ensure that the Stop/Start system does not compromise the needs of either the driver or the vehicle. For the engine to shut down, the vehicle must be stationary, the gearbox in neutral and the clutch pedal raised. To re-start, the driver simply depresses the clutch and the enhanced starter motor engages the engine, ready for when first gear is selected.

The Stop-Start system is automatically activated each time the ignition is turned on, although there is a switch on the fascia to disable the system, if the driver so desires.

Added fuel economy benefits
Along with the intelligent Stop/Start system, the Land Rover Freelander 2 TD4_e includes a series of additional enhancements that help to deliver fuel economy and CO2 benefits.

A new gearshift indicator light in the instrument pack advises the driver when to change gear if a higher gear will allow the vehicle to operate more fuel-efficiently. This is calculated by the Land Rover Freelander 2 TD4_e's fully mapped engine.
Software developments to the driveline systems on the Land Rover Freelander 2 TD4_e generate CO2 benefits without reducing Land Rover's renowned capability.

Land Rover engineers are also collaborating with tyre suppliers to drive improvements to fuel economy through reduced rolling losses. Tyre characteristics including rolling resistance are optimised for the entire range of available tyre sizes on Freelander 2 models.

Refined Stop/Start operation
Land Rover engineers have invested considerable effort in safeguarding levels of engine refinement. To reduce the engine shake associated with some diesel engines when stopping, the Land Rover Freelander 2 TD4_e features controlled throttle closing and ramps down fuel in a smooth fashion, while the alternator is also turned off during the shut-down procedure, reducing load on the engine. A software feature change and revised engine calibration further aid smooth shut-off, while engine shake on start-up is reduced by the Freelander 2's optimised engine-mounting strategy and inherent tuning.

Uncompromised durability
The increased frequency of stop-start cycles over the lifetime of the Land Rover Freelander 2 TD4_e will lead to increased use of the vehicle's affected components, so enhanced durability of these components was a priority for the Freelander 2's engineering team. They developed a new heavy-duty starter motor, a new ring gear, a new dual mass flywheel friction control plate and an absorption glass mat battery. These new features ensure that the Land Rover Freelander 2 TD4_e delivers characteristic Land Rover all-terrain performance and that the system's operation is always rapid and reliable.

Enhanced starter motor
The more frequent stop and start activity means that demands on the starter motor are forecast to increase up to threefold during the lifetime of the Land Rover Freelander 2 TD4_e. To accommodate the durability demands on the vehicle's 2 kW starter motor, a number of changes have been made.

The grease seals have been enhanced significantly and new hard-wearing copper contact material has been sourced and specified across the TD4_e range to enhance wear resistance within the starter solenoid.

New ring gear
An all-new ring gear is specified for all TD4_e models to cope with the increased frequency of starts. The ring gear is attached to the engine flywheel and comes into contact with the starter motor each time the engine is started. The new ring gear is manufactured from a harder grade of steel and contains over 25 per cent more carbon to improve durability.

Dual mass flywheel friction plate
Diesel-powered Freelanders with manual gearboxes have always featured a dual mass flywheel to ensure engine refinement at start, stop and low speeds. A new Polyetheretherketone friction control plate has been developed for the Land Rover Freelander TD4_e. This is able to withstand seven times the pressure of the outgoing plate, to ensure greater levels of refinement under even greater start and stop demands.

Absorption glass mat battery
New absorption glass mat technology has been developed, which offers deeper discharge and recharge characteristics and reduces battery deterioration under much heavier usage. Fine glassfibre matting has been introduced to sit pressurised between the new absorption glass mat battery plates. This aids the battery's longevity in two ways: by allowing the electrolyte to function normally under greater pressure and by providing mechanical support for the plates, reducing battery degradation.

Cadillac Aera Concept, 2010

Cadillac Aera Concept, 2010


 
 
 

The Cadillac Aera Concept won the 2010 Los Angeles Auto Show Design Challenge, tying with Smart and besting entries from seven other automakers including Mercedes-Benz, Honda, Nissan, Toyota and Maybach. GM Advanced Design has now won the honor more times than any other design team; this is its third victory since 2005.
The Cadillac Aera Concept is powered by compressed air via a highly efficient Pneumatic Drive System that has a 10,000-psi composite air storage tank with capacity for a 1,000-mile range. Flexible, pressurized air cells in the exterior skin, similar to material developed for the NASA Mars Rover airbags, enhance passive safety and interior comfort. The flexible polymer skin optimizes aerodynamics and functions as an ultra-lightweight alternative to conventional body panels and glass.

Cadillac Aera's body utilizes a 3D lattice, mono-formed frame that was designed to be similar to configurations found consistently in nature. The structure is formed from unique, alloy-utilizing, semi-solid freeform manufacturing, creating a naturally strong, extremely lightweight frame. All major body parts, including interior components, are essentially "grown" into a single part lattice structure.
The interior is crafted with an ultra-light recyclable polymer that allows for HVAC channels, fully adjustable seating, storage and comfort features all in one mono-form structure. Generous storage space accommodates luggage for two people.

The concept was conceived in GM's North Hollywood Advanced Design Studio by Frank Saucedo, director; Phil Tanioka, vehicle designer; Brent Wickham, concept strategist; Shawn Moghadam, layout designer and Timonen, the project manager. Earlier this week, GM commemorated 10 years of advanced design at the L.A. area studio.

The Design Challenge is part of the Design Los Angeles automobile designers' conference and has evolved into an integral element of the Los Angeles Auto Show. Design Los Angeles connects those working in the design industry with well-known automotive design industry leaders. Los Angeles is home to the world's largest concentration of manufacturer design studios, representing automakers from North America, Europe and Asia. It is also the home of Art Center College of Design, one of the world's foremost transportation design institutions where many of today's leading automotive designers began their careers.

Cadillac Presidential Limousine, 2009

Cadillac Presidential Limousine, 2009



As Americans celebrate the inauguration of a new president of the United States, another new Cadillac will grace Pennsylvania Avenue to lead the proceedings. President Barack Obama will ride in an all-new Cadillac Presidential Limousine, continuing a long tradition of Cadillac limousines that have served many U.S. presidents.

Inside and out, the Cadillac Presidential Limousine includes many of the brand's signature design elements. Assertive, modern and elegant, the front of the car includes the intricate, dual-textured grille made famous by Cadillac's most popular current models, the CTS sport sedan and Escalade. Vertical design elements, such as the car's front and rear lighting, mirror those used on production models.

For largely functional reasons, such as optimal outward visibility, the car is slightly more upright than its predecessor. However, this new Cadillac Cadillac Presidential Limousine occupies roughly the same overall footprint on the road as the previous model, with a similar size and proportion.

History - Cadillac and the U.S. Presidency
Cadillac has built limousines and special vehicles for U.S. presidents, diplomats, ambassadors and foreign dignitaries since the early 20th century, an iconic aspect of the brand that continues today.

Cadillac's central role began during World War I, when many Cadillac engines and cars were transferred to military and government service because of their superior durability and power. One of the first chief executives to use a Cadillac was President Wilson, who rode through the streets of Boston during a World War I victory parade in 1919. A lavish 1928 Cadillac town car was used in the Calvin Coolidge administration.

In 1938, two Cadillac convertibles, dubbed the "Queen Mary" and "Queen Elizabeth," were delivered to the U.S. government. Named after the great ocean liners of the time, the vehicles were 21.5 feet long, weighed 7,660 pounds and were equipped with a full ammunition arsenal, two-way radios and heavy-duty generators. Durable and reliable, the two "Queens" served Presidents Franklin D. Roosevelt, Harry S. Truman and Dwight D. Eisenhower.

President Eisenhower, known as a car buff, rode in one of the first Cadillac Eldorado models ever produced during his 1953 inaugural parade. The Eldorado represented a high point in automobile design history, as it had the first wraparound windshield, a feature quickly adopted on other new production models.

In 1956, the Queen Mary II and Queen Elizabeth II convertibles replaced the original series. The vehicles were slightly smaller, but like their predecessors, were fully armored and featured state-of-the art communications. Moreover, the vehicles were fitted with narrow rims inside the tire in case the tires were shot out. The Queen Mary II and Queen Elizabeth II served not only President Eisenhower, but also Presidents John F. Kennedy and Lyndon B. Johnson. Both vehicles were retired in 1968.

The Ronald W. Reagan administration was delivered a 1983 Cadillac Fleetwood limousine and a Cadillac Fleetwood Brougham - Presidential Series was delivered to the William J. Clinton administration in 1993. Unlike previous models that typically were Cadillac cars adapted and modified by independent limousine companies, the 1993 Presidential Brougham was designed, developed and manufactured totally within General Motors and Cadillac. This included an extensive set of security measures to maintain confidentiality, a process that continues today.

Currently, the 1983 Cadillac Fleetwood limousine resides at the Ronald W. Reagan Presidential Library and Museum in Simi Valley, Calif., while the 1993 Cadillac Fleetwood Brougham is at the Clinton Presidential Center in Little Rock, Ark.

Cadillac has produced two presidential limousines this decade that remain in service. The first was a Deville Presidential model delivered to President George W. Bush in 2001. In 2004, President Bush debuted a new DTS Presidential model. It was the first application of a new design that launched later that year for the production DTS full-size sedan.

Cadillac Escalade Hybrid, 2009

Cadillac Escalade Hybrid, 2009



 
Cadillac announced the world premiere of the Escalade Hybrid, the world's first fuel-saving hybrid applied to a large luxury SUV. Powered by an innovative, fuel-saving 2-Mode Hybrid system, Escalade Hybrid will deliver more than a 50-percent improvement in fuel economy in city driving - all while delivering the same distinctive style, segment-leading features and full-size capability that have made the Escalade an icon.

The Hybrid goes on sale in the US in the summer of 2008 and is the newest example of Escalade's technology leadership. The potential for sales of the Hybrid in Europe are currently being evaluated with a decision expected within six months.

Patented 2-Mode Hybrid technology
The Escalade's 2-Mode Hybrid system allows it to return exceptional fuel economy in both city and highway while delivering the capabilities of a true luxury SUV. In city driving, this advanced hybrid power system enables Escalade to launch and drive low speeds on electricity alone. As additional power is demanded, the system blends output from the battery and gas engine smoothly.

GM's patented 2-Mode Hybrid system consists of an advanced electrically variable transmission (EVT) and 300-volt nickel-metal hydride Energy Storage System (ESS). These systems work in concert with the standard 6.0L V-8 Gen IV gasoline engine with Active Fuel Management (AFM) and late-intake valve closing (LIVC) technology. AFM enables the V-8 engine to seamlessly shut off half of its cylinders when less power is needed, such as during highway cruising. This new hybrid system not only enables the Escalade Hybrid to drive low speeds on electricity alone, it also allows the 6.0L V-8 engine to operate in its more economical four-cylinder mode for longer periods.

Cadillac's smooth and quiet power:
Acoustic details specific to the Hybrid model ensure it delivers the superior luxury that has been an Escalade hallmark since its inception. The details:
    * A new exhaust system and resonator specially tuned for the 6.0L LIVC engine's Active Fuel Management operation. It ensures comfortable interior acoustics and a pleasant exhaust note during both V-4 and V-8 operation
    * An electrically driven, 300-volt air conditioning compressor reduces vibration and allows the HVAC system to cool the passenger compartment even when the gasoline engine is shut off. It includes the standard tri-zone climate system
    * An electrically driven, 42-volt variable-assist power steering reduces vibration and provides up to a 0.5-mpg fuel economy improvement by reducing parasitic losses common in belt-driven hydraulic systems
    * The Energy Storage System cooling system's internal fan is tuned to be quiet at low vehicle speeds, when the fan could more easily be heard by the occupants.

Escalade aesthetic
The Escalade Hybrid retains the qualities that have made it the leading large luxury SUV and a standard-bearer of Cadillac's overall product renaissance. It is instantly identifiable as a Cadillac and incorporates styling cues from the landmark Sixteen concept vehicle, including a detailed signature grille, front fender vent ports and layers of chrome accents.

The Escalade's warm and inviting interior features a premium layout. It is available in two colors, Ebony and Cashmere. Standard features include a distinctive instrument panel; gauges with white needles and blue light inlays with continuously lit, white-LED backlighting; Nuance leather-covered seats; leather-covered door trim and center console; and a power-assisted rear liftgate that opens and closes with the touch of a button.

Cadillac CTS-V, 2009

Cadillac CTS-V, 2009


 


As the new CTS sport sedan earns accolades and new owners, Cadillac takes the next leap forward by premiering the 2009 Cadillac CTS-V, the brand's ultimate expression of performance and luxury.

Sophisticated technical enhancements
The 2009 Cadillac CTS-V features the world's fastest-reacting suspension technology, Magnetic Ride Control (MRC). It uses shocks controlled by electro-magnets, rather than mechanical valves, greatly accelerating response time. Electronic sensors at all four wheels literally "read the road" every millisecond, making constant adjustments to damping to create virtually instantaneous and extremely precise control of body motions. This is of particular benefit for a high-performance sedan, helping to keep the car very composed during hard cornering, acceleration, braking and other dynamic maneuvers.
