Bentley Continental Supersports, 2010

 

 

The Bentley Continental Supersports is the fastest and most powerful Bentley ever. It is the extreme Bentley, a muscular two-seater that delivers supercar performance and a highly focused driving experience. The Bentley Continental Supersports is also the first Bentley capable of running on both petrol (gasoline) and biofuel, pioneering the use of FlexFuel technology in the luxury sector. This represents stage one of the company's commitment to make its complete model range compatible with renewable fuels by 2012. Available worldwide from autumn 2009, the Bentley Continental Supersports will be FlexFuel compatible in the majority of markets from launch with North American cars offering the capability by summer 2010, following regulatory approval.

The Bentley Continental Supersports began as an 'under the radar' project exploring the possibilities of weight reduction on the Bentley Continental GT but with more power and torque. A largely experimental process crystallised over a period of 24 months into an official new car programme, driven by the passion and enthusiasm of a small group of Bentley engineers and designers. The results are dramatic. With 630PS (621 bhp) and new 'Quickshift' transmission that halves shift times, the Bentley Continental Supersports sets new performance benchmarks for Bentley. It accelerates from 0-60 mph in 3.7 seconds (0-100 km/h in 3.9 seconds) with a top speed of 204 mph (329 km/h).

The supercar performance is complemented by an array of chassis enhancements including retuned steering and suspension, utilising lighter weight components, retuned dampers and anti-roll bars. Agility is further sharpened by the 40:60 rear-biased torque split for the all-wheel drive system, a wider rear track, bespoke lightweight 20-inch alloy wheels and a unique electronic stability programme. Carbon ceramic brakes are standard fitment, benefiting steering response, grip and ride comfort, while saving weight. Overall, the engineering team have achieved a weight reduction of 110 kg (243 lb) compared with the Bentley Continental GT Speed.

The evolution of the Bentley Continental Supersports' design is very much a case of 'form following function' with new purposeful sculptural forms signalling the engineering changes beneath the skin. For example, the increased power and torque of the W12 engine necessitated additional airflow to the twin turbocharger intercoolers and cooling system. Bentley's designers responded with a purposeful and dramatic style that features large vertical intake apertures and twin bonnet vents. Similarly, new flared rear wings that accommodate the 50 mm (2 inches) wider rear track are designed to emphasise the powerful stance of this ultra-high performance coupe. The resultant Supersports style combines the looks of the iconic Continental GT with a new and distinctive appearance that reflects its more extreme character.

The Bentley Continental Supersports is further distinguished from its Continental coupe stable mates by a unique dark-smoked steel finish to all exterior 'brightware', including front grilles, lamp bezels, window surrounds and wheels. A complex 'Physical Vapour Deposition' process is applied to all stainless steel components to give a lustrous and highly durable finish. A car industry first, this process is normally used as a coating on industrial tools, watches and even hip replacement joints.

Fully embracing the extreme spirit of the Supersports, Bentley's interior designers have created a unique ambience. The cockpit represents a dramatic reinterpretation of Bentley interior design in which carbon fibre and Alcantara not only convey a sporting and contemporary style but also reduce weight. The Bentley Continental Supersports is a strict two-seater featuring all-new lightweight sports seats with carbon fibre clamshell rear panels. In the rear compartment, the seats are replaced by a stowage deck with a carbon fibre luggage retaining beam. The new interior also provides a showcase for the skills of Bentley's craftsmen and women at the company's factory in Crewe, England. Signature premium grade leather and brightware are complemented by carbon fibre panels, replacing traditional wood veneers.

The Bentley Continental Supersports is capable of running on either petrol and E85 biofuel or any combination of the two. E85 biofuel can offer a reduction of up to 70 per cent in CO2 emissions on a 'well-to-wheel' basis. Well-to-wheel is a measurement of a fuel's net CO2 contribution to the atmosphere, not just tailpipe emissions. It is a way of quantifying how much CO2 a fuel emits from its growth or extraction (well) to its combustion or deployment (wheel). It includes refinement, distillation and transport of the fuel. The fuel supply system detects the blending ratio of the fuel in the tank and ensures that power and torque remain constant regardless of the ratio of petrol to biofuel. The result is seamless power delivery in the Bentley tradition.

The 'Supersports' name is inspired by the original two-seater 3-litre Supersports model introduced in 1925, itself an evolution of the 3-litre Speed. The lightweight, 85 bhp Supersports was the first production Bentley to reach 100 mph and was also renowned for the application of Le Mans-winning race technology.

Bentley Continental Flying Star, 2010

Bentley Continental Flying Star, 2010

 

Flying Star in 2010 - the Bentley challenge
The Bentley Continental GT range set innovative and high standards for a new generation of very sophisticated Grand Tourers. As such, this model triggered the imagination of automotive designers and coach builders elsewhere. The GTC convertible, featuring a very rigid platform, proved to be a fully congruent basis to Touring Superleggera's plans for the new Bentley Continental Flying Star.

The new project required the modification of a number of external dimensions starting from the car's A-pillar backwards: extended roof line, a wider section including the doors, new aluminium door skins and a new all-aluminium, electrically operated tailgate. It also includes a completely new rear compartment with two foldable rear seats and a variable loading space.

This long list of modifications and transformations had to be paired with, and to remain fully compatible to the basic car's technical layout and components. Given the sophistication of the basic car, a new challenge was laid out for Touring's craftsmen and engineers. The final result proves that special coach building can live on well into the 21st. century working with respect to the original manufacturers.

Touring Superleggera is particularly proud of the fact that the complete productive cycle of the special coach building process was realized in their workshop near Milano. Modern body engineering went hand in hand with traditional handicraft skills, maintaining the highest quality directives for the final product.

Project Engineering
The body engineering processes at Carrozzeria Touring are aimed at safeguarding key parameters for quality, safety and feasibility, within the perspectives of low-volume automotive production. The project went through 1:4 and 1:1 modelling, based on the CAD and CATIA data from the basic vehicle. This digital basis resulted in a milled 1:1 master model and a number of 1:1 moulds for the manufacturing of the new external skin, and for important new body components. The rear bodywork was reinforced with an integrated structure between the rear suspension domes, functioning both as roll bar, and as support for the new, extended roofline.

Design
'Variations on a theme' not rarely implicate a larger design challenge, than starting-off with a white sheet of paper. The basic mission was to create a body incorporating the essence of Touring elegance and harmony, while clearly recognizable as a Bentley. This task was challenging because a fully new volume had to be added to the GTC basis. The proportions were totally new, but the overall design had to be kept consistent. That is why only the section in front of the car's A-pillar, including the windshield has been maintained.

Viewed from the rear, the new tailgate dives between the wide rear wings. The oval rear light chrome bezels are a reference to Bentley fastback cars of the '50. The side view features a low roof, prominent quarter panel shoulders and wide wheel arches, suggesting perfectly mastered energy.

The Touring Superleggera designers were challenged by the target to give the new interior equal elegance, whether the back of the rear seats are folded or not. The solution was to design an "S" shaped trim of the rear quarter panels linking the passenger area to the rear luggage area. The beige and dark green leather contrast also adds to this visual unity.

First time ever in this class and size, the twin individual rear seats fold completely to create a flat loading surface more than 2m long with 1200lt capacity. This is instrumental to fulfill the functional mission profile, which requires loading in full comfort a wide array of leisure equipment, including 4 full golfing bags with the rear seats up. An example of bespoke finish is the woven leather boot carpet offering superior endurance and coordinated with the special luggage set.

Manufacturing
When digital technologies are blended with traditional manufacturing skills, a fascinating process emerges that is typical for Touring Superleggera. A discriminating factor for traditional coach building was and is the vast amount of handwork that is involved in the creation of a new body. In this process, multiple practical solutions are also found for a wide variety of minor technical issues. This includes quick, practical solutions based on years-long experience, common sense and an expert eye.

Performance
The Bentley Continental Flying Star by Touring inherits the chassis of the Continental GTC. The 6-liter, W12 engine is available either in the 560HP version which delivers 650NM of torque at 1600rpm or the GTC Speed variant which delivers a massive 750Nm from 610HP. The car exhibited at the 2010 Geneva Motor Show featured the GTC Speed specifications.

Performance braking, cornering and traction functions mesh together to provide precise and immediate driving control under extreme or difficult conditions.
Self-adjusting air springs and electronic dampers operate independently for each wheel. Allwheel drive promotes advanced traction.

Homologation
The model is CEE homologated according to the new low-volume production directive. For the first time since its introduction, the type approval was awarded without destructive test, using simulation and FEM-analysis.

Lexus GX 460, 2010

Lexus GX 460, 2010

 

 

Lexus has introduced an all-new, second-generation Lexus GX 460 luxury utility vehicle for 2010 that is more powerful, more efficient, quieter and more luxurious than the Lexus GX 470 model it replaces. The 2010 GX 460 achieves all of these significant developments while its 10 standard airbags and the available Pre-Collision System help enhance safety.

Positioned between the brand's LX 570 premium luxury utility vehicle and unibody-based Lexus RX models, the 2010 Lexus GX 460 combines "right sized" midsize packaging with family-friendly comfort and premium craftsmanship. The Lexus GX 460 has a standard seven-passenger configuration. Once again built with rugged body-on-frame construction, the 2010 Lexus GX 460 is also equipped with full-time four-wheel drive and the advanced Kinetic Dynamic Suspension System (KDSS) to help provide both exceptional on-road ride and handling and true off-road capability.

The 2010 Lexus GX 460 is powered by an all-new 4.6-liter V8 that is both more powerful and more efficient than the 4.7-liter V8 it replaces. The new engine produces 301 horsepower and 329 lb.-ft. of peak torque, and is teamed to a new six-speed automatic transmission with sequential shift. Combined city/highway fuel economy is improved by 13 percent to an EPA-estimated 17 mpg (vs. 15 mpg in the 2009 GX 470) -- better than other V8 luxury utility vehicles and competitive with some six-cylinder models. The Lexus GX 460 has an EPA-estimated 15 mpg city and 20 mpg highway.

With the same vehicle footprint as the Lexus GX 470 it replaces, the 2010 GX 460 provides a more versatile interior. The second row seat slides 4.1 inches fore/aft to maximize passenger and cargo carrying ability. The foldable and reclining second row seats also feature a 60/40 walk-in function to access the standard power fold-flat third row seats. The rear door window uses a flip-up glass panel for added convenience.

Luxury is enhanced in the 2010 Lexus GX 460 by an even quieter cabin, as well as new additional standard features and options. The 2010 Lexus GX 460 features standard heated and ventilated front seats for example. Among the new luxury options are semi-aniline leather, a heated steering wheel, and heated outer second-row seats. New multimedia features - both standard and optional - expand onboard family entertainment choices.

Engine/Transmission/Drivetrain/Performance
The 2010 Lexus GX 460 takes its model designation from an all-new 4.6-liter V8 engine. The new 32-valve DOHC engine features aluminum alloy cylinder heads and block with dual Variable Valve Timing with Intelligence (VVT-i), which controls valve timing and overlap on both the intake and exhaust camshafts to optimize power, fuel efficiency and emissions. (The previous 4.7 had VVT only on the intake camshafts.) Peak torque is also up for the new 4.6, now 329 lb.-ft. at 3,500 rpm vs. 323 lb.-ft. at 3,400 rpm for the 4.7-liter engine.

The new 4.6-liter V8 is teamed to a six-speed electronically controlled automatic transmission, compared to a five-speed automatic with the previous 4.7-liter, benefiting both performance and fuel economy. The new transmission fits in the same space as the previous five-speed and features a higher top gear ratio. The new powertrain helps make the 2010 Lexus GX 460 feel more responsive in everyday driving and quieter than the previous model. The 2010 Lexus GX 460 retains the same 6,500-lb. towing capacity as the GX 470 offered.

The Lexus GX 460 comes equipped with standard full-time four-wheel drive using an electronically controlled transfer case and a TORSEN® torque-sensing center differential. It also offers a low range for off-road driving. The TORSEN differential distributes power 40:60 under most driving conditions and changes the ratio as needed based on steering input and wheel slip.

The ability to change to a 30:70 ratio during steering maneuvers helps enhance vehicle tracking through curves. If the rear wheels spin, the center differential can change the ratio to 50:50 to help control the slippage. The TORSEN differential also helps make the Lexus GX 460 less prone to slippage caused by sudden changes in road-surface conditions, such as driving through a puddle or over an ice patch. The rear differential has also been strengthened for 2010.

Chassis/Body/Suspension/Tires/Brakes
The 2010 Lexus GX 460 is one of the few premium brand luxury utility vehicles that can deliver genuine trail driving capability. Combining that capability with Lexus luxury and on-road performance makes it even more exceptional. Lexus studied vehicle usage of current owners and found that many use their GX models for family hauling during the week and vacations and camping trips on weekends. They often tow a boat or watercraft and sometimes drive to areas with unpaved and rugged trails.

Like the previous GX 470, the 2010 GX 460 has robust body-on-frame construction and does not compromise on- or off-road performance; the high-strength chassis and dynamic suspension control technology support both.

The power rack-and-pinion steering system helps make it easier to maneuver the Lexus GX 460 in tight spaces. Rear Adjustable Height Control (AHC) enhances the vehicle's flexibility in a wide range of driving situations.

Kinetic Dynamic Suspension System (KDSS)
KDSS is standard on the Lexus GX 460, and enhanced for 2010 with steering and yaw sensors. By adjusting roll resistance provided by the front and rear stabilizer bars, KDSS can reduce maximum body-roll angle by as much as 50 percent to help enhance both on-road handling response and off-highway capability.

Using hydraulic cylinders acting on each stabilizer bar and linked by a pressure-sensing valve, KDSS reduces the degree of roll stiffness provided by the stabilizer bars in response to changing road conditions and driver inputs. Because KDSS allows the stabilizer bars to disengage in certain situations like off-road driving, the nominal stiffness of the bars can be notably increased to help reduce body-tilt and improve on-road handling.

During on-road cornering, when both front and rear cylinders are compressed, no fluid flows in the system and the stabilizer bars work conventionally to help reduce body lean. In off-road driving situations, KDSS allows the wheels on each axle to move with a larger degree of side-to-side independence, helping to minimize any tendency for wheel lift. When the Lexus GX 460 encounters an uneven surface, one compressed cylinder causes fluid to flow between the front and rear cylinders, allowing the stabilizer bars to move freely. That action increases wheel travel and articulation and helps to equalize wheel loading.

BMW Z4, 2010

BMW Z4, 2010

 

The latest in BMW's long and successful roadster family has been revealed.

The BMW Z4 is the first to come with a two-piece, electro-hydraulically operated Retractable Hard-Top roof that can be raised or lowered in 20 seconds. The new roadster is also the first vehicle to be offered with Adaptive M Suspension. Electronically controlled dampers offer three different configurations and lower the ride height by up to 10mm for a more dynamic drive. By way of comparison, the Sport+ setting of the new car is comparable to the outgoing Z4's standard ride comfort level.

The standard Drive Dynamic Control function is another first and allows the driver to alter, depending on model specification, the throttle and steering response, level of ride comfort, Dynamic Stability Control response and, on automatic or Double Clutch Transmission cars, gear change times.

Powering the new BMW Z4 is a choice of three six-cylinder powerplants. The range flagship is the current International Engine of the Year-winning 3.0-litre twin-turbocharged engine. Producing 306hp at 5,800rpm, the BMW Z4 sDrive35i powers its way from zero to 62mph in 5.2 seconds (5.1 seconds for a Double Clutch Transmission-equipped car) and on to an electronically-limited top speed of 155mph. The twin-turbocharged 2,979cc engine with high-precision direct injection technology produces 400Nm of torque from just 1,300rpm for effortless in-gear acceleration. The strong performance credentials are matched in terms of economy and emissions. The Z4 sDrive35i records a combined consumption figure of 30.1mpg (31.4mpg) and CO2 emissions of 219g/km (210g/km).

Joining this model in the launch line-up are the Z4 sDrive23i and the Z4 sDrive30i. Both use the same magnesium aluminium alloy engine with Double VANOS and VALVETRONIC technology, but with varying capacities. The 2,497cc entry-level Z4 sDrive23i produces 204hp at 6,400rpm and 250Nm of torque from 2,750rpm. This equates to a zero to 62mph time of 6.6 seconds (7.3 seconds for the Sport Automatic) and a top speed of 151mph (149mph). In contrast the Z4 sDrive23i is capable of 33.2mpg (34.4mpg) on the combined cycle and CO2 emissions of 199g/km (192g/km) respectively.

All three six-cylinder powerplants surpass the latest strict EU5 emissions standards.
The BMW Z4 sDrive30i comes with a 2,996cc powerplant offering 258hp at 6,600rpm and 310Nm of torque from 2,600rpm. The six-cylinder engine records a zero to 62mph time of 5.8 seconds (6.1 seconds for the Sports Automatic) and an electronically-limited top speed of 155mph. Like the Z4 sDrive23i, the Z4 sDrive30i posts impressive combined consumption and CO2 emissions figures, recording 33.2mpg (34.0mpg) and 199g/km (195g/km). Transmitting the power to the road in all three Z4s is a six-speed manual gearbox as standard.

The efficient dynamics
All of the latest BMW Z4s come as standard with facets of BMW's award-winning EfficientDynamics programme. Technologies that improve engine performance while enhancing economy and cutting emissions include Brake Energy Regeneration, Electric Power Steering with Servotronic, Reduced Rolling Resistance Tyres, on-demand control of the engine's ancillaries and Optimum Shift Indicator on manual transmission cars. The BMW Z4 also adheres to a philosophy of lightweight construction with the front suspension and subframe being largely made from aluminium.

The enhanced packaging
The new BMW Z4 is larger than its predecessor measuring 148mm longer at 4,239mm and 9mm wider at 1,790mm, and this results in greater interior space and luggage capacity. With the roof up, headroom has been increased by 44mm while the greater car width and design enhancements have led to 20mm more shoulder room and 43mm more elbow room.

For the first time on a BMW Z4 there is a bespoke storage facility located behind the driver and passenger seats. This approximate 15.5-litre single compartment stretches the width of the car's interior and features netting to hold the contents in place. It can be complemented by an optional Storage Package that adds further stowage capacity. BMW's latest generation of iDrive makes its first appearance on a Z4. The BMW Professional Multimedia Navigation system features a hard disc drive capable of 12Gb of audio file storage and BMW ConnectedDrive functionality. The system also comes with eight programmable Favourite buttons as system shortcuts.
The unique roof construction of the BMW Z4 creates a boot that varies in capacity from 180 to 310 litres - large enough to stow a full set of golf clubs. For the first time on a BMW Z4 customers can specify a through-loading system for additional storage capability. A hatch between the two seats permits a second full set of golf clubs to be carried.
Driver visibility in the BMW Z4 has also been improved. All round visibility is up by 14 per cent while, courtesy of the four electric windows creating a larger glasshouse, side visibility is up 40 per cent. The Retractable Hard-Top roof features a glass rear window and this too improves visibility by 52 per cent.

BMW Z4, 2010

BMW Z4, 2010

 

The latest in BMW's long and successful roadster family has been revealed.

The BMW Z4 is the first to come with a two-piece, electro-hydraulically operated Retractable Hard-Top roof that can be raised or lowered in 20 seconds. The new roadster is also the first vehicle to be offered with Adaptive M Suspension. Electronically controlled dampers offer three different configurations and lower the ride height by up to 10mm for a more dynamic drive. By way of comparison, the Sport+ setting of the new car is comparable to the outgoing Z4's standard ride comfort level.

The standard Drive Dynamic Control function is another first and allows the driver to alter, depending on model specification, the throttle and steering response, level of ride comfort, Dynamic Stability Control response and, on automatic or Double Clutch Transmission cars, gear change times.
