Bentley Continental SuperSports: 621HP and 204MPH Flex-Fuel Supercar

Bentley has revealed the fastest and most powerful model in its 90-year history, the new 621HP Continental Supersports that will make its premiere in Geneva with sales following in most markets from autumn 2009 and in the U.S., in the summer of 2010. The Continental Supersports, whose name is inspired by the firm's 1925 two-seater 3-litre Supersports model, is powered by a 6.0-liter W12 engine capable of running on either petrol and E85 biofuel or any combination of the two. Bentley supports that the E85 biofuel can offer a reduction of up to 70 per cent in CO2

So does that make the Supersport "green"? Well, definitely not compared to a Prius or even a conventional family car for that matter, but it's supposed to be green for the levels of performance and luxury it offers. For the record, the Continental Supersports has a combined fuel economy of 17.3 mpg UK which comes to 14.4mpg US or 16.3 lt / 100km, with CO2 emissions of (ahem...) 388 g/km.

The Superports' 6.0-litre W12 twin-turbocharged engine produces 621-horsepower at 6,000 rev and a massive 800Nm (590 lb/ft) of torque at 1,700-5,600 rev. The W12 is matted to a revised ZF6HP26 automatic transmission with 'Quickshift' system that cuts shift times by 50% and enables double downshifts, helping the flex-fuel Continental accelerate from 0-60mph in 3.7 sec (0-100km/h in 3.9 sec) onto a top speed of 204mph or 329 km/h.

Bentley's engineers also put the Supersport on a strict diet achieving a weight reduction of 110kg or 243 lb compared with the Continental GT Speed. For example, the 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.

To better the coupe's driving dynamics, the engineering team performed an array of chassis enhancements including retuned steering and suspension, utilizing lighter weight components, retuned dampers and anti-roll bars. Additionally, 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.

The Supersports is distinguished from its Continental coupe stable mates by the newly designed bonnet, the flared wings and new dark-smoked steel finish to all exterior 'brightware', including front grilles, lamp bezels, window surrounds and wheels. Inside, the cockpit is adorned with carbon fibre and Alcantara.

Commenting on the new Supersports model, Dr Franz-Josef Paefgen, Bentley's Chairman and Chief Executive said; "The Continental Supersports reflects the passion and enthusiasm of Bentley's engineers and designers. This is the fastest, most extreme Bentley ever, dramatically styled to underline its supercar character. Importantly, it also pioneers the use of FlexFuel technology in the luxury sector."

The fastest most powerful Bentley in the company's 90-year history

6-litre W12 engine twin-turbocharged now produces 630PS (621 bhp/463 kW) at 6000 rev/min and 800 Nm (590 lb ft) of torque at 1700-5600 rev/min

• 0-60 mph in 3.7 seconds (0-100 km/h in 3.9 seconds)
  
• 0-100 mph (0-160 km/h) in 8.9 seconds
  
• 50-70 mph in 2.1 seconds
  
• 80-120 km/h in 2.6 seconds
  
• Top speed of 204 mph (329 km/h)
  

Continental Supersports reaffirms Bentley's environmental commitment by pioneering the use of biofuel in the luxury sector

• Capable of running on petrol and E85 biofuel or any combination of the two
  
• Power and torque remain constant whatever the ratio of petrol to E85 biofuel
  
• A Fuel Quality Sensor detects the blending ratio of the fuel in real time sending a signal to the engine control unit (ECU), initiating the correct engine mapping. This ensures all performance parameters remain balanced and consistent
  
• Offers a reduction in CO₂ emissions of up to 70% (well-to-wheel), a measure of a fuel's net contribution to the atmosphere, not just tailpipe emissions
  

Continental Supersports is the extreme Bentley, delivering a highly focused driving experience

• Revised ZF 6HP26 transmission with 'Quickshift' system that cuts shift times by 50% and enables double downshifts
  
• New 40/60 rear-biased torque split for the all-wheel drive system reduces understeer when powering out of bends and provides for better modulation of line and attitude by 'throttle steering'
  
• Uprated front suspension with aluminium forward levers, stiffer bushes together with retuned antiroll bar and Servotronic steering for sharper turn-in
  
• Revised Continuous Damping Control (CDC) for improved body control
  
• Unique lightweight, 20-inch, 10-spoke alloy wheels offer 10 kg (22 lb) weight saving per car, reducing unsprung and rotating mass and improving brake cooling. Increased 25 mm (I inch) offset on rear wheels improves grip and stability
  
• 275/35 ZR20 Pirelli Ultra High Performance tyres
  
• Advanced ESP system fully exploits potential of the most powerful W12 engine and improved chassis
  
• Standard-fit carbon-ceramic brakes – the largest and most powerful brakes ever fitted to a production car – contribute 20 kg (44 lb) weight saving
  
• 110 kg (243 lb) weight saving compared to Continental GT Speed
  

Continental Supersports combines the looks of the iconic GT with a distinctive style that reflects its supercar character

• Form follows function: distinctive centre air intake and vertical grilles feed larger volume of air (+ 10%) to turbocharger intercoolers while bonnet vents extract hot air from engine bay
  
• Subtly curved rear wheel arches with newly tooled side panels accommodate increased rear track of the uprated chassis and provide muscular stance
  
• Distinctive 'smoked steel finish' to all exterior 'brightware', including the first automotive application of 'Physical Vapour Deposition' to stainless steel
  
• Larger, twin elliptical exhaust tailpipes and rear valance with discreet vertical divider
  
• 2 new pearlescent and 2 new matt finish colours
  
• Unique driver-focused, two-seater cabin with lightweight sports seats, giving a 45 kg (99 lb) weight saving
  
• Rear seats replaced by stowage deck with carbon fibre luggage retaining beam
  
• AlcantaraTM, carbon fibre and 'Soft Touch' leather provide a very different interpretation of Bentley craftsmanship with choice of Single Tone and Duo Tone combinations
