In order to change the Bentley Continental Supersports`s apparel, American tuner WheelsBoutique gave this car a set of 22 inch HRE 940R`s wheels with a black face paint finish and equipped with Pirelli PZero tires.

To complete the masterpiece, they made color matched front-lip and interior. To complete the Bentley`s make-over, WheelsBoutique added a RSC exhaust and mounted to the engine a new Evo MS Tune system, a Mansory air filter and Renntech lowering module.

Bentley Motors has unveiled two unique Continental models, which have been engineered and designed exclusively for the Middle East market. These special edition cars have been created at Bentley’s Crewe headquarters with both models offering a range of striking features specially commissioned for Arabic customers.

The Middle East market now represents 10 per cent of Bentley retail sales globally and has doubled its contribution to the worldwide percentage of sales over the last five years. This trend has continued despite the recent global recession.

From Bentley’s first dealership in Dubai, the network has grown to become nine-strong in 2010, with dealers in Dubai, Doha, Abu Dhabi, Kuwait, Bahrain, Oman, Jeddah, Riyadh and Al Khobar. These two new models have been launched specifically for this unique market.

The Continental Flying Spur Arabia and the Continental Flying Spur Speed Arabia retain all the potent performance of the company’s Continental Flying Spur and Spur Speed, the world’s fastest luxury four-door saloon, but with a range of additional exterior and interior features to create the ultimate in distinguished, elegant driving developed for the Arabic market.

Both cars are further distinguished by some subtle exterior and interior ‘Arabia’ motifs. These include an exterior front fender badge, tread plate and ashtray lid badge – all bearing the Arabia signature.

The class-leading performance of the W12, 6-litre engine is in no way diminished. The Flying Spur Arabia is capable of achieving a potential top speed of 312 km/h and a 0-100 km/h sprint time of just 4.9 seconds. The Flying Spur Speed Arabia offers a more powerful 600 bhp (610 ps, 449 kW) version of Bentley’s highly acclaimed W12 with 553 lb-ft (750 Nm) of torque. This is a 9 per cent increase in power and 15 per cent increase in torque over its sister model, and will drive from 0-100 km/h in 4.8 seconds with a top speed of 322 km/h.

Unique wheels are also offered on both models. The Continental Flying Spur Arabia is designed with an elegant 14-spoke diamond alloy wheel, which has incredible strength through a small surface area and allows the best possible flow of air to the brake discs.

For the Continental Flying Spur Speed Arabia, vibrant and sporty, bright silver, 10-spoke, 20-inch wheels are included, and are also compatible with optional carbon ceramic brakes.

Bentley’s ability to add extra, well-executed touches of luxury can be found in the ventilated fluted seats that effectively cool and warm the body, helping driver and passengers always to stay comfortable. The craftsmanship features which are synonymous with the Bentley name also include veneered picnic tables to the rear of front seats inset with vanity mirrors, chrome inlay strips to the door waistrails and deep-pile carpet mats with hide trimming. To surprise and delight the customer, even the fuel cap has been designed with jewellery in mind and is engineered in bright chrome with the famous ‘B’ badge.

For convenience, an additional valet key is offered with limited functionality that allows the car to be driven without giving access to the boot or glove box. This provides secure storage of personal belongings when using valet parking services.

Further options that offer the luxury and refinement to the customer include Adaptive Cruise Control with ‘follow to stop feature’, a rear-view camera, the iPod interface linked to the infotainment system and privacy phone handsets in the front and rear of the car.

Geoff Dowding, Regional Director, Asia and Middle East, comments:

“We have created these exclusive new models for our Arabic customers in recognition of the growing importance of these influential customers. Bentley has a long and proud tradition of being able to design, engineer and personalise our cars to the individual styling and driving tastes of our customers and these special-edition Bentleys showcase these skills for the Middle East Market”.

Wheelsandmore, german individual tuner for sports- and supersportscars, has revealed their custom modifications on the Bentley Continental Supersports.

With serial power about 630 hp the Bentley Continental Supersports already is the most powerful and fastest sportscoupe ever built by Bentley. But Wheelsandmore thought of much more and developed an ecu upgrade, combined with a handmade, stainless steel exhaust system. With special sportcatalysts, the ecu upgrade and within a remote controlled valve flap system, they increased the power up to 702 bhp and 650 lb-ft of torque.

As the Bentley Supersports is not only coming with the biggest engine, but also with one of the biggest carbon-ceramic brakes, measuring 16.54 inches, Wheelsandmore got to use all their experience and know how to construct special wheels for perfect handling and outstanding visual appearance. The 3-piece lightweight wheel set is outfitted with „C-Sport” model sizing 10,5×21″ with Dunlop Sport Maxx tyres front and rear, wearing an enormous 4,5″ outisde lip in the rear. A special tyre approval allows a giant highspeed at 209 mph. In this case the wheels are painted completely matte black with a red racestripe, but wheelsandmore is able to offer unlimited colour and surface combinations.

Finally the suspension can be switched up and down by using an electronic lowering module from Wheelsandmore called „LowMaXX”, which lifts up the car automatically around 0.79 inches at a speed of 44 mph to recover comfort and safety.

It takes an avid and passionate collector, with a taste for special coach building, to be at the basis of a project like the Bentley Continental Flying Star by Touring. Exactly such a person contacted Touring Superleggera in early 2008.

An interesting initial creative process emerged involving parameters for design, proportions, vehicle concepts and – last but not least- feasibility and technical factors.

Many steps from design to execution were shared with the customer, who contributed with his own ideas and taste to personalize the project and create a unique automobile.

A basic idea was formed by the desire to diversify Bentley’s very successful Continental model range, and to explore new concepts.

The transformation of a 2-door coupe, by expanding the roof line and enlarging the interior dimensions, has led to a design concept baptised as shooting brake: a sports car featuring enough space to join a hunting party or a golf tournament with elegance and efficiency. Touring Superleggera explored the same field back in 1966, resulting in the amazing Lamborghini Flying Star II prototype. It was a dramatic interpretation of a sports car based on a new 2-volume design, safeguarding the dynamic performance. The Flying Star reference is a Touring parameter of sportive elegance, applied to many famous cars since the companies’ start in 1926.

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 Touring 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.

All structural additions and modifications were thoroughly studied, using advanced simulation methods and FEM-analysis. As a parallel process, these data served for the homologation of the structural changes, including the new foldable rear seats. An important number of hard points from the basic car could be saved and carried-over. The engineering team at Carrozzeria Touring was particularly pleased with the quality assurance support from Bentley engineers.

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.

The overall result is perfectly in line with the Touring and Flying Star heritage: a timeless shape, a design statement combining elegance and sportiveness, with a strong and unmistakable own personality and individuality.

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.

The result is a final product entirely produced within the high quality parameters of today’s automotive industry.

From the A-pillar backwards, new exterior body panels were hand shaped in steel – including the roof, new wider rear wings, and the internal reinforcements of the complete rear section of the car. Aluminium was used for the door skins, and for the complete rear bonnet including its structure. New, handmade brightwork was added according to the new exterior design. The all new rear compartment required shaping of the foldable rear seats and a full set of interior panels, leather trimmed with meticulous care. Wide leather hides were selected with great attention to provide uniform finish to the vast continuous surfaces.

After inspection, the body in white was prepared and painted in the Touring state-of-the-art paint facilities. The final result underwent again a special final quality audit.

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 in Geneva Motor Show features the GCT 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.

Future Programme

Touring Superleggera undertakes a limited production run of up to 20 units of the Continental Flying Star. This series will be exclusively built to special order and customer specifications. The car is offered at a basic price of € 590.000 when based on a Continental GTC – 560 PS. Other versions on request.

The car will be serviced at the Bentley dealers. Bentley Motors and Touring Superleggera have developed a special mutual warranty program, which safeguards warranty clauses for both the basic car, and the transformation by Touring.

Personalisation

The customers are actively involved in the early stage to choose the specifications of their own unique automobile, ranging from bespoke cabinetry and trim to a wide choice of dedicated options. The accessory collection includes the Touring designed luggage set coordinated with the boot trim, and the distinctive Borrani X-Ray spoke wheels.

Blending advanced technology with craftsmanship, Borrani 20” 9.5j X-Ray spoke wheels provide distinctive design, precision and comfort. Featuring monolithic spun aluminium rim and hand assembled steel spokes, they can be tailored to the car’s painting and finish.

Louis de Fabribeckers, Head of Design

Responsible for the design team of the Flying Star project is the 32 years young Belgian designer Louis de Fabribeckers.

Graduated from the ISD of Valenciennes in France in Engineering Design, de Fabribeckers started to work with Touring in 2006 as project leader.

Under his hands, the Maserati based Bellagio and A8GCS Berlinetta projects materialized; the first one being a fastback, 5-door version of the Quattroporte model, and the second a magnificent concept for a light and compact, modern sports car. Both new projects were presented at the occasion of the 2008 Villa d’Este Concours d’Elégance. The A8GCS Berlinetta was granted the ‘Plus Belle Supercar de l’Année 2008’ award by the expert jury of the 24th. Festival Internationale de l’Automobile in Paris.

Louis de Fabribeckers lives and works in Milan.

FlexFuel technology now standard across Continental model range

• The Bentley Continental Supersports Convertible is the fastest, most potent drop-top Bentley ever built – 0-60mph in just 3.9 seconds (0-100km/h in 4.2 seconds) and a top speed of 202mph (325km/h). It is also the fastest four-seat convertible in the world.
• The Supersports is the extreme Bentley convertible, offering a highly focussed, pure Bentley driving experience.
• Muscular styling reflects the Bentley Continental Supersports Convertible’s supercar personality with the practicality and elegance of four-seat accommodation.
• The standardisation of pioneering FlexFuel technology across the 2011 Continental model range reaffirms Bentley’s on-going environmental commitment to make all its cars biofuel- compatible by 2012.

The Bentley Continental Supersports Convertible further strengthens Bentley’s supercar range, following the introduction of the Continental Supersports Coupé in 2009. The new Bentley Continental Supersports Convertible, with the same 630PS (621bhp/463kW) twin-turbocharged W12 engine, is the fastest, most potent drop-top Bentley has ever built, offering the ultimate Bentley driving experience in the world’s most dramatic convertible. The inspiration for the ‘Supersports’ name is the 1925 Bentley Supersports, a race-bred version of the iconic Bentley 3-litre, that delivered 85bhp when more ordinary cars were equipped with a modest 15bhp. It was also the first production car to reach 100mph – extreme performance in its day.

The new, muscular four-seat Bentley Continental Supersports Convertible is unmistakably Bentley in its design and craftsmanship but its interior signifies a dramatic re-interpretation of Bentley luxury. Satin-finished carbon fibre, Alcantara™ and ‘Soft Grip’ leather create a unique ambience with a distinctly sporting and contemporary style.

All models in the Continental model range, including the new Bentley Continental Supersports Convertible are now capable of running on both petrol (gasoline) and E85 bioethanol or any combination of the two, reaffirming Bentley’s ongoing commitment to make all its cars bio-fuel compatible by 2012. Pioneered by the Supersports Coupe, this FlexFuel technology offers a reduction of up to 70 per cent in CO2 emissions on a ‘well-to-wheel’ basis, a measure of a fuel’s net contribution to the atmosphere, not just tailpipe emissions.

To ensure seamless power delivery, the on-board 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.

Bentley Chairman and Chief Executive Dr Franz-Josef Paefgen welcomes the new addition to the Bentley range, as well as the standardisation of the FlexFuel W12 engine on all 2011 Continental models: “The new Bentley Continental Supersports Convertible blends thrilling performance and dramatic styling with luxury and practicality in the Bentley open-top tradition. Extreme power combines with pioneering FlexFuel technology, now shared with all Continental models, reflecting Bentley’s ongoing commitment to more environmental motoring.”

THE CONTINENTAL SUPERSPORTS CONVERTIBLE – IN DETAIL

The new Bentley Continental Supersports Convertible is a car that must be driven to be fully understood. Behind the wheel it is immediately clear that a Supersports Bentley is a ‘fusion of extremes’ – the ultimate in extreme performance, every day practicality and unrivalled hand-crafted luxury.

Bentley’s Supersports programme began as an ‘under the radar’ project exploring the possibilities of weight reduction on the Continental GT Coupé but with more power and torque. The largely experimental project soon crystallised into an official new car programme, driven by the passion and enthusiasm of a small group of Bentley engineers and designers. Now the Bentley Continental Supersports Convertible has received the same focus and the results are equally dramatic. Dr Ulrich Eichhorn, Member of the Board, Engineering explains the thinking behind the project: “The ‘extreme’ Bentley stable now has a new occupant in the form of the Bentley Continental Supersports Convertible – a car every bit as purposeful and potent as the Coupé but with the panache of roof-down motoring.”

A highly focussed, pure Bentley driving experience

With 630PS (621bhp) and 800Nm (590lb ft) of torque from its pioneering FlexFuel engine and new ‘Quickshift’ transmission, the Bentley Continental Supersports Convertible is the fastest drop-top Bentley has ever built. It accelerates from 0-60mph in 3.9 seconds (0-100km/h in 4.2 seconds) and, conditions permitting, can continue onto a top speed of 202mph (325km/h).

The increased power and torque are transmitted to the all-wheel drive system via an uprated and rapid six-speed Quickshift transmission, which more than halves shift times (to just 93 milliseconds) and maximises the new Convertible’s enormous potential. The revised gearbox also has the ability to deliver double downshifts (sixth to fourth gear, for example) and improves acceleration across the entire gear range. To cope with the additional power and torque, the planetary gear set of the ZF transmission is also strengthened.

Positive torque during downshifts is achieved through engine and gearbox electronic controller interaction for extra throttle and fuel injection during the overrun. During transmission upshifts, fuel and ignition are cut momentarily to give faster mechanical shift times through torque reduction, also improving shift quality and durability. The extreme performance of the Superports Convertible is matched by precise, agile handling, while retaining class-leading levels of ride comfort and refinement. Developed from the GTC Speed, chassis enhancements include retuning of the electronic Continuous Damping Control (CDC) system, stiffer front suspension bushes and uprated rear anti-roll bar. The Bentley Continental Supersports Convertible also shares its ride height with the GTC Speed, sitting 10mm (0.4in) lower at the front and 15mm (0.6in) lower at the rear than the standard GTC.

The front suspension trailing lever features a new design of hydraulic bush, 33 per cent stiffer than those of GTC Speed, for improved steering response while the uprated rear anti-roll bar provides improved body control and turn-in response. The retuned CDC system provides enhanced control of body movement to strike the optimum balance between agile handling and ride comfort during all driving manoeuvres. Agility is further sharpened by a 40:60 rear-biased torque split for the all-wheel drive system which reduces understeer during hard cornering and allows the experienced driver to modulate the car’s line and balance via precise throttle control.

The 9.5Jx20-inch forged alloy wheels, shared with the Supersports Coupé, offer a weight saving of 10kg (22lb) per car, reducing unsprung and rotating mass while the open 10-spoke design offers superior brake cooling. The rear wheels have a 25mm (1 inch) greater offset resulting in a 50mm (2inches) increase in the rear track, further benefiting handling and stability. The lightweight wheels are fitted with 275/35 ZR 20 Pirelli Ultra-High Performance tyres, providing excellent steering response. The standard-fit tyre monitoring system allows the driver to select tyres type and speed range parameters. As well as monitoring pressures, the system warns drivers if their speed is too high for the tyre pressures or if tyre speed ratings are exceeded on winter tyres.

The Bentley Continental Supersports Convertible features an advanced electronic stability programme (ESP) that moderates intervention at low speeds, exploiting the potential of the more powerful engine and enhanced chassis, improving driver interaction and control. The new ESP also provides faster reinstatement of engine torque after intervention, giving the spirited driver greater control. The target slip is increased at greater than 90 per cent throttle to utilise all available longitudinal grip.

Corner exit agility is thereby also enhanced for increased driver involvement. Together the chassis, tyre and track changes deliver improved grip, turn-in and agility. Carbon ceramic brakes are standard fitment and provide a reduction in rotating and unsprung mass of 20kg (44lb) from the front axle, benefiting steering response, grip and ride comfort. The large diameter (420mm front, 356mm rear) lightweight discs and eight-piston calipers offer fade-resistant

braking performance with minimal disc distortion under high thermal conditions. Pedal feel is also improved with shorter travel, high effectiveness and a precise pressure point. Designing the ‘extreme’ Bentley convertible – where form follows function The evolution of the Bentley Continental Supersports Convertible’s design is very much a case of form following function, with new purposeful sculptural forms signalling the engineering changes beneath the skin. Key engineering-led design changes to the Supersports include:

• Revised front air intakes and new bonnet vents to improve airflow and cooling
• Flared rear wings to accommodate wider rear track
• Discreet bootlid spoiler benefitting aerodynamic balance at high speeds

The increased power and torque of the W12 engine necessitated an additional 10 per cent airflow to the twin turbocharger intercoolers and cooling system. With extensive use of Computational Fluid Dynamics techniques, Bentley’s designers responded with a purposeful and dramatic style, featuring large vertical intake apertures. Twin bonnet vents were added to ensure positive air extraction. Similarly, all-new flared rear wings that accommodate the 50mm (2 inches) wider rear track are designed to emphasise the powerful stance of this ultra-high performance Convertible. The resultant Bentley Continental Supersports Convertible style combines the looks of the graceful Continental GTC with a wide, low and muscular appearance that reflects its more extreme character.

The Bentley Continental Supersports Convertible, in common with its Coupé stablemate, occupies a position within the Bentley portfolio which is all its own, as Raul Pires, Head of Exterior Design, explains. “The Supersports Convertible and Coupé are the ultimate driver’s Bentleys and that is reflected in unique design cues that provide a bold, sporting look, from whatever angle the cars are admired. Even from 50 metres behind on a dark road, you can just tell it’s a Supersports.”

From the front, the radiator, lower grille and dual bonnet vents are finished in a striking Smoked Steel finish. Derived from an innovative technology normally used to apply a coating to luxury watches and specialised industrial tools, Physical Vapour Deposition (PVD) is a complex and time-consuming process that involves vaporised metal being deposited onto the surface of, in this case, stainless steel. Giving a darker, more solid appearance, it is the first use of a PVD finish on stainless steel in the car industry. In addition to the Smoked Steel finishes, a gloss black finish to the headlamp casings and rear lamp clusters gives the Bentley Continental Supersports Convertible’s distinctive face and muscular rear additional visual impact.

Restyled – and more aerodynamic – door mirrors match the exterior paint choice and the window and door surrounds replace polished stainless steel with a Smoked Steel finish to match the front grille. Eye-catching, black gloss Bentley-branded brake calipers act on the carbon ceramic brakes. Surrounding the brakes are the unique 20-inch, forged alloy wheels with Smoked Steel-finish which are exclusive to Supersports models. Large diameter tailpipe trims round out the car’s purposeful stance when viewed from the rear. Beneath the bonnet Supersports badges grace the cover of the 630PS (621bhp) W12 engine.

The Bentley Continental Supersports Convertible has an electrically operated, three-layer fabric hood with advanced acoustic insulation to provide superb levels of refinement and comfort when raised. A choice of eight hood colours are available, including a new Dark Grey Metallic option, which is achieved by weaving a ‘grey’ acrylic fibre with a semi-transparent ‘metallic effect’ fibre in a twill weave construction to create a directional colour effect.

A re-interpretation of Bentley craftsmanship

Inside the Supersports Convertible, the cockpit is a dramatic execution of iconic Bentley design displayed in its full glory every time the roof is lowered. Dirk van Braeckel, Director of Design and Styling, describes the approach taken by his interior design team: “The design team has fully embraced the spirit of Supersports to create a dramatic interpretation of Bentley luxury for the new Convertible where traditional craftsmanship and fine detailing are given a very different interpretation. Leather hides combine with new materials for Bentley such as satin-finished carbon fibre and Alcantara™ to create a unique ambience with a distinctly sporting and contemporary style.” Lightweight carbon fibre is featured throughout the cabin, from the unique carbon-weave treadplates with Supersports script in both doorwells to the sculpted lightweight sports front seats, which feature a carbon fibre clamshell back and Diamond-quilted Alcantara. Each seat weighs just 21kg and, in a typical example of attention to detail, the visible weave in the carbon fibre has a ‘Bentley-specific’ density to ensure the perfect visual finish. The Continental Supersports is the first Bentley to offer a combination of soft-grip leather and performance-enhancing Alcantara™ alongside the leather hide. Alcantara™ is favoured by racing teams for its ability to provide additional grip under extreme conditions, such as cornering. But it is also sensational to look at, as well as being immensely supportive on the road or track.

The Alcantara™ applied to the rear compartment, door panels and seat facings is quilted and in the Supersports marks the return of the much smaller ‘diamond’ upholstery pattern from Bentleys of old. To further highlight the car’s sporting nature, the steering wheel and gear lever are trimmed in new ‘Soft Grip’ leather with extra grip for a supercar feel, and drilled alloy sports pedals stand out in the driver’s footwell.

FlexFuel technology introduced on all 2011 Continental models

FlexFuel technology, pioneered on the Continental Supersports Coupé in 2009, is now extended to the complete 2011 Continental range, including the new Bentley Continental Supersports Convertible. The W12 6-litre power unit now has the technology to run on petrol, E85 bioethanol or any mix of these two fuels – all from a single tank.Bioethanol is blended with petrol in a variety of percentages ranging from E10 (10 per cent bioethanol) to the most widely known, E85, a ratio of 85% bioethanol to 15 per cent petrol to ensure cold-start capability.

Bioethanol presents other unique engineering challenges compared with petrol, due to its chemical composition and characteristics. E85 biofuel has a very high octane rating of 105 but a lower energy content that requires a 30 per cent increase in the engine fuel flow rate. This necessitated a complete review of the fuel system to identify and, if required, replace components deemed to be insufficiently resistant to the properties of ethanol.

Increased fuel flow is achieved through a returnless fuel system, twin variable flow fuel pumps and a new closed loop fuel rail design with pressure sensor. For the fuel system all O-rings, seals, gaskets and pipes are new while new valve coatings and hardened valve seat material provide additional lubrication. New spark plugs with a wider heat range allow for slower combustion. A sensor in the fuel supply system detects the blending ratio in real time and varies the engine mapping to ensure power, torque and emissions remain at the same levels whatever fuel is used.

FlexFuel offers the possibility of up to a 70 per cent reduction in CO2 net emissions on a ‘well to wheel’ basis, calculated by adding the CO2 emitted during the extraction and refining process (the ‘well’) with the CO2 released when the fuel is burnt during motoring (the ‘wheel’). Biofuels can be sourced from sugar cane or soyabean, or from “2nd generation” sources such as agricultural waste and forestry residues. As biofuels are not derived from fossil fuels, the CO2 released during combustion is reabsorbed by plants during the photosynthesis process, thus creating an unbroken energy cycle.

Enhanced choice for all Continental customers

In addition to the transition to all-FlexFuel engines, the Continental range receives a host of new exterior and interior specification enhancements for the 2011 models, which emphasise the unparalleled craftsmanship and materials that are used to create the exquisite interiors for which Bentley is renowned.

Six new colours are added to the Bentley colour palette (Citric, White Satin, Kingfisher, Magenta, Orange Flame and St James Red Pearl) and the Dark Grey Metallic Hood that is available on the new Supersports Convertible is also available on the Continental GTC models.

Traditional Bentley features such as seat piping and stitching options can be applied to the rich leather hides that are used to trim the cabins of every Continental. These include highly intricate fine line, cross and Z-stitching to decorate the seats, door panels and front console. A new Premium Pack for the four-door Flying Spur is available as a cost option and includes beautiful veneered picnic tables with vanity mirrors, a Mulliner ‘jewelled’ alloy fuel filler cap and chrome inlay strips to the door waistrails. Customers can also choose from lambswool rugs or deep pile carpet mats with leather hide binding to the edges.

Convenience Packs are available for both the Continental GT, Continental GTC, Flying Spur and Flying Spur Speed models. On the GT and GTC models this includes Adaptive Cruise Control with ‘Follow to Stop’ feature, an iPod™ interface linked to the Infotainment system, massage function to the front seats, a front privacy telephone handset, rear-view camera and Valet key. For Flying Spur models, the Convenience Pack also includes an additional rear privacy handset. The massage function for the front seats is already standard on this model.

Finally a new automatically opening and closing closing Powerboot is now standard on the new Continental Flying Spur and GTC models (not on Supersports versions).
