Greenpower is a series of events which aims to promote greater interest in young people to follow careers in the fields of engineering and technology. The 2008 Greenpower corporate challenge held yesterday was the first race of the season. 25 teams entered, comprising 15 school entries and 10 company teams. The Bentley team achieved their goal of completing the four hour race, despite some technical difficulties in the first section. The award was given in recognition of their excellent team spirit which they showed in overcoming these initial technical challenges. The F24+ season consists of eight 90-minute endurance race events which will culminate in a grand final at Goodwood in October. Race tracks on the F24+ schedule include Dunsfold, Rockingham, Croft and Aintree.
The Bentley Motors team is composed of nine of the company's apprentices who are all following a three or four year apprenticeship scheme at the factory in Crewe. Margaret Cheshire, Head of People and Organisational Development at Bentley Motors said, "It's fantastic that the apprentices are not only gaining the technical skills associated with building a car but are also increasing their knowledge of other areas of the business such as finance, purchasing and public relations." She continued, "It's all about giving the individuals knowledge and expertise to be successful in their future careers after the completion of the Bentley apprenticeship programme."
Having taken the initiative themselves to compete in the Greenpower challenge the apprentices have devoted weekends and evenings for the past ten months taking full responsibility for all aspects of the car's development. Three team members acted as drivers on race day, the rest of the team provided essential back-up support in the pits.
Tom Hodgson, Greenpower team manager added, "In building the car we pooled the expertise and resources from across the business to produce a project of which we're all proud. Having completed our first race we now know what we have to do to be successful for the rest of the 2008 Greenpower season. The experience of developing a project from idea to race-day was exhilarating. It was also hugely satisfying to see the positive support from sponsors keen to help the Bentley team".

The crew at Crewe went on a serious sales and profit rampage in 2007 as it raced against a faltering world economy, and came out the winner. Bentley Motors says last year was a record year for it as it raised revenues by 2.7 percent to €1.37 billion. Operating profit went to an unprecedented €155 million.
“2007 was a milestone in the history of Bentley as we passed the 10,000 units for the first time,” commented Bentley Chairman and CEO Dr Franz-Josef Paefgen, “Five years ago we were selling only 1000 units but the development of a strong product line has seen the Company attract new customers in greater numbers. 2007 saw strong growth both in mature markets, such as Germany, the UK and the US, as well as in emerging markets, such as China and Russia.”
Bentley says it’s confident of another profitable year in 2008, despite an economic downturn in most major markets in the world. Models Continental, brand new Brooklands and Arnage ranges promise even greater success for the coming year. Paefgen does not feel this model flood is in any way eroding his brand’s exclusivity.
he world’s most exclusive coupé: limited to just 550 cars
The most powerful V8 engine Bentley has ever produced
Inspired by the exploits of the ‘Bentley Boys’ at the famous Brooklands racetrack
Powerful, muscular and rakish with classic British proportions
The Bentley Brooklands is a stunning new model that marks the company’s return to the luxury coupé market and reaffirms its reputation as creator of the world’s most exclusive coupés. It is the ultimate Bentley: a stylish, four-seat, grand touring coupe with classic British proportions and muscular performance.
Bentley’s chairman Dr Franz-Josef Paefgen describes the motivation behind the new coupé: “Bentley’s proud sporting pedigree, forged by the exploits of the immortal ‘Bentley Boys’ on the famous Brooklands racetrack in the 1920s, was the inspiration for our new coupé, capturing all the style, power and splendour of that era.” *
Sporting design cues are matched by the phenomenal performance engineering of Bentley’s legendary Crewe-built V8 engine. The new Bentley Brooklands possesses the most powerful V8 the company has ever produced – a 530bhp, twin-turbocharged 6.75-litre unit that also produces a prodigious 1050Nm of torque.
Each Brooklands coupé will be hand-assembled, employing traditional coach-building techniques and the craftsmanship skills in wood veneer and leather hide for which Bentley is renowned. To ensure exclusivity, lifetime production will be strictly limited to just 550 cars, with deliveries expected to start in the first half of 2008.
Exterior Design: Classic British Proportions
Bentley’s rich coupé heritage provided the stimulus for Director of Styling, Dirk van Braeckel and his design team. For van Braeckel, the task was very clear: “To create a powerful, muscular and rakish grand touring coupé with classic British proportions, in the finest Bentley tradition.”
While the new Brooklands is influenced by Bentley’s fine coupé lineage, its design and engineering are thoroughly contemporary. The proportions of long bonnet, short front overhang and long rear overhang achieve the design objective perfectly, while the low roofline, steeply raked screens and pillarless side glass convey both power and movement.
As the Brooklands will be built in very limited volume, the designers were able to introduce unique features that necessitate specialist coach-building techniques, as Programme Director, Ashley Wickham, reveals: “The Brooklands’ beautiful flowing lines are testament to the traditional coach-building skills and craftsmanship of Crewe’s highly talented workforce.”
The ‘floating’ rear screen, for example, is a contemporary take on traditional coachbuilt Bentleys. The lower edge of the screen sits well above the upper edge of the boot lid to provide a flowing, flawless line to the back of the car. This can only be achieved by individually hand-welding the rear wings to the C-pillars.
The fitment of 20-inch diameter wheels as standard, signalling the surefooted, robust and dynamic character of the new model, reaffirms the powerful stance of the new Bentley coupé.
Interior Design: Peerless Craftsmanship with a Sporting Character
Dirk van Braeckel describes the mission for the Bentley interior design team: “To create the perfect Bentley coupé: sumptuous hand-crafted luxury with a distinctly sporting character.”
As in every Bentley, peerless craftsmanship is to the fore, enhanced by the warmth and richness of the finest natural materials. To tailor for their individual requirements, customers may choose from an extensive palette of hides, veneers, carpet tones and seat belt colours.
Its four-seat architecture and deeply bolstered seats lend the Brooklands’ interior a distinctly sporting atmosphere, complemented by design accents such as aluminium foot pedals and footrest. A new, single-piece, hide-trimmed roof lining flows uninterrupted from the front windscreen all the way to the rear of the car, mirroring the long, sleek profile of the elegant exterior.
The interior designers sought to offer the very highest levels of comfort and legroom, in true Bentley grand touring tradition, while the pillarless window design enhances the feeling of space.
The Brooklands’ cabin is wider both front and rear than the previous Bentley Continental R coupé – the rear by 10 percent – and it easily exceeds the interior leg, knee and headroom of any luxury coupe on sale today. This allows four adults to be accommodated in supreme comfort. Individual rear seats with electrically operated sliding cushions, set further back than on the Azure, are separated by a new centre console, incorporating both storage and cup holders.
Most powerful Crewe-built V8 ever – 530bhp, 1050Nm
Beneath its muscular, rakish, coach-built body lies the most powerful Crewe-builtV8 engine ever produced, developing 530bhp. Maximum torque is an astonishing 1050Nm, the highest ever developed by a production V8 engine. Although performance figures are subject to final confirmation as part of the on-going development programme, the new Bentley coupé will deliver supercar levels of in-gear acceleration combined with Arnage refinement.
At the beginning of the project, Dr Ulrich Eichhorn, Member of the Board, Engineering, tasked his power train specialists to deliver an extraordinary driving experience in the Bentley coupé tradition: “Exhilarating, effortless, accessible performance for those truly passionate about their driving was our prime objective.”
Launched in the Bentley S2 saloon in 1959 with a capacity of 6.23 litres, the legendary, Crewe-built V8 engine has continually evolved. The first V8 was very advanced for its time with an all-aluminium construction, a five-bearing crankshaft and a well-supported camshaft, producing nearly 200bhp and 400Nm of torque. The result was a light and supple powertrain that produced maximum torque at low engine speeds, the hallmark of every Bentley ever produced.
1969 saw the capacity grow to 6.75 litres, where it remains to this day, but by far the most significant change came in 1982, with the introduction of a turbocharger to create the near-300bhp Mulsanne Turbo, a car that transformed the image of Bentley. In 1999, the single turbo engine, by now featuring port injection and charge cooling, was installed in Arnage, with twin turbos arriving in 2002, developing up to 450bhp.
For the 2007 model Arnage, the V8 engine saw a step-change in performance and refinement which became the starting point for the new Bentley Brooklands. A re-profiled camshaft and new, low-inertia turbochargers, which operate with greater efficiency at lower engine speeds have resulted in reduced turbo lag, enhancing that prodigious wave of torque at any revs, the hallmark of a true Bentley. These changes extend the power potential of the V8 in the Arnage to 500bhp and 1000Nm of torque. For the Bentley Brooklands, further component optimisation and engine calibration ensure record power and torque levels from this hand-assembled engine.
As with the latest Arnage, the V8 engine is mated to a six-speed transmission with strengthened casing that transforms the way in which both parts of the drive train communicate. A sophisticated, locking torque converter and ESP system ensure that the driver can readily access the prodigious power. A semi-automatic function allows manual gear selection for even greater driver control.
*The challenging Brooklands banked racetrack, which this year celebrates its centenary, was the birthplace of British motor racing. During the 1920s and early thirties, Brooklands, located in Surrey, England, was the scene of some of Bentley’s greatest racing triumphs, forging an inextricable link between the company’s motorsport heritage and this historic race circuit.
In times where mass-production cars are considered to be the only alternative to future of the automobile, Italian carrozieri keep teaching us all a little more on elegance and style. Although not all lessons are worth paying attention to, such as the family struggle that may kill Bertone, there are some that are worth waiting for. This is the case with Zagato’s last creation, the Bentley GTZ .
Back in December Zagato announced that they would be working with Bentley on a new project but failed to mention which Bentley। Now we know, as we guessed in December it will indeed be the Bentley continental GT Speed.
