Welcome to the launch of the Bentley Continental GT,
the world's fastest four seat coupe, the first all-new and unique
Bentley design for over 70 years and its most significant new model
since the very first Bentley, the 3-litre, was first seen back in
1919.
For Bentley Motors, the Continental GT is more than a product launch
as it is symbolic of the change that the company is going through.
It is the first offspring of a new family of cars, which deliver unparallelled
levels of refinement, craftsmanship and driver involvement - or as
Bentley describes this combination, the ultimate British Sporting
Grand Tourer.
Styling
The styling story of the Continental GT dates back to August 1999
when design director, Dirk van Braeckel was briefed to prepare a concept
for an all new Bentley coupé: one that would use 80 years of
Bentley design as its inspiration, yet look only to the future in
its shape. It took just four months - until just before Christmas
- when van Braeckel submitted his preferred design to the board of
Bentley Motors. It was approved on the spot.
The key to honouring Bentley's design past without creating a 'retro'
car, was to take the design philosophy that inspired cars such as
the Bentley Speed Six of 1928 and the 1952 R-type Continental and
use it in a contemporary context.
Bentley's design philosophy for the Continental GT can be quantified
as follows: the car must have a short front overhang and a dominant
bonnet expressed by the unusually large distance between the front
axle line and the A-pillar. The pillarless cabin needs to be sleek
and compact while the rear haunches should be taut and pronounced,
giving the impression of a crouching animal ready to pounce.
Overlaying these highlights is a design language from the hearts of
the styling team. It dictated that the Continental GT be styled to
be curvaceous and sinuous with a form that appears and disappears
like muscle on a gymnast's arm, sculptural yet lean.
The cabin of the Continental GT is designed to make Bentley devotees
and marque newcomers feel equally at home. Those familiar with the
Bentley way of doing things will be reassured by the expanses of top
quality hide and fine wood veneers; those for whom Bentley ownership
is a new experience will discover a new level of luxury, style and
effortless good taste.
Design
The design brief for the Continental GT was to create a car with as
much room as the most spacious coupés, equip it with the performance
of the world's most dynamic supercars and retain the whole within
compact dimensions.
There are many questions raised by such a demanding specification
and it took sizeable measures of blue sky thinking and detailed innovation
before it could be realised.
One key to maximising interior space is raising the so-called 'H'
point - the position in which the driver and front passenger hips
naturally sit, and which in all Bentleys is elevated above where it
would be in a conventional supercar. The benefits are many: first
it means the commanding driving position - another Bentley hallmark
- is retained and the driver and passenger's hip to heel angle is
as close to anatomical perfection as is possible. Finally, and critically,
a high and upright driving position liberates vital room in the back
for rear seat passengers.
The result is a true two plus two, a phrase rather devalued today
by being applied to cars with little more than a ledge behind the
front seats. In the Continental GT it means a car capable of carrying
two adults and two children in comfort for unlimited distances.
Another less obvious but no less important benefit of the Continental
GT's design is the omission of a B-pillar. There are many aesthetic
reasons for adopting the pillarless look, but for those inside looking
out and particularly those in the back, the unbroken expanse of glass
from the front to the rear of the cabin provides a feeling of great
space and airiness.
Even the 370 litre luggage capacity has only been achieved through
fresh thinking. In cars of this size, it is accepted practice to site
the fuel tank between the boot and rear seat, the Continental GT's
fuel tank, however, is under the floor of the car. It's a tricky piece
of design but there's no doubting the effectiveness of the result.
Not only is there enough boot space to swallow enough luggage for
a family fortnight away, if that holiday happens to be to the ski
slopes, it will take all four sets of skis inside the car or two pairs
of skis and a couple of snow boards. All of this mind, without having
to resort to an unsightly and insecure roof rack.
Design Technology
The Continental GT is the first Bentley to have been designed in the
virtual world. Using the very latest CATIA-based Computer Aided Design
(CAD) programmes, the Continental GT represents a huge step forward
in Bentley design technology. With all components existing in the
virtual world before a single one is created as a physical property,
it is possible to see how each part interacts with all the others,
illuminating problems and conflicts that, in the past, may never have
come to light until the part had been machined.
This process cuts down development time and costs and enables Bentley's
engineers to design in reliability and consistency in each component.
Indeed, one critical aspect of the design work now done in the virtual
world enables Bentley to produce theoretically perfect component designs
before the Data Control Model (DCM) is made.
The DCM is as close to a mathematically faultless physical model of
the interior and exterior of the car as it is possible to have. And
it is from this that are taken all the measurements used to specify
the tools that will make it when production starts.
Designing this way results not simply in a better built product, it
is also likely to be safer . Bentley's advanced Dynamic Crash Analysis
(DCA) capability means much of the trial and error traditionally associated
with providing a car with good impact resistance has been bypassed.
Nevertheless it should be understood that DCA, as with all virtual
design work will never replace real world test procedure, nor was
it ever designed to. Its role is simply to ensure that by the time
these tests are conducted, the product is in as good shape as possible
to meet each new challenge.
Powertrain
Even before it had been determined how the Continental GT would be
powered, two crucial decisions were made. First, the Continental GT
would possess a new level of performance that placed it among the
fastest road cars on earth; secondly that performance would remain
inimitably Bentley. Reconciling these issues would require a great
deal of power, but more importantly, huge torque delivered evenly
across the rev-range.
But if the car's packaging requirements were to be met the engine
couldn't take up much space under the bonnet and this is where you
discover that the secret of the Continental GT's interior room is,
in fact, its under the bonnet. By choosing the basic architecture
of the W12 powerplant used elsewhere in the VW Group, Bentley's engineers
were provided not simply with the opportunity to develop it into a
unique Bentley engine, but also to exploit its phenomenal packaging
attributes.
Instead of using two long banks of six cylinders, the W12 staggers
the cylinders in each bank creating effectively two extraordinarily
narrow angle (15deg) V6 engines sharing a common crankshaft and giving
rise to the 'W' formation.
This naturally provides a phenomenally short engine for its capacity,
and frees space that can be reapportioned to the car's interior. Indeed
it is the most compact twelve cylinder engine on the market is even
more compact than some V8s.
Once the decision to use the W12 had been made, it was necessary to
change entirely its specification to adapt it for the Continental
GT.
Two KKK turbochargers were carefully integrated into the under-bonnet
package. At the same time, Bentley's engineering team modified the
internal componentry of the powerplant until all its power, torque,
emissions, consumption and durability targets had been met or exceeded.
When they were done, the result was a car with 552bhp (560PS/411kW)
at 6100rpm. But power is nothing without the torque to back it and
this has been achieved not simply by providing 650Nm (479lb ft) of
torque but by making it available at just 1600rpm, a speed at which
most engines are little more than idling and stays that high up to
6000rpm.
All wheel drive power directed to all four corners
Having created one of the world's most powerful and responsive engines,
it was clear that an equally extraordinary transmission would be needed
to cope with it.
The use of all-wheel drive was decided in the earliest stages of the
project as it was felt that this new level of power demanded a commensurate
level of control. Besides, if the Continental GT was to be exploited
by its owners to its maximum potential, it would need to be at home
in all environments from the Santa Monica Boulevard to the compacted
snow surfaces of Alpine resorts.
Nevertheless, in order to ensure that the right Bentley feel is provided,
Bentley's powertrain and chassis engineers have experimented extensively
with the distribution of torque to the front and rear axles. This
has been done to provide the Continental GT with all the security
of a all-wheel drive system but when appropriate, the added fun factor
inherent within a rear-wheel drive layout.
Gearbox: six speed auto - the most advanced of its type in the world
Providing the link between the driven wheels and the engine is a six-speed
automatic transmission built for Bentley by ZF and the first of its
type to be used in an ultra-high performance coupé. The defining
characteristic of this transmission is its ability to lock its torque
converter in normal driving, providing the same immediacy of response
expected of manual transmissions. Despite this, shift quality is so
good that often the most obvious evidence of a gearchange having taken
place is the repositioning of the rev-counter needle or centre dash
gear display.
Tiptronic actuation means that the car can be used either as a conventional
automatic or as a clutchless manual where gear changes take place
only on command from the driver, via either the gear lever or paddles
mounted behind the steering wheel.
It is a fair observation that a 6-litre, twin-turbo engine does not
strictly need six gears. Then again, to look at any element of Bentley
performance in terms of need is perhaps to miss some of the point
of the marque. It's true that many Continental GT drivers will spend
much of their time allowing the transmission to shift itself, however,
Bentley also knows that most of its customers will be enthusiasts
who will relish the prospect of flicking up and down the gearbox at
the pull of a paddle or the push of a lever. Under the circumstances,
six speeds seem entirely appropriate.
Chassis: a car for drivers and passengers alike
Perfecting ride and handling is one of the most complex and difficult
areas of car design. For the Continental GT designers this job has
been doubly tough, for few cars have been brought to market with a
greater expectation of excellence in both areas.
Even so, by starting with well defined and ambitious targets and applying
clear thinking and the skills of a 25-strong chassis engineering team
to realise them, the Continental GT has been equipped with a chassis
that should appeal to sybarites and thrill-seekers equally. The result
is a car with firm rather than harsh suspension, impressive resistance
to roll, pitch and heave yet compliant enough to ride poorly surfaced
roads with absolute equanimity.
The basis of the Continental GT's chassis strategy is an extremely
stiff body, without which, even the most sophisticated of suspension
systems can be undermined. To this was applied the latest in suspension
technology featuring an innovative double wishbone arrangement at
the front - designed to minimise torque reactions through the steered
wheels - and a multi-link rear axle behind. Extensive use of aluminium
has been made to lower unsprung mass while the entire front subframe
of the car is fashioned from stainless steel. Air springs are used
at each corner, each one containing its own infinitely adjustable
electronic damper.
These electronic dampers do more than offer a few different settings
for the driver to play with. Within their set parameters they are
capable of adjusting themselves continuously without the driver ever
being aware of it.
Electronic stability systems: Unintrusive and at
the discretion of the driver
Naturally both traction control and the latest Bosch Electronic Stability
Programme (ESP) are fitted, though they can be disabled at the discretion
of the driver - Bentley has no desire to dictate how the Continental
GT is driven. The secret to understanding their function is to see
them as additional to the Continental GT's dynamic behaviour, rather
than as an essential ingredient in keeping a car of these capabilities
safe.
The Continental GT is capable of monitoring a whole range of dynamic
attitudes such as lateral acceleration, individual wheel speeds, throttle
position and brake pressure. No car can defy the laws of physics and
there are certain extreme conditions that even ESP will be unable
to guard against, but as an extra line of defence for the unfortunate
driver caught out by unexpected circumstances, its safety value is
real and evident.
Safety: prevention is even better than cure
Naturally the Continental GT is equipped with the full suite of passive
safety equipment. As well as possessing exceptional front, side and
rear deformation characteristics on impact, there are two front airbags,
four side airbags and two side curtain bags that, unusually for a
coupé, run along the full length of the cabin. Seat belt pretensioners
are used for all four seats.
Of course avoiding the accident in the first place has always to be
preferable. To this end the Continental GT is specified like few others
in the market. All-wheel drive, when correctly exploited, has colossal
safety advantages in adverse conditions, while the latest traction,
stability and brake control systems offer further opportunities for
drivers to extricate themselves from danger. And of course there is
the powerful engine and its ability to keep time spent on the wrong
side of the road during overtaking to an absolute minimum; and should
you ever have to accelerate away from trouble, few will do so more
quickly than this.
Progressive but utterly faithful to its heritage
In all physical senses, the changes the Continental GT has brought
to Bentley have transformed the company beyond recognition. The car
itself and the renewed factory in which it is being built mark the
dawn of a new and thrilling era for the marque.
But in a less tangible but no less important way Bentley is actually
returning to its heartland values, as defined by the founding vision
of WO Bentley. The strength of any brand in this sector is the thought
that created it, and while there were times in the distant past when
that vision had become little more than a nostalgic fairytale, now
and increasingly it resonates through the walls of the Crewe factory.
WO's proposition is as compelling today as it was 84 years ago. He
would combine cutting edge design with outrageous performance and
superlative craftsmanship to create a potent and unique motoring experience.
Moreover it would have a purpose that took it beyond mere recreation
and turned it into something of real use and significance.
And while it would offer great comfort and unquestioned luxury as
it went about its daily business, so also it would possess a thinly
veiled ability to turn into something very special at any moment.
He also understood that a good car will always be greater than the
sum of its parts. A car may look mightily impressive on paper, but
it all still has to gel on the road to create an authentic Bentley
experience, one that makes the driver feel in his or her element whatever
the conditions.
A true Bentley is a car that goes beyond satisfying the needs of its
customers: it should exceed all expectation and do so routinely; it
should possess an ambience beyond mere description, one that has to
be experienced before it can be appreciated. Above all it should blend
apparently conflicting interests as if they were made for each other,
proving thrilling yet cosseting, imposing but subtle, a car with great
presence but lacking entirely in ostentation. These are precisely
the qualities the Continental GT - a true British Grand Tourer - has
been styled, engineered and designed to provide and the result is
a car of which WO Bentley would be justifiably proud.
