Now to say any motor car is a ‘bargain’
when its retail price in this country is around 20 million
baht, sounds ludicrous, but read further. You have to compare
like with like. This is a luxury motor car and has to be
compared with other luxury motor vehicles. You have also to
take into consideration that this is the fastest four seat
production car in the world.
Bentley
Continental GT
I had a good look at the example at the
Bangkok International Motor Show, thanks to Greg
Pluegboonyachai, the general manager of Bentley Thailand, and
it is simply stunning. Photographs do not do this car justice.
In the metal it is breathtaking.
Open the door and it is even better! The
show car had a light tan leather upholstery and I joking
suggested that it must have resulted in the slaughter of a
herd of cows. “Only seven,” said Greg, with a straight
face.
Here
are some brief specifications. Up front is the twin turbo,
6-litre, W12 engine developing 552 bhp and 650 Nm of torque.
Maximum torque developed at just 1600rpm. That’s barely off
idle revs! Top speed of 198mph (318 kph) and 0-100 km/h in 4.8
sec. Six speed, paddle operation automatic transmission with
full lock-up and four-wheel drive with central Torsen
differential, computer controlled air-sprung multi-link
suspension front and rear and the largest brakes of any car
ever put into production.
Let’s look at some specifics, for the
technically minded readers. The powerplant of the Continental
GT is its 5998cc, four camshaft, 48-valve, twin turbocharged
W12 engine. 552 bhp (411kW) at 6100rpm. Maximum torque is 650
Nm (479lb ft) which may sound impressive but what is doubly
impressive is that it is generated at just 1600 rpm.
This
engine is a technological tour de force. It is physically the
smallest 12 cylinder engine currently in production, despite
its 6 litre displacement. This has been made possible by its
‘W’ formation where instead of arranging the cylinders in
two long rows as you would in a conventional V12
configuration, each bank of cylinders is actually staggered,
effectively creating two V6 engines on a common crankshaft.
The angle between the two main banks is 72 degrees, and
between the staggered cylinders just 15 degrees.
The transmission is something special too.
The ZF 6HP26 gearbox is the most advanced of its kind in the
world, offering not only six ratios but also the ability to
lock up its torque converter in every gear, effectively
providing manual gear changes via either the gear lever or
steering wheel paddles.
To get all the grunt to the ground, the
Bentley Continental GT has All Wheel Drive (AWD). The system
used employs a central Torsen (TORque SENsing) differential
and a free (open) differential for the front and the rear.
Both the front and centre differentials have individual
cooling radiators. The drive is split equally between the
front and rear, giving a conventional 50:50 torque split, but
is infinitely variable according to available grip and the
Torsen differential, together with the 4 wheel sensors can
detect slip of less than one percent and act accordingly,
sending the engine’s torque to either the front or rear
axle.
Interestingly, the Bentley gets away
without a limited slip differential at the front and the rear,
by the use of modern electronics. When slip is detected at one
wheel, the electronic system can apply the brakes individually
to that wheel and allow the torque to be transferred across
the car to the tyre with the most grip. In normal use this
system acts quite seamlessly, without the driver being aware
of what is happening but it does keep the Continental GT
moving forward when traction is available to just one of its
four wheels. So if you are planning on spending a holiday in
the Swiss Alps, this is the car for you! (Yes, it a large boot
and ski-friendly through-loading facility.)
This is a car of the future, as far as
electronics is concerned. Consider these points: Each
Continental GT contains approximately 3.2 km of cabling and
the main wiring harness alone weighs over 50 kg. A Continental
GT also contains 70 microprocessors (your computer has only
one)! It has 35 individual control units - black boxes by
another name - and they all talk to one another via three
Control Area Networks (CAN) working at 500 kilobits/sec, and
one superfast fibre-optic serial network operating at 4.2
megabits/sec. The computer buffs will understand more than I
do.
This electronic whizzbangery is important
because all the various features on the car need to know what
the others are up to as rarely does one have no impact on any
of the others. For example, if the windows are being lowered,
this is information that is likely to be of interest to the
security systems. Another example is the information provided
by the self-levelling sensors in the suspension is also of use
to systems such as the electronics constantly monitoring the
car’s progress and the automatic headlight levelling to keep
the beam at a constant height.
This car re-defines ‘Grand Touring’ and
is certainly one car that I would love to own. It has almost
everything I need.
If you have a spare 20 million baht, give Greg
Pluegboonyachai a call at 02 661 8800-1. If you buy one, tell
me too and I’ll go you halves in the ‘spotters’ fee!
