2007 MODEL YEAR BENTLEY ARNAGE
Bentley Motors continues the intensive development of its flagship Arnage range
with the introduction of a major programme of powertrain and chassis
enhancements for the 2007 Model Year. The Arnage's renowned 6.75-litre V8
engine now develops up to 500bhp and is mated to a six-speed automatic
transmission benefiting performance, driving dynamics and refinement. The
powertrain changes are complemented by subtle exterior, interior and
under-bonnet design cues.
Key to this performance increase is the most powerful version of Bentley's
legendary V8 engine ever built at the company's headquarters in Crewe, England.
In the performance-oriented Arnage T model, the revised twin-turbocharged V8
engine produces a staggering 500bhp and 1000Nm of torque - an 11percent
increase in power and a 14 percent increase in torque over the outgoing model.
Twinned with the latest six-speed ZF automatic transmission, which uses
state-of-the-art computer management, performance and refinement are optimised
at all speeds. In the Arnage R and RL models the new engine is boosted from 400
to 450bhp, while torque climbs from 835 to 875Nm.
"The 2007 Model Year Arnage range is clear evidence of our intent to ensure
Bentley's flagship model remains at the forefront of technology and delivers
the performance, refinement and luxury that every Bentley customer demands,"
explains Stuart McCullough, Member of the Board, Sales and Marketing.
The 500bhp Arnage T is a true driver's car with much higher performance and
delivers an even more rewarding driving experience. The improvements to the
refinement and comfort of the 450bhp Arnage R are equally striking, while the
long-wheelbase RL shares the same increased power output together with major
improvements to the rear passenger cabin.
"Two years ago we introduced major upgrades to the Arnage's chassis, steering
and brakes," says Dr Ulrich Eichhorn, Member of the Board, Engineering. "Those
improvements meant the car could easily handle a significant increase in power
and torque, so work began on this important powertrain programme."
The 2007 Model Year Arnage also benefits from safety, interior and design
improvements. Every Arnage now has a Tyre Pressure Monitoring System, rSAP
Bluetooth integrated telephone system and improved driver ergonomics as
standard. Additionally, new wheel, exterior paint colour and interior trim
options are available, as well as an optional retractable 'Flying B' bonnet

Bentley's 6.75-litre V8 engine is the centrepiece of the 2007 Model Year Arnage
development programme. This remarkable engine, the fundamental design of which
has served Bentley models proudly for nearly five decades, has been extensively
re-engineered to provide, in Arnage T specification, 500bhp and 1000Nm of torque
- figures that ensure that the legendary Bentley wave of torque is even more
astonishing than before. Top speed of the Arnage T has risen from
168mph/270km/h to 179mph/288km/h, while the 450bhp Arnage R and RL's maximum
speed increases by 13mph/21km/h to 168mph/270km/h.
When the first V8 engine was built in the1950s, the design brief unwittingly
benefited later generations of Bentley engineers. It was a very forward
thinking design with an all-aluminium construction, a five main-bearing
crankshaft, and a well-supported camshaft. The steps taken then laid the
foundations for the longevity of the engine.
"People might raise an eyebrow when they are told that the V8 engine in their
2007 Model Year Arnage was first used by Bentley in 1959," says Bentley Motors'
Director, Powertrain and Chassis, Brian Gush. "But the reality is the basic
design was so good that we have been able to continually improve it for nearly
"One of the reasons the engine has evolved so successfully is the position of
the exhaust valves, high in the cylinder head, originally designed for rapid
heat dissipation to help engine cooling. Decades later it meant that we could
heat the catalytic converter due to the short path from valves to catalysts,
which benefits exhaust emissions. This is just one of the reasons why this
brilliant engine lives on today."
That first 6.25-litre engine produced around 200 horsepower - the new 2007
Model Year 6.75-litre V8 has more than twice that output, with 500bhp and
1000Nm of torque for the Arnage T. It was the introduction of turbocharging and
intercooling in the early 1980s that saw step-change increases in the V8's
performance, and the latest engine programme is no different. Two new
low-inertia turbochargers operate with far greater efficiency at lower engine
speeds - they reach maximum turbine speed in half the time of the previous unit
- thereby ensuring significantly reduced turbo lag and that prodigious wave of
torque at any revs.
Furthermore, a reprofiled camshaft with an all-new roller tappet system
provides revised valve timing and substantially improved refinement. These
changes also deliver for increased power, enhanced durability and ensure
compliance with European EU IV and US LEV II standards. Although the 2007MY
6.75-litre engine produces around 300 horsepower more than its 1959
predecessor, its fuel consumption is only 60 percent of the original and thanks
to its advanced fuel injection and exhaust controls, its emissions output is an
incredible 99 percent lower than Bentley's first V8.
Drivetrain & Chassis
Such an impressive increase in power and torque is, however, of little benefit
unless the powertrain is capable of delivering it to the driven wheels. For
this reason Bentley's engineering team opted to introduce the latest six-speed
ZF automatic transmission to the Arnage range. This state-of-the-art system
offers two further ratios than the previous gearbox and has several key
advantages over its predecessor:
- The wider range of ratios is specifically tuned to each Arnage model,
ensuring greater flexibility, response and refinement for every model.
- Performance feel is also improved by using a sophisticated locking torque
converter system which provides a more rapid response to throttle inputs.
- Three transmission modes (Drive, Sport and Semi-Automatic) allow the driver
to take full advantage of the new gearbox. Semi-Automatic mode is accessed by
placing the gearlever into the sequential manual gear-selector gate, where a
new ratio can be engaged simply by pushing the lever forwards or backwards.
A sophisticated electronic management system plays a major role in providing
fast yet smooth gearshifts regardless of how the car is being driven.
Previously the Arnage's engine and transmission were governed by independent
electronic systems; in the 2007 Model Year, an uprated Bosch
computer-controlled management system ensures that both parts work as a single
unit to produce a supremely refined yet highly responsive drivetrain.
"The new ZF gearbox gives us a different dimension in transmission control,"
says Dr Ulrich Eichhorn, Member of the Board, Engineering. "Our main objective
was to get the engine and transmission working together enabling us to transmit
every ounce of power. Using the lock-up in all gears eliminates what we call the
'rubber-band' effect - the surge of engine speed without a corresponding
acceleration of the car - and gives much more immediate connection of throttle
input to road speed.
"As the engine speed approaches the point at which a gearshift is due, it
signals to the transmission that it is time to shift, so the ratio changes are
much quicker - it feels significantly faster from the driver's seat. Similarly,
when the gearbox is ready to change up it asks the engine to reduce the torque
just for the period of the shift, which adds to the refinement."
Another important development for the 2007 Model Year Arnage range is the
separation of the sports suspension and sports gearbox settings, allowing the
driver to select their preference for each system independently - via a 'Sport'
button on the dashboard for the suspension and by positioning the gearlever for
the transmission's Sport mode.
A comprehensive chassis tuning programme was instigated alongside the
powertrain updates to ensure the Arnage's chassis comfortably handles the
additional performance. Refinements to the ESP logic system allow more spirited
handling without any reduction in stability or safety.
The Traction Control system is extensively recalibrated with the aim of
avoiding unnecessary reduction in engine torque. The ESP system now monitors
the car's overall stability rather than simply loss of grip to the wheels. This
reduces the amount of intervention required and restores power earlier and more
progressively, allowing the power of the engine to be fully exploited.
"We don't believe in creating power and then taking it away," says Brian Gush,
Director, Powertrain and Chassis. "This new system allows the driver a lot more
freedom to feel where the traction limit is without ever getting into trouble.
The traction control is much more progressive and proportional - you can drift
the car with some wheelspin but it never lets you get in any trouble. It is a
calibration which keeps the spirited driver in mind."
Following the detailed design updates made to the 2005 Model Year Arnage, the
latest models receive further exterior styling changes.
'The revisions we made to the Arnage series two years ago gave the range
exactly the sort of contemporary yet authentic Bentley feel that it needed,"
says Head of Exterior Design, Raul Pires. "Now with big increases in power and
performance we wanted to add some subtle design cues to reflect the differences
between the Arnage models."
The performance intent of the Arnage T is underlined by the addition of a new
dark finish to its front radiator and bumper grilles. A standardised bright
chrome finish is applied to the R and RL grilles while Bentley 'B' badges have
been applied to the D-pillars on all models.
To highlight the superb feat of engineering beneath the Arnage's bonnet, a
newly styled engine bay leaves no doubt as to the potency of the car. A black
crackle finish has been applied to the Arnage T's inlet manifold, while every
model displays an embossed Bentley logo on the turbocharger plenum chambers and
new '63/4 LITRE TWIN TURBO' engine plaques.
Additional optional extras include a 19-inch six-spoke disc wheel for the R and
RL models, and 19-inch five-spoke 'Blade' sports wheel for the Arnage T. Also
available across the range is the famous winged 'B' mascot, which saw a welcome
return this year on the Diamond Series Arnage. The iconic mascot - which can
retract neatly into the grille surround - was originally designed by motoring
artist F. Gordon Crosby and first used on the 1930 Bentley 8 Litre.
Interior design updates include a new hide-trimmed gearlever, chrome gearlever
bezel, and new Thin Film Technology driver information panel to display more
comprehensive and clearly accessible information. The Arnage RL model receives
additional standard specification including a rear centre armrest bottle
cooler, veneered rear centre cushion box, rear rSAP Bluetooth master telephone
system and reversing camera (US, EU, Australia and New Zealand markets only).
The significant upgrades to both engine and transmission mean every new Arnage
will not just match customer expectations but surpass them on all fronts, as Dr
Franz-Josef Paefgen, Bentley Motors' Chairman and Chief Executive explains:
"These important powertrain enhancements reaffirm the very essence of the
Bentley Arnage, offering our customers an absolutely unique blend of seamless
power and torque which produces storming performance when you demand it and
blissfully relaxed cruising when you don't."
