(from BMW Press
Release) The announcement of a new M car remains a rare
and exciting occasion, and the launch of the new M6 in 2005 will
reveal a potent new combination of BMW engineering and M power.
Hot on the heels of the new M5, and taking lightweight design
solutions from the M3 CSL, the new M6 combines supercar presence
with Grand Touring potential. Joining an exclusive club, the fourth
new M car of the decade sets a new performance benchmark for a
production car. The beauty of the M6 is also its ability to
comfortably crush kilometres on a cross-country cruise.
The BMW M6 is the new standard-bearer for BMW’s M car range, as well
as the return of a much loved and highly regarded BMW badge. The
latest M car features:
5.0-litre V10 engine
panels including carbon fibre roof
0 – 62mph in 4.6
seconds / 62 – 0 in 36 metres
155mph limited top
Like its predecessor -
the legendary 1985 M635CSi – the new M6 resets the sports GT
benchmark, with supercar performance, dispatching the zero to 62mph
sprint in 4.6 seconds and achieving a limited top speed of 155mph.
If derestricted, the M6 would be capable of a 200mph+ top speed.
During tests at the famous Nürburgring Nordschleife circuit, the new
M6 regularly clocked eight minutes lap times. These rarefied
performance statistics are, however, backed up by ‘real world’
economy and efficiency - the new M6 delivers a combined EU fuel
consumption of 19.0mpg and a CO2 rating of 357g/km.
Powered by the same 4,999cc engine that set new standards in the M5,
the 507bhp power output ensures that the new M6 maintains the M car
tradition of breaking the 100bhp per litre benchmark. Peak power is
developed at 7,750rpm with the red line set at 8,250rpm. Peak torque
of 520Nm is developed at 6,100rpm of which 450Nm is available from
just 3,500rpm. The 90-degree V10 aluminium-silicon alloy engine
block is extremely light yet robust and is the first V-arrangement
engine to use a bedplate construction. The aluminium bedplate with
cast-iron inlays ensures the engine’s rigidity throughout the rev
range, but the complete unit still weighs just 240kg.
The capable chassis of the new M6 permits lateral acceleration in
excess of 1g. To cope with such forces, the V10 engine features a
lateral force-controlled oil supply that, from 0.6g of lateral
movement, activates one of two electronic oil pumps to draw oil from
the cylinder head and delivers it back into the sump to ensure
perfect lubrication even in the most extreme situations. It is
because of the extreme forces that can be induced by the M6 that the
car also makes use of a semi dry sump lubrication system with an oil
reservoir on each side of the front subframe.
Masterminding all the M6’s engine electronics is one of the most
advanced engine control systems ever developed. The MS S65 control
unit coordinates all engine functions using three 32-bit processors
that handle more than 200 million operations per second from over 50
incoming signals. Each of the 10 cylinders has its own throttle
butterfly, with its position being monitored 200 times per second.
Reacting to changes in throttle position, the butterfly can move
from closed to fully open in a mere 120 milliseconds (approximately
three times faster than the blink of an eye).
Like the M5, the new M6 also uses BMW’s new third-generation seven
speed Sequential Manual Gearbox (SMG) with Drivelogic. Drivelogic
offers the choice of 11 different change patterns, depending on the
speed of change required. Six change patterns are available in the
manual mode and five in the ‘automatic’ mode, in which the gearbox
will automatically select the most appropriate gear depending on
The new SMG gearbox also offers safety benefits when downshifting on
slippery surfaces. If it detects the rear wheels locking up, the
clutch opens for a fraction of a second to ensure traction is
maintained. Hill Detection is another SMG feature. In automatic
mode, the SMG gearbox recognises that the car is travelling on an
incline and holds gears uphill to maintain acceleration and selects
lower gears when progressing downhill to make the most of the
available engine braking.
The suspension of the new M6 is based on the ‘standard’ 645Ci
geometry. With the exception of components such as tie bars, wheel
mounts and bearings, the double-arm spring strut front axle is made
completely of aluminium. The U-shaped front subframe houses the rack
and pinion steering assembly, anti-roll bar and track control arms.
The Integral IV rear axle assembly is also made from aluminium to
reduce unsprung masses. In addition, the new M6 features BMW’s
variable, speed-sensing M Differential Lock. Featured on all current
BMW M models, the M Differential Lock builds up locking action
whenever one of the rear wheels begins to spin, channelling drive to
the wheel with the most grip to improve handling and stability.
Electronic Damper Control is also standard on the M6. Offering the
driver three suspension settings – Comfort, Normal and Sport,
drivers can select the most appropriate setting for their driving
style or road conditions. The new BMW M6 also features a BMW M
version of Servotronic steering with two specific settings
corresponding to the Electronic Damper Control settings, Sport or
BMW’s DSC stability control system has been adapted for the M6.
Featuring M Dynamic Mode (first seen on the new M5), drivers can
take their cars to the limit of the laws of physics, allowing
considerable angles of controllable oversteer when circumstances
The new BMW M6 comes with a Power button (pioneered in the M5) in
the centre console. Initially the car pre-selects the P400 setting,
delivering 400bhp for town or city driving, for example. Engaging
the Power button modifies the response of the throttle and enables
the P500 setting to deliver the full 507bhp generated by the V10
Control of all of these features has been brought together using the
M6’s MDrive Manager. MDrive allows the driver to pre-select specific
settings for the Power button, SMG gearbox, DSC, EDC and Head-up
Display. With one push of the steering wheel-mounted button, the
driver selects his or her chosen character. For example, the car can
be set up for an exciting 30 mile A-road drive to and from work or,
on the other hand, for a city commute. More extreme settings can be
pre-programmed for track use.
For a car with such potential, high performance brakes are needed
and the new BMW M6 doesn’t disappoint. Using aluminium double piston
callipers and cross-drilled disc brakes, the car can stop from 62mph
in just 36 metres and from 124mph (200km/h) in only 140 metres –
equivalent to 1.3g deceleration.
Specially developed tyres ensure that the prodigious horsepower and
braking power are transferred to the road. Measuring 255/40ZR19 on
the front and 285/35ZR19 on the rear, the tyres are mounted on
lightweight five-spoke 19-inch forged aluminium wheels, each
weighing 1.8kg less than a normal cast alloy wheel.
Like other 6 Series models, the new BMW M6 uses a hybrid
construction of aluminium, thermoplastics and SMC (Sheet Moulding
Compound). This mixture of materials delivers an extremely rigid,
yet light, body structure. The front wings are made of
thermoplastics, the doors and bonnet of aluminium and the boot lid,
SMC. Like the legendary M3 CSL, but unlike the 630i and 645Ci, the
new BMW M6 also uses carbon fibre in the construction of the roof
panel to reduce the weight yet further – this feature alone saves
nearly 5kg and contributes towards the overall weight of just
Visually, the new M6 differentiates itself from the 6 Series by a
deeper front valance with air intakes for the engine and brakes,
more contoured sills and rear valance that includes a diffuser to
increase aerodynamic efficiency. Nestling under the rear valance are
BMW M’s telltale four rear exhaust pipes. To complement the changes
in body styling, the new M6 is available in four exclusive M colours
– Indianapolis Red, Sepang Bronze, Interlagos Blue and Silverstone
alongside three other 6 Series colours.
Inside, the new M6 comes with fully adjustable M sports seats that
include lumbar support and an adjustable backrest width as standard.
They are covered in extended Merino leather, with the owner able to
choose between Black, Silverstone or Sepang. As an option, full
Merino leather can be specified in Indianapolis Red and Portland
Natural Brown alongside the other three colours that includes a
leather covered dashboard and Alcantara headlining.
The new BMW M6 also features BMW M’s version of the new Head-up
Display system. Unlike the standard Head-up Display available on 5
and 6 Series models that offers navigation instructions and cruise
control information, the system on the M6 projects driver-focussed
information such as engine speed, gear selected and road speed
directly into the driver’s view, obviating the need for the driver
to take his or her eyes off the road ahead.
The new M6 will go on sale towards the end of 2005. Dates and prices
will be announced in due course.
