The BMW M4 GTS gives BMW M GmbH a new and exclusive
technological showpiece which elevates the potential of the BMW M4 Coupe to
another impressive new level. With its powerful, motor sport-inspired looks and
highperformance technology, the BMW M4 GTS has its sights set squarely on the
race track. A lap time of 7.28 minutes around the legendary Nürburgring-
Nordschleife, the world's most exacting race circuit, is a clear statement of
this special-edition model's exceptional abilities. At the same time, the
sharpest BMW M4 of all - like its BMW M stablemates - can also hold its own on
public roads. BMW M GmbH is launching the BMW M4 GTS in a special edition
limited to 700 units to celebrate the 30th anniversary of the BMW M3, which has
been in production since 1986. In so doing, it is highlighting the innovative
flair of the BMW M engineers in developing trailblazing M technologies on the
powertrain, chassis and lightweight construction front. The first
highperformance special edition in the M3/M4 model range will also be available
for the first time in the important North American market.
"Special-edition models like the BMW M3 GT, BMW
M3 CSL, BMW M3 GTS and BMW M3 CRT have a decades-long tradition in our mid-size
line-up - and that continues with the BMW M4," says Frank van Meel, CEO of
BMW M GmbH. "They sharpen the character of the BMW M brand and embody an
emotionally rich and exclusive driving experience. We've taken a radical route
with the set-up of the BMW M4 GTS to create a sports machine for the race track
that delivers top-end dynamics and inspirational performance. It allows us to
demonstrate what is possible today with a road-legal car. Owners can drive
their BMW M4 GTS to circuits such as Spa-Francorchamps, the Nürburgring or
Laguna Seca - for clubsport events, for example - and then set lap times there
that raise the bar to extremely high levels for road-legal cars."
Performance boost courtesy of innovative water
injection
At the heart of each and every BMW M model is its
engine. The BMW M4 GTS uses the multi-award-winning six-cylinder in-line turbo
engine from the BMW M3/M4, but adds innovative water injection technology to
give the 3.0-litre unit a substantial power boost. The water injection system
raises the engine's output significantly - to 368 kW/500 hp - and increases
torque to 600 Nm (442 lb-ft), yet still keeps fuel economy and CO2 emissions at
the level of the BMW M4 Coupe (8.3 litres per 100 km [34 mpg imp], 194 g/km).
This makes the BMW M4 GTS the most agile, radical and dynamically potent model
in the range. It races from a standstill to 100 km/h (62 mph) in a mere 3.8
seconds and hits a limited top speed of 305 km/h (189.5 mph).
Intelligent lightweight construction allows the BMW M
engineers to limit the car's DIN kerb weight to 1,510 kilograms (ECE kerb
weight: 1,585 kg). Its outstanding weight-to-power ratio of 3.0 kg/hp provides
the perfect platform for a highly dynamic driving experience. The rigorous
weight-saving measures extend through both the interior and exterior of the
car. Inside, carbon-fibre bucket seats, a lightweight centre console, the
lightweight construction of the rear seat panelling and boot area partition,
and special lightweight door and side panel trim, including door pull loops in
place of solid door handles, are clearly visible indications of the designers'
commitment to weight-saving. The rigorous application of lightweight design can
also be seen in details that are out of view.
The instrument panel bracing tube
is made from lightweight carbon fibre. And on the outside of the car, the newly
designed bonnet, roof and adjustable front splitter are also constructed from
carbon-fibre-reinforced plastic (CFRP). The adjustable rear wing, too, is cut
from this light but extremely durable high-tech material. It rests on
intricate, CNC-machined aluminium mounts fixed to the CFRP boot lid which
likewise demonstrate how every detail, no matter how small, has been honed to
minimise weight. Teaming up with the diffuser - again, made from carbon fibre -
below the rear bumper, the rear wing optimises the flow of air and reduces lift
at the rear axle. The exhaust system has a titanium muffler, which allows a weight
saving of 20 per cent. Its emotionally rich soundtrack fits the M profile
perfectly and envelops the inside and outside of the car in the ambience of the
race track.
Performance-maximising equipment features
The standard-fitted seven-speed M Double Clutch
Transmission (M DCT) selects the optimum ratio for every driving situation with
no interruption in the flow of power as it makes its way to the rear wheels.
The driver can also select gears manually using either shift paddles on the
steering wheel or the selector lever. The Drivelogic shift programs and Launch
Control have been retuned to the engine's increased output. The
weight-minimised, exclusive M light-alloy wheels in star-spoke 666 M Styling
are forged and polished, and come in Acid Orange. They are fitted with Michelin
Pilot Sport Cup 2 tyres (front: 265/35 R19, rear: 285/30 R20) which are adapted
specifically to the BMW M4 GTS and therefore play a role in the car's
outstanding mechanical traction and feedback through corners.
The three-way M coilover suspension specially tuned
for the BMW M4 GTS can be adjusted to individual tastes and therefore also to
the demands of different race circuits. The lightweight M carbon ceramic brakes
offer a welldefined pressure point and ensure outstanding deceleration even
under sustained heavy loads, such as at the limit on the race track.
World-exclusive OLED technology, brilliant LED light
The familiar two sets of twin circular headlights with
four corona rings ensure the best possible illumination of the road surface.
They combine cutting-edge LED (light-emitting diode) technology with BMW
Selective Beam (dazzle-free high beam assistant) and Adaptive Headlights.
The L-shaped rear lights are just as distinctive as
the design of the headlights. Indeed, innovative OLED rear lights will make
their series-production debut in the BMW M4 GTS. OLEDs (organic light-emitting
diodes) are a new kind of light source that light up over their full surface
with a very homogeneous effect - unlike LED units, which emit their light in
the form of points. The flat design of OLEDs (they measure just 1.4 millimetres
in height) and the ability to trigger individual light modules separately open
up fresh possibilities for lighting concepts and exudes the presence of
exceptional precision. As such, the tail lights underline the width of the rear
end, lend the car an even more eye-catching and powerful appearance and ensure
it cuts a stand-out figure in both the light and dark.
The interior - focused, exclusive and committed to
motor sport
The carbon-fibre M bucket seats for the driver and
passenger stick firmly with the lightweight construction theme inside the
pure-bred, exclusive interior. They weigh around 50 per cent less than the
sports seats in the BMW M4 Coupe, enable an ideal seating position and offer
compelling longdistance comfort to go with their unbeatable levels of support.
The exclusive Alcantara/Merino leather seat covering along with M stripes in
the backrests, three-point seat belts and door pull loops highlight the profile
of the BMW M4 GTS as a high-performance sports machine as well as the car's
standalone character. The M4 GTS is fitted with different bucket-style M sports
seats (including lightweight backrests with cut-outs) for the North American
market, in line with local registration requirements.
The exclusive material Alcantara is also used for the
M sports steering wheel, whose "12 o'clock" marker underlines the
racing character of the BMW M4 GTS. In place of a rear seat bench, the BMW M4
GTS features a glass-fibre-reinforced plastic (GFRP) shelf and a rear panel in
carbon-fibre sandwich construction. Both are covered in Alcantara, and together
they enable a weight saving of around 40 per cent.
The optional Clubsport Package can further enhance the
affinity of the BMW M4 GTS with the race track. It includes a roll bar in Acid
Orange behind the front seats, a race-specification six-point harness and a
fire extinguisher.
Intelligent lightweight design across the board
Intelligent lightweight engineering, already a vital
consideration for the BMW M4, has been taken to new and even more
uncompromising levels on the BMW M4 GTS. The goal was to minimise kerb weight
in order to give the new model outstanding driving dynamics, top-class agility
and highest efficiency. Rigorous lightweighting extends to even the smallest
details of the BMW M4 GTS, delivering a DIN kerb weight of 1,510 kilograms (ECE
kerb weight: 1,585 kg).
The low weight of the BMW M4 GTS improves not only
performance but also dynamics and handling. Drivers perceive the benefits in
the form of even more responsive steering, more precise cornering, shorter
stopping distances and new levels of control when pushing the vehicle to its
limits.
