The powertrain concept for the new BMW M3 CS teams a 405 kW/550 hp
six-cylinder in-line engine with an eight-speed M Steptronic
transmission and the M xDrive intelligent all-wheel-drive system.
These combine to produce a 0 to 100 km/h (62 mph) time of 3.4 seconds
and supreme driving talents that can be enjoyed from each of its four
seats. The new BMW M3 CS will be built in a limited run at BMW Group
Plant Munich from March 2023, with its phased launch getting underway
the same month. The USA, Germany, the UK and Japan are the most
important sales regions for the new special-edition model.
More power, less weight, compelling performance.
A more power/less weight formula instils the new BMW M3 CS with
compelling performance qualities and an exclusive aura. It draws its
power from a specially upgraded version of the high-revving
six-cylinder in-line engine with M TwinPower Turbo technology
developed for the BMW M3 and BMW M4 models. This 3.0-litre unit also
forms the basis for the engine that powered the BMW M4 GT3 to the DTM
touring car title at the first time of asking in 2022.
The engine under the bonnet of the new BMW M3 CS therefore also
boasts a wealth of technological details derived directly from the
race-car unit. Its crankcase has a sleeve-free, closed-deck
construction and is extremely rigid, making it suitable for very high
combustion pressures. Weight-saving cylinder bores with a wire-arc
sprayed iron coating reduce frictional losses. The forged lightweight
crankshaft aids power build-up with its exceptionally high torsional
resistance while also feeding the engine’s high-revving instincts. Its
cylinder head has a 3D-printed core, allowing the coolant ducts to be
routed in an optimum arrangement for temperature management that would
be impossible to achieve using conventional metal casting methods. The
system of oil supply is designed to handle the specific challenges of
track use, as is the cooling system.
Straight-six engine produces 405 kW/550 hp.
These carefully tailored modifications reflect the unwavering focus
on achieving high rev speeds and maximum power delivery with the
engine in the new BMW M3 CS. The unit’s considerable upgrade potential
paved the way for a 30 kW/40 hp hike in peak output compared with the
BMW M3 Competition Sedan with M xDrive (fuel consumption combined:
10.1 – 10.0 l/100 km [28.0 – 28.2 mpg imp]; CO2 emissions
combined: 230 – 228 g/km in the WLTP cycle; figures for the NEDC
cycle: – ), resulting in 405 kW/550 hp. This increase in power was
achieved courtesy of targeted revisions to the engine’s M TwinPower
Turbo technology and required no concessions in terms of stability or
durability. The adjustments primarily involved raising the maximum
charge pressure of the two mono-scroll turbochargers from 1.7 to
2.1 bar and making some model-specific tweaks to the engine management.
In addition, a specially designed engine mounting with increased
spring rates creates an extremely rigid connection between the power
unit and the vehicle’s structure. A press of the accelerator is
therefore greeted by even sharper engine response and direct
transmission of its power to the drivetrain. The engine in the new
BMW M3 CS puts peak torque of 650 Nm (479 lb-ft) on tap from just
2,750 rpm and sustains it all the way to 5,950 rpm. It generates
maximum output at 6,250 rpm and tops out at 7,200 rpm.
The unit’s specific performance characteristics are dominated by its
unabated power delivery through to the upper echelons of the rev
range. This is accompanied by the emotionally stirring soundtrack
produced by the dual-branch exhaust system featuring electrically
controlled flaps, a titanium rear silencer with weight-minimising
design and – in customary M fashion – two pairs of tailpipes painted
in matt Black. Selecting the SPORT or SPORT+ modes for the engine
setting in the M Setup menu dials up the drive sound to produce a note
with unmissable racing car undertones. This injects real aural drama
into proceedings, particularly with gear changes and the accompanying
adjustments in rev speed.
Feeding standout power onto the road to optimum effect:
eight-speed M Steptronic transmission, M xDrive, Active M Differential.
The drive torque unleashed by the engine in the new BMW M3 CS is
relayed via an eight-speed M Steptronic transmission with Drivelogic.
This is operated using either the M-specific selector lever on the
centre console or the carbon-fibre shift paddles on the steering
wheel. The driver can use the Drivelogic button integrated into the
selector lever to alter the transmission’s shift characteristics, with
the choice of comfort-oriented, sporty and track-optimised settings.
The traction and agility of the new BMW M3 CS are both enhanced by
the presence of M xDrive all-wheel drive, which uses an electronically
controlled multi-plate clutch in the transfer case to ensure fully
variable and super-smooth distribution of the engine’s power between
the front and rear wheels. The multi-plate clutch’s oil supply has
been optimised to keep the all-wheel-drive system performing
effectively even under hard driving on the track. The system’s
rear-wheel bias and the way it teams up with the Active M Differential
at the rear axle – whose operation is also fully variable – add to the
signature M feeling when accelerating or powering through corners.
The M Setup menu lets the driver switch from the default 4WD setting
to 4WD Sport mode, which directs an even greater proportion of the
engine’s torque to the rear wheels. Drivers can also switch off the
DSC (Dynamic Stability Control) system altogether and engage 2WD mode.
By sending drive power solely to the rear wheels and suppressing any
intervention from the control systems to stabilise the vehicle, this
setting engages skilled drivers in the driving experience to an even
more intense degree.
The engine, transmission and M xDrive join forces to produce stunning
acceleration times. The new BMW M3 CS takes just 3.4 seconds to power
from 0 to 100 km/h (62 mph) and 11.1 seconds to reach 200 km/h
(124 mph) from rest. The midrange surge from 80 to 120 km/h (50 –
75 mph) is over in 2.6 seconds (in 4th gear) or 3.3 seconds (in 5th
gear). The BMW M3 CS comes with the M Driver’s Package as standard and
has an electronically limited top speed of 302 km/h (188 mph).
Bespoke tuning for chassis technology and the DSC system;
track tyres as standard.
The chassis technology in the new BMW M3 CS has been tuned precisely
to the engine’s performance characteristics, the overall vehicle
concept and its weight distribution. The model-specific settings for
the DSC system and M Dynamic Mode have also been purposefully geared
to the specific demands of high-speed circuit driving.
The individually tuned axle kinematics and bespoke wheel camber
settings, dampers, auxiliary springs and anti-roll bars serve to
optimise steering precision, transmission of lateral control forces
when cornering, spring and damping response and wheel location. The
electronically controlled dampers of the adaptive M suspension on the
new BMW M3 CS likewise come in a model-specific setup, as do its
electromechanical M Servotronic steering with variable ratio and its
integrated braking system.
Standard specification for the special-edition model includes
M Compound brakes with brake callipers painted in a choice of Red or
Black. There is also the option of M Carbon ceramic brakes whose brake
callipers are available in matt Gold or Red. Also on the standard
equipment list for the new BMW M3 CS are forged M light-alloy wheels
in an exclusive V-spoke design with a Gold Bronze finish. These
particular M light-alloy wheels can also be ordered in an optional
matt Black finish. Measuring 19 inches in diameter at the front axle
and 20 inches at the rear, the wheels are fitted as standard with
track tyres that have been purpose-developed for the special-edition
model and measure 275/35 ZR19 at the front and 285/30 ZR20 at the
rear. As an alternative to these tyres, which are specially designed
for circuit driving, customers also have the no-cost option of
high-performance tyres with the same dimensions.
Lightweight construction with extensive use of carbon fibre;
improved body rigidity.
Extensive, model-specific lightweight design measures play a major
part in moulding the performance qualities and exclusive character of
the new BMW M3 CS. The use of components made from carbon
fibre-reinforced plastic (CFRP) both inside and out is of key
importance here. Besides its carbon fibre roof, the special-edition
model also uses this lightweight, high-tech material for its bonnet,
front splitter, front air intakes, exterior mirror caps, rear diffuser
and rear spoiler. Its centre console, the shift paddles on the
steering wheel and its interior trim strips are likewise all
manufactured from CFRP. The standard M Carbon bucket seats also do
their bit to keep weight down in the cabin. The titanium rear
silencer, meanwhile, shaves more than 4 kilograms off the weight of
the exhaust system fitted on the new BMW M3 CS. The various
lightweight design measures bring about a total weight saving of some
20 kilograms compared to the BMW M3 Competition Sedan with M xDrive.
Body rigidity can be further increased by specifying a package of
high-precision strut braces for the engine compartment that have also
been engineered for lightness. The cast aluminium elements connecting
the spring strut towers to the front end feature a weight-optimised
geometry that has been precisely matched – with the help of numerical
models – to the forces applied in various driving situations.
Exclusive design features promise thrilling performance.
The new BMW M3 CS instantly announces its sharper character with a
series of individual design features. The Frozen Solid White paint
finish available for the exterior is exclusive to the latest
special-edition model from BMW M GmbH. Exposed carbon-fibre surfaces
for the roof, the two indents chiselled into the bonnet, the front
splitter, front air intakes, M exterior mirror caps, rear spoiler and
rear apron combine with the Black side skirts and M gills to provide a
stunning contrast to the new paint finish. Signal Green solid,
Brooklyn Grey metallic and Sapphire Black metallic are available as
alternative exterior colours.
The vehicle’s front end sports a weight-saving, frameless BMW kidney
grille with a stripped-back air reminiscent of racing machines.
Designed especially for this model, identifying features include red
contour lines and the “M3 CS” badging on the upper of the two
horizontal grille bars. Both the model badge at the front and its
counterpart on the boot lid have black surfaces with a red border.
The BMW Laserlight headlights included in standard specification add
another particularly striking flourish to the front end of the new
BMW M3 CS. By illuminating yellow instead of white – both during the
Welcome sequence when the vehicle is unlocked and while low beam or
high beam is switched on – they reference successful GT racing cars.
M Carbon bucket seats with exclusive surfaces and seam patterns.
Inside the new BMW M3 CS, a sports car cockpit designed with
concentrated driving pleasure and maximum performance in mind is
brought together with advanced digital technology and exclusive design
elements. The driver and front passenger are welcomed as standard by
M Carbon bucket seats in a model-specific design. Fully electric and
heated, they feature integral head restraints along with an
illuminated model badge, resulting in a unique blend of racing flair
and long-distance comfort. The use of CFRP in the structural elements
of the seat cushion and backrest as well as the eye-catching cut-outs
in the side bolsters and below the head restraints are testimony to
the seats’ weight-minimising construction.
The M Carbon bucket seats in the new BMW M3 CS are upholstered in
Merino leather and feature an exclusive design in a Black/Red colour
scheme with distinctive contrast stitching. This bi-colour finish is
repeated for the two seats in the rear compartment of the sedan. The
door panels are trimmed entirely in Black leather in both the front
and the rear, while red “CS” lettering adorns the lightweight-design
centre console. The standard equipment roster for the new BMW M3 CS
also includes M seat belts with a woven stripe pattern in BMW M GmbH
colours, door sill plates bearing the inscription “M3 CS”, an
Anthracite-coloured headliner, interior trim strips in Carbon Fibre
finish and an M Alcantara steering wheel with CFRP shift paddles and a
red centre marker.
Setup button for customising the car’s configuration.
The M-specific control/operation system includes the Setup button on
the centre console, which enables direct access to the settings
options for the engine, chassis, steering, braking system and
M xDrive. Two individually configured setup variants can be stored
permanently, together with the preferred settings for the engine note,
the DSC system, the Automatic Start/Stop function and the shift
characteristics of the eight-speed M Steptronic transmission, and then
retrieved using the M buttons on the steering wheel.
Also fitted as standard in the new BMW M3 CS is the M Drive
Professional system. Consequently, not only does the special-edition
model benefit from the M Drift Analyser and M Laptimer functions for
evaluating and recording driving skills and performance at the track,
it additionally comes with M Traction Control, whose ten stages
provide the ideal tools for pushing the car hard on closed circuits.
The M Mode button on the centre console – also part of the M Drive
Professional package – can be used to adjust both the level of driver
assistance system activity and the content shown in the information
display and optional Head-Up Display, with a choice of ROAD, SPORT and
TRACK settings.
BMW Curved Display with M-specific read-outs.
The new BMW M3 CS boasts the latest-generation BMW iDrive vehicle
experience based on BMW Operating System 8, which includes the BMW
Curved Display for the cockpit. This is formed by a 12.3-inch
information display and a control display with a screen diagonal of
14.9 inches, which are housed together behind a curved glass surface.
With its ergonomic driver-centric positioning, the BMW Curved Display
makes the already intuitive touch control even more user-friendly.
The information display’s graphical layout and the M‑style content
shown there lend themselves to a focused, performance-led driving
experience. All driving-related data as well as vehicle status and
settings information are neatly arranged within it. The familiar M
Shift Lights appear at the top of the information display, while the
driving stability system, M xDrive and traction control modes are all
indicated at the lower edge. Special widgets containing information on
the current vehicle setup, as well as tyre pressure and temperature
can be added to the control display’s home screen.
Top-class options for added pleasure and comfort during
everyday driving.
The standard BMW Live Cockpit Professional comes with functions
including the BMW Maps navigation system, the BMW Intelligent Personal
Assistant, smartphone integration, telephony with wireless charging
and a WiFi interface. The BMW Head-Up Display with M-specific readouts
and the BMW Drive Recorder are both available as options.
The new BMW M3 CS additionally offers customers a select choice of
comfort features and driver assistance systems, with the focus placed
firmly on the enjoyment of unadulterated driving pleasure. It is
equipped as standard with the latest version of Comfort Access,
two-zone automatic climate control, the Harman Kardon Surround Sound
System, Park Distance Control, Front Collision Warning, Lane Departure
Warning and the Speed Limit Info system. An alarm system, automatic
boot lid operation and the Driving Assistant and Parking Assistant
systems can be added as options.
