Engine and performance
The latest-specification twin-turbocharged 3.0-litre straight-six punches well above its weight, with an impressive 338kW power peak.

This is backed up by a strong torque curve that peaks at 600Nm – some 50Nm higher than the already-impressive tune of the M3 Pure and M3 Competition.

Featuring a rigid closed-deck cylinder block, forged crankshaft and arc-sprayed cylinder walls, the six-cylinder is light and strong with minimal friction loss and outstanding high-rev capability, all the way to a 7,600rpm red-line.

This powerhouse uses two mono-scroll turbochargers for superb response. Thanks to a combination of high-precision, direct fuel injection, fully variable VALVETRONIC valve timing and DOUBLE VANOS fully variable camshaft timing, the M3 CS’s engine offers strong throttle response as well as efficiency and outstanding specific power.

A lightweight magnesium oil sump ensures lubrication at up to 1.4g cornering load.

A dual-branch M sports exhaust system with quad 80mm tailpipes adds an aggressive acoustic while keeping back pressure as low as possible. Electronically-controlled exhaust flaps further contribute to exhaust volume and gas flow depending on the vehicle’s load state and selected drive mode.

Changes in the engine’s electronic management system leads to a 7kW power increase over the M3 Competition, with 338kW available at 6,250rpm. Vitally, peak torque is improved by 50Nm to a round 600Nm, a match for the legendary M4 GTS. According to the BMW M dynamometer charts, the M3 CS peak torque figure is generated from 4,000rpm to 5,380rpm.

Equipped with the M Driver’s Package as standard, the BMW M3 CS is electronically- limited to 280km/h. Zero to 100km/h acceleration is achieved in only 3.9 seconds while NEDC fuel consumption is rated at 8.4L/100km.

Power is transmitted to the rear wheels via a seven-speed dual-clutch transmission, which boasts its own oil cooler for sustained operation at even the highest loads. From there, drive is split across the rear axle via the electronically-controlled, multi-plate Active M Differential. This limited-slip unit can actively lock in a range from zero-100 per cent to maximise drive in the prevailing conditions, thanks to a combination of inputs taken from the DSC system, as well as accelerator position, vehicle yaw and the difference in wheel speeds.

Those seeking a fast getaway can also activate the M Launch Control function, which allows the driver to dial up a pre-selected rev range before lifting the brake for a traction-maximised burst off the line.

Should you wish for more manual control, the DSC system offers M Dynamic Mode, which loosens the stability control systems and engages Dynamic Traction Control. Full DSC deactivation is also possible.

A chassis designed for the sharpest response
The BMW M3 CS features specific tuning parameters for the Adaptive M Suspension, Active M Differential, DSC, ABS, M DCT and M Servotronic steering systems.

Taking the lead from the dynamic M3 Competition, the M3 CS’s aluminium-intensive suspension design can be adjusted across three settings: Comfort, Sport and Sport+.

The front suspension features a lightweight double-joint spring strut layout, while a five-link axle is used at the rear. All suspension links and wheel carriers are made from forged aluminium for high rigidity and light weight.

The suspension’s zero play ball-joints take a direct lead from motorsport, as does the rear axle sub-frame’s rigid bolted connection to the body structure.

As with the suspension damping, the driver can choose between Comfort, Sport and Sport+ settings for the electrically-assisted power steering.

Forged 10-spoke light-alloy wheels in Orbit Grey take their inspiration from the 2016 DTM championship-winning BMW M4 DTM racer of Marco Wittmann. Weighing around 9kg per corner, the front wheels measure 9J x 19 inches, with larger 10J x 20-inch rims fitted to the rear and weighing less than 10kg each.

These advanced road wheels are fitted with aggressive Michelin Pilot Sport Cup 2 tyres that measure 265/35R19 up-front and 285/30R20 at the rear. These tyres – seen on the M4 GTS – offer maximum dry weather grip and traction. A road-biased but still sports-focused Michelin Pilot Super Sport tyre, measuring the same diameter, can be alternatively optioned at no additional cost.

Braking is provided via the M3 Competition’s M Compound Brake setup. Four-piston front brake calipers are backed up by two-piston rears.

Those seeking the ultimate in braking can specify the M Ceramic braking system, which features six-pot front calipers and four-pot rears along with extremely lightweight brake discs.

Subtly aggressive exterior adds massive road (or track) presence
Immediately recognisable, the BMW M3 CS cuts a truly distinctive figure.

Extensive use of carbon fibre and carbon fibre reinforced plastic (CFRP) is evident and contributes to a weight of only 1,585kg (according to EU regulations, without driver).

Starting from the front, an exposed carbon fibre diffuser that is specific to the CS substantially reduces front axle ‘lift’. Twin LED headlights and black-painted kidney grille slats sit above the aggressive, three-part front apron and pronounced intakes that feed air to the engine and braking system.

CFRP forms the bonnet and its distinctive powerdome, which also aids under-bonnet heat dissipation and reduces weight by 25 per cent over the standard M3 item. The roof is also CFRP and is 6kg lighter than a conventional steel roof, while simultaneously adding rigidity and lowering the car’s centre of gravity.

Moving to the rear, the prominent CFRP rear diffuser is inspired by the M4 GTS and aids aerodynamic stability, while the exposed carbon ‘Gurney’ boot-lip further encourages a reduction in lift.

Exterior trims benefit from the BMW Individual High-gloss Shadow Line finish. Black high- gloss finishers abound, the treatment applied to the side window trims and recess covers, the kidney grille and the side-mounted M ‘gills’ behind the front wheels. Darkened rear lights add further distinctiveness, while the rear M3 CS badging is finished in silver chrome.

Five exterior paint finishes will be offered: Metallic options, in the form of San Marino Blue and Black Sapphire are standard offerings. Customers can also option the non-metallic Alpine White at no cost. Special colours Lime Rock Grey and Frozen Dark Blue II are also available as cost options.

Lightweight Luxury: The M3 CS interior
Although more focused than the regular M3, the BMW M3 CS’s interior still provides a high level of comfort and standard specification.

Stepping over the specific M3 CS door sill panels, you are welcomed by tactile Alcantara trim features that highlight the cabin. This fine, light-weight fabric is applied to the lower door armrests (with the upper sections in Merino leather), passenger side dash trim (with etched ‘CS’ designation) and centre console.

Familiar to M3 Competition owners, the sports seats in two-tone Silverstone/Black Merino leather offer scalloped cut-out sections and provide effective lateral support, even in extreme cornering.

The seat upholstery features grey contrast stitching, while the stunning BMW M tri-colour stripe has been integrated into the seat belts.

As per the M4 GTS Alcantara is the chosen trim for the M multi-function steering wheel. The wheel showcases blue and red BMW M contrast stitching and a race-inspired ‘12 o’clock’ marker.

BMW’s latest iDrive6 infotainment system is fitted as standard to the BMW M3 CS.

Accessed via the standard Navigation system Professional 8.8-inch high-definition screen, this system features an easy-to-access, customisable tiled layout and simple operation via touch screen, iDrive controller or natural voice control.

Automatic climate control and a specially adapted version of the 12-speaker sound system ensure passengers can enjoy a comfortable cabin space while commuting.

Condition Based Servicing
All maintenance requirements for the BMW M3 CS is controlled by the Condition Based Servicing (CBS) system.

With CBS, sensors and advanced algorithms monitor and calculate the conditions in which a vehicle is used, including mileage, time elapsed since its last service, fuel consumption and how a vehicle is driven. Based on the information captured, maintenance requirements are determined, identifying whether an annual vehicle inspection or oil service is due.

Selected BMW service and maintenance costs can be covered by a single, one-off advance payment with BMW Service Inclusive (BSI), which is available in two packages: Basic or Plus.
