The BMW M3 CS is 20kg lighter than the M3, and pushes out a total 543bhp, thanks to extensive use of carbon fibre and a raised turbocharger boost pressure.

BMW has revealed the new M3 CS.

The M3 CS stands out from the M3 Competition thanks to an upgraded 3.0-litre six-cylinder, allowing it to push out a total of 543bhp, 40bhp more than the M3 Competition, and close enough to bother the 3.0 CSL that was revealed a few months back.

A dual-branch exhaust system utilises featuring electronically and utilising a titanium rear silencer help to shave 4kg off the M3 CS
This power upgrade comes courtesy of modifications that include the use of weight-saving cylinder bores with a wire-arc sprayed iron coating, a forged lightweight crankshaft, as well as 3D-printed cylinder heads.

The maximum charge pressure of the two mono-scroll turbochargers has also been raised in this application, from 1.7bar to 2.1 bar, while the engine management system has also received model-specific tweaks.

BMW further states that the oil supply and cooling system for the M3 CS has been specially designed for track use.

A dual-branch exhaust system, featuring electrically controlled flaps and a titanium rear silencer which ends in two pairs of tailpipes painted in matt Black, promises an emotionally stirring soundtrack for the BMW M3 CS.

The car's 3.0-litre unit has had its turbocharger boost pressure raied to 2.1 bar, allowing it to push out a total of 543bhp and 650Nm of torque
An eight-speed M Steptronic transmission, as well as a BMW M xDrive all-wheel drive system paired with an Active M Differential at the rear axle all put this power onto the road. Combined, they allow the BMW M3 CS to complete the century sprint in just 3.4 seconds.

And on the twisty roads, there's a model-specific setup for the adaptive M suspension on the new BMW M3 CS, alongside M Compound brakes, with calipes painted in a choice of Red or Black. If these don't appeal, there's additionally the option to get M Carbon ceramic brakes, with calipers painted in matt Gold or Red.

The M3 CS will also come with BMW's M Drive Professional system, which for this model, comes complete with the M Drift Analyser and M Laptimer functions for evaluating and recording driving skills and performance at the track, as well as a 10-stage M Traction Control system.

The M3 CS comes with M Carbon bucket seats, as well as carbon fibre shift paddles on the steering wheel
Forged M light-alloy wheels will also don track tyres specially developed for the M3 CS, although customers can also opt for high-performance tyres as a no-cost option.

As is fitting for a CS model, carbon fibre-reinforced plastic has been utilised on the bonnet, front splitter, front air intakes, exterior mirror caps, rear diffuser and rear spoiler. These, alongside the M Carbon bucket seats and titanium rear silencer, mean the M3 CS weighs in at 20kg less than the BMW M3 Competition Sedan with M xDrive.

Other, visual differences between the M3 CS and the M3 Sedan include a weight-saving, frameless BMW kidney grille at the front, which sports red contour lines and 'M3 CS' badging on the upper of the two horizontal grille bars.

This grille is also flanked by BMW Laserlight head lights, which illuminate yellow instead of white, a reference to the firm's successful GT racing cars. Both the model badge at the front and its counterpart on the boot lid, meanwhile, have black surfaces with a red border.

The BMW M3 CS comes with Frozen Solid White metallic paint, although Signal Green solid, Brooklyn Grey metallic and Sapphire Black metallic are available as alternative exterior colours.
