The BMW you see before you isn’t the return of the legendary CSL, but BMW’s name play with the new M4 CS is designed to evoke memories of the lightweight M3 CSL special that became an icon of modern motoring in the mid 2000’s
Under the bonnet is the same twin-turbocharged inline six-cylinder engine as used across the rest of the M4 and M3 range but but tuned to develop more power. The technical specifications more closely match the engine from the M4 GTS but that edition’s specialised water-injection system has been removed.
As a result output has been boosted to 338kW, 7kW more than the M4 Competition, while torque jumps to 600Nm, a 50Nm gain compared to the Competition.
With a seven-speed dual-clutch transmission as the only available transmission BMW claims a 0-100km/h time of 3.9 seconds, shaving 0.1 seconds from the M4 Competition’s time, while official fuel consumption is rated 8.4 l/100km.
Standard brake hardware consists of four-piston calipers at the front gripping steel rotors with twin-piston calipers at the rear, or optional carbon-ceramic rotors with six-piston front and four-piston rear calipers can be added
Wheels are a new 10-spoke, lightweight, forged design with 19x9.0-inch front rims and 20.x10.0 rears clad in Michelin Cup Sport tyres.
Suspension settings have been adjusted with firmer springs and dampers and the carbon-fibre strut-brace from the GTS has also been added.
Weight-saving measure see the standard M4’s carbon-fibre roof joined by a lightweight bonnet, rear diffuser, single-piece driveshaft all of which are constructed from carbon-fibre, as a result the M4 CS weighs 1580kg in its European specification.
For all of that, BMW insists the M4 CS isn’t purely track focussed, yet that hasn’t stopped them from recording 7 minute 38 lap time around the Nurburgring putting the M4 CS just 10 seconds off the pace of the M4 GTS.
Production of the M4 CS will be limited, though at this stage BMW is yet to confirm just how many are to be built, with estimates suggesting between 2000 and 3000 cars may be produced with no confirmation of an Australian allocation at this stage. Pricing in Europe sees the M4 CS start at roughly A$43,000 above a regular M4 which could potentially make the M4 CS a circa A$193,000 proposition in Australia, though final pricing may differ if the car arrives locally.
