M760Li launch but were sworn to secrecy. This has required some degree of self control, given the instinctive reaction when being shown a brand new M car is to tell as many people as possible all about it. Now we can!
Headlines. The CS gets a bit more power from its 3.0-litre twin-turbo straight-six, now delivering an extra 10hp over the Competition Pack M4 (and 29hp over the standard car) for a total of 460hp. Torque gets a bigger boost, climbing from 406lb ft to 442lb ft - same as the track-ready M4 GTS in fact. There's a token tenth off the Competition Pack's 0-62mph time - now 3.9 seconds - and a raised top speed limiter that calls time at 174mph, but you'd expect a healthy gain in mid-range shove and overall response based on those numbers. Indeed, BMW is claiming a 7min 38sec 'ring lap for the car; that's 10 seconds down on the 500hp GTS but 911 GT3 pace of a generation ago. Quick enough, in other words.
Further GTS influence comes in the fixtures and fittings, including that car's vented carbon fibre bonnet. Unique and functional CS-spec aero, including a front splitter and relatively subtle rear lip spoiler, plus some really, really tasty wheels, mark it out from regular M4s. These are 19-/20-inch in diameter; Cup 2 tyres are standard. Brakes and suspension have also been tweaked, the latter with undisclosed "even sportier" settings and the exhaust is from the Competition Pack car. Inside there's a full complement of seats and gizmos plus a nod to an overall 32kg weight saving offered by a new 'lightweight fibre' used for the door skins. The signature San Marino Blue looks fabulous (Lime Rock Grey is the other exclusive colour option) while news that it's DCT only will be greeted with dismay by purists but pragmatism by a market dominated by two-pedal transmissions. Whisper it but our experience of the M4 is that it works better with the DCT anyway.
