A new report states the BMW M4 GTS due next year will actually wear the iconic "CSL" moniker.
According to Automobile Magazine, the higher specification version of the M4 will likely be called Coupe Sport Lightweight (CSL) to indicate it will lose as much as 220 lbs (100 kg) compared to the standard M4 Coupe (3,530 lbs manual / 3,585 lbs automatic) . The diet will be possible by removing some of the comfort features, installing manually adjustable carbon fiber front seats while the rear bench is going to be eliminated. At an additional cost, customers will have the possibility of ordering an optional roll cage.
The BMW M4 CSL is believed to receive the aerodynamic bits and pieces of the M4 Coupe MotoGP safety car so expect a front splitter, fender blades, sleeker side mirrors, rocker-sill extensions, rear diffuser, underbody cover and a big rear wing. Also from the safety car it will borrow the water injection system which will add approximately 22 lbs (10 kg) commanded by the water pump and tank.
While the regular BMW M4 Coupe has 431 PS (317 kW) and 550 Nm (406 lb-ft), the uprated six-cylinder 3.0-liter engine inside the M4 GTS will reportedly develop 500 PS (368 kW) and 600 Nm (443 lb-ft). By slashing weight and adding power, the GTS will probably need less than four seconds to cover the 0-62 mph (0-100 km/h) sprint, thus making it significantly quicker than the DCT-equipped M4 which does it in 4.1 seconds (+0.2s for manual).
As a final note, the report specifies only 750 units of the 2016 BMW M4 GTS are planned at a yet undisclosed price tag.
