Shanghai - BMW will unveil the M4 CS, a model that they say fills the gap in the line-up between the M4 Coupe Competition Package and the hardcore M4 GTS.
BMW South Africa confirmed the M4 CS will be available during the third quarter of 2017.
Built in Munich, the M4 CS continues the decades-long tradition of M special editions which began in 1988 with the E30 M3 Evolution.
The M4 CS also sees BMW M GmbH introducing a new nomenclature for its models. Positioned above the standard M models will be the performance-boosted Competition versions. Then come the CS special-edition models, a notch higher still. Positioned on top are the performance-maximising “brand shapers” which display a clear motor sport or club sport character but are also fully road legal.
Limited to 280km/h
The 3.0-litre engine's output is raised by 7kW to 338kW. The automaker says the 0-100km/h has now dipped below four seconds to 3.9 seconds. The top speed of the M4 CS, which comes as standard with the M Driver’s Package, is electronically limited to 280km/h.
It uses the usual seven-speed M Double Clutch Transmission (M DCT) with Drivelogic. BMW says the transmission uses a separate oil cooler and enables both automated gear changes and manual interventions using the shift paddles on the steering wheel.
The suspension of the new BMW M4 CS largely mirrors that of the M4 with Competition Package. The links and wheel carriers at both the front and rear axles are made from forged aluminium and are therefore extremely light. That keeps the unsprung masses low and benefits driving dynamics. The M4 CS is fitted as standard with Adaptive M suspension.
There's the usual three driving modes (Comfort, Sport and Sport+) which can be engaged at the touch of a button.
The CS is fitted as standard with Michelin Pilot Sport Cup 2 tyres (front: 265/35 R 19, rear: 285/30 R 20). These semi-slick cup tyres are also road-legal. The M4 CS can also be ordered with Michelin Sport road tyres at no extra cost.
Inside the CS expect lightweight M sports seats trimmed in leather/Alcantara and more weight-saving measures such as the door panel trim made from compacted natural fibres and featuring pull loops. The bonnet – with its characteristic air outlet rearwards of the powerdome – and roof are made from the lightweight, extremely rigid and high-tech material carbon fibre-reinforced plastic (CFRP).
