BMW Goes Back To The Future With M4 CS.

BMW Australia has released details of the forthcoming M4 CS. With a whopping 338 kilowatt engine and packing a torque punch of 600 Nm, the hot two door will start from $211,610.00 with an expected release date of late 2017.
It’ll sit at the top of a refreshed M4 range, comprising the M4, M4 Pure, M4 Competition and also sources elements from the limited edition M4 GTS.The CS also harkens back to the 1960s, with the CS nomenclature first seen on the beautiful 3200 CS of 1962. It swapped to the 2000 CS in 1965, and the evocative 1971 E9 Series 3.0 CS. The current version uses BMW’s legendary straight six powerplant, with a 3.0L capacity. There’s two mono-scroll turbos strapped to the engine, which features a rigid closed-deck cylinder block, forged crankshaft and arc-sprayed cylinder walls, the six-cylinder is light and strong with minimal friction loss and outstanding high-rev capability, all the way to a 7,600rpm red-line.The turbos dump unwanted air via a dual-branch sports exhaust system with quad 80mm tailpipes which adds an aggressive acoustic while keeping back pressure as low as possible. Electronically-controlled exhaust flaps further contribute to exhaust volume and gas flow depending on the vehicle’s load state and selected drive mode.

Changes in the engine’s electronic management system leads to a 7kW power increase over the M4 Competition, with 338kW available at 6,250rpm. Vitally, peak torque is improved by 50Nm to a round 600Nm, a match for the legendary M4 GTS. According to the BMW M dynamometer charts, the M4 CS peak torque figure is generated from 4,000rpm to 5,380rpm.There’s a specific chassis tune for the M4 CS, with the aluminuim based structure allowing a driver to choose from Comfort, Sport, and Sport+. Up front is a lightweight double-joint spring strut layout, with the five-link axle featured at the rear. All suspension links and wheel carriers are made from forged aluminium. The M4 CS will ride on 10 spoke forged alloy wheels, with the front being 9 x 19 inches and weighing just 9 kilos, whilst the rears will weigh just under ten kilos and be 10 x 20 inches in size. Brakes are four piston fronts and twin pistons at the rear.The whole car weights under 1600 kilos thanks to lightweight carbon-fibre and carbon fibre reinforced plastic (CFRP), with an exposed carbon fibre diffuser that is specific to the CS and helps to substantially reduce front axle ‘lift’. The twin headlights are LEDs, the bonnet is CFRP, as is the roof and weighs six kilos lighter than a steel roof. The rear diffuser is also CFRP and is borrowed from the M4 GTS as is the exclusive Organic LED rear lighting system.It’s more track and sports focused inside than a regular M4, but there’s still plenty of luxury, with Alcantara trim on the door armrests, passenger side dash tim which includes an etched CS designation, on the centre console and mixed in with leather on the seats. A leather wrapped tiller is available as a no-cost option.

There’ll be a Head Up Display with M specific content, BMW’s Connected Drive Services, hands free Bluetooth, digital radio and parking distance control for the front and rear sensors. Two metallic paint options – Black Sapphire and San Marino Blue – are available as standard equipment, while the non-metallic Alpine White is a no-cost option.In addition, two special BMW Individual paint finishes are available for $4,400*, the bespoke Lime Rock Grey and the Frozen Dark Blue II.

M Carbon Ceramic brakes, roller rear sunblind, sun protection glazing, a headlight washer system, TV function and Apple Car Play integration are also optionally available.
