THE M4 CSL HAS ARRIVED! A SPECIAL, SPECIAL EDITION!

The acronym CSL is for “Competition, Sport, Lightweight” and thanks to new technologies and processes, the BMW M4 has been trimmed and tucked in all the right places, the rear seats are non-existent and the motor has seen a tweaking with a bunch of things inspired by another iconic BMW, the M4 GT3. Of course, it’s under that hood where some proper magic happens, the usual twin-turbocharged inline six-cylinder is in play, and the tuning has seen the boost level rise from 1.7 bar to a much higher 2.1 bar, and we all know that raising the boost raises the power and so this limited edition BMW M4 CSL now produces 405 kW (550 hp) with torque up at a very decent 650 Nm. The engineers decided that the M4 CSL should not weigh more than 1 625 kg, and this gives a brilliant power to weight ratio of 4.01 kg per kilowatt.

As said, light weight is even in the name of the car, and that’s why there’s only two M Carbon full bucket seats, deleted seat belt mechanisms, extra-lightweight M Carbon ceramic brakes as well as a set of specially created lightweight alloys, springs and struts. Soundproofing was swapped to ultra-lightweight sound insulation and some components are now made from carbon-fibre-reinforced plastic to save even more weight - the roof, bonnet and boot lid are also produced with this lightweight high-tech material - even the centre console is too. A titanium rear silencer saves weight in the exhaust system and some small detail modifications to the BMW kidney grille, rear lights, floor mats and automatic climate control shave off even more weight.

A CSL needs to be instantly recognisable from other cars in the same model range, and so this BMW M4 CSL features an exclusive exterior paint finish called Frozen Brooklyn Grey metallic as standard, and it works great with the exposed carbon-fibre surfaces and red accents. There’s even a choice, customers have the option to specify their new BMW M4 CSL in Alpine White solid or Sapphire Black metallic - but why would you? The surfaces of the indents are highlighted additionally by red outlines, they also emphasise to the fins on the CFRP roof of the new BMW M4 CSL, the contours of its side sills, the black model badges, and the model-specific CFRP splitters and air curtain inserts in the front apron. The optional BMW Laserlight headlights in yellow that actually shine yellow when unlocking the doors and when the low and high beams are switched on - an homage to GT racing cars. The LED rear lights of the new BMW M4 CSL now feature glass covers with intricate light threads woven into them that are illuminated using laser technology that creates a highly distinctive light signature that is recognisable from a long distance. Also specified as standard are the tasty 19 / 20-inch forged M light-alloy wheels in an exclusive cross-spoke design, fitted with high-performance tyres specially developed for the M4 CSL in size 275/35 ZR19 and 285/30 ZR20 respectively.
