As its 50th birthday celebrations gathered pace, BMW M GmbH unveiled a new BMW M4 CSL, fusing old-school racing passion with innovative technology to create the ultimate performance experience. Its character is defined by a power hike of 40hp over the current BMW M4 Competition Coupé to 550hp and a host of meticulous weight-saving measures. With years of experience in working with carbon-fibre-reinforced plastic (CFRP) for body, chassis and interior components, BMW M engineers have managed to restrict the special edition's kerb weight to 1,625kg (in standard specification in the German market). As a result, the new BMW M4 CSL is 100kg lighter than the BMW M4 Competition Coupé (in standard specification in the German market), sprinting from 0 to 62mph in 3.7 seconds, and 124mph in just 10.7 seconds - 1.8 seconds quicker than the BMW M4 Competition Coupé. Top speed is an electronically limited 190mph.
Modified six-cylinder engine, eight-speed M Steptronic transmission and rear-wheel drive for the ultimate performance experience
Modifications for the new BMW M4 CSL contribute to a maximum output of 550hp when the rev counter hits 6,250rpm - an increase of 40hp over the BMW M4 Competition Coupé. Peak torque of 650Nm is on tap from just 2,750rpm and sustained all the way up to 5,950rpm. A bespoke engine mounting and rigorous application of lightweight design principles ensure the new BMW M4 CSL achieves an even bigger gain in dynamic prowess than this extra dose of M power would suggest. Power was boosted by increasing charge pressure at the same time as making model-specific tweaks to the engine management. Yet this potent version of the 3.0-litre engine is also extremely efficient, with WLTP-calculated fuel consumption of 28.0 - 28.8mpg and CO2 emissions of 227 - 222g/km.
M Drive Professional and M Mode button
The standard M Drive Professional helps the driver to make improvements in their pursuit of the ideal line and faster lap times. For example, dramatic use of oversteer and opposite lock is recorded by the M Drift Analyser, while a steering-on-the-throttle performance rating comprises a mark between one and five stars with a comparison against the driver's previous best. An overall view also displays the number of drifts recorded, the distance covered while sideways and other facts and figures. The M Laptimer, meanwhile, sends a variety of information to both the instrument cluster and the BMW Head-Up Display. This allows the driver to keep an eye on how much quicker they are than their current fastest lap. The display shows the number of laps completed so far, distance covered and the duration of the current stint. Drivers can also analyse the data in detail with the BMW M Laptimer iPhone app and share it with the online community.
