Key Points: 3.0-litre 543bhp Twin-Turbocharged Straight 6, 1 of only 1000 produced, Delivery Mileage, Carbon Fibre Styling, Carbon Fibre Bucket Seats

The G82 BMW M4 is already the fastest, best-handling BMW M4/3 to date. Blitzing everything in its class on the day of release. Now BMW has decided they weren't showing their dominance quite enough. Thus, the M4 CSL was born. The 3.0-litre straight six has been upgraded to 543bhp, and 649nm of torque and only comes in rear-wheel drive as opposed to the sensible xDrive option for the M4 Competition, showing just how performance-oriented the CSL is.

The increased power is the tip of the iceberg for the CSL, as it also features a new carbon fibre bonnet, roof, boot lid, wing mirrors, front splitter, and rear diffuser. BMW has taken out the rear seats, all in pursuit of weight-saving.
