With a 0-62mph sprint of 3.3sec, it's 0.1 quicker to the mark than the regular M5 and the E63 S. With a 0-124mph run of 10.8sec, it also has a 0.3sec improvement over the standard M5.
Its engine delivers peak torque of 553lb ft from 1800rpm, the same as the regular M5’s, but it's produced over a 200rpm-wider range that ends at 5800rpm. BMW says the model gets “even more direct responses and bespoke chassis tuning to ensure a race-inspired driving experience”.
Power is sent to all four wheels via the same eight-speed M Steptronic transmission and xDrive all-wheel-drive system as the standard M5. There's an Active M Differential at the rear axle to enhance traction and give the car its rearward power bias.
Changes over the standard M5 include BMW's M Sport exhaust system as standard, the volume of which can be adjusted via a button, as well as new engine mounts with a higher spring rate to provide faster engine responses and help to increase structural rigidity across the front of the car. The model also sits on more performance-focused suspension that reduces body roll and lowers the ride height by 7mm.
