PistonHeads takes a right-hand-drive BMW M4 GTS to the Castle Combe race track for some proper laps. Compared to the normal M4, the M4 GTS engine delivers a 16% higher output (500 PS rather than 431 PS) at 6250 rpm (vs 5500 rpm on the regular M4). Maximum torque is also 10% higher, peaking at 600 Nm (vs 550 Nm) but available on a narrower engine speed range (4000-5500 rpm whereas the M4 peak torque is fully available under the driver’s left foot between 1850 and 5500 rpm).

This boosted by water M4 is catapulted to 100 km/h in just 3.8 seconds (half a second less than the normal M4) and can achieve a top speed of 305 km/h (vs 250 km/h, in both cases electronically restrained). Despite the output upgrade, average consumption equals the one returned by the M4 (8,8 l/100 km).

The use of very lightweight materials such as carbon fiber, aluminum, titanium and stiffness reinforcing polymers – alongside some parts with a more basic design, such as door handles or the center console – have been instrumental to allow the M4 GTS to weigh 1510 kg, shedding 62 kg from its normal weight, which means that each pony is not forced to carry a jokey with more than 3 kg on its back.
