560hp BMW M3 and M4 by G-Power

With 425 hp on tap in standard guise, the BMW M3 and M4 duo certainly aren’t slouches. Nevertheless, German BMW tuning specialist G-Power has unveiled its host of performance modifications for the pair of sports cars.

For starters, G-Power has created its Bi-Tronik 2 V2 ECU remap for the M3/M4’s twin-turbocharged 3.0-litre six-cylinder engine. Elsewhere, custom downpipes have been installed as has an expensive titanium exhaust system with four 90 millimetre tailpipes. The results of these changes see power rise to 560 hp at 6500 rpm and 720 Nm of torque at 4500 rpm. As a result, the G-Power BMW M3 and M4 will sprint to 100 km/h in a mere 3.8 seconds as well as a top speed of 310 km/h.

Alongside the performance tweaks, G-Power has created a custom set of wheels for the cars. The 21-inch Hurricane RR forged wheels are wrapped in 245/30 and 295/25 rubber and feature a refined, twin-five spoke design.
