BMW tuning expert G-Power from Germany got their hands on a few BMW M4 GTS (F82) as customers of the limited edition Bavarian sports coupe were looking for some additional power. G-Power was one of the first tuners to release their tuning program for the M4 GTS, unlocking a significant extra amount of power through a comprehensive ECU upgrade.
As standard the very capable GTS produces 500 hp (326 kW) and 600 Nm of torque from 4,000 to 5,500 rpm. G-Power’s Bi-Tronik 2 V3 ECU upgrade brings the M4 GTS’ total output to an even more impressive 615 hp (411 kW) and 760 Nm of torque and has a price tag of just over €3,000. The power infusion reflects in the GTS’ performance as follows: 0-100 km/h now takes 3.6 seconds and the speedometer will max out somewhere North of 320 km/h.
G-Power will gladly remove the Vmax for you, at a price of €668,00. Extra upgrades come in the form of a turbocharger modification, and custom downpipes without catalysts. To top it all off G-Power have a splendid set of 21-inch Hurricane RR forged alloy wheels on offer.
