G-Power has decided to upgrade its tuning package tailored to the BMW M4 Coupe.

G-Power has decided to upgrade its tuning package tailored to the BMW M4 Coupe.

Almost a year ago, G-Power launched a power boost kit for the 3.0-liter inline-six TwinPower Turbo increasing output from 431 PS (317 kW) and 550 Nm (406 lb-ft) to 520 PS (382 kW) and 700 Nm (516 lb-ft). Now, a second iteration of the package (€2,750) ups the power ante to 560 PS (412 kW) at 6,500 rpm and 720 Nm (532 lb-ft) at 4,500 rpm. We did the math and it is 129 PS (95 kW) and 170 Nm (125 lb-ft) more powerful than a stock M4.

As a consequence, it’s no surprise the 0-62 mph (0-100 km/h) sprint is now done in 3.8 seconds (down by 0.3s). A standard M4 with the M Driver’s Package is capped at 174 mph (280 km/h), but G-Power’s unrestricted version will do 193 mph (310 km/h) if you go for the top speed limiter removal (€668).

Besides extracting more power, the tuner also installed a titanium exhaust system (€5,164) with quad 90-mm tips and with a remote-controlled sound flap in the rear silencer. It is 7.1 kg (15.6 lbs) lighter than the standard exhaust and can be optionally had with a carbon fiber finish.

Moreover, a set of 21-inch HURRICANE RR wheels with 245/30 ZR21 front and 295/25 ZR21 rear Michelin rubbers are available for €7,647 and can be had in Stardust Silver, Gun Metal Grey, and Jet Black. For more money, G-Power is willing to paint the wheels in any color the customer wants.

Needless to say, the exact same array of upgrades can be fitted onto the BMW M3 Sedan as well.
