G-Power is introducing an upgrade program for the 2014 BMW M3 Sedan & M4 Coupe duo.

It's been a year since BMW launched the new M3 and M4 so it shouldn't come as a surprise that more and more tuners are working on packages to further boost the appeal of both cars. G-Power is one of them and they are presenting a full upgrade kit which focuses on the 3.0-liter inline-six TwinPower Turbo engine that in its stock configuration puts out a more than decent 431 HP (317 kW) and 550 Nm (406 lb-ft).

By optimizing the engine's electronics and making other tweaks, G-Power was able to bump total output to 520 HP (382 kW) at 5,500 - 7,300 rpm while torque has increased to 700 Nm (516 lb-ft) in the 1,850 to 5,500 rpm range. The additional oomph costs €3,358 and lowers the 0-62 mph (0-100 km/h) sprint time by 0.2s to 3.9 seconds while 0-124 mph (0-200 km/h) takes 11.8 seconds. Top speed can be lifted from 174 mph (280 km/h) to more than 202 mph (325 km/h) when opting for the V-MAX lift kit priced at €3,451.

Those who are willing to pay more can get the 20-inch HURRICANE RS forged wheel set with Michelin tires available for €7,998 while the tuner’s GM4-RS height- and pressure-adjustable threaded undercarriage is an extra €2,427.
