There’s still no confirmation as to when
the new G80 BMW M3 will make its debut, and if you’re an owner of a G20/G21
M340i xDrive in desperate need of more power, G-Power is here to lend a helping
hand.
The German tuner has updated its tuning
programme for the model with a new GP-510 upgrade kit, which goes well beyond
its GP-470 and GP-420 offerings. With the upgrade, the M340i’s 3.0 litre
turbocharged straight-six now makes 510 PS and 690 Nm of torque, which is
significantly more than stock (374 PS and 500 Nm) and closely matches the
Mercedes-AMG C 63 S’ 4.0 litre biturbo V8 that serves up 510 PS and 700 Nm.
G-Power introduced a new
ECU mapping along with a stainless steel downpipe, a free-flowing 200-cell
catalytic converter, a stainless steel, valved exhaust system with to four
90-mm tailpipes, and a larger turbocharger. Performance-wise, the GP-510 lowers
the M340i’s zero to 100 km/h sprint time to just 3.7 seconds, which is 0.7
seconds quicker compared to the standard car in sedan guise. The company can
also increase the speed limit cap from 250 km/h to 330 km/h for a little extra.
If the GP-510 package is too much to take,
the lesser GP-470 (0-100 km/h in 3.8 seconds) gets the same upgrades as the
GP-510 but without the larger turbo to make 470 PS and 650 Nm. At the bottom of
the chain is the GP-420 (zero to 100 km/h in four seconds), with only a
software tweak to make 420 PS and 600 Nm.
Beyond the power upgrades, customers can
also spruce up the exterior with a set of Hurricane RR 20-inch forged wheels
that help to enhance the performance further by reducing unsprung and rotating
masses.
