G-Power Supercharges the BMW M3 E46 and Z4M to 450HP

This time, BMW 'super tuner' G-Power has turned its attention on two previous generation 'M' sports cars, the M3 E46 and the Z4M with the presentation of a somewhat tamer performance package than what we're used to from the German company. At the heart of the tuning program is a new large ASA TM I 20 centrifugal supercharger that boosts the M3 and Z4M 3.2-liter straight-six engine's output from 343HP and 365Nm to 450HP and 450Nm or 331.9 lb-ft of torque.

The 107 horsepower boost helps improve acceleration from standstill to 200km/h or 124mph from the standard M3 E46 Coupe's 18,1 seconds to 14,7 seconds, making it even faster than the current 420HP-strong M3 V8 that needs 15.8 seconds for the same sprint.

To improve road handling, the performance package for both the M3 E46 and Z4M include a continuously height-adjustable G-Power coil-over suspension RS with nine selectable settings each for bound and rebound.

The M division sports cars ride on lightweight 20-inch alloy wheels shod in Michelin Pilot Sport tires (245/30 ZR 20 at the front and 285/25 ZR 20 at the back) that allow a top speed of more than 300km/h or 187mph.

Though not included in the basic package, G-Power also offers a sports rear muffler that produces a deeper and more sonorous tone.

G-Power Receives First Batch of BMW M3 GTS Coupes, Expect at Least 600HP

With 450HP on tap, the limited edition BMW M3 GTS is not only more powerful than the stock M3, but it’s also lighter and comes with a full-blown racing suspension, making it arguably the best 3-Series model of its generation.

Nevertheless, famed BMW tuner G-Power thinks something’s missing, namely “the ultimate output”. That’s why the Autenzell-based specialist will modify three GTS models, two of which have already arrived at its headquarters in Germany.

G-Power’s SK II CS “Sporty Drive” supercharger will be adapted to work with the 4.4-liter V8 engine pushing output to over 600HP. There’s no word on any other upgrades, but buyers can expect an improved braking system and additional chassis tweaks.

In any case, G-Power is confident that the spiced up M3 GTS will give the Porsche 911 GT3 RS a run for its money. "After this modification the BMW M3 GTS can finally show the armada of Porsche 911 GT3 RS who’s the boss at the various clubsport racing events," said G-Power in a statement.

We’d say that's to be seen, but time will surely clarify this dilemma.
