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.

G-Power’s BMW M5 HURRICANE GS is the World's Fastest LPG-Powered Car

After the standard BMW M5 and M6 Hurricane editions, BMW tuning specialists G-Power has now released a more eco-friendly iteration of the same package, in the form of the LPG-powered Hurricane M5 GS.

The German firm's engineers performed several modification to the M5 and M6 Hurricane's 5.0-liter bi-supercharged V10 engine which now comes with one fully sequential five-cylinder LPG system per cylinder bank. G-Power says the benefits of LPG fuel are both economical and ecological in nature, as LPG is not only around 50 percent less expensive per liter than petrol, it also reduces CO2 emissions by about 15 percent.

As an added bonus, the V10 is slightly more powerful than its gasoline counterpart producing 660-horsepower (+25HP) and 650Nm of peak torque at 5,500 rpm.

The M5 Hurricane GS can go from standstill to 100 km/h (62 mph) in only 4.6 seconds and reach the 200 km/h (124 mph) mark in 11.4 seconds, while topping out at 333 km/h (207 mph), which, according to the tuning firm, makes it the world’s fastest LPG-powered car.

For improved stability and handling, the sports saloon has been fitted with a G-Power RS coil-over sport suspension, high performance braking system and lighter, 20-inch Silverstone Clubsport alloys, clad in 255/35 front and 285/30 rear tires.

New BMW Z4 Roadster Receives the G-POWER Treatment

The Germans at G-Power have released their first take on the second generation BMW Z4 E89 hardtop-roadster. The tuning firm's performance package for the new Z4 includes a power kit for the sDrive 35i's 3.0-liter twin-turbocharged inline six engine along with suspension and wheel/tire upgrades. We suspect that it won't be long before G-Power unleashes a 400HP+ beast based on the Z4 but until then, let's see in detail what the company has prepared for the German roadster starting off with the engine kit.

The Z4 sDrive 35i's twin-turbocharged inline six benefits from the BI-TRONIK performance module that that pushes the factory engine's output from a standard 306HP and 400Nm (295-lbs/ft) of torque to a more satisfying 345HP and 480Nm (354-lbs/ft) of torque. G-Power claims that with this kit, the 345HP Z4 Roadster can accelerate from 0 to 100km/h (62mph) in 4.7 seconds, or half a second faster than the factory model.

G-Power's offerings also include a new coil-over suspension and a more sonorous stainless steel sport rear muffler with four tail pipes. While the tuning firm has not released any type of aero parts (yet), Z4 owners can equip their car with a new set of 20-inch lightweight alloy wheels wrapped in Michelin Pilot Sport rubber (255/30 ZR 20 up front and 295/25 ZR 20 at the rear).

And now for the prices. The cost for the 20 inch alloy wheels along with the Michelin tires is €4,474 while the coil-over suspension is €1,256 and the rear muffler, €1,508. As for the engine kit, prices have been set at €1,978 but unless you know your way around the engine bay, you'll have to pay another €403 to get it installed.

G-Power Transfers BMW M5 Hurricane RR Supercharger Tech to the E85 Z4 Roadster

German tuner G-Power has decided to share some of the technology found on the 800-horsepower M5 Hurricane RR and M6 Hurricane RR with the masses by offering a modified version of the supercharger system on the [previous generation] E85 BMW Z4 as well as the E46 Series with the 3.0-liter straight-six engine. On both models, the redesigned SK Plus supercharger system replaces the previous ASA TM3 supercharger.

The geometry of the compressor has been modified as has the housing, resulting in a more efficient build-up of boost in the middle rev-range. With a 0.3 bar pressure boost, the SK Plus kit increases output by 55 ponies, to 286 hp and 345 Nm (255 lb-ft). Thanks to the extra oomph, the tuned Z4 accelerates from standstill to 100 km/h (62 mph) in 5.4 seconds.

To be able to wring out every bit of performance delivered through force induction, the German tuner recommends customers to specify their cars with a 9-way adjustable coil-over sport suspension. 20-inch multi-spoke Silverstone Diamond alloys, wrapped around in 245/30 front and 285/25 rear Michelin tires, can be ordered, too. For a more ferocious roar, G-Power can provide a new, hand-built rear silencer, with matching tail pipes.

Granted, these changes don’t transform the Z4 SK Plus into a Hurricane killer, but the tuner charges only €2.500 (VAT excluded) for the performance upgrade, which as we mentioned previously, is also available for the E46 BMW 3 Series.

G-POWER X5 M and X6 M TYPHOON with 600hp

G-POWER's a well known BMW has released performance and equipment package for the new BMW X5 M and BMW X6 M. The aerodynamic kit is largely derived from the G-POWER Widebody-Kit TYPHOON.

Both SUVs feature a full carbon fibre front skirt with striking air inlets, a bonnet made of Kevlar hybrid or carbon fibre, and wide carbon fibre side skirts. A rear diffuser compliments the bragging four tailpipes. G-POWER says they emit a powerful deeptone sound. The X5 M is fitted with one-piece aluminium wheels measuring 11x23 and 12x23 inches while the X6 M's three-piece versions also have the same dimensions. Additionally the X6 M can be had with 22-inch wheels. Tyres are 315/25 ZR 23 high performance Michelins. The suspension systems can be lowered by 30mm.



The twin turbo engines were boosted from 408kW (550hp) to 441kW (600hp) at 6,000rpm and peak torque is 700Nm at 2,000rpm. Acceleration from 0 - 100km/h (62mph) happens in 4.5 seconds, 0 - 200km/h (124.2mph) in 16.2 seconds and top speed is beyond 300km/h (186.4mph).

Interior enhancements include a sports steering wheel, a G-POWER design speedometer, carbon fibre inserts and more.

Lumma Design + G-Power BMW 5 series CLS 730 RS

Lumma Design, a well known German tuner has released a new performance tuning package for the BMW M5 E60. Winterlingen-based Lumma Design has been working with the engineers at G-Power on an upgrade kit to the M-badged version of the 5-series.

The result is a car that uses all 730 horsepower of a bi-compressor V10 to reach a maximum speed of over 367 km/h (228 mph). The 700 Nm of torque helps the car go 0-100 km/h time in 4.2 seconds, reaching 200 km/h in just ten seconds. 300 km/h is achieved in 29.5 seconds.



The companies claim this is the "most powerful engine" ever seen on a "road-legal BMW." It is certainly a huge development over Lumma's CLR 500 RS released in 2007. That car saw a "paltry" 560 horsepower.

Certainly, these figures require non-stock brakes. Lumma Design's own six-piston front, four-piston rear caliper brakes are used along with drilled 405mm discs. Ultralight, three-piece forged 10x21 and 12Jx21 wheels at the nose and tail look great on the 45mm lowered car.

The design package includes carbon fiber boot and bonnet, and the material is also used for the door handles, entrance sills, fenders, and mirror caps. Designers also replaced the exhaust system. Inside, carbon fiber, leather, and suede is used gratuitously. Hopefully, the color scheme chosen inside is customizable, as something more subtle than the contrasting red, white, dark grey would probably feel more appropriate.
