G-Power BMW M3 E46 2012 Review

The M3 E46 debuted in October 2000 and is now considered a classic BMW. At the time it was introduced on the market, the engine found under its bonnet was the most powerful naturally aspired BMW engine, thus the M3 E46 became an icon in the automotive world. If you find the M3 E46 appealing but fear that it's not powerful enough in our days then don't worry because G Power now paid homage to the M3 E46 and revealed their latest tuning kit which makes the old E46 more powerful than the E90.

The M3 3.2 liter six-cylinder engine found in the G Power BMW M3 E46 2012 got a 106 HP and 70 lb-ft of torque increase thanks to an ASA T1-518 centrifugal supercharger. The 3.2 liter unit is now able to produce 444 horsepower and 339 lb-ft of torque, making the G Power go from 0 to 124 mph in 14.7 seconds. Furthermore the G Power M3 is now able to reach a top speed of 186 mph, 31 more than the standard M3 E46.

To cope with the raw power the tuning package includes upgraded brakes featuring 370 mm disks at the front, 342 mm disks at the rear and six-piston calipers.

Furthermore the G Power tuning package also include a set of 20-inch alloy wheels with 245/30, 285/25 Michelin Pilot Sport tires, adjustable coil-over suspension and a beefier exhaust system.

As far as pricing goes the G Power tuning package will set you back $9,280 (€7,000) for the performance upgrades, $5,862 (€4,422) for the new rims and Michelin Pilot Sport tires, $7,689 (€5800) for the front brakes and $5,117 (€3,860) for the rear brakes, bringing the entire tuning package to a total of $27,950 (€21.082).

So, there you have it. The G Power BMW M3 E46 2012 is basically more powerful than theM3 E90 which delivers 414 HP, 295 lb-ft of torque and a top speed of 155 mph.

In case you were excited by the limited edition E92 M3 GTS which boasted 444 horsepower and you were not able to get your hands on one of the 250 units produced (and already sold out), then G Power now gives you the chance to own a classical M3 alternative that interesting enough, produces the same amount of power as the 2009 limited edition.

G-POWER M3 E46 with 450 hp – Now the “old M3” is quicker than the “new M3” 


450 hp for the BMW M3 E46, that’s quiet impressive. The G-POWER SK I „SPORTY DRIVE“ supercharger system provides the 3.2 l straight cylinder engine from the BMW M GmbH with the necessary boost to push the output from standard 343 hp/365 Nm to awesome 450 hp/460 Nm. 20 inch G-POWER “SILVERSTONE DIAMOND” alloy wheels with MICHELIN Pilot Sport tyres in the dimensions 245/30 ZR 20 and 285/25 ZR 20, G-POWER coil-over suspension, G-POWER braking system and a stainless steel sport rear muffler featuring the legendary G-POWER “DEEPTONE” technology complete the G-POWER package for the BMW M3 E46.


  • 450 hp / 331 kW at 7.000 rpm (+ 107 hp / 79 kW)
  • 460 Nm at 5.500 rpm (+ 95 Nm)
  • V-max: 300 km/h
  • 0-200 km/h: 14,7s
  • G-POWER stainless steel rear muffler
  • G-POWER coil-over suspension GM3-RS
  • G-POWER Braking System for front and rear axle 

After getting the BMW E46 scene ecstatic with the 550 PS strong G-POWER M3 with integrated 5.0l M5 V10 engine, by the way the only one on the market, G-POWER launches another product for serious performance upgrade for the BMW M3 E46, that will fascinate the M- enthusiasts.  Being the leading manufacturer of after market supercharger systems for BMW automobiles it is no surprise that G-POWER naturally relies on forced induction for its new product based on the premium superchargers from ASA.    

And the result is awesome! Despite the fact that G-POWER did not go for the expensive compression reducing forged pistons and even the exhaust system stays untouched, reliable 450 hp and 460 Nm of torque could be realized for the BMW M3 E46.

The secret behind this power explosion under the bonnet of the G-POWER M3 E46 is the large ASA T1-518 centrifugal supercharger. By the way, the ASA superchargers are being used in the ALPINA models B5S, B6S and B7 as well, just like the ALPINA B6 GT3 race car, in witch the chargers could state there impressive quality and reliability during several 24th hour race in the “Green Hell” of the Nürburgring! The exclusive use of components meeting OEM standards is one of the basic elements of the G-POWER philosophy and one of the secrets for the extraordinary quality, reliability and performance of the G-POWER products.

Of course a 107 hp additional power leave its marks at the performance figures. The figure from stand still to 200 km/h improves from standard 18,1 seconds to impressive 14,7 seconds. Not bad for a car that has been introduced almost 10 years ago and now is even quicker than the current 420 hp strong BMW M3 V8 with its 15,8 seconds.

Accompanying measures in regards of wheels, suspension, brakes and exhaust system complete the G-POWER program for the BMW M3 E46.

Together with the 20 inch G-POWER “SILVERSTONE DIAMOND” alloy wheels set and the MICHELIN Pilot Sport tyres a top speed of more than 300 km/h is achievable. The G-POWER SILVERSTONE alloy wheels have been exclusively designed for the current BMW models. Due to the successful combination of double spokes and the "concave design" typical of G-POWER they separate the BMW M3 E46 form the rest of the mass production. The G-POWER “diamond cut” provides for the fascinating dynamic appearance of the G-POWER SILVESTONE rim, in contrast to the silver-graphite coated rim body and the bolt applications of stainless steel. An additional feature of the G-POWER SILVERSTONE rim is its weight-optimised design that allows a low rim weight with the same stability, compared to other standard wheels. A perceptibly improved impression of convenience and a considerably increased agility accompany the minimisation of the unsprung mass: advantages of the G-POWER SILVERSTONE rim, which you can factually experience especially in combination with the low-profile tyres from MICHELIN in the dimension 245/30 ZR 20 and 285/25 ZR 20. Further improvement of the road handling is realized through the continuously height-adjustable G-POWER coil-over suspension RS with nine selectable settings each for bound and rebound.

Of course the negative acceleration is in the focus of G-POWER, as well. Even without output increase, the standard braking system may lose brake force when pushed to the limit, accompanied by a moving braking point, the so called fading effect.  The perfect cure against the fading effect is a G-POWER Braking System. With its up to six brake pistons and up to 370 mm brake disc diameter for the front axle and 342 mm for the rear axle, the G-POWER Braking System enables a substantially higher brake force than the standard braking system. At the same time, the heat generated due to the braking process can be dissipated more effectively. The G-POWER brake package is completed by brake pads with a larger pad area, higher friction rate as well as metal-coated brake lines. With this set-up, the G-POWER Braking System always provides maximum brake force and the braking point remains precise in any case.

Not included in the G-POWER SK I „SPORTY DRIVE“ supercharger system for the BMW E46 M3, but still worth a second thought, is the G-POWER sports rear muffler. This rear muffler is completely hand made out of stainless steel on the in- and outside and grants for a perfect fit thanks to OEM standard product quality. Though when you fire up the engine and the throaty G-POWER sound emerges the 4 x 76 mm end pipes of the G-POWER sports rear muffler, all those attributes are swept aside. The sound is strong in low revs and is getting more and more aggressive the higher you rev. With this setup the G-POWER sports rear muffler underlines perfectly the significantly increased power of the BMW M3 E46.  The patented G-POWER “DEEPTONE” technology is responsible for this extraordinary sound pattern.

The cost for the 20 inch G-POWER SILVERSTONE DIAMOND complete wheel set incl. MICHELIN Pilot Sport tyres in the dimension 245/30 ZR 20 and 285/25 ZR 20 is 4.422,17 €, the G-POWER coil-over suspension RS is 1.205,88 € and the G-POWER sport rear muffler is 1.079,83 €. The G-POWER braking system for the front axle is 5.800,00 € and 3.860,00 € for the rear axle. The output increase with the help of the G-POWER SK I „SPORTY DRIVE“ supercharger system for BMW M3 E46 and Z4M is 7.000,00 € plus the installation.

Since the company’s founding in 1983, it has focused solely on the tuning of BMW cars and the production of exclusive, handcrafted vehicles. In 2008, G-POWER was integrated into Group ASA, a year in which both brands celebrated their 25th anniversary. G-POWER is now one of the few globally active and highly reputable suppliers of exclusive cars. In cooperation with development partner ASA, G-POWER has developed unique versions of BMW’s most important models, and the world's most powerful versions of each, which clearly sets us apart from our competitors.
