The German tuner G-Power has unveiled yet another tuning kit for BMW M3. Called "Sporty Drive," this new version adds up to 25 percent more power for the car’s V-8 engine and it can be combined with updated suspensions and, of course, a new set of wheels.
The new "Sporty Drive" system is being offered in three versions: SK I, SK II and SK II CS, with the latest one adding up to 190 horsepower to the car’s standard 420 horsepower. All versions include a TU (Technical Update) supercharger system with modified air intake housing, a larger racing air filter and modified ECU software.
On the exterior, the changes are being kept to a minimum and they only include a new set of 20-inch wheels plus a new stainless steel rear sport silencer with 4 x 83 mm tail pipes.

Exterior and interior
G-Power announced its new "Sporty Drive" package will mainly focus on the car’s engine upgrade, but we are pretty sure customers can also improve the look of their M3. For now, the only update announced by the tuner includes a set of 20-inch wrapped in Michelin tires measuring 255/30ZR20 on the front and 295/25ZR20 on the rear.
The new wheels can be combined with a new "GM3-RS" coil-over suspension with 9-way adjustable compression and rebound that improves directional stability at top speed, as well as help it hug corners more effectively. The backside of the M3 has is equipped with a new stainless-steel G-POWER rear sport silencer with 4 x 83 mm (0.15 x 3.26 inch) tail pipes.
G-Power didn’t announce any upgrades to the M3’s interior.
While the exterior and the interior upgrades are not necessarily impressive, the most incredible changes are under the hood. These drivetrain upgrades come in three different stages: SK I, SK II and SK II CS.
The three stages are offered with a TU (Technical Update) supercharger system and include different upgrades depending on the version. In SK I, the ASA T1-522 supercharger includes extensive CAD engineering and completely redesigned air intakes featuring a larger racing air filter. SK I bumps the M3’s engine up to a respectable 520 horsepower.
The next two versions – SK II and SK II CS – include a new ASA T1-523 supercharger, featuring an additional fuel pump system and, of course, the modification of the standard ECU software. The SKII upgrade bumps the M3 to 580 horsepower and the SK II CS bumps it to 610 ponies.
Thanks to the new "Sporty Drive" TU supercharger system, the G-Power M3 will deliver extremely sporty throttle response and increased performance numbers. We have yet to receive any final track-performance numbers, but we’re sure we’ll hear them soon.
Prices for the new "Sporty Drive" upgrade package will be announced at a later date.
Of course the "Sporty Drive" is not the first or the last package offered for the BMW M3. In fact, G-Power itself offers lots of other packages for the sporty Bimmer. One of its latest packages increases the M3’s output up to 720 horsepower and significantly improves the car’s performance numbers — 0 to 60 mph in just 3.7 seconds and a top speed of 205 mph.
Three engine upgrade stages
Impressive update numbers
No major exterior upgrades
No prices to speak of
Similar to the BMW AG G-POWER, the number one in supercharging, has performed a complex program for the G-POWER M3 supercharger systems to increase its efficiency. The result shows the long-standing experience and the technical expertise of the G-POWER engineering department. Up to 25 % additional output enhancement (now 100 hp instead of 80 hp output enhancement with M3 SK I “Sporty Drive” supercharger system) have been achieved due to optimization in detail.
G-POWER SK I, SK II and SK II CS „Sporty Drive“ TU supercharger system for BMW M3
• SK I „Sporty Drive“ TU supercharger system with 520 PS
• SK II „Sporty Drive“ TU supercharger system with 580 PS
• SK II CS „Sporty Drive“ TU supercharger system with 610 PS
• Significant output enhancement of up to 190 hp and 190 Nm torque
• Supercharger coming from well-known German brand in OEM quality
• Installation without irremovable modifications to your car
• Up to 25 % additional output enhancement compared to the present supercharger system without surcharge
The “TU” in the name of the G-POWER SK I, SK II and SK II CS supercharger systems is standing for “technical update” and it indicates that the well-known and proven G-POWER M3 supercharger system is now available with a technical optimized 2013 version. The revisions have been made in order to enhance the power output, to simplify the system’s installation and are the results of a continuous quality improvement process.
The product launch has been preceded by extensive CAD engineering, complemented with virtual computational fluid dynamics analysis (CFD analysis) and intensive test driving. All components of the air intake and the fuel supply system have been developed from scratch or extensively revised based on our many years of experience. The modified air intake is now housing a larger racing air filter that provides for an enlarged air mass flow and at the same time is more durable and dust resistant. The additional air mass, that is provided by the new air intake, allows the use of the ASA T1-523 supercharger (SK II and SK II CS) compared to the ASA T1-522 supercharger used until now. Reserved for the SK II CS supercharger system is an additional fuel pump system with ECU for a map controlled activation. Moreover, thanks to the complete redevelopment of the air intake, its overall part count has been optimized, further simplifying the installation of the M3 “Sporty Drive” TU supercharger system. The modification of the standard ECU software to the new parameters of the forced induction has been completely reworked and optimized in the course of the upgrade process and is now based on the latest software version of BMW.
In the end the output is now increased between an additional 10 to 20 hp compared to the existing output enhancement. So that now the entry into the world of G-POWER supercharger systems starts with the SK I “Sporty Drive” TU system and 520 hp, followed by the SK II “Sporty Drive” TU system with 580 hp and the SK II CS “Sporty Drive” TU with 610 hp peak performance.
More important to the customer than the naked figures, however, is the power delivery – i.e. the experience generated by the additional output. The key here is the term “Sporty Drive”. In the specification for every tuning program undertaken by G-POWER, this aspect is afforded the same priority as the target power increase itself.
The very first thing you notice behind the wheel of a BMW M3 with a G-POWER “Sporty Drive” TU supercharger system is the extremely sporty throttle response. Every input from the gas pedal is translated immediately into forward propulsion, without the lag usually associated even with modern turbocharged engines. The driver’s command is proportionally and instantaneously implemented. One further characteristic of mechanical supercharging using the ASA radial supercharger is the outstanding torque in the middle of the rev range, which is particularly impressive during overtaking manoeuvres. This lively response from mid-range revs increases continuously until engine speed peaks, which is also where maximum boost pressure is achieved. The acceleration experience is akin to being fired from a catapult.
In order to ensure that all this extra power is delivered safely to the road, G-POWER recommends a combination of the G-POWER 20-inch SILVERSTONE DIAMOND wheel set with Michelin tyres measuring 255/30 ZR 20 on the front and 295/25 ZR 20 on the rear and the G-POWER “GM3-RS” coil-over suspension with 9-way adjustable compression and rebound. The outcome is higher cornering speeds and improved directional stability at top speed.
Always worthy of consideration is the G-POWER rear sport silencer with 4 x 83 mm tail pipes. This hand-built silencer is made completely inside and out from stainless steel and combines an outstanding fit with OE quality.
