Back in 2012G-Power unveiled the BMW M5 Hurricane RRS, which delivered an amazing output of 830 horsepower. Now, the tuner used the experience accumulated developing that car and created the M3 GT2 R, which is not only the baddest road-legal M3 around, but also a sort of tribute to the M3 GT2, which raced in numerous GT events between 2009 and 2013.

A base BMW M3 delivers a total of 420 horsepower, but with some intensive work, the guys over G-Power managed to add another 300 horsepower to the car’s V-8 engine, transforming the M3 Coupe into a real monster. Most likely, this will be one of the latest staggering upgrade kits offered for the M3 before it goes out of production in September.

Along with the amazing job done under the hood, G-Power also offers a modified aerodynamic package made entirely in carbon fiber to help increase downforce and save some weight.

For the interior, G-Power installs carbon-fiber racing front bucket seats and eliminates the rear ones altogether. G-Power then trims the interior in its in-house leather package that features numerous leather and Alcantara elements with blue contrast stitching.

G-Power also adds an element of safety by installing a roll cage, which also increases the rigidity of the body.

As no surprise to anyone, G-Power will spend plenty of time under the hood of your M3. In here, the tuner starts by adding a G-Power M3 "Sporty Drive" supercharger system that includes an ASA Centrifugal Supercharger. To go along with the boost, there is also a tailor-made cooling system and a new titanium exhaust system with free-flowing 100 cpsi metallic catalytic converters.

All these changes bumps the M3’s power output to mind-blowing 720 horsepower. When you add a total weight of just 3,300 pounds, you know you’re in for some amazing performance figures. Unfortunately, G-Power is keeping the performance specs a secret, for now...

Suspension and Brakes

On the corners, G-Power adds in a set of 20-inch G-Power Silverstone RS wheels wrapped in Michelin Pilot Cup tires sized 245/30ZR20 on the front axle and 315/25ZR20 for the rear axle.

Bringing this powerful M3 to a stop is no easy task, so G-Power then switches its focus to installing a G-Power ceramic brake system, which features six-piston brake calipers up front with 396 mm (15.6-inch) rotors and four-piston calipers on the rear with 380 mm (15-inch) rotors.

G-Power didn’t ignore the corners, as it also adds in a Clubsport coil-over suspension to keep things tight in the twist.

Press Release

The G-POWER M3 GT2 R is probably the hottest road-legal BMW M3 in the world. It combines 720 supercharged horsepower with a kerb weight of less than 1.500 kg, all wrapped up in an awesome body kit featuring the current GT2 R design. This mix of increased power output and weight reduction is turning the BMW GT2 R into a true Clubsport version of the BMW M3.

Complete car M3 GT2 R: starting from € 195,310.00 Euro (net) The G-POWER M3 GT2 R is a true Clubsport version of the BMW M3 that distinguishes itself by a serious increase in power output and a significant weight reduction, but also with a modified aerodynamic that provides for a maximum of down force. Prepared like this the G- POWER M3 GT2 R is the perfect match for the occasional track day racer, who enjoys the luxury of arriving to the race track on its own wheels without having to accept compromises in regards of performance on the track. Thus the bullet points for the GT2 R project have been set: more than 700 hp power output and less than 1.500 kg kerp weight. The G-POWER GT2 R package therefore covers the mighty SK III “Sporty Drive” supercharger system.

As demonstrated in G-POWER’s supercharger systems for the legendary BMW V10, the full potential of high-revving BMW engines and G-POWER superchargers can only be achieved through significant modification of the base engine. Fortunately, the V8 in the current BMW M3 (E9x) is essentially a „shortened“ version of the BMW V10 engine that G-POWER modified to create its world-record setting, 800hp G-POWER M5 HURRICANE RR. Thus G-POWER is able to leverage the proven forged pistons from that engine and developed through G-POWER’s technology partner MAHLE. These pistons are produced exclusively for G-POWER. The connecting rods also received a birth- by-fire in the engine bays of the countless G-POWER SK III supercharger systems delivered worldwide in BMW M5s and M6s. However, the SK III „Sporty Drive“ supercharger system for the M3 differs from the M5/M6 Supercharger System with an additional highlight in the engine bay. Inspired by the BMW M3 GTS the G-POWER M3 SK III “sporty Drive” Supercharger System includes a modified crankshaft. This new crankshaft increases the displacement of SK III-equipped M3s by approx. 15%, from 4.0L to 4.6L.

The resulting modified V8 then meets the latest evolution of the world’s best-known components of G-POWER M3 „Sporty Drive“ supercharger systems. At its heart is the flagship of the ASA Centrifugal Supercharger product line – the powerful ASA T1-724. A maximum pressure of 0.7 bar can now be achieved and feeds air to the BMW V8’s individual throttle butterflies through the use of the G-POWER airbox. A tailor-made cooling system for the SK III Supercharger System increases the capacity of the oil and water cooling circuits just like the intercooler system of the V8 engine to keep temperatures in check. A titanium exhaust system made specifically for G-POWER ensures that exhaust gases are discharged quickly and with minimum back pressure. This system features free-flowing 100 cpsi metallic catalytic converters.

Already the engine modifications from G-POWER are enough to set the G-POWER Clubsport variant apart from the production standard. A never-ending supply of torque is the name of the game once the forced induction M3 engine stretches its legs out of the mid rev range to storm all the way to the limiter as if fired from a catapult.

At the same time, G-POWER also gets to work on the flab, placing the BMW M3 on a strict weight loss regime. This is where the G-POWER GT2 R comes into its own, with a full carbon body kit bearing the current GT2 R design. The front skirt, all four wings and the rear skirt are all replaced by ultra-lightweight carbon elements. A carbon front lip and the multi-part carbon rear spoiler also improve aerodynamic down force.

The carbon fiber G-POWER hood also contributes to reduced weight. The starting point for the development of the G-POWER hood was the technical necessity to remove heat from the engine compartment of the uprated engines as quickly as possible. Otherwise a loss of performance can happen, since the ECU (electronic control unite) makes use of diagrams with reduced degrees of ignition when a fixed temperature limit is reached, in order to safeguard the engine. The "DYNAMIC VENTING" Technology of the G-POWER hood vents the engine compartment dynamically, allowing the otherwise untapped performance potential to be achieved with no additional thermal stress. Performance enhancement cannot be supported more efficiently.

When it comes to suspension systems, the G-POWER M3 GT2 R is fitted with the G-POWER CLUBSPORT coil-over suspension and weight-optimized 20-inch G-POWER SILVERSTONE RS forged wheels. The tires are Michelin Pilot Cup tires in the dimension 245/30 ZR 20 on the front axle and 315/25 ZR 20 for the rear axle to keep the vehicle in contact with the road. Braking is done with the G-POWER-ceramic brakes on the front and rear axle, which provide low-weight and reliable high-performance braking. „Fade“ is therefore a foreign word for the 6-piston brake calipers in front which bite on 396 mm rotors and the 4-piston calipers at the rear axle which clamp on 380 mm rotors.

On the inside of the vehicle, G-POWER has swapped the series production front seats for carbon racing buckets that not only support the driver in his battle with centrifugal forces, but are also each 12 kg lighter than their standard counterparts. Just like that, another 24 kg disappear. The G-POWER M3 GT2 S also goes without its rear bench, while the interior is upgraded with an individual G-POWER leather trim package. Leather and Alcantara applications in G-POWER orange with blue stitching give the sporty and spartan interior a touch of class and a luxurious feel. The interior is completed by a roll cage according that meets FIA standards.
