G-Power offers their own tuning kit for the BMW 1M, along with some visual upgrades. First and foremost, the 1M sheds some weight with the use of a new exhaust system made out of titanium and which weighs 20 percent less than the standard one. To increase the power output, the G-Power engineers have also included flow-optimized downpipes for lowering exhaust gas temperature, a larger cooling system, and new ECU mapping.

The result is a significant increase in power, from the standard 340 hp (253 kW / 344 PS) to 435 hp (324 kW / 441 PS), and from 368 lb-ft (500 Nm) to 435 lb-ft (590 Nm) of torque.

Thanks to these upgrades, the G-Power 1M can run from 0 to 62 mph (0-100 km/h) in 4.5 seconds. The top speed was also raised to 186 mph (300 km/h).

All this power needs a great braking system, an option included by G-Brake, with six brake pistons and up to 396 mm brake disc diameter.  The sporty 1M also rides on 20-inch G-Power Silverstone alloys with Michelin tires.

Here is the full press release below.

Press Release

It is not just the „M” in the name of the BMW 1M Coupé that identifies it as a member of the “M-Family” it is the design, as well. The BMW 1M Coupé is closely related to its bigger brother the BMW M3 with which it shares the same front and real axles. Unfortunately when it comes to the power output figures the BMW 1M Coupé does not play in the same league with the rest of the family. Help is coming from G-POWER with its latest package for the youngest member of the M-Family.

The G-POWER program for the BMW 1M Coupé covers all key components that let it join up with the other M-Models. Thereby the G-POWER engineering department has used the know-how gained from the development of the G-POWER supercharger systems on the BMW 3.0l straight six cylinder engine. After all the ASA supercharger used by G-POWER for its supercharger systems is conceptual closely related to the turbocharger used by BMW, since both variants use a centrifugal compressor to build up boost.

Based on this know-how G-POWER has put together a performance package for the BMW 1M Coupé, which goes well beyond all electronic performance output enhancements available on the market, and covers hardware components that are directly and indirectly related to the forced induction. It starts with flow optimized downpipes to reduce the exhaust gas temperature and an enlarged capacity for the boost cooling system so that the operating temperature of the engine is kept at an output optimal level under all circumstances.

Exhaust sides a complete exhaust system made from Titanium with 4 Carbon or Titanium tail pipes provides for a sporty sound, which can be enhanced up to racing level by a wireless control switch. At the same time the use of the ultra light material Titanium enables a weight reduction compared to the stock exhaust system by approx. 20 kg.

The G-POWER power output enhancement is completed by a custom-made engine software that, taking into account the hardware modifications and the individual product variance, defines new parameters for the fuel amount and ignition timing; in addition the boost level is slightly raised.

All the G-POWER engine modifications for the BMW 1M Coupé add up to a power output enhancement from 340 hp / 500 Nm to 435 hp / 590 Nm. So the G-POWER 1M Coupé surpasses its bigger brother the M3 by 15 hp and a giant 195 Nm of torque. Prepared like this the G-POWER 1M Coupé propels itself from stand still to 100 km/h in just 4.5 seconds and the top speed is reached at 300 km/h.

Concerning the suspension at first one will notice the 20 inch G-POWER SILVERSTONE SILVERSTONE wheels, wrapped with tyres from the G-POWER’s technology partner MICHELIN in the dimensions 255/30 ZR 20 and 295/25 ZR 20. The double spokes, typical for the G-POWER design, highlight the spectacular design of the BMW 1M Coupé. Further improvement of the road handling is realized through the continuously height-adjustable G-POWER coil-over suspension GM1-RS with nine selectable settings each for bound and rebound.

Of course the negative acceleration is in the focus of G-POWER, as well. The perfect cure against the fading effect is a G-POWER Braking System. With its up to six brake pistons and up to 396 mm brake disc diameter, 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. In addition the G-POWER ceramic braking system reduces the unsprung mass by 50% percent, compared to a system with steel brake discs. Accordingly the cornering and road handling is improved significantly.
