G-Power Builds The 650-HP M2 CSL BMW Wouldn't

BMW may have a freshly-launchedM2 Coupeon the market thathas already impressed us, but that hasn't stopped G-Power from handing the outgoing M2 CS a mega upgrade with 650 horsepower, way more torque, and a big wing. The upgrade package is akin to, or perhaps even better than, theM2 CSL that BMW developed but never built.

It's officially called the G-Power G2M CS Bi-Turbo, and it hands the stock M2 CS bumps in power and torque of nearly 50%. The new 650 hp and 590 lb-ft of torque (compared to 444 hp and 406 lb-ft) are brought about by a series of upgrades comprising a new downpipe, GP-660 injectors, the GP-700 turbo upgrade, a crankshaft central screw lock, and a GP Deeptone exhaust system. Tying it all together is the in-house GP-660 performance software.

If that's too much power, G-Power lets owners choose from three lesser packages (562 hp/531 lb-ft, 533 hp/501 lb-ft, or 493 hp/479 lb-ft), all of which are also available on the standard M2 Competition. But why wimp out? On any of the packages, you can tailor certain options, like lifting the speed limiter setting the fuel overrun cut-off, and you can spec CNC-milled charge-air cooler and boost pipes with custom filters.

Perhaps best of all (depending on your taste), G-Power sells the performance upgrade as a standalone kit so you can maintain sleeper status. But, if you like a few tasty visual upgrades, the company will cater to your needs too.

Options include 20-inch Hurrican RR forged wheels (measuring nine and 10.5 inches across, front and rear) and the GP-Dynamic Wing RR seen above. This wing is made from carbon fiber and allegedly aids high-speed stability. You can add further carbon fiber accouterments to the new exhaust system, which is available with woven carbon fiber tips as standard or four forged carbon tips with gold G-Power logos.
