The power upgrade specialists from G Power have got their skilled hands on the first 2012 BMW M5 F10 and are anxious to start working on numerous enhancements which they say will include new wheels, various aerodynamic parts and of-course an increased output.
Based on an initial evaluation G-Power says it has obtain promising results and should be able to make the new M5 F10 deliver around 620 HP through a first stage kit.
This means an increase of 60 HP from the standard 4.4-litre Bi-Turbo V8 which produces 560 horses.
Of course this might sound more than enough, but not for G-Power who says this in only the beginning and fans should look forward to "one of the most spectacular BMW M5s for the season 2012".
G-Power had definitely got our attention so we’ll keep up posed with photos and details once they release the new ‘beast’.
