Direct Injection FTW.
Direct Injection allows for higher compression ratio because the injection of the fuel right into the chamber acts as a cooling jet to help eliminate detonation.
CTS's has this same thing.
Imagine if they cranked it up to 12:1 and made it run on 91...there is another 30hp.
Im actually surprised MB does not have a direct injected engine yet?
