Although I enjoyed the overall experience, after two days in the standard Audi S5, the S in the name sort of hit me like the bogus R/T badge on a flurry of recent crap-ass Dodges. Far from crap-ass in this case, but still suffering from a lack of cojones. So I called MTM, German Audi tuners extraordinaire, to see what was cooking for the S5. The reply was: the MTM GT S5 Supercharged.
MTM knows that stock Audi Quattros are heavy and need less weight, more grunt, or (preferably) both. Some fundamental chassis touches can also go a long way in corralling the moving mass through and out of curves.
And grunt there is, with the dial turned up to 492 hp at 6800 rpm from the standard 354, courtesy of the engine bay-dominating Opcon supercharger from Sweden pushing 8.7 psi of boost into the 4.2-liter V8. All-important torque also rises to 398 lb-ft peaking at 3800 rpm versus the stock S5's 325 lb-ft, which sweet-spots at 3500. Although weight remains relatively close to the S5's quoted unladen heft of 3,891 pounds, all that ready power and torque brings the 60-mph dash time down from 4.9 seconds to a more serious 4.4 ticks.
