Then we realised Heffner Performance is a totally different kind of performance enhancer and tunes the Audi R8 with the aid of turbocharging. The latest R8 to come from this Sarasota, Florida-based outfit is a twin-turbo V10 version of the R8 with some 735hp on tap.
Power is increased from the standard R8 V10's 525hp, though Heffner has not released any acceleration or top speed statistics. It does say the upgrade is a bolt-on conversion and is covered by a 12-month, 12,000-mile warranty.
No word on price either for the conversion, but don't expect change from $30,000 (about €20,700) for the USA-based upgrade.
