From the
Fiat 500 Abarth and
Smart ForTwo to the
Lamborghini Gallardo and
Ferrari 599 GTO, no project is too big or too small for Romeo Ferraris. The Italian tuning house's latest project sits somewhere in the middle with a
BMW M5. The result of their efforts is a pair of engine tuning packages for the 4.4-liter twin-turbo V8. The more powerful of the two packs an extra 97 horsepower and 81 lb-ft of torque for final figures of 657 hp and 583 lb-ft, while the less potent ECU tune releases an additional 75hp and 65lb-ft of torque.
