Ferrari F430 Spider Sports Cars

As part of Ferrari's 60th Anniversary Celebrations, researchers at Maranello have developed an engine powered by the bio-fuel E85 for the F430 Spider.
The Ferrari F430 Spider Bio-fuel uses an 85% ethanol mix which was made possible with modifications made to the fuel feed system and to the engine CPU. The combined use of this type of bio-fuel and the modifications made resulted in a power hike of 10hp at the same rpm and a 4% increase in torque yet retaining overall weight.
