According to the executive, Ferrari had prior experience with e85 in Formula one racing. When racing, Formula One has regulations that say all the cars used in races must use fuel that is comprised of 5.75 percent biomass.On the other hand, The FIA GT and the American Le Mans racing series have somewhat stricter policies. Those races require drivers to use race car's that operate with e10 or ten percent ethanol.In order for Ferrari to create the F430 Spider Bio-fuel, Ferrari engineers had to do some minor tweaks to the car's engine. The engineers had to make changes to the fuel injection system and they had to change settings in the Ferrari's engine computer. This resulted in lower carbon dioxide emissions - a five percent cut - and as an added bonus, it also increased the car's power output with no changes to the car's weight.
