All of these tyres offer different performance characteristics relevant to the vehicle they are designed for but in these cases they focus particularly on environmental performance, in addition to safety, handling precision, comfort and longevity. This performance is clearly shown by the Pilot Sport Cup 2 tyres fitted to the 918 Spyder as they reduce rolling resistance to help conserve battery life and reduce CO2 emissions in addition to offering excellent grip and handling at very high speed, as demonstrated by the world record lap time set at the Nurburgring. This ability to offer different performance characteristics in the same tyre is known as Michelin Total Performance.
