Monza, throughout its long and storied history has been known for its high-speed, simplistic nature thanks to its 1920's design and the few alterations it has received, and is currently the fastest track on the Formula One calendar and has been so since 1991. Monza consists of very long straights and tight chicanes, putting a premium on good braking stability and traction. The circuit is very hard on engines- Formula 1 engines are at full throttle for nearly 80% of the lap, with engine failures common, notably Fernando Alonso in the 2006 Italian Grand Prix.
