The Autodromo Nazionale Monza is a race track located near the town of Monza, north of Milan, in Italy. The circuit's biggest event is the Formula One Italian Grand Prix, having hosted the event since the sport's inception, and is known as the home of the Tifosi, supporters of Italian team Scuderia Ferrari.
Built in the Royal Villa of Monza park in a woodland setting, the site has three tracks – the 5.793 kilometres (3.600 mi) Grand Prix track, the 2.405 kilometres (1.494 mi) Junior track, and a decaying 4.250 kilometres (2.641 mi) high speed track with steep bankings. Major features of the main track include the Curva di Lesmo, the Curva Parabolica, and the Variante Ascari. The high speed curve, Curva Grande, is located after a slow corner, but usually taken flat out by Grand Prix cars.
Drivers are on full throttle for most of the lap due to its long straights and fast corners, and is usually the scenario in which the open-wheeled F1 cars show the raw speed they are capable of (372 kilometres per hour (231 mph) during the V10 engined formula). The circuit is generally flat, but has a gradual gradient from the second Lesmos to the Variante Ascari. Due to the low aerodynamic profile needed, with its resulting low downforce, the grip is very low; understeer is a more serious issues than at other circuits, however, the opposite effect, oversteer, is also present in the second sector, requiring the use of a very distinctive opposite lock technique. Since both maximum power, and minimal drag is the key for speed on the straights, only competitors with enough power at their disposal are able to challenge for the top places.
In addition to Formula One, the circuit hosts an endurance event, the 1000 km Monza, which has been run as part of the World Sportscar Championship and the Le Mans Series. Monza also featured the unique Race of Two Worlds events, which attempted to run Formula One and United States Auto Club National Championship cars against each other, and previously held rounds of Grand Prix motorcycle racing, in the Italian motorcycle Grand Prix. Current major events are races of the World Touring Car Championship and the Superbike World Championship, as well as various local championship races.
