Driving
Open-wheeled racing is among the fastest in the world. Formula 1 cars can reach 360 kilometres per hour (220 mph). At Autodromo Nazionale Monza, Antônio Pizzonia of BMW Williams F1 team recorded a top speed of 369.9 kilometres per hour (229.8 mph) in the 2004 Italian Grand Prix. Since the end of the V10 era in 2006 speeds like this have not been reached, with contemporary machinery reaching around 345 kilometres per hour (214 mph). It is difficult to give precise figures for the absolute top speeds of F1 cars, as the cars do not have speedometers as such and the data is not generally released by teams. The 'speed traps' on fast circuits such as Monza give a good indication, but are not necessarily located at the point on the track where the car is travelling at its fastest. BAR Honda team recorded an average top speed of 400 kilometres per hour (250 mph) in 2006 at Bonneville Salt Flats with unofficial top speed reaching 413 kilometres per hour (257 mph) using modified BAR 007 Formula 1 car. Speeds on ovals can range in constant excess of 210–220 miles per hour (340–350 km/h), and at Indianapolis in excess of 230 miles per hour (370 km/h). In 1996, Paul Tracy recorded a trap speed of 256.948 miles per hour (413.518 km/h) at Michigan International Speedway. In 2000, Gil de Ferran set the one-lap qualifying record of 241.426 miles per hour (388.537 km/h) at California Speedway. Even on tight non-oval street circuits such as the Grand Prix of Toronto, open-wheel Indy Cars attain speeds of 190 miles per hour (310 km/h).
Driving an open-wheel car is substantially different from driving a car with fenders. Virtually all Formula One and Indycar drivers spent some time in various open-wheel categories before joining either top series. Open-wheel vehicles, due to their light weight, aerodynamic capabilities, and powerful engines, are often considered the fastest racing vehicles available and among the most challenging to master. Wheel-to-wheel contact is dangerous, particularly when the forward edge of one tire contacts the rear of another tire: since the treads are moving in opposite directions (one upward, one downward) at the point of contact, both wheels rapidly decelerate, torquing the chassis of both cars and often causing one or both vehicles to be suddenly and powerfully flung upwards (the rear car tends to pitch forward, and the front car tends to pitch back.) An example of this is the 2005 Chicagoland crash of Ryan Briscoe with Alex Barron.
The lower weight of an open-wheel racecar allows for better performance. While the exposure of the wheels to the airstream causes a very high aerodynamic drag at high speeds, it allows improved cooling of the brakes, which is important on road courses with their frequent changes of pace.

Famous quotes containing the word driving:
“On a late-winter evening in 1983, while driving through fog along the Maine coast, recollections of old campfires began to drift into the March mist, and I thought of the Abnaki Indians of the Algonquin tribe who dwelt near Bangor a thousand years ago.”
—Norman Mailer (b. 1923)
“The beast exists because it is stronger than the thing that you call evolution. In it is some force of life, a demon, driving it through millions of centuries. It does not surrender so easily to weaklings like you and me.”
—Martin Berkeley, and Jack Arnold. Lucas (Nestor Paiva)
“The Westerly Wind asserting his sway from the south-west quarter is often like a monarch gone mad, driving forth with wild imprecations the most faithful of his courtiers to shipwreck, disaster, and death.”
—Joseph Conrad (1857–1924)
