Kart racing or karting is a variant of open-wheel motorsport with small, open, four-wheeled vehicles called karts, go-karts, or gearbox/shifter karts depending on the design. They are usually raced on scaled-down circuits. Karting is commonly perceived as the stepping stone to the higher and more expensive ranks of motorsports.

Karts vary widely in speed and some (known as Superkarts) can reach speeds exceeding 160 miles per hour (260 km/h), while go-karts intended for the general public in amusement parks may be limited to speeds of no more than 15 miles per hour (24 km/h). A KF1 kart, with a 125 cc 2-stroke engine and an overall weight including the driver of 150 kilograms has a top speed of 85 miles per hour (137 km/h). It takes a little more than 3 seconds to go from 0 to 60 mph with a 125 cc shifter kart (6 gears), with a top speed of 115 miles per hour (185 km/h) on long circuits.

Art Ingels is generally accepted to be the father of karting. A veteran hot rodder and a race car builder at Kurtis Kraft, he built the first kart in Southern California in 1956. Karting has rapidly spread to other countries, and currently has a large following in Europe.

Lewis Carl Davidson Hamilton,MBE (born 7 January 1985) is a British Formula One racing driver from England, currently racing for the McLaren team. He is the 2008 Formula One World Champion.

Hamilton was born in Stevenage, Hertfordshire. In December 1995, at the age of ten, he approached McLaren team principal Ron Dennis at the Autosport Awards ceremony and told him, "I want to race for you one day ... I want to race for McLaren." Less than three years later McLaren and Mercedes-Benz signed him to their Young Driver Support Programme. After winning the British Formula Renault, Formula Three Euroseries, and GP2 championships on his way up the racing career ladder, he drove for McLaren in 2007, making his Formula One debut 12 years after his initial encounter with Dennis. Lewis Hamilton's contract for the McLaren driver development program made him the youngest ever driver to secure a contract which later resulted in an F1 drive.

Coming from a mixed-race background, with a black father and white mother, Hamilton is often labelled "the first black driver in Formula One", although Willy T. Ribbs tested an F1 car in 1986. He is also the first driver of black heritage to win a major race at Indianapolis Motor Speedway in any discipline.

Michael Schumacher (German pronunciation: [ˈmɪçaʔeːl ˈʃuːmaxɐ] ( listen); born 3 January 1969) is a German Formula One racing driver for the Mercedes team. Schumacher is a seven-time World Champion and is widely regarded as one of the greatest F1 drivers of all time. He holds many of the formula's driver records, including most championships, race victories, fastest laps, pole positions, points scored and most races won in a single season – 13 in 2004. In 2002 he became the only driver in Formula One history to finish in the top three in every race of a season and then also broke the record for most consecutive podium finishes. According to the official Formula One website he is "statistically the greatest driver the sport has ever seen".

After beginning with karting, Schumacher won German drivers' championships in Formula König and Formula Three before joining Mercedes in the World Sportscar Championship. After one Mercedes-funded race for the Jordan Formula One team Schumacher signed as a driver for the Benetton Formula One team in 1991. After winning consecutive championships with Benetton in 1994/5, Schumacher moved to Ferrari in 1996 and won another five consecutive drivers' titles with them from 2000 to 2004. Schumacher retired from Formula One driving in 2006 staying with Ferrari as an advisor. Schumacher agreed to return for Ferrari part-way through 2009, as cover for the badly injured Felipe Massa, but was prevented by a neck injury. He later signed a three-year contract to drive for the new Mercedes GP team starting in 2010.
