With which team did Lewis Hamilton begin his formula one career?

Lewis Carl Davidson Hamilton (born 7 January 1985) is a British Formula One racing driver from England, currently racing for the Mercedes AMG Petronas team. A three-time Formula One World Champion, he is regarded by fellow and former drivers as one of the greatest Formula One drivers in the history of the sport. He won his first title with McLaren in 2008 before moving to Mercedes, where he won back-to-back titles in 2014 and 2015.

It was announced prior to the start of the 2007 season that Hamilton would be partnering defending double World Champion Fernando Alonso who had joined McLaren after leaving Renault. On his debut at the Australian Grand Prix, he finished third in the race, becoming the thirteenth driver to finish on the podium in his first F1 career race (excluding those in the first ever World Championship round). In Bahrain and Barcelona, Hamilton finished second behind Felipe Massa to take the lead in the drivers championship. This meant that Hamilton broke Bruce McLaren's record of being the youngest driver to ever lead the world championship.
