Formula Three

In the five years since Mercedes-Benz began its involvement in Formula Three, it has developed into the formula's most dominant engine supplier. Its engines, which are built and serviced by H.W.A GmbH, have so far contributed to a total of four drivers' and four teams' championship titles in the Formula Three Euroseries and British Formula Three Championship.

The H.W.A Mercedes-AMG M271 was based on a 1.8 litre 4-cylinder from the C-Klasse, bored out to the regulation 2.0 litre capacity.[13] Formula Three engine regulations demand a naturally aspirated, 4-stroke, 4-cylinder, production-based specification, with a capacity of not more than 2000cc.[14] The M271 made its competitive debut in the 2002 German Formula 3 Championship in two of Mücke Motorsport's three Dallara F302 chassis, driven by Markus Winkelhock and Marcel Lasse.[15] Winkelhock achieved Mercedes' first F3 win at the Nürburgring in August 2002.[16]

In 2003, Mercedes expanded its Formula Three program by supplying three teams in the inaugural year of the F3 Euroseries. Its engine powered the seven cars of Mücke Motorsport, Team Kolles, and ASM Formule 3.[17] Speiss-Opel was dominant, thanks in part to Ryan Briscoe and Prema Powerteam, but Mercedes was winning by the eighth round.[18] Its most notable win was provided by Christian Klien at Zandvoort in the non-championship Marlboro Masters.[19]

Between 2004 and 2006, Mercedes-powered cars have dominated the drivers' and teams' championships in the Euroseries, due in part to its close relationship with ASM Formule 3, which is one of France's most successful F3 teams. It has brought drivers' titles for Jamie Green, Lewis Hamilton, and Paul di Resta.[20] 2006 also saw Mercedes' first participation in the British F3 Championship, when it partnered with Räikkönen Robertson Racing, co-owned by Kimi Räikkönen, and two other teams.[21] Double R Racing's lead driver, Mike Conway, dominated the championship.[22] In the 2007 British F3 season, Mercedes now powers the majority of the Championship field.[citation needed]
