Former Formula 1 world championship runner-up David Coulthard announced today that he will retire from all forms of competitive motor sport after the conclusion of the German touring car championship (DTM) this weekend.

The Scotsman, best known for his partnership with Mika Hakkinen at McLaren, was quoted on motorsport website Autosport as saying he was retiring to “concentrate on developing my off-track businesses and, of course, spending more time with my family.”

Coulthard raced made his F1 debut in 1994 with Williams F1 when he was drafted to partner 1996 world champion Damon Hill following the death of Ayrton Senna.

He moved to McLaren in 1996 and had his most competitive seasons in F1 in 2000 and 2001 when he scored 21 podiums over 34 races, winning five and finishing runner-up to Michael Schumacher in 2001.

Following the end of his stint with McLaren in 2004 ‘DC’, as he was referred to, raced for four seasons with Red Bull, who made their F1 debut in 2005 and served as test driver for the current world champions in 2009.

At his peak, Coulthard was regarded as a highly skilled development driver who, on his day could go wheel to wheel with the very best. As was evidenced by his duels (and other altercations) with Schumacher during the latter’s Ferrari days (see vids below and enjoy).
