Anthony Denis Davidson (born 18 April, 1979 in Hemel Hempstead, Hertfordshire, England) is a British Formula One racing driver from England. He has raced for Minardi, Super Aguri and been a test driver for the British American Racing and Honda teams. He is currently a test driver for Honda.
In 2001, Davidson competed in the British Formula Three championship with the Carlin team, finishing second overall to teammate Takuma Sato. His performance improved throughout the season and he outscored Sato from June until the season's end. He also won the Formula Three Pau Grand Prix, the Spa Masters and the FIA European Cup.
He was not given a chance to race in 2003 and remained as test driver at BAR alongside Takuma Sato. When Sato was promoted to the race team following the departure of Jacques Villeneuve, it presented Davidson with the opportunity to become third driver. This was especially useful in 2004 as BAR were able to run a third car in Friday morning testing, which became Davidson's duty. He frequently impressed with his pace, although some have questioned the validity of these times as a raw indicator due to the lack of need to conserve the car in the way race drivers Sato and Jenson Button did.
In November 2004, BAR announced that it had failed to come to an acceptable contractual agreement with the Williams team to allow Davidson to drive for Williams in 2005 because Williams would not agree to his unconditional "repatriation" to BAR in 2006. Given BAR's long-term contract on Davidson, his chance of securing a race seat for 2005 was therefore called into serious doubt. He was given the opportunity to fill in for an unwell Sato at the 2005 Malaysian Grand Prix, but his engine expired just two laps into the event.
In 2006 Davidson resumed his role as test driver for BAR, now owned by Honda and renamed Honda Racing F1. As BAR had failed to be one of the top four constructors the previous season Honda were able to run a third car on Friday, giving Davidson a bigger role than in 2005. Having previously done some radio commentary work for BBC Radio 5 Live, in 2006 he made his debut as a television commentator, standing in for the absent Martin Brundle for ITV Sport at the Hungarian Grand Prix, which was won by Jenson Button and the Honda team. In 2008 Davidson returned to Honda as test driver for the testing at Spain's Circuit de Catalunya whilst Honda test driver Alexander Wurz was racing at Le Mans.
On 15 November 2006, Super Aguri confirmed that Davidson would partner Takuma Sato for the 2007 Formula One season. Thus, he became a regular Formula One driver for the first time.
At the 2007 Canadian Grand Prix Davidson was running third when his car struck a groundhog on the straight before the pits, ultimately putting him back to 11th place and ending his bid for his first career points. At the Hungarian Grand Prix Davidson's rear suspension was broken during a collision with Giancarlo Fisichella, which forced him to retire. Davidson finished the season in 23rd place having scored no points.
Amid financial problems which threatened their continued participation in Formula One, Super Aguri retained Davidson alongside team-mate Sato for . However, on May 6 2008 Super Aguri withdrew from the Championship leaving Davidson without a race seat. He has since been heard as a co-commentator on selected Grands Prix for BBC Radio 5 Live.
