Amidst financial troubles, Super Aguri withdrew from the sport after the 2008 Spanish Grand Prix, ending both Davidson and Sato's driving careers in Formula One.

Following his departure, Davidson moved into sportscar racing, competing in the premier LMP1 class of the FIA World Endurance Championship from 2012 to 2017 with Toyota, winning the series in 2014 alongside Sébastien Buemi.

Born in Hemel Hempstead, Hertfordshire, Davidson began kart racing in 1987, competing in various British, European and North American championships.

[citation needed] Given BAR's long-term contract on Davidson, his chance of securing a race seat for 2005 was therefore called into serious doubt.

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.

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.

Amid financial problems which threatened their continued participation in Formula One, Super Aguri retained Davidson alongside teammate Sato for 2008.

He returned in the 2010 edition, driving for defending champions Team Peugeot Total alongside Alexander Wurz and Marc Gené.

Following Le Mans, Davidson raced at the 2010 6 Hours of Silverstone with Nicolas Minassian and secured victory for Peugeot Sport.

In October 2010, Davidson secured pole position at Petit Le Mans, and went on to finish second with teammates Alex Wurz and Marc Gené.

[10] Five hours into the race,[11] as Davidson was lapping the AF Corse Ferrari 458 Italia GTC of Piergiuseppe Perazzini, the two cars collided at the end of the Mulsanne Straight.

The collision turned Davidson's car sideways before becoming airborne, flipping through the air, before landing back on its 3 remaining wheels before making heavy contact with the barriers.

[12] Davidson got out of his car before calling for assistance; he was later transferred to hospital where he was later diagnosed with fractures to the eleventh and twelfth thoracic vertebrae of his back.

During the year he won four races and finished third in the 2014 24 Hours of Le Mans, and became 2014 World Endurance Drivers' Champion alongside co-driver Sébastien Buemi.

The 2017 FIA World Endurance Championship season showed an improvement in form, and Davidson and his co-drivers took five victories and one further podium finish for the Toyota team during the campaign.

Despite his 2017 performance, Davidson was the crew member of the number 8 Toyota entry who was moved aside to allow Fernando Alonso to contest the 2018–19 FIA World Endurance Championship.

Toyota switched Davidson backward into a test and reserve role, and he did not compete in the first two races of the 'superseason', including the 2018 24 Hours of Le Mans.

[16] On 7 December 2011, Sky Sports announced that Davidson would join its British team as an analyst for race weekends, and would be commentating on practice sessions from the 2012 season.
