[3] After losing his ministerial positions in the General Election 2010 he decided to devote himself totally towards his motorsports company Drayson Racing Technology.

[10] On 29 June 2007 he also became a Minister of State in the newly created Department for Business, Enterprise and Regulatory Reform, combining this with his role in the Ministry of Defence.

His official reason for stepping down was his wish to participate in the Le Mans race, but it has been reported that the actual reasons were being left out of the loop when Prime Minister Gordon Brown decided to disband the Defence Export Services Organisation and equipment budget deficits which would make the follow-up to the DIS largely irrelevant.

[15] In April 2022 Drayson was ousted as chief executive,[16] shortly after the company's financial report claimed that it would run out of money by February 2022.

[18] They have five children, and live between homes in London and Nether Lypiatt Manor near Stroud in Gloucestershire, purchased for £5.75 million in 2006 from Prince and Princess Michael of Kent.

[12] Drayson was born blind in one eye which, under FIA rules, prevented him from acquiring an international racing licence for participation in the Le Mans 24 Hours.

In light of his performance during the 2008 ALMS season and FIA rule changes, he was granted an international licence to allow him the chance of competing in the 2009 24 Hours of Le Mans.

Drayson has currently competed in two seasons of the ALMS with a best finish of a win at the 2010 Road America race in a LMP Lola B09/60.
