The co-founder of World Touring Car and World Endurance Championship outfit Bamboo Engineering, Nigel Vaulkhard, has died after a mountain biking accident.
Vaulkhard, father of former British Touring Car and WTCC racer Harry, was airlifted to hospital after the incident on Wednesday but later passed away from the injuries he sustained.
The 66-year-old, a former Porsche Carrera Cup GB and European Historic Touring Car racer, set up Bamboo in 2009 with Richard Coleman.
It ran James Nash to third in the WTCC last season before pulling out of the tin-top series to concentrate on an affiliated WEC effort with Asian squad Craft Racing.
Craft-Bamboo confirmed its Aston Martin Racing-entered trio of Alex MacDowall, Darryl O'Young and Fernando Rees will continue to compete in the WEC round at Spa this weekend, while Coleman paid tribute to his former co-owner.
"Nigel and I started working together in late 2008 and since then became very close friends," he said.
"Nigel co-founded Bamboo and was a driving force in the team - his passion, commitment and belief in the team was unparalleled."
