1974 Chevron B26

I took this photograph during the Saturday practice and qualifying sessions of the Gold Cup meeting at Oulton Park in August 2018.

It's John Burton in his 1974 Chevron B26 at Lodge Corner during the qualifying session for the HSCC Pre,80 Endurance Challenge race. The B26 was a replacement for the B23, and as well as revised suspension and a rear wing it had an aluminium monocoque tub instead of the spaceframe chassis of all the earlier Chevron sports racing cars. It had a 4-cylinder inline 1,998 Ford engine with an aluminium block, which had been designed by Brian Hart and re-engineered by Cosworth. Only 9 of these cars were made, mainly due to lack of demand because of the 1973 oil crisis in the UK.
