Thank you for the Lock Nicanary. My flight has now safely landed, but I'm not too much the wiser about this car, which seems to be known as the Triumph Racing Car.
It was built c.1990 from the remains of a Triumph GT6 with a 2.5-litre engine, and is co-owned by Yve Rivers-Fletcher, who I think may be driving the car. It has competed at many circuits and hillclimbs in the UK, including wins this year (2016) as Prescott and Wiscombe. Does this help?
