Driving at the very limit of a vehicle's capabilities is daunting at the best of times but when you place said vehicle on a sprint course that measures little wider than the wheel arches and sports hazards such a dry stone walls and bridges, the fear factor is cranked up a notch.
Multiple A1GP winner and all-round racing maestro Robbie Kerr took adrenaline levels to unhealthy heights at the Cholmondeley Pageant of Power this weekend when he smashed the sprint course record in his 2013 Radical SR8 RX.
The ultra-lightweight two-seater can rocket to 60mph from a standstill in just 2.7 seconds and can produce up to 2.5 G's worth of cornering force when in full swing. When combined with a handy driver, the result is a course time of just 55.29 seconds - that's 7 seconds faster than a Lamborghini Gallardo Superleggera LP570-4 piloted by Nikki Faulkner.
The video below was captured thanks to a camera mounted just behind Robbie's head and it brilliantly portrays the skill and resolve needed to tackle a sprint course at record-breaking speed.
Robbie, you are a brave man and we salute you
