Last year, a Caterham SP/300.R became the fastest car at the Cholmondeley Pageant of Power with a lap time of 61.89 seconds. The Caterham did all it could to defend its title this year, but a Radical SR8 RX turned out to be the fastest car this year.

With professional racecar driver, Robbie Kerr, behind the wheel, the British-built Radical completed a lap of the 1.2-mile circuit in just 55.29 second, smashing the previous record by 6.6 seconds. The SP/300.R was the second fastest car with a lap time of 56.53 seconds. The Radical didn’t end its supremacy there, as it also hit the fastest speed on the track: 129 mph.

The SR8 RX was entered in the "Racing Saloons & Track Day Cars" class, which helped it break the record, due to the track-focused nature of the cars competing in that class. The competition saw a total entry of 139 cars and bikes.
