The Caterham 21 was, to put it simply, a rebodied Caterham 7.
Under the curvaceous body designed by Iain Robertson lay a slightly
altered 7 chassis.
With the Caterham 21, Caterham were able to offer a much more
practical sports car without sacrificing the dynamic abilities
inherent to the 7, and in fact, due to the improved aerodynamics,
the Caterham 21 was faster.
Under the fibreglass body of the Caterham 21 was either a 1.6
Rover K-series engine of a more potent 1.8 litre engine from
the MG F.
In total just under 50 Caterham 21 sports cars were manufactured.
