Ariel Atom History
History
The Atom began as a Coventry University transport-design student project by Niki Smart, developed with design lecturer Simon Saunders. After established sports-car firms passed on the idea, Saunders set up his own company (Solocrest Ltd, renamed Ariel Motor Company in 1999) to build it. The Atom was launched at the end of 1999, with the first customer cars delivered in 2000.
Its defining feature is an exposed tubular 'exoskeleton' chassis with no conventional bodywork or roof — the structure is the car. Weighing under 500 kg, the Atom trades comfort and weather protection for an extreme power-to-weight ratio, and built its reputation as a road-legal track weapon that could embarrass far more expensive supercars in a straight line.
Over its life the Atom has moved through several generations and engines — from an early Rover K-series four to a long run of Honda Civic Type R-derived units, supercharged and later turbocharged. More than 1,800 Atoms had been built by the late 2010s, and the car remains in production today.
