The Davrian marque was conceived by structural engineer Adrian Evans in 1967, Adrian formed Davrian Developments Ltd. and production of the cars moved to 65 North Street, Clapham. The earliest cars were open-top models, although subsequent Davrians were produced as two-seater sportscoupes.  Davrian also produced a number of Davrian Imp Saloons; lightweight replicas of the Imp for use in special saloon and modsports racing.

Construction of the cars is based upon a fibreglass monocoque bodyshell, the sills and voids of which are filled with polyurethane foam to provide additional rigidity. Imp suspension components are utilised both front and rear, although some later cars featured Davrian fabricated swinging and trailing arms. The majority of the cars are rear-engined, powered by variants of the Imp engine mated to an Imptransaxle. Early cars retained the rear-mounted Imp radiator but this was replaced from the Mk4 onwards by a front-mounted arrangement for more efficient cooling.

It is fair to say that the majority of Davrians have probably seen some competition duty, giving the marque a great competition history.

In late 1975, Davrian moved from Clapham to Wales where development continued on the Mark 7. However, ideas for a four seater car were shelved when the original Company went into receivership in February 1983.
