... I read the word "Evolution" .... ok let me have a trial on that...
- 289 / Mk III Cobra (coil sprung)
- Mk IV Cobra: built essentially on the same basis as the coil sprung 289 (chassis dimensions, structure, suspension layout, body, base engine & gearbox, differential, somewhat modernized, aluminium body, dash upgrade ...)
- Superblower: as per Mk IV / engine upgrade, different dash
- CRS: as per Mk IV chassis layout, slightly modified, dash upgrade, carbon fibre bodied
- 212: as per CRS, Lotus engined, slighly modified body (indicator and rear lights basis)
- Mk V: as per CRS, latest body design as per 212, different body materials
Up to here, I reckon the evolution along the initial 289 coil sprung chassis design.
- Mk VI: all in all totally different car (dimensions, chassis structure, layout, suspension, body shape & materials, dash, engine, gearbox, differential) having existed in the replica market before it has been badged AC.
If in parallel, an expert on the matter would now state where the cars were built, who owned the premises, the engineering, the tools, who paid the men that manufactured these cars => up to and including the Mk V, beering in mind the Angliss story starting off from the other end, one can answer those questions by "AC".
As of the Mk VI, so far only the badge is "AC".
