The SeiGHT (pronounced variously as S-8 or 'Sayt') is a sports car manufactured as a kit or factory built vehicle by Westfield Sportscars.

It is based on the familiar Lotus Seven concept, created by Colin Chapman, whose design philosophy was to strip a car design down to bare essentials for the ultimate in driving experiences.

The Rover V8 engine powerplant of the SEiGHT ranges from 3.5 litre units originally sourced from the Rover SD1 to bored and stroked 5.2 litre units.

There are also 3.9 fuel injected versions, which are currently provided in the factory built vehicles and TVR Power engines of 4.2 litres.

One example has been built around an alloy version of the Chevrolet small block with a displacement of 6.6 litres.
