In 1982 TVR's then new owner Peter Wheeler found himself wanting more power than the Cologne V6-equipped Tasmin 280i could offer.

Thus, based on the existing car the TVR Tasmin 350i appeared in August 1983.

[2] The 350i also provided the basis for the 390SE first seen at the Birmingham Motor Show in October 1984,[1] as well as the extreme 420/450 SEAC and other future developments.

There was a short run of non-factory Sprintex supercharged 350SX (and the bigger hearted 400SX) made by the Northern TVR Centre in the mid-1980s.

The end of the run was marked by the limited edition (25 examples only) 3.9-litre TVR 350SE of 1990-91.
