SEAC is an acronym that will raise the pulse of any TVR fan. Designating "Special Edition Aramid Composite", this was the ultimate wedge. Supposedly indicating a composite body to reduce weight, only the first twenty or so were in fact Kevlar. The remainder were in fact GRP like all TVR's. By looking closely enough, you should be able to see the weave of the carbon fibre. The rationale for using a composite was that it reduced the weight of the car by around 200 lbs, with obvious performance benefits, but without losing strength. Rigidity was also achieved by making the body a one piece item. The styling was subtley different to the 390, the body being 7 inches shorter and 2 inches wider, with a more rounded nose. A huge rear spoiler is unique to the SEAC's.

The first SEAC was produced in 1986, costing twice as much as the 'basic' 350, this model used a 4.2 litre version of the Rover V8. The engines were in a higher state of tune than the standard SE cars, with high lift camshafts and some fitted with solid lifters.

The 450 SEAC was introduced in 1988. Less than forty cars were produced in total with only about a dozen being the 450's.

Curiously, rumour has it that more SEAC's are on the road now than were manufactured in the first place...

Sean Hayes' 420 SEAC "To me the SEAC represented the ultimate TVR - even though the Griffs, Chimaeras, S's, Cerberas etc all exist - I'm a wedge fan at heart. After having my 350i for 3 years I wanted to get a 390 SE and when I started looking I felt that why should I stop there and so I began searching for a SEAC. I came across about 4 SEACs 3 420s and a 450 in the time I was looking and plumped for my car now - blue, lowered VERY quick, tidy, noisy etc. I drove them all and this one felt the best and was within price range! I run Yokohama AVS rubber which, surprisingly on a car such as this, have given me over 2 1/2 years of grip (about 10k miles) and that includes track day wear."

1 - Not sure if this is the for the composite models or the GRP models
