The TVR 450 SEAC is a sports car designed and built by TVR in a one year only run between 1988 and 1989.
It used the same fibreglass and kevlar body as the 420 SEAC and the same chassis. The only difference was the engine which was increased to 4.5 litres and had a power output of about 325 bhp (242 kW) and 435 Nm torque.
As a consequence though the 450 SEAC was even more expensive to build and buy than the already expensive 420 SEAC, about 17 were made. Curiously, rumour has it that more SEAC's are on the road now than were manufactured in the first place, that is because many wedges were converted to 450 SEAC spec afterwards.
