After a drawn-out development, the new TVR sports car is edging closer to its debut at the Goodwood Revival and is set to arrive with a class-leading power-to-weight ratio.

Autocar has received word that the TVR will tip the scales at just 1,200 kg (2,645 lbs) and be powered by a 5.0-liter V8 engine from Cosworth. This will result in a power-to-weight ratio of 400 hp per tonne, meaning the V8 will deliver approximately 480 hp.

In the current world of high-performance sports cars, a figure below 500 hp may not sound like enough. However, the low weight of the TVR will mean its power-to-weight ratio easily eclipses rivals like the Porsche 911 Turbo S, Aston Martin Vantage GT8, Maserati GranTurismo MC Stradale and Jaguar F-Type SVR.

All of this grunt will allow the car to hit 60 mph in less than four seconds and reach a 200 mph (321 km/h) top speed.

Discussing the car, John Chasey from TVR Manufacturing said “We have been ambitious and rigorous in establishing performance benchmarks for our new car.

“Our intentions for power-to-weight, size, practicality and quality standards were set high from the very start. We know that the new TVR must be able to compete at the very highest levels, and I’m delighted to say that the car has met or exceeded all of our own, very exacting requirements, hands down,” he said.
