London show: TVR teases next sportscar

REVENANT British sportscar-maker TVR has revealed a glimpse of its first vehicle in more than a decade, with a video that shows a team of its designers marking out a monochrome impression of the mysterious model in drafting tape.

To date, the new model has only been referred to by its T37 codename, but it is flanked in the image by two previous generations of the company's Tuscan, indicating the car-maker is likely to resurrect the moniker for its new coupe.

Little detail has been revealed through the first teaser sketch but the new model appears to have adopted the large circle-perforated grille of the previous Tuscan Speed Six – the car to its left – and appears in hard-top form.

The car-maker has revealed that the model will be offered in both coupe and convertible body styles, which would also align with the previous Tuscan's variant pool.

That car's name was derived from the high-performance six-cylinder engine under its bonnet, but with a V8 powering the next version, TVR's new car might adopt a Speed Eight suffix.

What appears to be a large bonnet vent will feed air to a naturally aspirated front-mounted Cosworth V8 complete with dry-sump, and while many manufacturers seek to tame large power outputs with automatic transmissions, the TVR will send torque to the back axle via a manual gearbox.

Pricing is not expected until at least after the car has been revealed in full, but previous TVR models were known for punching above their weight in the performance versus cost equation, and the new car will be no different, it says.

“Production of the car will begin in 2017, and will be offered to the market at a competitive price point within its segment and consistent with TVR’s positioning in the past,” it said in a statement last year.

Cost will be partly minimised by legendary car designer Gordon Murray and his iStream carbon-fibre construction system, that will be used to form the vehicle's chassis and equip it with “F1-inspired ground effect technology”.

In early 2015 the company had already generated enough interest to secure about 350 orders sight unseen, but that number is expected to have swelled in the ensuing months.

Where previous TVRs were born at the company's headquarters in Blackpool, United Kingdom, the next-gen Tuscan will be built at a new manufacturing facility,which is under construction in Wales, assisted by a £30m ($A59m) government grant.
