Ginetta supercar stuns ahead of Geneva debut

Ginetta has unwrapped an all-new supercar ahead of its official debut at the Geneva motor show next week.

Announcing it would go on sale in 2020, Ginetta confirmed it would make just 20 of the unnamed supercar in 2020 that will be priced from a sobering £400,000 ($A750,000).

For that you get a car that has been developed using the 61-year old brand's extensive motorsport expertise that includes the Ginetta's owner Lawrence Tomlinson who is himself a Le Mans winner.

Claimed to feature a bespoke all-new carbon-fibre tub chassis, the front mid-engine coupe's striking shape is said to be the work of extensive wind tunnel action (the British firm has access to the Williams F1 tunnel) designed to maximise the Ginetta's on-track performance.

Under the bonnet, the 6.0-litre naturally-aspirated V8 is said to produce 450kW and 705Nm of torque.

Combined with a six-speed sequential transmission that channels its power to the rear wheel through a carbon-fibre propshaft the Ginetta supercar is expected to offer ballistic levels of performance -- especially when you consider the Ginetta weighs-in at just 1150kg.

On track, using knowhow accrued from competing in LMP1 and LMP3 sportscar racing, the new McLaren Senna-rival is said to be capable of generating a mighty 376kg of downforce at 160km/h.

Riding on ultra-lightweight wheels, the Ginetta features carbon ceramic brakes and racer-style pushrod in-board suspension.

Inside, the new supercar gets a pair of ultra-lightweight Alcantara-trimmed bucket seats and a carbon-fibre steering wheel that are both inspired by real race cars.

As far as luxuries go, the Ginetta gets power steering, ABS brakes and a traction control system, a heated front and rear windscreen and a wireless phone charger.

Making up for poor visibility, there's even a reversing camera.

Perhaps the biggest surprise is, against all odds, the Ginetta gets a huge 675-litre boot making it surprisingly practical for hardcore track day fans faced with the weekly shop.

Set to go on sale in 2020, Ginetta says that the first 12 cars of the 20 allocation for 2020 have already been sold, despite the towering $750,000 price tag.

From 2021, Ginetta says it aims to preserve exclusivity by making around 30-50 cars annually.

Currently Ginetta manufacturers around 300 cars a year, although most are race- rather than road cars.
