The hotted-up Stinger is ready for track duties, but it's a one-off designed to show what can be done, not a production model.

Kia has whipped the covers off its Stinger GT420 in Britain, showing what can be done with a pre-production car and a can-do attitude.

Based on the pre-production Stinger used for Britain's media and television demands, the GT420 has been fettled to deliver 315kW of power and 560Nm of torque, 43kW and 50Nm up on the standard car.

The gains come from a sports air filter and lightweight quad-exhaust, along with an uprated transmission cooler to make sure the extra grunt doesn't put too much strain on the gearbox. Speaking of the gearbox, the engineers have tuned it to deliver faster shifts in Sport and Sport+ modes.

Working with the extra grunt is a stripped-back interior. Gone are the stock seats and seatbelts, airbags, sound system, interior trim and rear windscreen de-mist system, replaced with racing seats, proper harnesses, and a racing harness system. A LiPo battery replaces the stock unit, too, saving 22kg in the process.

Kia has also turfed the engine cover, parking sensors, dampers for the boot and bonnet, and the rear bumper beam. The rear windows are now glued into place, and lightweight door cards have been fitted – even the sunroof is gone, replaced with a welded steel panel.

A set of OZ Racing wheels slash 5kg from each corner, wrapped in Pirelli Trofeo R tyres measuring 235/35 at up front and 265/30 at the rear. Front camber has been boosted, the brakes are Brembo units at the front, and there's more aggressive venting in the bumpers to keep them cool.

Finally, there's an all-new suspension system with Eibach Pro lowering springs and stiffer anti-roll bars. All told, the GT420 is 150kg lighter than a standard Stinger.

The exterior has ben kitted out in red, white and black decals. No doubt you'll let us know what you think in the comments below.
