Kia UK has revealed a one-off Kia Stinger GT240 which boasts a race-car interior and a tweaked engine for more power, up to 300kW+ and 560Nm of torque.

With a Kia Stinger GT S as the starting point Kia UK decided to turn up a Stinger to 11. The project was a joint project between the Kia UK press garage and technical team and boffins from the Hyundai Motor Europe Technical Centre in Rüsselsheim, Germany.

The 3.3L V6 twin-turbo petrol engine was the first thing to cop a tune with power and torque up to 300kW-plus and 560Nm of torque which is up from 270kW-plus and 510Nm. New sparkplugs were fitted (HKS M45il) a K&N sports air filter and a lightweight Milltek Sport quad-exit exhaust system with catalysts deleted were fitted. A six-row automatic transmission cooler replaced the four-row item. The transmission software was recalibrated to have quicker shifting characteristic in Sport and Sport+ modes.

The interior was stripped, removing the seats and belts, airbags, sound system, interior trim and rear window regulators. The engine cover, undercovers, parking sensors, boot and bonnet dampers and rear bumper beam and foam were also taken out, while the rear windows were glued into place and lightweight door cards installed. The Stinger’s sunroof was removed and replaced by a steel panel, shaving off a few more kilograms, even after a honeycomb panel was grafted in by Hyundai Motor Europe to add essential reinforcement to the panel. There is a total weight reduction of approximately 150kg after the installation of the roll cage, seats, belts and fire extinguisher.

A custom roll cage was installed and painted and the crash pad and necessary electronics re-assembled. Underbody stiffening comprises of a cross bar at the front and a pair of bars at the rear. A pair of Sparco race seats were bolted into place, along with race belts. Completing the weight saving measures, a Lite Blox LiPo battery is installed to replace the original item, saving 22kgs.

Wider OZ Racing Leggera rims saving approximately 5kg per wheel, and Pirelli Trofeo R tyres were selected – 235/35/R19 at the front and 265/30/R19 at the rear. Uprated front brakes saw Brembo six-pot calipers and racing steel flex pipes fitted, along with high performance 380 x 34mm discs and Endless pads. At the rear, the standard Stinger V6 brakes were utilised.

The standard dampers were kept, with Eibach Pro lowering springs and anti-roll bars of 25mm at the front. At the rear, an 17mm in-house anti-roll bar was fitted. The continuous damping control was axed in favour of a conventional damper set up.

To give it the look of a race car, a Stillen front splitter and rear diffuser were added, along with a rear spoiler by Air Design.

The car chose for the project had been destined for the crusher as it had been the original UK homologation car, the car with which engineering had signed off the ride and handling tune. It was also the star of TV shows like Top Gear and the Grand Tour. But this car won’t be raced, rather it’ll be used at special events and displayed at Kia HQ in the UK.

  1. Thanks Isaac, This engine spec should be put into production pronto as has been mooted for ages. It is all the car needs to make it truly exciting and complete package. It is currently only the equal of an XR6 Turbo but with this motor it might even rival a Sprint XR6. Performance figures? Would have though a pretty important part of a story about a car like this – totally ommitted. Why?
