All of the ingredients for creating the eye-catching ‘Stinger GT420’ were already in the car’s DNA, created by Kia engineers at the company’s Namyang development centre in Korea. A meaty 3,342cc V6 twin-turbocharged petrol engine with direct injection develops 365bhp and 510Nm out of the box, and that’s even before it has been breathed upon.

HMETC powertrain team were involved from the start to tune the Stinger GT S track car, and they recommended HKS M45il spark plugs for enhanced combustion. A K&N sports air filter and a lightweight Milltek Sport quad-exit exhaust system with catalysts deleted were fitted in place of the factory item. A six-row automatic transmission cooler is fitted, in place of a four-row item, ensuring that the automatic transmission doesn’t overheat and is up to the job on track. The transmission software was recalibrated to have quicker shifting characteristic in Sport and Sport+ modes. These measures bring the vital statistics up to a whopping 422bhp and 560Nm of torque, but any racer knows that lightness is key to making the most of this additional performance.
