In road-going form the Jetta’s 1.4-litre, 16-valve engine produces 170 PS but the engineers at Volkswagen Racing UK have boosted this to 230 PS.

Super and turbocharged Jetta

Today at the Autosport International racing show at the NEC in Birmingham, UK Volkswagen revealed their new VW Jetta TSI Sport. The Jetta TSI Racer will make it first racing appearance on Easter Monday at the Oulton Park Volkswagen Racing Cup race.

The Volkswagen Racing UK team have upped the horsepower from 170 hp to 230 hp in the supercharged and turbocharged 1.4 liter 16-valve engine. Last year the engine was under the bonnet of the Golf, Volkswagen Racing UK’s Melissa Wright said: “We learned a lot about the engine during the course of 2007 and we have incorporated that knowledge into the new installation.”

The engine-driven supercharger and exhaust gas powered turbocharger supply the racer with low rev supercharging while the turbo kicks in at higher engine speeds. This results in no turbo lag and high torque through a wide range of engine RPM. The engine was named Best New Engine of 2006 in the International Engine of the Year Awards.
