Volkswagen’s latest track challenger, a supercharged and turbocharged Jetta saloon, has been unveiled.

The Jetta TSI Sport made its debut at the Autosport International racing car show at Birmingham’s NEC, taking centre stage on the British Racing and Sports Car Club stand.

The new machine will take to the track for the first time on Easter Monday (24 March) in the opening round of the Hankook-backed Volkswagen Racing Cup, at Oulton Park.

In road-going form the Jetta’s 1.4-litre, 16-valve engine produces 169bhp but the engineers at Volkswagen Racing UK, with the help of their technology partners at Superchips, Milltek Sport and Turbo Dynamics, have boosted this to 228bhp!

The TSI features an engine-driven supercharger and an exhaust gas powered turbocharger, arranged in series; the supercharger operates at lower engine speeds and the turbo cuts in as revs rise.

The result is excellent driveability and performance throughout the rev range, with no turbo lag and high maximum torque.

The power unit was named Best New Engine of 2006 in the International Engine of the Year Awards.
