Sportec in the UK is taking the opportunity to offer its customers an Audi TT as powerful as a mid-range Porsche Panamera.

Sportec is presenting a Stage One engine performance upgrade for the upcoming Audi TT RS. The kit is available at £1,200 through the UK's official Sportec importer APS of Brackley.

Engineers took an analytical look at the new engine's data and saw an opportunity to for further performance enhancement. The result is the remapping of the ECU to increase both power and torque.

In standard form the little chilli chucker uses its turbocharged 2.5-litre five-cylinder to good effect for an output of 250kW (340hp) at 5,400rpm and maximum torque of 450Nm at 1,600rpm. Exceptional figures by anyone's measure, but not Sportec's it would seem.

The tweaks have increased power to 298kW (405hp) at 5,800rpm and torque to 544Nm at 2,650rpm. That makes it about as powerful as the previous-generation BMW M5 (E39) and as potent as the Porsche Panamera S. Performance numbers are 4.2 seconds for the 0 - 100km/h sprint, down from the standard 4.6 seconds.

More dynamic and styling upgrades are being developed at Sportec's base in Höri, Switzerland. If this is Stage One then we wait with bated breath for the next stage. The conversions are covered by a guarantee for the balance of the manufacturer's warranty.
