TSI Petrol Engines
Maximum Power, Minimum Fuel Consumption
Welcome to the future of petrol technology with Volkswagen’s new TSI engines.

TSI, or Turbo Stratified Injection, is Volkswagen’s term for its turbocharged FSI (direct petrol injection) engines. Within the TSI family of engines is also what is known as the ‘twincharger’. These engines incorporate a mechanical supercharger to increase performance and torque in the lower rev range. The TSI twincharger was voted Best New Engine in 2006 at the International Engine of the Year Awards.

The new TSI twincharger engines have a smaller capacity in comparison to traditional performance engines, but they boast both a turbocharger and a mechanically driven supercharger. This innovative combination ensures power delivery throughout the speed range with no turbo lag, allowing this unique Volkswagen technology and engine to not only deliver outstanding power, but also low fuel consumption. The impressively high torque across a broad range of engine speeds permits a relaxing driving style with minimal gear changes.

As an example, the Golf GT fitted with a 1.4 litre TSI twincharger engine, puts out an impressive 125kW (170bhp) and uses its twincharger technology to propel you from 0-100kph in just 7.7 secs. Yet, incredibly, it consumes just 7.2L/100km, or over 38mpg, and emits just 169g of CO2 per kilometre.

When it comes to cost the TSI offers the benefits of low maintenance and durable technology, promising more driving enjoyment from your car.

Volkswagen has further plans to make TSI technology available in other models enabling the improved driving pleasure and economy to be experienced on more models in the range.
