Volkswagen's innovative marriage of a supercharger and a turbocharger on the same 1.4-liter engine gained the automaker two prizes (one for each induction system?) at the "International Engine of the Year Awards 2006" - "Best Engine, 1-liter to 1.4-liter category", and "Best New Engine of 2006."

VW's "maximum power - minimum consumption" strategy for the TSI powerplant led to designers using a supercharger for low-range power, and a turbocharger for efficiency at higher rpm. The twincharger system is shown in the drawing at right.

The TSI is currently available in the Golf GT and the Touran.
