Inside VW.

In developing TSI technology it was our aim to create engines that offer significant benefits by reducing fuel consumption and CO2 emissions while offering impressive power delivery.

The recipe for the success of Volkswagen’s TSI engines is to be found in “downsizing.” Maximum power is obtained with minimum fuel consumption from a smaller engine. The reduction in engine size has brought better efficiency, as there is less power loss resulting from friction. The smaller engines also have the advantage of being lighter from the outset, so there's less weight to shift in the vehicle. Volkswagen’s TSI engines take full advantage of these effects.

Pioneering technology used in TSI engines combines direct fuel injection with a turbocharger or charge compression with a turbo and a supercharger, enabling them to deliver impressive performance figures and torque as well as the full spectrum of driving pleasure despite their smaller size. Combustion of fuel is particularly efficient, with the result that power output of TSI engines is considerably higher than that of conventional, naturally aspirated engines.

Volkswagen TSI engines are designed to deliver maximum torque from engine speeds as low as 1500 or 1800 rpm. This translates into driving pleasure and fuel economy. The driver can make use of superb power delivery across a wide range of engine speeds, and TSI engines can be combined to excellent effect with higher, fuel-saving gear ratios.
