TSI Engine The TSI technology.

Combining driving pleasure and economy

In developing TSI technology it was our aim to create engines that offer significant benefits by reducing fuel consumption and CO2 emissions but at the same time are also impressive for their superb power delivery.

Advantages resulting from "downsizing"

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 the engine has less weight to shift in the vehicle. Volkswagen's TSI engines take full advantage of these effects.

Petrol direct injection plus charging

Pioneering technology is used in the TSI engines, combining direct petrol injection with a turbocharger or charge compression with a turbo and a supercharger, enabling them to deliver impressive performance figures and torque and to provide the driver with the full spectrum of driving pleasure despite the smaller engine. The combustion of the petrol is particularly efficient, with the result that the power output of the TSI engines is considerably higher than is the case with conventional, naturally aspirated engines.

Torque at all engine speeds

The Volkswagen TSI engines are designed to deliver maximum torque from engine speeds as low as 1500 or 1750 rpm. That is good for both driving pleasure and fuel economy. The driver can make use of the superb power delivery across a wide range of engine speeds, and the TSI engines can be combined to excellent effect with higher, fuel-saving gear ratios.

Well proven and multiple award-winning

In everyday motoring the TSI engine concept delivers outstanding economy, low fuel consumption with correspondingly reduced CO2 emissions, as well as low car tax rates for reduced engine capacity. And the motor trade is also very enthusiastic about it: the TSI twincharger won the highly respected "Engine of the Year Award" in 2009.
