More efficiency, less pollution, unlimited driving pleasure: technologies and products that achieve environmentally compatible mobility without sacrificing dynamic performance and everyday suitability are bundled by Volkswagen under the umbrella brand BlueMotionTechnologies. An important element of this are the TDI engines.

TDI – state-of-the-art diesel technology from Volkswagen

The term TDI is often seen as a synonym for a diesel engine offering bountiful torque delivery, outstanding power output and low fuel consumption figures. From a technical standpoint, however, Volkswagen uses the name TDI to designate all of its highly sophisticated diesel engines featuring direct injection and turbocharging.

The fundamental characteristics shared by all TDI engines are high-pressure fuel injection and variable turbine geometry for excellent cylinder charging and an efficient combustion process. At the same time, Volkswagen is increasingly deploying innovative common-rail technology.

Diesel direct injection currently offers a higher degree of engine efficiency – up to 45 percent – than any other technology. Consequently, a large part of the energy stored in the fuel is transformed into kinetic energy and, as a result, engine power. This is dependent on extremely efficient combustion of the fuel. The geometry of the combustion chamber and the atomisation of the fuel play a decisive role here.

Advantages at a glance

Advantages at a glance

  • All TDI engines stand out for their excellent cost efficiency. Economical fuel consumption, long service and maintenance intervals, as well as low emissions combine to keep costs low.
  • Turbodiesel engines from Volkswagen offer refined power delivery from low engine speeds all the way up the rev scale. This results in tremendous fun at the wheel, thanks to the excellent acceleration and above-average performance figures.
  • High torque levels over a wide rev range and a high maximum output combined with minimal fuel consumption generate a sense of refined driving pleasure.
