Volkswagen has introduced a high-powered four-cylinder 2.0-liter turbodiesel engine during a technical presentation held at home in Wolfsburg, Germany.

A few months ago, Volkswagen came out with the all-new Passat which among many engines is offered with a four-cylinder, 2.0-liter TDI bi-turbo rated at up to 240 HP (176 kW). The same engine has now received a two-stage electrically operated turbocharger which has managed to bump output to 272 HP (200 kW). There's no word yet about the torque figure yet but chances are it's a bit higher than the 500 Nm (369 lb-ft) available in the Passat.

The additional power was obtained not only by implementing an electric turbocharger but also by installing a new variable valve timing system and a Piezo common rail injection system working at pressures of up to 2,500 bar.

Volkswagen has also provided some preliminary details about its forthcoming 10-speed DSG transmission which will be able to cope with up to 550 Nm (405 lb-ft) of torque. Codenamed DQ551, the ‘box is actually an evolution of the six-speed unit and will feature a coasting function to save fuel along with a new brake energy recuperation system which promises to be more efficient than before.

More details about all the innovations can be accessed from the press release below.
