As it works to meet stricter global emissions standards, Volkswagen is set to launch a range of new fuel-saving technologies on future models.

Among the highlights of a recent technical presentation at the carmakers’ headquarters in Wolfsburg, Germany, was the announcement of a new and more powerful TDI turbodiesel engine.

This 2.0-liter four-cylinder engine will be powerful as well as efficient, making up to 268 horsepower, according to a report from Autocar.

It will be based on the EA2888 design already used in several Volkswagen models–now rated at 150 hp–but with a new electric turbocharger, higher-pressure fuel system, and other modifications.

Manufacturers are showing considerable interest in electric turbochargers as a way to help decrease the size of engines without sacrificing the power and responsiveness of larger, naturally-aspirated units.

Whereas standard turbochargers are driven by exhaust gases and require time to spool up, electric turbos boast the instantaneous response of an electric motor, curtailing the “turbo lag” common to many cars with this type of forced induction.

Audi, which is part of the VW Group, demonstrated an electric turbo on a diesel version of its RS 5 coupe earlier this year. It’s expected to launch that technology on the SQ7–a sporty version of the next-generation Q7 SUV–in 2016.

VW may also use its electrically turbocharged engine on a large utility vehicle initially.

The new TDI engine is expected to appear in a production version of the CrossBlue seven-seat mid-size SUV. The concept first appeared at the 2013 Detroit Auto Show, with a diesel-electric hybrid powertrain.

A more powerful diesel engine was just one of many tech announcements made by Volkswagen today.

The company is also developing a 10-speed version of its DSG dual-clutch automatic transmission, as well as a new mild-hybrid system.

The latter shuts down the engine while slowing to a stop, and during coasting at higher speeds. It also uses regenerative braking to collect energy that can be used to power electrical accessories.
