Volkswagen's recent "innovation workshop" featured fuel-saving auto technology galore, including a 272-horsepower turbocharged engine.

The workshop revealed that VW has an even bigger trick up its sleeve than the 240-horsepower twin-turbo four-cylinder TDI already available in Europe.

"An intelligent advanced development of this TDI might take the following form: the power of the two-liter engine could be increased to 200 kW / 272 PS [272 horsepower] by the use of a variable valve train, further optimized gas exchange cycles, and what is known as an electric booster," said the automaker, according to Car and Driver.

While VW doesn't specify what an "electric booster" involves, Car and Driver speculates that it's probably an electric turbocharger, noting that Audi recently unveiled a similar powertrain innovation in the form of a diesel V-6 with an electric supercharger.

The other biggie that Volkswagen showed off at the event was a 10-speed dual-clutch automatic transmission that can handle as much as 406 pound-feet of torque. VW's current highest gear count for a U.S. model is the seven-speed dual clutch available in the Jetta Hybrid.

New technology for the cabin was showcased as well with VW revealing improved efficiency for infotainment systems, which hold navigation, audio, vehicle statuses and more.

Another latent technology for future VW cars is the new engine stop-start system that can shut down the engine at 4 mph.

In other news for the German automaker, VW passenger cars set a new delivery record for the first three quarters of this year, shipping 1.4 million vehicles in the European market. The automaker also shipped 482,300 vehicles in North America, according to Volkswagen.
