Volkswagen is constantly searching for ways to bring fuel-efficient options to the midsize Passat - a smart strategy considering it competes in one of the most popular vehicle segments. You can already opt for a diesel-powered TDI model, but the new VW Passat BlueMotion Concept hints at a future technology to improve fuel economy without resorting to hybridization.

Unveiled at the Detroit Auto Show today, the BlueMotion Concept uses cylinder deactivation to turn the Passat's 1.4-liter turbocharged and direct-injected engine from an inline four-cylinder to a straight-twin. VW claims that this is the first application of cylinder deactivation on a four-cylinder engine, and it shuts down cylinders two and three when possible for optimal efficiency.

Adding in stop-start technology and the dual-clutch transmission, VW says that this car will get an estimated 42 miles per gallon on the highway. That's almost as efficient as the Passat TDI, but overall power figures are down considerably compared to that car with 150 horsepower and 184 pound-feet of torque.

The full press release from VW is posted below, but it isn't clear if - or when - such use of this tech could make it into production.Continue reading Volkswagen Passat goes green with the BlueMotion Concept
