Volkswagen reveals its future technology in its latest line-up of VW Passats with the Passat BlueMotion Concept. Unveiled at the Detroit Auto Show, it boasts improved fuel economy through their cylinder deactivation.
According to VW manufactures, this is the first cylinder deactivation on a four-cylinder engine. To put this into perspective, a cylinder deactivation on a four-cylinder engine isn’t as common as one on a V8 or V12. For fuel efficiency, direct-injection inline-four turns off cylinders two and three when their power isn’t needed. This automatically saves fuel and reduces unwanted emission for city driving. This Passat, however, can still run on 42 miles per gallon driving on the highway with a 150 horsepower engine.
