The Passat BlueMotion Concept is based on the production Passat, but features an all-new version of Volkswagen’s 1.4-liter engine with direct injection and turbocharging with 150 horsepower and 184 lb-ft. of torque. The engine also features Active Cylinder Management (ACT) technology that deactivates the valvetrain on cylinders two and three for situations when the driver only applies light throttle pressure to maintain specific city speeds. The 1.4-liter powertrain also features a coasting function that decouples the DSG transmission from the engine, allowing the Passat to roll with the lowest possible mechanical drag from the other moving components.
Lastly the engine features a stop/start system, which shuts off the engine when the car comes to a temporary stop. As soon as the driver lifts their foot off the brake, the 1.4-liter four-cylinder engine starts again.
Volkswagen hasn’t announced any immediate production plans for the Passat BlueMotion concept, but we wouldn’t be surprised to see a production Passat very soon.
