Volkswagen Passat BlueMotion Concept Expected to Achieve 42 mpg

Volkswagen has recently unveiled a new concept at the 2014 North American International Auto Show in Detroit: the Volkswagen Passat BlueMotion concept. Volkswagen says their goal to illustrate just how fuel efficient a gas-only midsize sedan can be. The concept car is said to return gas mileage of up to 42 mpg on the highway, though Volkswagen hasn’t specified all three components of an EPA rating.

The Volkswagen Passat BlueMotion Concept features a direct-injected and turbocharged 150-horsepower engine. The 1.4-liter four-cylinder engine, which makes 184 pounds-feet of torque, uses VW’s Active Cylinder Management system previously present in European Polo and Golf models. The system deactivates the valve train on cylinders two and three in light throttle situations to maintain specific city speeds.

In addition, the Passat BlueMotion has a coasting function, which is also found on the Jetta Hybrid. The costing function allows the dual-clutch automatic transmission to decouple the engine as soon as the driver releases the accelerator, permitting the car to roll with the lowest possible mechanical drag from the other moving components, according to VW.

The third fuel-saving function used by the Passat BlueMotion is an engine stop-start feature. The stop-start feature shuts off the engine when the car comes to a temporary stop. As soon as the driver lifts their foot off the brake, the engine starts again. All these measures result in a manufacturer estimated highway fuel economy rating of 42 mpg.
