With this week's debut of the Volkswagen Passat BlueMotion concept at the 2014 North American International Auto Show in Detroit, the German automaker says it's out to illustrate just how fuel efficient a gas-only midsize sedan can be. The Passat BlueMotion sedan's turbocharged 1.4-liter four-cylinder with direct injection employs a number of fuel-saving technologies to help the concept achieve an estimated fuel economy of 42 mpg highway, which in real-world mileage would be best in class among non-hybrid cars of its ilk.
The engine, which makes 150 horsepower and 184 pounds-feet of torque, uses VW's Active Cylinder Management system previously employed in European Polo and Golf models. The system deactivates the valvetrain on cylinders two and three in light throttle situations to maintain specific city speeds. In addition, the Passat BlueMotion has a coasting function — also found on the Jetta Hybrid — in which the dual-clutch automatic transmission decouples the engine as soon as the driver releases the accelerator, allowing 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.
