Based on the EA211 1.4L turbo motor we sampled last year in the Euro-market Audi A3 sedan, the Passat BlueMotion Concept's engine is capable of shutting down the middle two cylinders during cruise, and features the Jetta Hybrid's gearbox, a twin-clutch unit capable of decoupling from the engine during off-throttle coasting. In the Passat's application, the 1.4 puts out 150 hp and 184 lb-ft of torque; VW suggests its highway fuel economy will stand at 42 mpg.
