VW to intro Passat BlueMotion Concept at Detroit auto show

While performance heads are anxiously awaiting the North American debut of the hot-heat Mk VII Golf R at the Detroit auto show, Volkswagen's Passat BlueMotion Concept offers never-before technology in the Yank/Canuck family sedan segment: a four-pot motor with cylinder deactivation. 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.

For starters, the Laguna is the latest car to be lighter than the model it replaces; despite being longer, wider and taller, it's an average 15kg skinnier across the range, which should boost performance, economy and emissions.
