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.

A new 4.0 litre twin-turbo V8 – the M178 engine – has been developed to replace the 6.2 litre V8 and, in initial tune, develops 503 bhp at 6250 rpm and 479lb/ft of torque from just 1750 rpm.
