There's no hybrid or diesel tech in sight, and it's coming to the US.
The release of the Passat BlueMotion Concept at the Detroit Motor Show next week could see the first of VW's fuel-efficient BlueMotion branded cars come to the US. Another first is the use of cylinder deactivation in a four-cylinder engine, which is what gives the concept such impressive fuel efficiency figures. Without the use of hybrid or diesel tech, the 1.4-liter turbocharged inline-four rated at 150 hp and 184 lb-ft of torque, returns 42 mpg on the highway.
The direct-injection four-pot turns into a twin by shutting down its second and third cylinders when their power isn't required, and returns to a four when the throttle is more firmly pressed. Other fuel-saving tech include transmission decoupling and Stop/Start. The Reef Blue Metallic concept with two-tone interior is based on a US-spec Passat, so it's only a matter of when and not if, the Passat BlueMotion heads to production.
