Volkswagen Passat BlueMotion Concept revealed ahead of Detroit debut

Cylinder deactivation is not a new thing – we have seen it on big V8 and V12 engines for some time now.

Volkswagen Passat BlueMotion Concept takes cylinder deactivation to a new level now, introducing the world’s first inline four cylinder with cylinder deactivation.

The 148bhp 1.4-litre EA211 TSI engine is linked to DSG dual-clutch automatic transmission delivering 42mpg on the US cycle, that is equivalent to 50.4mpg in the UK.

The concept is based on the US spec Passat and shows just how fuel-efficient a non-hybrid, petrol-engined mid-size saloon can be.

The 1.4-litre EA211 TSI engine with direct injection and turbocharging also offers Active Cylinder Management (ACT) technology, deactivating the valvetrain on cylinders two and three for situations when the driver only applies light throttle pressure to maintain specific city speeds.

There is no word on production plans, but we wouldn’t be surprised to see it soon in production.
