VW's cylinder shut off tech is a world's first for a mass-produced TSI engine
2 September 2011

Volkswagen will introduce cylinder shut-off technology to its new 1.4-litre TSI engine from 2012.

VW is the first manufacturer to implement the fuel-saving technology in a mass-produced TSI engine, a system that shuts off two of the four cylinders under low to medium loads, between 1400 and 4000rpm.

Volkswagen claims that the EU6-compliant unit saves 0.4 litres (0.09 gallons) of fuel per 100km, rising to 0.6 litres (0.13 gallons) per 100km when combined with VW’s stop-start system.

VW also says that the benefits become more obvious when driven smoothly and slowly: “At 50 km/h, in third or fourth gear, savings amount to nearly one litre per 100km.”

If driving style is deemed by the system to be too aggressive, the shut-off functionality is automatically suppressed.

    The Citroen C3 Aircross has got funky looks and a charming interior, but it's another small SUV, and another dynamic miss. Numb steering is just one thing keeping it from class best

    Diesel version of Skoda’s junior SUV is unobtrusive and undemanding, but we’d still go for the silkier petrol version of the Karoq
