SEATS may not always be firing on all cylinders – after the company launched a new engine which can reduce combustion when the driver does not need a lot of power.
Experts say the system can "drastically reduce" the amount of fuel being burnt in the process.
The new SEAT Ibiza FR Edition spearheads the introduction of the Active Cylinder Technology.
In the case of the 1.4 TSI, the 140 PS four cylinder petrol engine will still spring from 0 to 60 in less than eight seconds, but it has an average fuel consumption of 60 mpg.
It replaces the 150 PS 1.4 TSI non-ACT engine, and although it takes a whisker longer – just 0.2 seconds in the sprint timing – it delivers a significant 12mpg average efficiency improvement, and 30 g/km less CO2, down to 109 g/km.
Available with a manual transmission only, it is also £1,015 cheaper than the 150 PS car it replaces, which came with a DSG automatic gearbox as standard.
The driver will save £110 a year in road tax and company car drivers will notice a difference in their tax bills too.
Cylinder deactivation is not especially new technology and several car makers have it.
The computer monitors how much power the driver is demanding, and on a light engine load and a trailing throttle it will automatically shut down one or more cylinders, but instantly adds the fuel and the spark again when more power is needed.
The FR Edition, in addition to the usual FR specification, includes red seatbelts, red brake calipers, titanium-coloured 17in alloy wheels, matching coloured door mirrors, climate control and dark tinted rear windows.
The 1.4 TSI ACT is available in standard FR trim in all three body styles: SC three door coupe, five-door hatchback and ST estate.
