What is it?
The most efficient version of the Seat Leon ever produced. It's based on the current 1.6-litre TDI diesel model, with power increased to 108bhp over the 104bhp of the standard car, but the same 184lb ft of torque.
Changes to this super-frugal version include suspension that has been lowered by 15mm over the normal Leon, to help cut drag by ten per cent, and a unique grille. The new Leon also benefits from a kerb weight that's some 90kg lighter than the older Leon Ecomotive.
Other fuel-saving measures include special low rolling resistance tyres and an extra gear, with this model featuring a six-speed manual transmission in place of the regular 1.6-litre TDI's five-speed 'box.
All those changes help this Leon to achieve headline-grabbing economy figures of up to 85.6mpg on a combined cycle, and emissions of 87g/km of CO2. That means the Ecomotive costs nothing to tax and is an appealing proposition to company car drivers.
Among the Leon's competition is the VW Golf Bluemotion, which returns 88.3mpg and 85g/km of CO2 – but it costs more than the £19,660 Leon, at £20,055.
