The new SEAT Leon Ecomotive, the most environmentally-friendly car the company has ever produced, is on sale now priced from £19,360.

Power comes from a 1.6-litre TDI diesel engine producing 110PS, mated to a six-speed manual gearbox with revised ratios.

Further changes include the use of low rolling resistance tyres, a 15mm reduction in ride height, a unique front grille and side and rear spoilers to improve aerodynamic efficiency.

Coupled with the standard Leon’s existing start/stop and brake energy recovery systems, the Leon Ecomotive can achieve 85.6 mpg on the combined cycle, with CO2 emissions of just 87 g/km, placing it firmly in VED Band A with a zero-rated road tax bill.

The eco theme hasn’t arrived at the expense of create comforts, thankfully, and the Leon Ecomotive – based on the SE spec – still features 16-inch alloy wheels, front fog lights, cruise control, electric windows, air conditioning and Bluetooth connectivity.

If ordered before the end of 2013, SEAT will also throw in the Technology Pack free of charge, incorporating full LED headlights, satellite navigation and DAB digital radio.

Available to order now, first deliveries of the Leon Ecomotive are expected to begin in January 2014.

Prices start at £19,360 for the three-door Leon SC Ecomotive, £19,660 for the five-door, and £20,485 for the ST estate model.
