Seat has revealed prices and full details for the Leon Ecomotive, the cleanest and most frugal version of its lower medium model yet.

The 85.6mpg and 87g/km Leon will start at £19,360 for the three-door SC variant with first deliveries due in January 2014.

It’s also available in five-door and ST estate bodystyles and is powered by a 110hp 1.6-litre TDI diesel engine (5hp more powerful than the previous Leon Ecomotive).

It sits 15mm lower than the standard car and gets low rolling-resistance tyres and a series of aerodynamic upgrades. Standard equipment includes 16-inch alloy wheels, front fog lights, cruise control, a leather steering wheel and gear knob, air-conditioning, electric windows, Bluetooth and the firm’s Easy Connect multimedia system.
