SEAT is expanding the Mii family with the introduction of the new SEAT Mii Ecofuel – the company’s lowest-emitting production car ever. The Mii Ecofuel runs on compressed natural gas (CNG), bringing outstanding efficiency and significantly reduced running costs without sacrificing the fun driving dynamics that the Mii is synonymous with.
The first model with a CNG engine to wear a SEAT badge, and making its debut at the Geneva Motor Show 2013 (4-6 March), the Mii Ecofuel boasts average consumption of just 2.9 kg CNG/100 km. And because the fuel price over this distance is less than 3 Euros (approximately £2.60) in many countries*, the running costs are approximately half those of a Mii with a petrol engine.
The 1.0-litre, 68 PS engine is based on the three-cylinder petrol unit found in the Mii (with 60 PS and 75 PS outputs), but it’s been specifically developed for CNG operation. Its CO2 figure of just 79 g/km is best-in-class.
“The new SEAT Mii Ecofuel now makes environmentally friendly CNG technology affordable for all,” explains James Muir, President of SEAT S.A. “Its attractive starting price and exceptionally low consumption and emissions figures make the Mii Ecofuel one of the most interesting and sensible choices available – even for high-mileage drivers.”
At an entry price of €12,050 in Germany, the new SEAT Mii Ecofuel is the most inexpensive CNG model on the market. The outstanding value-for-money and low maintenance costs are typical for SEAT.
