These are the 10 cheapest ECO cars on the Spanish market:
1. Seat Mii&You: from €9,990

- Price: from €9,990 (applying all the brand’s discounts)
- Consumption: 2.9 kg/100 km CNG
The new Seat Mii&You features a 1.0 TGI 68 CV engine that runs on either petrol or CNG (Compressed Natural Gas). This is an urban car that costs €14,980 if paid in cash. However, if we opt for financing from the brand and trade in a vehicle, the price of the Seat Mii&You drops to €9,900.
The car has a CNG tank (11 litres capacity) and a petrol tank (10 litres). Combining both tanks, the total range of the car reaches 600 km (a considerable figure given that it’s a city vehicle).

The Seat Mii&You offers an official consumption of 2.9 kg/100 km. Given that CNG currently costs €0.885/kg, the money we would spend over 100 km would be remarkably low: €2.56/100 km. However, real-world consumption will always be somewhat higher than the brand’s figure. To give you an approximate idea, with the Seat Mii TGI you’ll save between 30% and 40% of fuel compared to its petrol equivalent (1.0 TSI 75 CV); the brand claims a 50% saving when choosing the CNG variant.
