Well we can buy it now, but surely this car borders on dangerously slow. You may get away with it in town but on the open road you will struggle.
But heres an interesting thought, this car has emissions of 88g/km CO2, but is only a two seater. There are a number of four/five seater cars which have emissions of 98-99 g/km CO2. So to transport more than 2 people you will need 2 cars, very economic!
Ok so most journeys have only one person in the car, but I can promise you there will be times when you need more seats and will be longing after that Fiesta Econetic. Plus, given how underpowered it is, even for a small car, how close will you actually get to that economy figure?
