Nothing has gone wrong with the car.
This car is really well designed, economical, reliable and very fast. Its motor has a twin-cam 1.0L/16V engine - very powerful and with a good relation between the mechanical transmission and the engine. It replaced the CHEVROLET SPRINT and in Colombia's topography, this is a car adapted very well for it. The most important thing of this car is the economy - in terms of petrol consumption it consumes over 80mpg in road traffic and 86 mpg on highways. It's safe in pronounced curves.
I think you made a mistake it's not 80 miles per gallon, it's 80 kilometers per gallon, that should be about 50 MPG.
I'm happy with my new chevrolet alto is cool, safe, fast and the economy is great.
I cannot believe 80km/gallon, why they did not make a taxi version?
