Obviously this question is similar to How to improve fuel economy in high-mileage car? except I am asking specifically about automatic transmission car.
The car still delivers lots of power/acceleration but the fuel consumption is very high. Maybe this is a naive question but could I somehow set up the automatic transmission software to trade power for fuel efficiency?
My car is 2004 Ford Mondeo XL 2.0 Petrol and fuel consumption is cca 15 liter per 100 km (15.7 MPG) in a city.
