Change your driving habits and save on fuel

Motorweek did an interesting test. They took 2 identical Chrysler 300C with the big 5.7l Hemi engine and cylinder cut-off technology. They are rated at 18 mpg city and 24 mpg highway. They had those cars driven by two drivers with very different driving style. One was driving very aggressively, over the speed limit, stopping and accelerating, braking hard, accelerating hard, etc.. The other one drove like his mother was in the car.

As you expect their fuel mileage differed:

1) Driving 30 miles on rural country roads

Aggressive driving: 17.6 mpg
Conservative driving: 18.4 mpg
Difference : 4% savings

2) Highway driving

Aggressive driving: 17.0 mpg
Conservative driving: 24.4 mpg
Difference : 43% savings!!!

This is very impressive. It just demonstrates that driving faster a highway speed consumes a lot more fuel than driving slower.


3) Stop and go city driving

Aggressive driving: 17.1 mpg
Conservative driving: 19.5 mpg
Difference : 14% savings

Conclusion: If you want to save on fuel, hold your horses!
