Is 29 mpg combined good?
Don’t expect to attain higher than 20 mpg overall with a non-hybrid, and most offer less than 30 mpg on the highway. The best fuel-efficient non-electric vehicles get the following EPA-estimated combined numbers: Small Pickup: Chevrolet Colorado 2WD Diesel and GMC Canyon 2WD Diesel get 23 mpg.
How much does drag coefficient affect mpg?
“For a full-size truck, a change in drag coefficient of 0.01 is approximately equal to an improvement in fuel economy of 0.1 mpg on the combined city/highway driving cycle,” says GM’s Schenkel. “The same drag coefficient reduction can improve a car’s fuel economy by approximately 0.2 mpg.”
Does aerodynamics affect fuel efficiency?
THE BASICS OF AERODYNAMICS In on-highway applications, aerodynamics contributes 50% to overall fuel economy, so it’s critical that the vehicle is designed and spec’d to minimize aerodynamic drag.
How much mileage does LPG car give?

What’s considered good fuel economy?
Anything that is listed as less than 6-litres/100km or more than 16.5km/1-litre is considered to be pretty good. The first (and most common) reference is litres per 100km (litres/100km). This is how many litres of fuel the car needs in order to travel 100km. You’ll often see it referred to as ‘fuel economy’.
Does drag affect fuel consumption?
This means that if you make a 10% reduction in aerodynamic drag your highway fuel economy will improve by approximately 5%, and your city fuel economy by approximately 2%. Two things are occurring that are making aerodynamics even more important.
Does downforce increase fuel consumption?
The increase in performance from downforce is always more than what you lose from drag. For that reason F1 cars are very draggy. Therefore, back on topic, the teams seem to accept the fact that the downforce comes with an extra fuel consumption penalty because of the extra drag.
Is it cheaper to run car on LPG?
What are the costs of running an LPG car? As we mentioned earlier, LPG is roughly half the cost of petrol, that’s due to a lower fuel exercise duty. Petrol and diesel are charged at 57.95p per litre, whereas LPG is only 31.61 per/kg.
