No, it has been shown that driving with the tailgate down creates a sort of wind drag that actually decreases gas mileage. The article I read did not address driving with the tailgate off, however.

Do you get better gas mileage if you drive your truck with the tailgate down?

Not only is gas mileage not improved by driving with the tailgate down or removed, it gets worse. Counter-intuitively, driving with the tailgate down increases the aerodynamic profile and wind resistance, degrading fuel economy. (Mythbusters recently debunked the myth. See link.) See the Related Link for "Mythbusters Episode #43" at the bottom left.

Does riding went the tailgate down save gas?

no riding with the tailagte down does not save gas. when driving, there is a circular swirl of air made when the tailgate is up and this makes the wind coming off the front of the truck bypass the bed and continue over the back. dropping the tailgate stops this affect and droppes the gas mileage.

Which SUV is going to get me the most mileage before breaking down?

The SUV that will give you the best mileage is the one that you intend to drive the most non-aggressively. Aggressive driving leads to accidents and poor fuel consumption through repeated hard acceleration and braking. Driving your SUV easier will avoid wasting fuel and thus lead to better mileage.


Is it legal to drive in CA with your truck's tailgate down?

Hi Folks, This question is very "Specific"... Doesn't appear to me that this question has anything to do with a person with a load in their vehicle or how to mark it, how many feet the load extends past the tailgate, etc... The "Real" and "Accurate Answer" to this question is a definite "YES".. In California you are allowed to drive your Pick-Up Truck with the Tail-Gate Down... Anything else that you do with your Vehicle, Trucks or otherwise of course "Common Sense" applies here... Thanks and Have A Good Day Folks... No. If you have supplies in the back of your truck that extend a few feet past your taillights, you will need to flag the end of the supplies. If you are just trying to save on fuel by driving with your tailgate down, you may want to look up the TV show Mythbusters. They tested 2 of the same trucks, driving down the same road at the same speed, with the same weight driver... and the truck with the tailgate up got better gas mileage. Air travels over the cab and across the bed without going into the bed. Lowering the tailgate created a vortex in the bed of the truck, which caused more turbulence.

How do you get better gas mileage in a 1999 Ram v8?

1. Make sure the engine is tuned up and running correctly.2. Slow down. Driving 80mph will consume at least 20% more fuel than driving 60.3. Avoid jackrabbit starts.4. Don't waste your money on devices or additives that advertise better mileage. None of them work, in spite of what the ads say.


Would you buy a hybrid car?

It depends on what type of driving you do. Hybrid vehicles tend to get the best mileage while driving in city traffic. The increase in mileage in the city is due to the increased used of the electric motor. Most hybrids (the notable exception is the Chevy Volt) will not use their electric motors while cruising down the highway. If you tend to do more highway driving, you will likely get better gas mileage by driving a vehicle with a diesel engine. Modern diesel engines run very smoothly, reliably, and cleanly. They also have the advantage of being less complicated than a hybrid vehicle while getting comparable highway mileage. City mileage in a diesel vehicle will be better than a regular car but not quite as good as a hybrid.

Does a tourneau cover on a pickup truck increase gas mileage?

yes, a tonneau cove helps a little, it decreases the amount of wind drag on your tailgate, but so does taking the tailgate off or just putting it down if youre going on a long trip The previous answer given is technically incorrect. Usually tailgate down you increase the drag on a truck and will get worse mileage. A cover will actually improve you mileage a little but the weight of the cover may negate a portion of this. There are several studies cited online for this. Most places that talk about lowering the gate aren't basing it on science but on what they think is logical. Aerodynamics isn't about logic, it is a very complex science. Mythbusters actually tested this out, do a search on it.
