What is the most fuel efficient speed to drive at KM?
Most cars, vans, pickup trucks and SUVs are most fuel-efficient when they’re travelling between 50 and 80 km per hour. Above this speed zone, vehicles use increasingly more fuel the faster they go. For example, at 120 km per hour, a vehicle uses about 20% more fuel than at 100 km per hour.
Which is the best speed for fuel economy?
So, if you’re driving a box then your best fuel economy is likely closer to 40 mph than 50. If you’re driving a teardrop shaped eco-car, then you’re likely closer to 60 mph. Of course, engine size and other factors are involved too. If you’re in a hurry, then going faster than 60 mph (95 km/h), presents new problems.
What are the rear end gears fuel economy?
Rear End Gears Fuel Economy. This is the ratio of gears in the rearend (differential) that you may have heard of in the numerical terms 2.73 to one, 3.23 to one, 3.55 to one, 3.73 to one, and 4.10 to one (commonly written in the following manner 3.23:1 with a colon). These numbers specifically relate the ratio of the speed at which…
When do you get the worst fuel mileage?
Cars get the very worst mileage at 0 mph; they use gasoline but don’t cover any miles. When you put the car in drive and start moving at say 1 mph, the car uses only a tiny bit more fuel, because the road load is very small at 1 mph. At this speed the car uses about the same amount of fuel,…
What’s the average speed at 2400 rpm in 5th gear?
If you’re turning 2300-2400 RPM in 5th gear then you don’t have the stock 3.08 gears. 3.08 gears with a T-5 and the stock 225/60/R15 tires, will yield a speed of about 85ish MPH at 2400 RPM in 5th gear. 3.73’s would put you at about 70 MPH at 2400 RPM though.

How to get the best gas mileage at the speed limit?
Observe the Speed Limit While each vehicle reaches its optimal fuel economy at a different speed (or range of speeds), gas mileage usually decreases rapidly at speeds above 50 mph. You can assume that each 5 mph you drive over 50 mph is like paying an additional $0.20 per gallon for gas. 4 Observing the speed limit is also safer.
Which is better for fuel economy 3.23s or 2.73s?
Switching from a set of 3.23s to 2.73s will lower your auto’s normal operating rpm range during driving which will translate to higher fuel economy for you the driver. The difference can be anywhere from a few mpg to several mpgs depending on how much of a smaller ratio you select.
How is hypermiling used to reduce fuel consumption?
The use of these techniques is called ” hypermiling “. Simple fuel-efficiency techniques can result in reduction in fuel consumption without resorting to radical fuel-saving techniques that can be unlawful and dangerous, such as tailgating larger vehicles.
