Is it better to accelerate quickly or slowly?
Cars get poorer fuel economy in lower gears, and accelerating too slowly prevents upshifting at an efficient rate. … But in our testing we found that taking 15 seconds to accelerate to 50 mph used less fuel than taking 30 seconds to reach the same speed, because the car entered its top, fuel-saving gear sooner.
Is it bad to run your car at 3000 rpm?
Running an engine some 3000 RPM below its redline should be absolutely find for extended periods of time. It might “sound” a bit revvy if you run the engine at that RPM when stationary – and indeed it might get hot quite quickly as it will not have the cooling airflow that occurs when driving.
How much fuel is in a horsepower?

What RPM should a car drive at?
For a passenger car engine, idle speed is customarily between 600 and 1000 rpm. For medium and heavy duty trucks, it is approximately 600 rpm. For many single-cylinder motorcycle engines, idle speed is set between 1200 and 1500 rpm. Two-cylinder motorcycle engines are often set around 1000 rpm.

According to the U.S. Department of Energy (DOE), most cars’ fuel efficiency peaks at speeds from 35 to 60 miles per hour.
What engine is more fuel efficient?
Diesel enginesDiesel engines are more fuel-efficient and have more low-end torque than similar-sized gasoline engines, and diesel fuel contains roughly 10% to 15% more energy than gasoline. So, diesel vehicles can often go about 20% to 35% farther on a gallon of fuel than their gasoline counterparts.
At what RPM is an engine most efficient?
