Does high RPM consume more fuel?
If you drive your car at a higher rpm range, you will definitely consume more fuel. Also, if you shift gears often, your engine goes through fluctuation of torque output which causes it to consume more fuel.
What is the ideal RPM?
In most of today’s cars, an idle speed of 600 to 1000 RPMs is average. If your car is idling rough, though, it won’t feel smooth. The RPMs will jump up and down, for example, or they’ll fall below 600 RPM (or whatever is typical for your vehicle).
What should I drive to get maximum fuel efficiency?
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, but it went 1 mile in an hour. This represents a dramatic increase in mileage.
What makes a manual transmission more fuel efficient?
A manual transmission gives the driver full control over rpm because the driver can make the engine speed up or slow down via gear selection. The lower the gear, the higher the rpm. The higher the rpm, the more torque the engine is producing, and the more fuel it is using.
How does the fuel efficiency of a car work?
In effect the efficiency of the engine is improving. It uses a fixed amount of fuel to power itself and the accessories, and a variable amount of fuel depending on the power required to keep the car going at a given speed. So in terms of fuel used per mile, the faster the car goes, the better use we make of that fixed amount of fuel required.
When to shift to Top Gear for fuel economy?
Optimal shift points vary, depending on the engine/gearing combination, but for best economy you might need to shift to second by about 15 mph, and reach top gear by the time you’re traveling 30 to 35 mph. Rule of thumb: If the engine is revving faster than necessary to sustain an even road speed, move to the next higher gear.
What’s the best rpm for a car engine?
Short version: Almost nowhere in life is a Magic Number that meets all your needs. The ultimate economy is obtained at the lowest rpm that is in the power band. This varies from one to another with wild differences. Small engines are best at 2000 to 2400 while large engines are most efficient at 1100–1400 rpms.

Why is peak power rated at the RPM?
The RPM at which peak power is rated is the RPM for maximum EFFICIENCY OF THE ENGINE and not the overall efficiency which includes efficiencies of other transmission and attached components on the engine like gearbox, axles, bearings, alternator, AC etc. And also external resitances like wind, inclines, road friction also will hamper your mileage.
