Why do two cars have different rpms at 70 mph?
Two cars of the same make with different engines will have different RPM at 70mph. Car with more number of gear and higher engine displacement will have lower RPM. RPM is also affected by wheel size. Smaller wheels give higher RPM.
What happens if you exceed the RPM of the engine?
Every engine has a manufacturer recommended range of RPMs to operate safely. If you exceed those RPMs, you can experience internal engine failure or damage. Tip: Check your car’s user manual or the car manufacturer’s website to find a recommended range of RPMs for your car’s specific make and model.
Which is the best rpm for fuel efficiency?
Step 4: Maintain fuel efficiency. For the best fuel efficiency, keep your RPMs between 1,500 and 2,000 RPM when driving at a constant speed. Note: Your engine burns more fuel at higher RPMs. Your RPM gauge is designed to help you operate your car more efficiently and to prevent damage to your engine when driving.
Is it good to drive at high RPM?

How to calculate engine RPM at highway speed?
This calculation is used to match oversize tires with new ring and pinion gears to obtain the desired engine RPM at highway speed. Note: 336.13 is used to convert the result to RPM = [63360 inches per mile / (60 minutes per hour x Pi.)] Jeep SR4 (4 Cyl.)
