What happens if you slow down in high gear?
The short answer is yes. You will damage the drivetrain by lugging the engine – driving at too low a speed for your chosen gear and load. You know you are lugging the engine when you try to accelerate and the engine bogs down, stalls, or jerks continuously.
How does driving high speed on low gear damage the car?
However driving in low gears continually will result in more wear and tear of engine compared to engine driven at lower rpms. Becuase for same ODO this engine has revved more causing more frictional wear and temperatures. This is only technical aspect how many people the flip car due to engine issues.
Is it bad to drive slow at low RPMs in 4th or 5th gear?
To answer your question, no it isn’t bad for your car to keep it in as high a gear as you can while still maintaining speed. As long as you are above idle in RPM and your engine isn’t lugging, you aren’t doing any damage. See this link for more information about lugging. You mentioned that you might do this to be quieter and for fuel efficiency.
Is it bad to drive a car at high RPM?
But as long as you don’t over rev the engine, n conclusion, driving at a high rpm on an engine will obviously put some wear and tear on the engine, but it won’t cause a huge dent in your wallet. Iconic vintage photos captured a different side to history.
When does the engine stop rpm dropping below idle speed?
Unless you try something unrealistic (like trying to drive up a 20% gradient in 5th gear at 30 mph) the engine management system stops RPM dropping below idle speed in any case, by increasing the fuel supply.
Can you go high speed in low gear?
‘High speed in low gear’ is admittedly a little vague. It depends on how fast you are going, and in what gear. Most any engine built in the last 30 (or so) years has electronic fuel injection. And these engines typically have a rev limiter.
To answer your question, no it isn’t bad for your car to keep it in as high a gear as you can while still maintaining speed. As long as you are above idle in RPM and your engine isn’t lugging, you aren’t doing any damage. See this link for more information about lugging. You mentioned that you might do this to be quieter and for fuel efficiency.
What happens when your car is at high revs?
If the engine is at high revs, the engine will likely bounce off the rev limiter (or over rev on older vehicles), the engine and transmission will be torque stressed, have their life reduced or even fail. If the tyres maintain grip then they will provide a heavy braking force and the car will slow significantly.
Why do you drive in a lower gear?
This is due to the lower torque available to the rear wheels. In a lower gear, relative torque is increased and you will gain your higher speed faster with the same (or less) amount of throttle input, which means you can upshift your transmission and get your RPMs down again.
