What does it mean when your car has high rpm while driving?
revolutions per minute

When combustion occurs in the engine, the pistons move up and down. Driving at a higher RPM will demand more fuel / emissions and cause the engine to work harder.

It seems that the gears are slipping and causing the rpm’s to climb up. Check the transmission fluid and make sure that it’s full and red in color.
