Question 5578
Regarding efficient driving, in which passenger cars should gear changes be made, as a general rule, when the engine is between 1,500 and 2,500 revolutions per minute?
- Automatic cars with a hybrid engine.
- Those with a diesel engine.
- Those with a gasoline engine.
Show answer and explanation
Correct answer: Those with a gasoline engine.
In a gasoline engine, it is recommended to shift up between 2,000 and 2,500 rpm, the upper part of that range. A diesel engine delivers its power at lower engine speeds, so you shift up sooner.
