Question 8021
The engine of a vehicle equipped with a Start-Stop system is designed to perform better, although the number of engine starts is also higher. What advantages does this system offer?
- It increases engine power, especially when it is stopped.
- It reduces CO2 emissions and saves fuel.
- None, since enduring constant starts shortens its service life.
Show answer and explanation
Correct answer: It reduces CO2 emissions and saves fuel.
With the engine off while stopped, as at the red traffic light in the image, where the green Start-Stop indicator light is on, no fuel is used and no gases are emitted. This saves you fuel and reduces CO2 emissions. These engines start many more times than a regular engine, but they're designed for it.
