What happens if you gradually accelerate?

Gradually accelerating allows the engine to transition gears smoothly, which is essential for maintaining optimal performance and efficiency in a vehicle. When a driver applies gradual acceleration, the vehicle's engine can adjust its power output in a controlled manner. This coordinated adjustment helps prevent unnecessary strain on the transmission and ensures that the vehicle shifts gears seamlessly. Smooth transitions not only enhance the driver's comfort but also contribute to better fuel efficiency, as the engine operates within its optimal RPM range.

The other options do not accurately represent the benefits of gradual acceleration. For instance, increasing fuel consumption is typically associated with rapid or aggressive acceleration, while stalling the vehicle is more likely to occur when acceleration is too abrupt or when shifting gears. Sudden stops are generally related to sharp braking rather than acceleration. Thus, the idea of gradually accelerating as a means for smooth engine transitions is a fundamental driving principle that promotes better vehicle handling and efficiency.
