In an all gears run, the driver ________.

• A. Stays In The Lowest Gear The Entire Run
• B. Accelerates Through All Of The Gears
• C. Reaches Top Speed In Neutral
• D. Shuts Off The Engine

Answer: (B)

The main idea is that using all gears means shifting through each gear as you accelerate to keep the engine operating in its optimal power range. As you start from a stop, you move up through the gears to use the torque in each ratio, which gives you stronger and smoother acceleration. If you stayed in the lowest gear the whole run, the engine would stay at very high RPMs, wasting fuel and stressing the engine without delivering efficient speed. Reaching top speed in neutral isn’t possible because there’s no power being delivered to the wheels, and shutting off the engine stops all propulsion. So, accelerating through all gears best describes how to use the transmission during an all-gears run.
