Question

Difficulty: EasyUpshifting and Double Clutching

To complete a double-clutch upshift, the driver must allow engine speed to decrease while in neutral so that the engine RPM matches the higher gear.

Answer: Answer

Answer

True
The statement is correct because higher transmission gears have lower numerical gear ratios, meaning the engine must turn at a lower RPM at any given road speed. Releasing the clutch in neutral lets the engine and transmission input shaft slow down to the exact speed required for the next gear.

Step-by-Step Solution

1
Analyze the mechanical requirements of shifting into a higher gear.
Higher gears operate at a lower engine speed (RPM) relative to vehicle road speed.
Understanding gear ratios is necessary to determine proper engine speed synchronization.
2
Evaluate the middle phase of the double-clutch upshifting procedure.
After shifting into neutral and releasing the clutch pedal, the driver waits for the engine RPM to drop to the level required by the higher gear.
Releasing the clutch in neutral connects the input shaft to the engine, allowing both to decelerate together to the correct engagement speed.
3
Determine the truth value of the statement.
The statement accurately describes the required RPM adjustment during an upshift.
Allowing RPM to fall matches the lower rotational speed needed for the higher gear.
