Question

The purpose of upshifting is to:

A. match road speed with engine power.
B. allow the vehicle to increase speed.
C. slow down the vehicle.
D. transfer power from the transmission to the engine.

Answer 1

Upshifting is to match road speed with engine power and help the vehicle increase speed, aiding in improved fuel economy and reduced CO₂ emissions.

Step-by-step explanation:

The purpose of upshifting in a vehicle's transmission is to match road speed with engine power and allow the vehicle to increase speed. When you upshift, you're moving to a higher gear, which provides greater speed and efficiency at higher road speeds. This is critical in achieving better fuel economy and reducing CO₂ emissions, a benefit of advanced transmission technologies like those with 7+ speeds, dual clutch transmissions (DCTs), and continuously variable transmissions (CVTs).
