Allie and Mackenzie are discussing the features of regenerative braking in their engineering class. Which of the following is not a trait of regenerative braking?

• The motor-generator generates electricity during braking.

• The hydraulic brakes are only used during hard braking.

• Engine compression may be increased to aid in braking.

• The vehicle is slowed by the drag on the motor-generator.

Talal is learning about electric vehicles. Which of the following may not be a function of the motor-generator?

• It helps propel the vehicle.

• It slows the vehicle during braking.

• It cranks the internal combustion engine.

Mackenzie says a mild hybrid shuts down its internal combustion engine when the vehicle comes to a stop. Talal says all mild hybrids use a small motor-generator to assist the gas engine during acceleration. Who is right?

• A only.

• B only.

• Both A and B.

• Neither A nor B.
