Automotive Systems and Performance Concepts

Which car body type is described as a classic four-door car with a trunk?

• Coupe

• SUV

• Sedan

• Hatchback

What engine characteristic is primarily responsible for a car's ability to accelerate quickly and tow heavy loads?

• Horsepower

• Cubic Centimeters (CC)

• Revolutions Per Minute (RPM)

• Torque

How does a turbocharged engine increase power without necessarily increasing the engine's physical size?

• By reducing the number of cylinders.

• By forcing extra air into the engine.

• By decreasing the engine's RPM.

• By using a smaller fuel tank.

Which drivetrain system automatically sends power to all four wheels when needed, providing better grip in slippery conditions, but is generally heavier and less fuel-efficient?

• Front-Wheel Drive (FWD)

• Rear-Wheel Drive (RWD)

• All-Wheel Drive (AWD)

• Four-Wheel Drive (4WD)

What is the primary function of an Anti-lock Braking System (ABS) in a vehicle?

• To increase the car's acceleration on slippery surfaces.

• To prevent the wheels from locking up during hard braking.

• To automatically apply the parking brake when the car is stopped.

• To enhance the car's turning radius at high speeds.

What phenomenon occurs when a vehicle's brakes become less effective due to excessive heat buildup from repeated or prolonged use?

• Brake fluid cavitation

• Brake pad glazing

• Brake fade

• Rotor warping

Which of the following best describes the difference between traction control and stability control systems in a vehicle?

• Traction control prevents wheel spin during acceleration, while stability control helps maintain vehicle direction during turns or slides.

• Traction control is only active during braking, while stability control is active during acceleration.

• Stability control prevents wheel spin during acceleration, while traction control helps maintain vehicle direction during turns or slides.

• Both systems primarily enhance braking performance in emergency situations.

Which of the following driving practices and vehicle conditions can negatively impact a car's fuel efficiency (MPG)?

• Accelerating smoothly and maintaining optimal tire pressure.

• Driving at a consistent speed of 55 mph and removing excess weight from the trunk.

• Rapid acceleration, driving above optimal speeds, and under-inflated tires.

• Regular oil changes and replacing clogged air filters.
