CVT Quiz
by Staff
The continuously variable transmission (CVT), which was conceptualized more than 500 years ago, is just now beginning to replace traditional automatic transmissions in some automobiles. Test your knowledge of how CVTs work in this quiz.

The ratio of engine shaft speed to driveshaft speed is referred to as a:

  • gear
  • clutch
  • toroidal ratio

What do conventional automatic transmissions have that CVTs don't?

  • a reverse gear
  • a stick shift
  • a gearbox

Which of the following is not one of the key elements that enable CVT technology to work?

  • the clutch
  • a high-power belt
  • an output "driven" pulley

The distance between the center of the pulleys to where the belt makes contact in the groove is known as:

  • high gear
  • low gear
  • pitch radius

Which pulley in a CVT transfers energy to the driveshaft?

  • driving pulley
  • driven pulley
  • variable pulley

What does a toroidal CVT system replace the belts and pulleys with?

  • wheels
  • discs and power rollers
  • variable displacement pumps

Which of the following is not one of the benefits of CVTs?

  • improved fuel efficiency
  • a smoother ride
  • greater horsepower

How much faster should a car with a CVT reach 60 mph (97 kph) than the same car with the same engine and a manual transmission?

  • 10 percent
  • 25 percent
  • 40 percent

Who sketched the first continuously variable transmission?

  • Rudolf Diesel
  • Henry Ford
  • Leonardo da Vinci

When was a CVT first produced in a car?

  • 1920
  • 1945
  • 1958
