About This Quiz

Think you know what makes good performance? Take this HowStuffWorks quiz to test your knowledge!

You push on your car's gas pedal and the engine goes vroom. For some people, that's all they need. But if you love cars and love the performance features of them, you probably know a bit about what makes for good performance... and what doesn't.

Some people don't consider performance a factor when purchasing a new car - at least not past simple specifications such as acceleration, ride and speed. After all, do you know how many seconds it takes your car to go from zero to sixty? Probably not. But, if you've actually timed that, then you likely know about performance factors such as intake, timing, compression, and exhaust. From the engine to the tailpipe, it's all about how the vehicle performs.

So, if you know that proper tire inflation increases fuel efficiency by reducing friction, that engines need air and fuel to go vroom, and that a buildup of crud (yup, that's a technical automotive term) on the engine can kill your car's performance, you just might be able to ace this quiz.

We challenge you since you think you are an engine performance whiz, to take this HowStuffWorks quiz!
