Edmunds tests hundreds of vehicles a year. Cars, trucks, SUVs, we run them all, and the numbers always tell a story. With that in mind we present "Track Tested," a quick rundown of all the data we collect at the track, along with comments direct from the test drivers. Enjoy.

As of this writing, our long-term 2012 Toyota Prius C is the most fuel-efficient car we've ever had in our long-term fleet. The small, 1.5-liter Atkinson-cycle engine hooked to a pair of electric motors has pushed our Prius through the 40-mpg barrier and is currently returning an average of 44.9 mpg.

But that's only part of the story. The new baby Prius was decontented to help offset the cost of the hybrid system. While that means some less-than-stellar materials and some serious wind/road noise, it also means the Prius C is the lightest car in the Prius family and when we hear lightness, we think performance.

So along with being cheaper and more fuel-efficient — the 2012 Toyota Prius C returns 53 city/46 highway and 50 mpg combined while the Prius does 51/48 and 50 combined — is the C also the best-handling Prius (a low bar) available? We took it to the track to find out.

Comments:

Acceleration: It mattered not if I selected "D" or "B." The Prius C is slow. There's just no way around this fact. I don't recall Prii being this loud; however, both engine and wind noise are pretty extreme. I was almost able to recapture the electricity spent on the quarter-mile on the coast-down following the run.

Braking: Quite a large nosedive and some rear-end wiggle. Consistently firm pedal and stopping distances despite the light rear. Shortest distance was on 4th stop.

Handling:

Skid pad: Reasonably high threshold before ESC (nondefeatable) trims brakes/throttle. Steering also is more lifelike than I remember a Prius having — adequate build-up, less artificial spring-back. Good impressions, so-so results.

Slalom: Surprisingly "pointy" and good in transitions — right up until nondefeat ESC dabs brakes. Still much sportier and capable than similar hybrids. As with skid pad, feels better than the numbers suggest.
