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.

Now that we've seen how it works, there are three big questions that remain on the 2011 Chevy Volt: What's it drive like? What's it return on a reasonable fuel economy loop? And what does the Chevy Volt do at the track?

Chevy dropped off a fully loaded Volt (parking sensors, leather, polished wheels...$43K) to our office, and the night before testing, we set it up at a special charging station at our test track where, the next morning, we'd have a full battery pack to deplete while running the 2011 Volt through our battery of performance tests.

So, what's the Volt's 0-60 and quarter-mile? And how does running in gas-engine generator mode affect the numbers?

Acceleration Comments: EV mode: Exceptionally quiet with just a little bit of motor whine, but mostly just wind noise. Very linear acceleration. Obviously, no shifting. A little bit of brake-throttle overlap is good for best launch. Best results in Sport mode. Gas-generator mode: Still linear, but you can definitely hear/feel the engine thrum.

Braking Comments: Consistent stopping distance, negligible fade, firm pedal, some rear-end wiggle and wander. Pronounced dive.

Handling Comments: Skid pad: Very little, if any, brake correction; rather it just hits a wall of understeer. Steering is light and vague. Slalom: Prefers less-is-more with as little steering input as possible. Steering is responsive, but vague feeling. if ESC does begin to intervene, then the run is no good.
