How does the
TCC Rating work?
The TCC Rating is a clear numeric rating value based on a 10-point scale that reflects the overall opinion of our automotive experts on any vehicle and rolls up ratings we give each vehicle across sub-categories you care about like performance, safety, styling and more.

Our rating also has simple color-coded “Stop” (red), “Caution” (orange),
or “Go” (green) messages along with the numerical score so you can easily understand where we stand at a glance.

Our automotive experts then also collect and show you what other websites say about these different aspects of any vehicle. We do this leg work for you to simplify your research process.

The current BMW Z4 isn't quite as lithe as previous versions, but it's still a lot of fun to drive.

The Audi TT, though, has gone in the opposite direction; it's still more like a real sports car, with a leaner body and rear-biased all-wheel drive handling its ample turbo power.

The masculine and composed Mercedes-Benz SLK is another alternative, now in the same weight class as the Z4, and the BMW's handling edge has largely disappeared.

The Porsche Boxster is still the choice for those who must have a pure sports car; new direct-injection engines and a dual-clutch transmission option now make the Boxster even more enjoyable than before.

Another interesting alternative—and one more for luxury loafing but still enjoyable to drive, is the Infiniti G37 Convertible.

It's hefty, but a a handsome body and quick-folding top increase appeal to its rosewood-trimmed interior-and a throaty 325-hp V-6 and seven-speed automatic or six-speed manual bringing enough performance to fit in with this class.

The 2011 Audi TT straddles the line between sporty cars and true sports cars--or is it the DMZ?

The Infiniti G37 Coupe and G37 Convertible wow with sexy exteriors and lavish interiors, along with excellent performance, but they don't always meet expectations for refinement.
