TCC Rating
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.

A decade ago, BMW and Mercedes-Benz has gone to six-cylinder base engines for their roadsters; now with better engine technology—especially turbocharging—they're returning to fours.

Like the Z4 28i, the Mercedes-Benz SLK 250 offers strong fuel economy, although the SLK tends to feel a bit bulkier.

The Infiniti G37 is also at the portly end of the scale, although its strong V-6 is an asset.

The Audi TT is more of a sports car in its current generation and is a lean-feeling alternative that costs less.

The Porsche Boxster stands as the most serious sports car in the group, and it's probably the top choice for those who also plan to take their car out on the track once in a while; the only disadvantage of the Porsche is that you get a little more interior noise.

The 2013 Infiniti G37 Coupe is a sexy, lavishly equipped luxury car that isn't quite up with its German targets for refinement, but enthusiasts may prefer its sharper performance.

The 2013 Mercedes-Benz SLK is the least polarizing of the roadsters, but there's enough urgency to go with its elegant, mini-SL charm.
