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 moved to six-cylinder base engines to power its roadsters; now with better technology, it can accomplish the same–or more–power with turbocharged four-cylinders.

The Porsche Boxster is the sportiest competitor in the segment, and while you may deal with a little more interior noise, it's the best option for someone looking for occasional track use.

The Infiniti Q60 is comparatively bulky, but comes with a rear seat and a willing V-6 engine.

The Audi TT feels lean and sporty–and it costs less, too–but it comes standard with front-wheel drive and less power than the BMW.

There's also the Mercedes-Benz SLK 250, which feels bulkier than the Z4, but offers similarly frugal fuel economy numbers.

The 2014 Mercedes-Benz SLK is the most conservative choice amongst its competitors, but the mini-SL makes for a charming, compelling choice.
