Here's your guide to all 22 versions of the Porsche 911

There are few vehicles in the automotive universe more iconic than the Porsche 911.

Over the years, the rear-engine sports car has gotten bigger, faster, and more technologically advanced. But its spirited driving dynamics and on-track capabilities have continued to make it a favorite among enthusiasts worldwide.

You often hear the complaint that all current 911s look pretty much the same. And if you ask critics such as Jeremy Clarkson, host of Amazon's "Grand Tour" show, he'll tell you that all Porsche 911s since the model's debut in 1963 look identical.

The truth is, most of the various versions of the current generation of 911s do look similar, yet they can all be identified by numerous subtle but important differences.

Like Taco Bell in the fast-food industry, what Porsche has managed to do so successfully is create multiple iterations of the 911 by mixing and matching the same ingredients, and packaging them in a lot of different ways. And if you've ever driven a 911, you'll probably agree with me in saying there's absolutely nothing wrong with that.

So here it is, the current lineup of Porsche's 911 menu.
