On Monday, Porsche introduced five new versions of its iconic 911 sports car.

All five models bear the GTS nomenclature. They include the Carrera GTS Coupe, the Carrera 4 GTS Coupe, the Carrera GTS Cabriolet, the Carrera 4 GTS Cabriolet, and the Targa 4 GTS.

The GTS cars are all powered by a 450 horsepower variant of Porsche's new 3.0, twin-turbocharged, flat-six. According to Porsche, the Carrera 4 GTS Coupe can hit 60 mph in just 3.4 seconds while the rear-drive Carrera GTS Coupe can reach a top speed of 193 mph.

All GTS cars come standard with a seven-speed manual transmission while a seven-speed PDK dual-clutch unit is available as an option.

The 2017 Porsche 911 GTS cars are expected to hit US showrooms in April with a price range starting at $119,000 for the Carrera GTS Coupe up to $138,200 for the Targa 4 GTS.

With the introduction of the GTS models, all 2017 model year 911s have been upgraded to next generation 991.2 specifications. The 991.2 features an updated chassis, upgraded aerodynamics, and a new twin-turbocharged, flat-six-cylinder engine.

There are few cars in the world more iconic than the Porsche 911. Over the years, the rear-engined 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.

However, you often hear the complaint that all current 911s pretty much look same. And if you ask critics such as ex-"Top Gear" host and longtime newspaper columnist Jeremy Clarkson, 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, but 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 most current lineup of Porsche's 911 Taco Bell menu.
