People always joke that Porsche just made the same car, the Porsche 911, with marginal improvements for decades, but that's just not true. It actually makes a seemingly infinite number of variants of the 911, and it has become so confusing that the company produces a video to educate us.
It is admittedly confusing to have a clear idea of what the difference between a Porsche 91
The 911 nomenclature follows a loose model pattern, that would be 911, then body type, ie Carrera, GT3, Targa, etc., then layout drive, if it is all-wheel drive, which adds the 4 in Carrera 4 and 4 Targa 4S, then usually ends with a name for the engine and equipment options, so S for Turbo S or RS for the GT3 RS.
The 911 Carrera is the base model of the car, then the convertible is the fabric convertible version. These are rear-wheel drive, where the Carrera 4 is the all-wheel drive. The Carrera T is described in the video as the "essence" of the 911, focusing on the essential aspects of driving and the slot under the Carrera S.
The Carrera S has more power and improved technology, such as optional four-wheel steering. The Carrera GTS is the sportiest all-wheel drive 911. The 911 Targa is just four-wheel-drive, and essentially the convertible 1111.
Then there's the 911 Turbo and Turbo S, which were then called so because they're exclusive came equipped with a turbocharger. Since most 911s are now charged, it just refers to a sportier style with a wider track and a stronger model.
The 911 GT are the off-road vehicles, starting with the GT3, which is still aspirated. The GT3 RS is even more refined to produce more power and move faster thanks to its lower weight. Then the 911 GT2 RS is even more intense and is not based on the naturally aspirated engine, but on the Turbo S model. It's the fastest legal 911 money you can buy, for the time being.
Porsche would not make so many variations if they were not so popular, but there is also a strange severity over what Porsche may miss with the iconic change 911. Hardcore fans of the car essentially want a modern version the original that connects Porsche with engines and styling, which is why each new generation just gets a little bit bigger and just a little bit different.
But if Porsche goes and wants the 911 Purists, and then chained that car into all those weird variations, they can satisfy everyone. The only downside is a somewhat confusing lineup.
