Porsche really feels the need to fill every niche, not only across the entire spectrum of cars, with two SUVs, two sedans, wagon versions of the sedans and coupe versions of the SUVs, and two sports cars, each of which comes in half a dozen flavors or more. But to label a 911 as “T” is nothing new. The moniker goes back to 1969, when a 911T was simply the entry model, below the 911E and top-performing 911S. For 2018, the letter T was revived and applied to the 911, and other models shortly thereafter.
