With the arrival of the new Audi A8, Audi also announced a new naming scheme that would badge the vehicles based on their horsepower, rather than the engine size. The good news is that the somewhat controversial naming scheme is not coming to the United States.
The new naming scheme would replace badges, like 2.0T and 3.0T with two numbers that would range from 30-70 based on how much power the engine generates. The two numbers don’t directly state how much power is under the hood and instead they just represent a range. For example, the 30 marked models generate between 109 and 129 horsepower, while the models with the 45 badge generate between 227 and 248 horsepower. It’s just a little confusing. Luckily at the debut of the 2019 Audi A7, Audi representatives revealed that the naming system will not be used on Audi’s U.S. models.
The updated naming scheme is needed more in Europe than the United States, since there are more gasoline and diesel options to choose from. Here in the United States, most of Audi’s models are only offered with a few engine options that are easily distinguished by the engine size.
