It is believed the Audi Q1 was initially called Q2 but the Ingolstadt-based automaker had to change its name because Fiat owns the rights for “Q2”. As a consequence, the company’s upcoming entry-level model will be commercialized with the Q1 moniker and Audi has already confirmed that it will enter production in 2016.
The report specifies that Audi contacted Fiat Chrysler Automobiles (FCA) and offered a substantial amount of money to purchase the rights to use the “Q2” name but apparently the offer was denied so Audi had to think of something else. The same thing happened with the “Q4” name and now Audi has probably decided to use the TTQ moniker for yet another crossover which will be a production variant of the TT offroad concept and should be out sometime in 2017 as a sportier alternative to the Q3 compact crossover.
Getting back to the Q2 and Q4 names, Alfa Romeo used them in the past to denote whether a vehicle has a front-wheel drive or an all-wheel drive setup and now Maserati is using the designations for the same purpose on their Ghibli and Quattroporte sedans.
