Audi’s next gasoline-powered midsize luxury sedan will wear the number 6 after all.

Audi announced Feb. 3 that it is reversing its naming convention that would have seen even numbers given to electric vehicles and odd numbers to fuel-burning vehicles.

The automaker already began the new naming convention change when it released the successor to its A4 series of compact luxury cars, but named A5.

Now, the German automaker announced its upcoming gasoline-burning midsize luxury car will be called the A6, not A7 as it would have been called had the new naming convention stuck around. The upcoming A6 will be revealed on March 4.

“This decision is the result of intensive discussions and also follows the wishes of our customers as well as feedback from our international dealers,” said Marco Schubert, member of the board of management for sales and marketing at Audi AG, in a news release. “Our nomenclature now provides all customers worldwide with an intuitive orientation in our portfolio. We choose the names of our models in a way that reveals size and positioning at first glance.”

The letter A will continue to signify cars, or what the company calls low-floor vehicles, while the letter Q will refer to SUVs, or high-floor vehicles. The number that follows the letter will be used for a clear vehicle classification independent of powertrain type, Audi said. Essentially, the bigger the number, the bigger the vehicle.

Audi said all-electric models can share the same combination of letters and numbers with combustion-engine vehicles. The vehicle names will be followed by a powertrain code, which already exists today. So, e-tron stands for all-electric vehicles, TFSI e for plug-in hybrid models, TFSI for gasoline models and TDI for diesel models.

As to what happens to the A5, which was previously named A4, Audi said there are no retroactive name changes planned for models already on sale.
