Audi announces new two-digit naming system

Once upon a time, model numbers indicated a car’s engine displacement. A BMW 328i had a 2.8-liter engine, a Mercedes S500 had a 5.0-liter V8, etc. Then engine downsizing happened. Since a new car couldn’t have a lower and thus seemingly inferior number than its predecessor, we ended up with model numbers that represented nothing but an incremental trip up the heirarchy.
