Nomenclature has been something Audi fans have struggled with, but to be fair the naming scheme from Ingolstadt hasn’t always been particularly straightforward. For example, though ubiquitous as the Coupe GT, there was actually a trim and performance difference between B2 front-drive Coupes and Coupe GTs. Similarly, though U.S. fans often fair to recognize it, the B3 Coupe Quattro was actually the second generation with the name; Europeans enjoyed the option of having a non-turbocharged, non-flared version of the B2 platform which few but the most dedicated U.S. Audi Coupe fans are aware of. Then there’s the name – properly, a capitalized Quattro refers to the aforementioned legend – the model that launched the branding of Audi’s all-wheel drive system. Every subsequent model that followed properly has a lowercase “q” if it sported the optional all-wheel drive. That even goes for models that were only offered in all-wheel drive, such as the V8 quattro. That is, except for the Coupe Quattro, which Audi insisted should also be capitalized. So confusing is the naming scheme that fans have taken to using “Ur” to refer to the Quattro (though proper capitalization would take care of the problem) for not only the original model, but the C4 S4/S6 and I’ve even been seeing it used for TTs, A4s and a few others. It also means that every time one comes up for sale and someone slaps ‘Ur’ in front of it, someone else has to ask what ‘Ur’ means.
But the B3 and B4 Coupe wasn’t just offered in all-wheel drive; there were a long line of optional engines in the Coupe in both two and four wheel drive. However it only came to the U.S. in one configuration – the under-appreciated 7A inline-5 20V motor pushing all four wheels. The B3 ran the second generation of quattro, with the center differential controlled by a Torsen unit and the rear open with an optional, speed limited locking unit. It upped the safety and electronic options to respond to market demands. They were heavy with electronic features including power seats, and passengers enjoyed the confusing safety net known as PROCON-10 – essentially, a series of cables that pre-tensioned seatbelts in the event of a crash. Though the production run of U.S. Coupes was brief at only 2 years and roughly 1700 units, there were many changes over that time. The motor changed ISV valves and computers as well as swapping from a tubular header to a cast-iron unit. Shortly into production, airbags became standard on both the Coupe and sedan models. A rear swaybar was added, along with changes to the hydraulic system. All of these went relatively unseen to consumers, making the only notable change the addition of a glass sunroof to 1991 models. For the most part, these cars came fully loaded with the only options being Pearlescent White Metallic paint and power heated seats, unlike the sedan which despite being fewer in number has much more variety in options.
