Welcome to Brand Breakdown, a series of comprehensive yet easy-to-digest guides to your favorite companies, with insights and information you won’t find on the average About page.

We’re huge fans of Audi’s current and past products — the company blends high technology with solid performance and styling that is handsome if a bit reserved. Most famously, the brand is known for its near-ubiquitous all-wheel-drive. Here’s everything you need to know to understand, decipher and shop Audi’s current model lineup.

Audi History

Audi is a German luxury car manufacturer based in Ingolstadt and owned by Volkswagen AG. The Audi name dates back to 1910, but VW consolidated multiple companies into the modern “Audi” in 1969. Audi made its name in motorsport with the four-wheel drive rally champion Audi Quattro in the early 1980s. Volkswagen has positioned Audi as its upmarket competitor for Mercedes-Benz and BMW.

How Audi Names its Cars

Audi follows a simple naming format, for the most part, employing letters and numbers. Base models have an “A” designation. Sportier luxury models get an “S.” The sportiest “RennSport” models get an “RS.” Audi uses “Q” for its SUV line. The now-extinct TT and R8 existed outside that nomenclature. Audi employs “E-Tron” for its electric cars.

Audi pairs letters with numbers 3 through 8 in America. Higher numbers can mean different things. It could mean a larger, more powerful car, as in the A8; it could mean a near-identical car with a different body style, as in the Q7 and Q8. (Whatever the distinction, the higher number will be more expensive.)

Most Audi models offer Premium, Premium Plus and Prestige trim levels, with each level adding tech and luxury features.

audi e tron gtAudi

The E-Tron GT is Audi’s electric sports sedan, which is new for 2021. It shares the J1 electric platform with the Porsche Taycan. GT stands for gran turismo, which means Audi intended the E-Tron GT to provide more ride comfort than an all-out sports car. Still, the E-Tron GT can perform. The base E-Tron GT can deliver up to 522 hp and 472 lb-ft of torque with overboost. The hotter RS E-Tron GT offers a sustained maximum of 590 hp and 617 lb-ft. It can accelerate from 0-60 mph in 3.1 seconds and hit a top speed of 155 mph.
