Audi’s naming scheme can be a little daunting, but it’s actually fairly simple. The breakdown is as such:
- A models are the base models
- S models are sportier, or otherwise offer more luxury
- RS stands for Rennsport, the top of the line for their class
- Q models are SUVs and Crossovers.
The numbers 3 through 8 denote differences in the vehicles; for instance, an A8 is a larger, more powerful car than the A3.
Each vehicle is complemented by Audi's trim styles (available on most vehicles). They are:
- Premium Plus
Each step up adds more luxury and tech features.
The 3 is the quintessential entry-level Audi. Starting at $33,300, this model has a few options that can meet any consumer lifestyle.
Across all 3-series models, there are two engine choices. They are the:
- Turbocharged two-liter V4 (inline)
- Turbocharged 2.5L V5 (inline)
The A3 and S3 both have a turbocharged two-liter V4. The RS3 is the only 3-series with the 2.5L V5.
Moving up to the A4 and S4, we find a more rugged vehicle. What makes it a more interesting vehicle is the addition of the three-liter V6 engine found in the S4 models. We can also note that the A4 comes in a wagon variant that can be taken off-road.
Starting at only $39,100, the A4 and S4 are definitely cars that make a statement on the road.
We can sum up the A5 as an updated A4, as it uses the same engine as the 2020 model. The A5 Sportback, coupe, and cabriolet models all use the same engine as the A4. Moving up to the S5 however, the Sportback, coupe, and cabriolet models all use the S4's three-liter V6.
2021 RS5 models have yet to be announced with updated specifications.
Starting at $41,800, the 5-series is one of the top luxury small cars available today.
In 2019, the A6 went through a redesign that brought it to the top of the midsize luxury sedan category. The A6 has that signature Audi look, aggressive yet subtle. The S6 brings an engine upgrade, too. It sports a 2.9-liter V6 twin-turbo, which coincidentally is the same engine found in both the RS5 and S7.
An engine of this caliber brings performance to match. The Audi S6 boasts a horsepower rating of 444 and a 4.4 second zero to sixty time.
The A6 starts at $54,900 and comes in the three signature Audi trim packages that bring something for everybody. The S6 follows the same pattern. Its MSRP is $74,400, and the price goes up depending on the trim package chosen.
Much like its subordinate, the A7 is basically an A6 Sportback if it existed in a 2021 model. The S7 follows the same pattern and brings performance to match. Along with a redesign in 2019, the 2021 S7 brings the signature Audi look to a car that is both functional and aesthetically pleasing.
The RS7 for 2021 sees a big engine upgrade to a twin-turbo four-liter V8 that boasts an incredible 591 horsepower and a 3.5 second zero to sixty time.
The A7 starts at $69,200. The S7 brings the starting MSRP to $84,400, and the RS7 starts at $114,000.
The 2021 A8 brings a certain sophistication to the surrounding air. The car balances fine lines and details. The A8 comes standard with a three-liter V6, it brings 453 horsepower to the table and has a 4.5 second zero to sixty time.
The S8 ups the ante with a twin-turbo four-liter V8 engine with a blistering 3.8 second zero to sixty time and 563 horsepower.
The A8 starts at $85,200 and the S8 brings the starting MSRP to $130,900.
