Audi is expected to launch the 2021 RS3 model offering incredible performance and other features in late 2020 or early 2021. It is one of the best-selling sedans world-wide. Its previous generation models had terrific sales, urging Audi to facelift the new RS3. The brand has confirmed that RS3 sedan will receive a facelift with more trims, interior and safety features on offer but those are just speculations while reality could be much different. With a price tag under 60,000USD, it is currently offered in only one trim level.

Infiniti Q60 Redsport, BMW M2 Competition and Mercedes-AMG CLA 45 continue to be its rivals with Mercedes-AMG CLA 45 being its major nemesis. The price of the new model is expected to be the same as the previous year. In addition, choosing between trims should be pretty easy as there is only one trim and it offers everything you can get in a Compact Luxury Sports Car. Here is our take on the 2021 Audi RS3 Sedan that is soon going to be on sale in the US market.

2021 Audi RS 3 Maintenance, Reliability and Warranty

Audi RS3 is included in the list of the best high-performance sedans being sold in the market. Every Audi variant is prone to minor issues. Like every other Audi car, RS3 also has to be maintained regularly for a good driving experience. With a decent warranty, maintenance and repair costs should not dent your pocket but still what Audi has to offer is better than its rivals. 

Reliability and Ownership Costs

J.D. Power report and customer reviews are two important references that every customer relies on. Audi RS3 has not been rated by J.D. Power for two generations. RS3 requires frequent maintenance all through its lifespan. The average repair cost of Audi cars is estimated at $300 per year. But the costs can be reduced through warranty and scheduled maintenance options. Every Audi service center is advanced enough to solve any unexpected problems.

2021 Audi RS3 costs $56,200 on average. The RS3 is one of the Audi cars that has a very high depreciation rate. After the first year, the RS3 is expected to lose 25 percent of its value but that number goes down as the year’s progress. Audi’s are among the most valuable and reliable cars in the market and the same holds true for the RS3. 2020 Audi RS3 had one safety recall defect due to the deactivation of airbags. Audi offers only one year of complimentary scheduled maintenance and infrequent free repairs. So, if you encounter a repair situation, be warned it’s going to be expensive.


Audi RS3 offers competitive limited warranty and powertrain warranty. It offers good 24-hour roadside assistance for 4 years or unlimited miles.



Limited warranty

4 years/ 50,000 miles; whichever is earlier

Powertrain warranty

4 years/ 50,000 miles; whichever is earlier

24-hour roadside assistance

4 years/ unlimited miles; whichever is earlier

Audi RS3 offers a similar basic warranty as BMW M2 Competition and Mercedes-AMG CLA 45. None of the rivals can beat Infiniti Q60 Redsport in powertrain warranty of six-year/70,000-mile. Complimentary maintenance warranty 1 year or 10,000 miles is poor for Audi. BMW offers the same service for 36 months/36,000miles for M2 competition.

Miles per Dollar

In this we will be factoring the annual maintenance cost and how many miles the car runs on average in a year. We do not have an annual maintenance estimate for the 2021 mode and hence it has to say exactly how much miles per dollar u get. However, based on the average annual maintenance we are expecting the 2021 model to give roughly around 45 miles for a dollar. 

2021 Audi RS 3 Buying Advice

Audi RS3 comes only in one trim. We recommend you opt for the Dynamic package along with adaptive exhaust but keep the standard magnetic damping. By spending $2,000 on the navigation package and the driver assistance package, and the addition of all safety features keeps the sedan under $60,000. If money is not a constraint, then a lot of exterior and luxurious interior options can be added to the build. Also, when compared to its rivals Audi RS3 a stand top in performance and safety features and is reliable.

Is buying a car Audi RS3 a good idea?

As stated earlier, Audi cars need maintenance and its excessive costs can be halted when in warranty period. So, buying a used car reduces the warranty period and also increases the chances of frequent maintenance. It is better to go for the fresh one with all the fresh parts.

2021 Audi RS 3 Engine and Performance


The 2021 Audi RS3 Sedan will get a more turbulent engine than its previous model. A 2.5-liter TFSI turbocharged five-cylinder can be found beneath the hood similar to its predecessor but in an updated form.

This engine is powerful enough to generate a power of 414 Hp and a torque of 369 lb.-ft. A performance version will be unleashed later to produce a boosted power of 444 Hp.

The beast under the hood along with 7 speed S Tronic dual-clutch automatic transmission coupled to the Quattro all-wheel-drive system, adaptive electronic power steering and adjustable dampers work in chorus directly to put forward a delightful journey. 2021 Audi RS3 Sedan has a powerful engine to beat its rivals in the power field. BMW M2 Competition costs more than others but delivers an engine which generates more torque than any other competitors.

2021 Audi RS3 Sedan Acceleration and Braking Performance

2021 Audi RS3 Sedan is expected to have better acceleration than its forerunner. The acceleration figures are not yet disclosed. The 2020 Audi RS3 Sedan has a robust engine making it dash from 0-60 mph in 3.9 seconds. It just takes 12.1 seconds to cover a quarter mile.

Moving on to the braking department, ventilated eight-piston front disc brakes of 14.6 inch and ventilated rear disc brakes of 12.2 inch helps to brake from 60 MPH to a standstill in just 109 ft. 2021 Audi RS3 Sedan is expected to have slight improvements in braking performance.

Although Audi RS3 Sedan and Mercedes-AMG CLA 45 have similar top speed, RS3 beats its rivals in the acceleration department. It takes very little time to cover 0-60 MPH and quarter mile when compared with its adversaries. 

2021 Audi RS 3 Fuel Economy


2020 Audi RS3 Sedan has an EPA estimated mileage of 23 MPG combined. Its mileage figures are not impressive but with a full fuel tank, RS3 Sedan can cover a maximum of 533 miles to overcome the other downside.

Despite the fact that Infiniti Q60 Redsport has a large fuel tank, its range is not enough to beat Audi RS3. Audi RS3 offers a long-range with its large fuel tank. But its fuel economy figures are poor when compared with the most efficient Mercedes-AMG CLA 45.

2021 Audi RS 3 Interior


Audi RS3 Sedan offers luxurious and classy interiors that touches the heart of every car enthusiast. RS badges are engraved on the gear shift lever and steering wheel. Spherical AC vents, ambient LED interior lighting, elegant dashboard, leather or Alcantara steering wheel, door-mounted wing mirrors, dual-zone climate control and carbon fiber inlays are few highlights.

2021 Audi RS 3 Sedan Front Seat

Moving on to the seats, RS3 Sedan offers room for 5 occupants. Nappa leather sports bucket seats with diamond stitching in red or Rock Gray thread depending on your choice gives the seats a sportier sensation. If you opt for Red diamond stitching, $750 will be added and also the silver air vents will be replaced by a red one. RS3 Sedan provides sufficient front and rear legroom. The seats are manually adjustable and also have electrically controlled lumbar support. The front seats are heated but the rear seats are not. Even though it is a 5-seater sedan, it will be a little bit tight if you pack 3 adults in the rear seats.

The RS3 has a trunk space 10 cubic feet which are extendable by splitting and folding rear seats. RS3 also has ample space for holding large water bottles, 2 cupholders to be shared among front and rear occupants and a small-sized glove box. Audi RS3 Sedan and Mercedes-AMG CLA 45 offer 5 seats while the M2 and Q60 Redsport can only seat 4. All the rivals provide sufficient rooms in both front and rear. In terms of cargo space, Audi RS3 Sedan has the lowest trunk capacity while M2 Competition has the highest –13.8 cu-ft.

How is the 2021 Audi RS3 Sedan’s infotainment system?

2021 Audi RS3 holds the same infotainment features and technologies as its predecessor. To display information on performance, travel, entertainment and status of the vehicle, a 12.3-inch display is presented in the virtual cockpit. A 7-inch touch screen display is also included with standard Apple CarPlay and Google Android Auto interface. Another main highlight feature is the MMI touch with handwriting-recognition technology.
