Key takeaways:
Answer-first: The 2020 Audi A3 Sport 40 TFSI FWD Premium trim originally carried a starting MSRP of $33,300, while the S line 45 TFSI quattro AWD Premium started at $36,500. Upgrading to the Premium Plus trim level raised prices to $36,300 for FWD and $39,500 for AWD models, excluding a $995 destination fee.
For the 2020 model year, Audi simplified the A3 sedan lineup by discontinuing both the entry-level Titanium trim and the top-tier Prestige trim. This consolidation left buyers with two primary trim choices: Premium and Premium Plus. The front-wheel-drive configurations were badged as Sport, while all-wheel-drive configurations received the S line designation.
To celebrate the end of this generation's lifecycle, Audi introduced the optional Final Edition package for an MSRP of $800. This package enhanced the interior aesthetic by adding leather front sport seats in either Black or Magma Red with contrast stitching, a three-spoke flat-bottom steering wheel with shift paddles, and puddle lights projecting the Audi beam rings onto the ground.
In the used car market as of July 2026, Kelley Blue Book fair purchase prices show that a well-maintained 2020 A3 Premium sedan retails around $16,500, whereas a S line Premium Plus version in clean condition commands between $17,900 and $20,300. Because the original four-year factory warranty has expired, buying a pre-owned model requires careful vehicle history verification.
| Trim Level | Drivetrain | Horsepower | Original MSRP | Used Price Range (2026) |
|---|---|---|---|---|
| Sport 40 TFSI Premium | FWD | 184 hp | $33,300 | $15,500 - $17,500 |
| Sport 40 TFSI Premium Plus | FWD | 184 hp | $36,300 | $17,000 - $19,000 |
| S line 45 TFSI Premium | AWD | 228 hp | $36,500 | $16,500 - $18,500 |
| S line 45 TFSI Premium Plus | AWD | 228 hp | $39,500 | $17,900 - $20,300 |
Answer-first: The front-wheel-drive 2020 Audi A3 40 TFSI returns an EPA-estimated fuel economy of 27 mpg city, 36 mpg highway, and 30 mpg combined. Choosing the S line 45 TFSI quattro AWD variant reduces efficiency to 22 mpg city, 30 mpg highway, and 25 mpg combined.
Fuel efficiency remains a major selling point for this premium compact sedan, though the choice of drivetrain significantly impacts long-term fuel costs. Official data published on FuelEconomy.gov shows that the front-wheel-drive model requires approximately 3.3 gallons of fuel per 100 miles, whereas the quattro AWD model raises consumption to 4.0 gallons per 100 miles.
Used buyers should note that the A3 Cabriolet (convertible) variant was discontinued for the 2020 model year in the United States, meaning these fuel economy ratings apply exclusively to the sedan body style. FWD models utilize a 13.2-gallon fuel tank, providing an estimated highway range of over 470 miles. In contrast, quattro models are fitted with a larger 14.5-gallon fuel tank to offset their increased fuel consumption, yielding roughly 435 miles of highway range per tank.
Although Audi recommends premium unleaded fuel to achieve the maximum advertised performance ratings, the engine control unit can safely run on regular unleaded gasoline, helping to keep daily refueling costs manageable for used car owners.
Answer-first: The 2020 Audi A3 features a 2.0-liter turbocharged four-cylinder engine tuned to two different outputs. The Sport 40 TFSI FWD variant generates 184 horsepower and 221 lb-ft of torque, while the S line 45 TFSI quattro AWD variant produces 228 horsepower and 258 lb-ft of torque.
Both engine configurations route their power through a seven-speed S tronic dual-clutch automatic transmission. According to technical specifications compiled by Car and Driver, this gearbox provides rapid, seamless shifts, contributing to the A3's sporty character. The FWD version is tuned for efficient commuting and accelerates from zero to 60 mph in a respectable 6.6 seconds.
Stepping up to the S line 45 TFSI with the quattro AWD system unlocks the full performance potential of this compact chassis. The low-end torque peaks at a low 1,600 rpm, allowing the AWD sedan to sprint from zero to 60 mph in just 5.4 seconds. The quattro system actively distributes power between the front and rear axles to optimize grip.

This makes wet weather driving feel incredibly secure.
The chassis handles daily driving duties with poise, delivering a firm but compliant ride. It remains stable on the highway while offering sharp steering response on twisty back roads. For buyers seeking even more performance, the S3 variant raises the output of the 2.0-liter block to 300 horsepower, though it sacrifices fuel efficiency.
Answer-first: The 2020 Audi A3 displays solid used reliability due to its mature MQB architecture, but buyers must verify safety recall status. The NHTSA issued a major safety recall (NHTSA Campaign 21V-198) affecting passenger occupant detection system (PODS) sensors, which can fail and disable the front passenger airbag during a crash.
When shopping for a pre-owned 2020 model, checking the VIN on the official government database is critical. As detailed in the official NHTSA Safety Recall Report 21V-198, a malfunctioning PODS sensor will trigger a persistent "passenger airbag off" warning light on the center console and generate an acoustic alert. Audi dealers are required to perform the necessary recall repairs free of charge.
Aside from this safety recall, the A3 is known to suffer from premature wear on its rear shock absorbers and occasional infotainment software freezes. Regular maintenance is crucial to avoiding expensive mechanical failures. For details on how routine upkeep impacts vehicle lifespan, see our analysis of how many miles Audis typically last. In particular, the S tronic dual-clutch transmission requires a fluid and filter change every 40,000 miles, a service that typically costs between $300 and $500.
In crash evaluations, the 2020 A3 performed well, earning a "Good" rating from the IIHS in passenger-side small overlap testing. Standard driver-assist systems include forward-collision warning and automated emergency braking, though blind-spot monitoring and rear cross-traffic alert were reserved for the Premium Plus trim level.
Expert view: The 2020 model year represents the final run of the third-generation (8V) A3. Because Audi skipped the 2021 model year in the United States, this version is highly sought after by buyers who prefer physical climate controls over the touch-screen interface of the redesigned 2022 model.
Note: A comprehensive pre-purchase inspection by an independent European vehicle specialist is highly recommended, as suspension repairs or turbocharger issues can easily exceed $1,500 if deferred maintenance is present.
Answer-first: The 2020 Audi A3 is an ideal used purchase for single professionals or couples wanting an agile, fuel-efficient commuter car with premium cabin materials. However, its tight rear cabin and limited trunk capacity of 12.3 cubic feet in FWD models (reducing to 10.0 cubic feet in AWD models) make it a poor fit for families.
When compared to key segment competitors like the Mercedes-Benz A-Class 2020 and the BMW 2-Series Gran Coupe 2020, the Audi stands out for its straightforward ergonomics and balanced ride. The Mercedes offers a more modern digital layout, while the BMW provides a slightly larger trunk but a more polarizing exterior design.

For used buyers, the cargo capacity of the A3 is a major consideration. The packaging of the quattro AWD rear differential eats up significant space beneath the trunk floor, shrinking cargo volume from 12.3 to just 10.0 cubic feet.
When new, the 2020 Audi A3 started at an MSRP of $33,300 for FWD and $36,500 for quattro AWD. In 2026, used market pricing typically ranges from $16,500 for a Premium FWD model up to $20,300 for a clean Premium Plus AWD sedan with low mileage.
The front-wheel-drive Sport 40 TFSI achieves an EPA rating of 30 mpg combined (27 city / 36 hwy). The all-wheel-drive S line 45 TFSI quattro receives a lower EPA estimate of 25 mpg combined (22 city / 30 hwy) due to drivetrain weight.
The 2020 Audi A3 earns average to above-average reliability marks. While the engine and transmission are durable, owners should watch out for infotainment glitches, suspension wear, and ensure that the critical NHTSA passenger occupant airbag recall has been completed.
The 2020 A3 is highly safe, earning "Good" ratings in key IIHS crashworthiness categories. Standard safety equipment includes forward-collision warning and automated emergency braking, though advanced driving aids require the Premium Plus trim level.
The 2020 A3 is equipped with a 2.0-liter turbocharged four-cylinder engine. FWD Sport models produce 184 horsepower and 221 lb-ft of torque, while AWD S line quattro models generate 228 horsepower and 258 lb-ft of torque.
