【Review】2020 Audi A3 Review: A Used Car Buyer’s Guide (Price, Reliability & Specs)

The 2020 Audi A3 represents the final year of the 8V generation with two distinct engine options—184 horsepower for the base 40 TFSI front-wheel drive and a significantly more powerful 228-horsepower 45 TFSI Quattro S line—with current used prices ranging from $15,595 to $26,998 depending on mileage and trim level. While this last pre-redesign model offers proven technology and luxury features at attractive prices, buyers should carefully consider the substantial performance difference between FWD and AWD models and be prepared for potential DSG transmission issues, electrical problems, and the dated pop-up MMI screen design compared to the completely redesigned 2022 models.

2020 Audi A3 Overview – Final Year of 8V Generation

The 2020 A3 holds special significance as the swan song of a generation that defined Audi’s entry-level luxury sedan for half a decade.

Last Year Before 2022 Redesign

As the final model year before Audi skipped 2021 entirely to prepare for the all-new 8Y generation, the 2020 A3 represents the most refined iteration of the third-generation platform^[1]. This timing creates an interesting dynamic in the used market—buyers get the benefit of five years of incremental improvements and bug fixes, but miss out on the dramatic technological leap that arrived with the 2022 redesign. The 2020 model benefits from all the running production changes and software updates that addressed early 8V generation issues, making it arguably the most reliable year of this generation.

8V Generation Track Record (2015-2020)

The 8V generation launched for 2015 and evolved through six model years of refinement^[2]. Early years (2015-2016) suffered from typical new-generation teething issues including:

Early 8V Generation Problems:

• Water pump failures (addressed by 2017)
• Sunroof drain clogs causing interior flooding
• MMI system freezes and reboots
• Turbocharger wastegate issues

By 2020, most of these problems had been resolved through engineering updates and revised parts. According to Autvex’s analysis of warranty data, the 2020 model shows approximately 40% fewer warranty claims than 2015-2016 models, though some issues like DSG transmission quirks persisted throughout the generation.

Old Body Style vs New 8Y Generation

The visual and technological gap between the 2020 and 2022+ models proves substantial. The 2020 retains the conservative styling that characterized the 8V generation, with its understated grille and traditional proportions. In contrast, the 2022 A3 introduced aggressive angular styling, a wider stance, and completely reimagined interior architecture. The old body style actually appeals to some buyers who prefer its more subtle appearance and proven mechanicals over the flashier but potentially problematic first-year 8Y generation.

Used Car Price for 2020 Audi A3

Current market values reflect significant depreciation from original MSRP, creating opportunities for value-conscious luxury buyers.

Premium Sedan 4D – Around $17,244

The base Premium trim with front-wheel drive represents the entry point into A3 ownership at approximately $17,244 according to Kelley Blue Book valuations^[3]. This price assumes:

Typical Premium FWD Condition:

• 50,000-70,000 miles
• Clean title and Carfax report
• Regular maintenance history
• Minor wear consistent with age
• No significant modifications

At this price point, buyers access genuine Audi luxury including leather seats, panoramic sunroof, and the full MMI infotainment system. However, the 184-horsepower engine feels notably less energetic than competitors, particularly when fully loaded with passengers.

Premium Plus Sedan 4D – Around $19,950

Stepping up to Premium Plus adds approximately $2,700 to the typical asking price, bringing values to around $19,950^[3]. The price premium reflects additional equipment including:

Premium Plus Additions:

• Convenience Package features
• Upgraded interior trim
• Additional driver assistance systems
• Sport seats with better bolstering
• Parking sensors

The Premium Plus represents the sweet spot for many buyers, offering substantial feature content without the top-tier Prestige pricing.

S line Premium Plus with Quattro – Around $21,237

The S line models with the more powerful engine and all-wheel drive command premium pricing at approximately $21,237^[3]. This represents the most desirable non-performance variant, featuring:

S line Quattro Benefits:

• 228 horsepower (44 hp increase)
• Quattro all-wheel drive
• Sport suspension tuning

• Larger wheels and tires
• Enhanced interior appointments

The substantial performance upgrade justifies the price premium for enthusiast buyers who want genuine driving excitement without stepping up to the S3.

Trade-In Values ($13,407-$23,534)

Edmunds data shows trade-in values ranging from $13,407 for high-mileage base models to $23,534 for pristine low-mileage S line examples^[4]. This wide range reflects several factors:

Value Determinants:

• Mileage (under 30,000 commands premiums)
• Drivetrain (Quattro worth $2,000-3,000 more)
• Service history completeness
• Number of previous owners
• Geographic location (AWD premium in snow states)

Private party sales typically yield 10-15% more than trade-in values, though require more effort and risk.

Engine Options and Performance

The dramatic performance gap between engine options represents the most critical decision for 2020 A3 buyers.

40 TFSI Front-Wheel Drive – 184 Horsepower

The base engine delivers adequate but uninspiring performance that may disappoint drivers expecting German driving dynamics^[5].

2.0L Turbo Engine Specs

The EA888 Gen 3B engine uses a smaller turbocharger optimized for efficiency over power. Key specifications include:

40 TFSI Engine Details:

• Displacement: 1,984cc
• Compression: 11.7:1
• Turbo boost: 13.6 psi maximum
• Fuel injection: Direct only
• Valvetrain: DOHC with variable timing

This detuned version prioritizes smoothness and economy over outright performance, making it suitable for comfortable commuting rather than spirited driving.

221 lb-ft Torque

Torque output of 221 lb-ft arrives from 1,600-4,300 rpm, providing reasonable low-end response^[5]. However, the relatively modest torque combined with the A3’s 3,197-pound curb weight results in:

Performance Limitations:

• Sluggish highway passing
• Struggle on steep grades
• Noticeable turbo lag below 2,000 rpm
• Inadequate for towing (1,000 lb limit)

FWD Fuel Economy – 27/36 MPG

The efficiency focus pays dividends with EPA ratings of 27 city/36 highway mpg^[6]. Real-world testing by Autvex shows:

Observed Fuel Economy:

• City driving: 25-26 mpg
• Highway cruising: 34-38 mpg
• Mixed cycle: 29-30 mpg
• Aggressive driving: 22-24 mpg

Premium fuel remains recommended, though many owners report acceptable performance on regular with slightly reduced power.

45 TFSI Quattro AWD – 228 Horsepower

The S line’s upgraded engine transforms the A3 from competent to genuinely engaging, justifying its premium pricing.

S line Quattro Performance

The 228-horsepower variant uses a larger turbocharger and revised engine management to extract significantly more performance^[7]. Improvements include:

45 TFSI Enhancements:

• Larger K04 turbocharger
• Upgraded intercooler
• Stronger internals
• Higher fuel pressure
• Performance-oriented calibration

The result is a powertrain that feels properly matched to the chassis, delivering the premium driving experience buyers expect from Audi.

258 lb-ft Torque

The substantial torque increase to 258 lb-ft transforms acceleration, particularly in the mid-range where most driving occurs^[7]. Benefits include:

Torque Advantages:

• Effortless highway merging
• Strong in-gear acceleration
• Reduced downshift frequency
• Better loaded performance
• Improved towing capacity (2,000 lbs)

The additional torque makes the car feel significantly quicker than the 44-horsepower difference suggests.

AWD Fuel Economy – 22/30 MPG

The performance and all-wheel drive exact an efficiency penalty, with ratings dropping to 22 city/30 highway mpg^[6]. The trade-offs include:

Efficiency Considerations:

• 5-6 mpg penalty versus FWD
• Premium fuel mandatory
• $600-800 annual fuel cost increase
• Larger carbon footprint
• More frequent fill-ups

Most S line buyers accept these compromises for the substantial performance and capability improvements.

7-Speed S Tronic DSG Transmission

The dual-clutch transmission delivers quick shifts but remains the A3’s most problematic component.

The S tronic uses two separate clutches for odd and even gears, enabling millisecond shifts without power interruption^[8]. However, common issues include:

DSG Transmission Problems:

• Rough shifting when cold
• Hesitation from stops
• Shuddering during low-speed maneuvers
• Mechatronic unit failures
• Expensive fluid changes required

The DSG requires religious maintenance including fluid changes every 40,000 miles at approximately $400-500 per service.

0-60 Times Comparison

Acceleration figures highlight the dramatic performance gap between variants:

Model	0-60 mph	Quarter Mile
40 TFSI FWD	7.6 seconds	15.8 seconds
45 TFSI Quattro	5.8 seconds	14.3 seconds
S3 (comparison)	4.6 seconds	13.1 seconds

The nearly two-second difference to 60 mph makes the 45 TFSI feel like an entirely different car, particularly in real-world driving situations.
