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.
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.
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.
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:
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.
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.
Current market values reflect significant depreciation from original MSRP, creating opportunities for value-conscious luxury buyers.
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:
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.
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:
The Premium Plus represents the sweet spot for many buyers, offering substantial feature content without the top-tier Prestige pricing.
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:
The substantial performance upgrade justifies the price premium for enthusiast buyers who want genuine driving excitement without stepping up to the S3.
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:
Private party sales typically yield 10-15% more than trade-in values, though require more effort and risk.
The dramatic performance gap between engine options represents the most critical decision for 2020 A3 buyers.
The base engine delivers adequate but uninspiring performance that may disappoint drivers expecting German driving dynamics[5].
The EA888 Gen 3B engine uses a smaller turbocharger optimized for efficiency over power. Key specifications include:
40 TFSI Engine Details:
This detuned version prioritizes smoothness and economy over outright performance, making it suitable for comfortable commuting rather than spirited driving.
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:
The efficiency focus pays dividends with EPA ratings of 27 city/36 highway mpg[6]. Real-world testing by Autvex shows:
Observed Fuel Economy:
Premium fuel remains recommended, though many owners report acceptable performance on regular with slightly reduced power.
The S line's upgraded engine transforms the A3 from competent to genuinely engaging, justifying its premium pricing.
The 228-horsepower variant uses a larger turbocharger and revised engine management to extract significantly more performance[7]. Improvements include:
45 TFSI Enhancements:
The result is a powertrain that feels properly matched to the chassis, delivering the premium driving experience buyers expect from Audi.
The substantial torque increase to 258 lb-ft transforms acceleration, particularly in the mid-range where most driving occurs[7]. Benefits include:
Torque Advantages:
The additional torque makes the car feel significantly quicker than the 44-horsepower difference suggests.
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:
Most S line buyers accept these compromises for the substantial performance and capability improvements.
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:
The DSG requires religious maintenance including fluid changes every 40,000 miles at approximately $400-500 per service.
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.
The 2020 A3's reliability represents a mixed bag with some predictable problem areas requiring attention.
Owner experiences vary dramatically, with some reporting trouble-free ownership while others face frequent dealer visits. RepairPal rates the A3 at 2.5 out of 5 stars for reliability, ranking it 23rd out of 36 luxury compact cars[9]. Common patterns include:
Reliability Patterns:

Value Factors:
According to Autvex projections, a 2020 A3 purchased today for $20,000 will likely be worth $12,000-14,000 by 2028.
Start your search by determining whether the base 184-horsepower engine suffices or if the 228-horsepower S line Quattro is worth the premium—test drive both as the performance difference is dramatic. Use online tools to verify all recalls have been completed, particularly the fuel pump and airbag issues that could affect safety. Schedule pre-purchase inspections at Audi specialists who understand DSG transmission health checks and can scan for stored fault codes.
Request maintenance records specifically looking for 40,000-mile DSG services, as skipped intervals virtually guarantee expensive failures. Budget for extended warranty coverage if purchasing from dealers, or set aside $2,000-3,000 annually for maintenance and repairs if buying privately. Compare insurance quotes as the A3's luxury classification and turbocharged engine can increase premiums 20-30% versus mainstream sedans.
Consider whether the dated technology bothers you by spending time with the pop-up MMI screen during test drives—some find it charming while others consider it unacceptable. Evaluate whether spending $5,000-8,000 more for a 2022+ model with modern technology and fewer miles makes sense for your situation. Research independent German specialists in your area as they typically charge 30-40% less than dealers for routine maintenance while maintaining quality.
Finally, strongly consider the 45 TFSI Quattro S line over base models even at the $4,000-5,000 premium, as the performance improvement transforms the driving experience and commands better resale values. According to Autvex market analysis, S line Quattro models retain value approximately 15% better than base FWD variants over five years of ownership. If the 2020's reliability concerns worry you, consider certified pre-owned 2023+ models that include warranty coverage and have resolved most first-generation 8Y issues.
