The 2023 Audi S3 hits 60 mph in 4.3 seconds, returns better-than-EPA fuel economy in real-world driving, and wraps everything in a compact, luxury package starting around $45,000[1]. For buyers who want GTI-level fun with quattro grip and Audi refinement, this compact sport sedan punches well above its curb weight.
Audi's entry-level S badge often gets overlooked. The RS 3 grabs headlines with its five-cylinder soundtrack, and the Golf R gets all the hot-hatch love. But the S3 occupies a sweet spot: genuine performance without the insurance premiums or attention-grabbing exhaust note that announces itself at every stoplight.
Part of the third-generation A3 platform introduced for 2022, the 2023 model year brought adaptive cruise control as an option for the base Premium trim and a wireless charging pad in the Convenience package[2]. These aren't revolutionary changes, but they address previous gaps in the feature list.

That turbocharged 2.0-liter four-cylinder doesn't sound exotic, but the numbers tell a different story. Car and Driver recorded a 4.3-second sprint to 60 mph at the test track, with the quarter-mile falling in 12.9 seconds at 108 mph[1]. Real talk: that's quicker than many cars costing twice as much.
The power delivery feels perky and eager, though Comfort mode introduces noticeable turbo lag off the line[1]. Dynamic mode sharpens everything. Steering weight increases progressively with lock, and some road texture actually makes it through to your fingertips—a rarity in modern electric power steering setups[3]. The chassis and suspension tuning represent a step forward from the previous generation according to MotorTrend's first drive[4].
Here's the catch: the steering feels heavy but lacks feedback. You'll point the car confidently, but don't expect the tactile connection of a Porsche Cayman. It's composed, not communicative.
The EPA rates the S3 at 23 mpg city, 32 highway, and 26 combined on premium fuel[3]. What the spec sheet doesn't tell you? Most testers beat those numbers. Autoweb averaged 32 mpg during their weeklong evaluation, with highway cruising registering around 40 mpg on the trip computer[5]. The Drive reported 28 mpg over 600 miles of spirited driving—clearly exceeding the EPA's math[3].
Your mileage will vary if you have a permanent lead foot. But point the S3 onto an open freeway and let adaptive cruise take over, and fuel bills stay surprisingly light for a 306-hp all-wheel-drive sedan.
| Trim | MSRP (When New) | Current Market (2025) |
|---|---|---|
| Premium | ~$45,000 | $31,000–$34,000 |
| Premium Plus | ~$47,000 | $33,000–$36,000 |
| Prestige | ~$50,000 | $35,000–$39,000 |

Used 2023 S3 models now average around $38,900 nationwide, with clean examples starting near $32,000 depending on mileage and condition[7][8]. That's significant depreciation from MSRP, making certified pre-owned a compelling entry point into Audi's performance lineup. If you're cross-shopping other Audi sports cars, the S3 offers strong value in this segment.
| Spec | 2023 Audi S3 | VW Golf R | Mercedes-AMG A35 |
|---|---|---|---|
| Horsepower | 306 hp | 315 hp | 302 hp |
| Torque | 295 lb-ft | 310 lb-ft | 295 lb-ft |
| 0-60 mph | 4.3 sec | 4.5 sec | 4.7 sec |
| Combined MPG | 26 | 25 | 26 |
| Starting MSRP | ~$45,000 | ~$44,000 | ~$47,000 |

The Golf R shares the S3's platform and powertrain but costs roughly $4,000 less[9]. You're paying the Audi premium for the badge, slightly richer interior materials, and sedan-over-hatch practicality. The Mercedes-AMG A35 brings German rival glamour but falls behind in straight-line acceleration tests.
Where the S3 genuinely separates itself: ride quality and refinement. Autoweb noted it rides and handles with slicker sophistication than the Cadillac CT4, while delivering more luxury-grade electronics[5]. The Audi is also the only sedan in this trio with an adult-friendly backseat.
Common concerns with the A3/S3 platform include DSG transmission issues (rough shifting, hesitation) and electrical quirks related to sensors and infotainment[10]. Some owners report illumination of various warning lights, often related to emissions or airbag sensors[10]. Worth noting: certain 2020-2023 models faced a recall (R/2023/254) for an electrical connector issue with the interior fuse carrier[10]. Before purchasing, check which Audi A3 years to avoid for additional context.
That said, these aren't widespread failures. The current-generation platform doesn't carry the reliability baggage of earlier turbocharged Audis. If you're comparing the 2023 Audi A3 to the S3, the performance upgrade justifies the price bump for enthusiast drivers.
The A3 platform (which underpins the S3) earned IIHS TOP SAFETY PICK recognition[11]. Front crash prevention with standard Pre Sense Front rates "Superior" for vehicle-to-vehicle collision avoidance, stopping the car completely in both 12 and 25 mph tests[12]. Pedestrian detection rates "Advanced"—not perfect, but solid[12]. NHTSA crash test ratings for the 2023 S3 specifically weren't available at publication.
What Works
What Doesn't
The RS 3 brings 401 hp from a characterful five-cylinder and sharper driving dynamics. But it costs $20,000+ more. If you want performance that handles daily commutes without drama, the S3's 306 hp delivers. Choose the RS 3 only if the extra power and exhaust note justify the premium. For SUV alternatives in the Audi lineup, explore the 2023 Audi SQ5.
They share a platform and powertrain. The Golf R offers 315 hp (9 more than the S3) and costs about $4,000 less. The S3 counters with a more refined interior, sedan practicality, and the Audi badge. Performance is nearly identical in real-world driving[9]. Your decision comes down to whether hatchback utility or sedan elegance matters more.
