Audi A3 vs. S3 differences: more than meets the eye
The compact class is gaining popularity in the U.S. as consumers seek more affordable options amid steep prices. For those seeking luxury within this segment, Audi’s A3 and S3 are go-to options, offering solid looks, performance, and efficiency. While both models appear strikingly similar, there are key differences between the two worth considering before you commit to an option.

1. There’s a clear winner on the power front
If you’re prioritizing power, look toward the 2025 Audi S3. This compact sedan’s 2.0-liter turbocharged inline-four engine, paired with a seven-speed dual-clutch automatic transmission, delivers 328 horsepower and 295 pound-feet of torque. By comparison, the 2025 Audi A3’s 2.0-liter turbocharged inline-four engine, which also works alongside a seven-speed dual-clutch, produces 201 horsepower and 236 lb-ft of torque. If power isn’t a top priority, both models have standard all-wheel drive, narrowing the performance gap.
2. The S3’s suspension is more dynamic
The 2025 Audi S3 features a new standard rear torque splitter and swivel bearing suspension, optimizing lateral dynamics, traction, and dynamic stability. The 2025 S3 further distinguishes itself with a standard S sport suspension, lowering the body by 15 mm compared to the A3. The optional S Sport suspension package for the 2025 S3 features adaptive dampers tuned for the torque splitter and respective drive mode. Subsequently, you’ll experience more confident handling, especially during instances like cornering. In contrast, the A3’s suspension is more comfort-oriented.

3. The A3 has more styling tweaks for 2025
Both the Audi A3 and S3 received exterior refreshes for their 2025 production year, with similarities such as more prominent rear diffusers, but the A3’s updates are more pronounced. Differences in the 2025 A3’s exterior include a new, frameless front grille, LED headlights and taillights, and laser-etched B-pillar badging. Drivers also receive two new wheel designs. For the 2025 S3, headlight and taillight designs are essentially the same, but body-colored elements now enclose the grille.
4. Fans of sportier interiors will prefer the S3
The 2025 A3 and S3 now share the same basic cockpit technology configuration. This setup includes a standard 10.1-inch touchscreen, or an optional 12.3-inch version, a 10.25-inch digital instrument cluster, and ambient lighting with 30 selectable colors. While both models essentially share the same drive modes, the S3 differs slightly with its Dynamic Plus mode, which enables more performance-focused, oversteer-prone driving. The S3 also reflects its performance with sportier interior elements such as available leather with red or gray contrasting stitching and S badges. Both models have received new air vents and a smaller shifter.

5. Expect to pay around $10,000 more for an S3
A 2025 A3 starts at $39,495, and the 2025 S3 holds a $49,995 base price. However, you’ll receive slightly better mileage with an A3, which gets 24 mpg in the city and 34 mpg on the highway. By comparison, the S3 is capable of achieving 23 mpg on the highway and 31 mpg in the city.
Final thoughts
The differences between these two vehicles are subtle at first glance, but the S3 justifies its extra cost with more power, performance-oriented technology, and a sportier interior. If athletic driving isn’t your primary concern, the A3 could be an excellent option, as it mirrors several of the S3’s updates, receives a few more exterior design tweaks, and offers better mileage. Be sure to test drive each option so you can see for yourself which is the better fit.
