Used 2025 Audi S5 for Sale nearWilton, CT

Is the 2025 Audi S5 a good car?

Yes — 5/5 from users and 7.00/10 from expert testing. The model scores 9/10 across Form and function and Technology.

The 2025 Audi S5 is positioned as a redesigned, multi-talented sportback that blends performance, comfort, utility, and the latest technology, with enough room for a family of four. That makes it more versatile than a pure weekend toy, especially if you want something engaging on a favorite back road without giving up everyday usefulness.

The trade-offs are clear: the styling is uninspired, the highway ride can be noisy, and the driver assistance tech is unimpressive. Even so, the car’s strongest points are its fun-to-drive character, useful cargo space, and impressive cabin tech.

Good and great deals account for 26.7% of listings, which gives you some room to shop selectively.

Is the 2025 Audi S5 reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction.

The 2025 Audi S5 is presented as a refined, well-equipped luxury sportback with strong performance and modern technology, and its overall package suggests solid day-to-day usability. The turbocharged V6 is described as a deeply satisfying powerplant with seemingly limitless power, and the car’s cabin and controls are built around a high-tech, premium experience.

Audi also includes a generous trial subscription to connected services, which adds some ownership value up front.

For used buyers, the main long-term risk is that the car’s high-performance hardware and advanced tech may be more expensive to live with if you want to keep it in top shape.

What should I look for when buying a used 2025 Audi S5?

Accident-free inventory is excellent at 97.3% — clean inventory, standard diligence applies.

You should still run a vehicle history report and prioritize a pre-purchase inspection, especially if you’re considering a higher-trim example with more equipment to verify. Focus on overall condition, tire and brake wear, and whether the tech and driver-assistance systems behave as expected on a test drive.

Key things to evaluate:

• Trim level: Premium trim gives you the core S5 experience, including the liftback body style, large cargo area, premium cabin materials, and the full standard driver-assistance suite. Premium Plus and Prestige add more luxury and convenience, but the base trim already covers the essentials well.
• Powertrain: The S5 uses a turbocharged 3.0-liter V6 with 362 horsepower and 406 pound-feet of torque, paired with a seven-speed dual-clutch automated manual transmission and standard Quattro all-wheel drive. It is tuned for strong acceleration and enthusiastic driving, but it is also heavier than before and not especially fuel-efficient.
• Safety package: Every Premium includes forward collision warning, automatic emergency braking, lane departure warning, blind-spot monitoring, rear cross-traffic alert, adaptive cruise control, automatic high-beam headlights, traffic sign recognition, front and rear parking sensors, safe exit warning, and Emergency Assist. Premium Plus and Prestige add Adaptive Cruise Assist, which brings lane-centering, plus a surround-view camera system and Park Assist Plus.
• Infotainment: The cabin centers on an 11.9-inch digital instrument display and a 14.5-inch MMI touchscreen. Prestige adds a 10.9-inch passenger screen, and Premium Plus adds a head-up display and a 20-speaker Bang & Olufsen sound system with 3D audio. Wireless smartphone integration is not stated here, so verify the exact connectivity setup on the car you’re considering.
• Fuel efficiency: The official EPA combined rating is 22 mpg, and the test loop returned 21.8 mpg.

Which 2025 Audi S5 trim should I buy?

The 2025 Audi S5 is offered in 3 trim levels: Premium, Premium Plus, and Prestige.

Here's the short version:

• Premium: This is the trim to start with if you want the S5’s core strengths without paying for extras you may not need. You still get the turbo V6, Quattro AWD, the liftback body style, the large cargo area, and the full standard safety suite, so it delivers the essential S5 experience.
• Premium Plus: This is the best-value trim for many shoppers because it adds meaningful everyday upgrades, including Adaptive Cruise Assist, a surround-view camera system, Park Assist Plus, a head-up display, and the 20-speaker Bang & Olufsen audio system. If you want more convenience and tech without going all the way to the top trim, this is the one to target.
• Prestige: Choose this if you want the most upscale version of the S5. It adds the front passenger touchscreen, adaptive-damping sport suspension, and the most fully loaded cabin presentation, making it the right pick if you care most about luxury and tech.

Adaptive Cruise Assist is standard only on Premium Plus and Prestige, while the base Premium keeps the broader standard safety suite without that lane-centering function.

Is now a good time to buy a used 2025 Audi S5?

This looks like a moderate, selective buyer’s market, so you can shop carefully rather than rush.

• Deal availability: 26.7% of listings are priced as good or great deals.
• Inventory: There are 146 listings available.
• Clean inventory: 97.3% of listings are accident-free.

If you find a listing below $58,487, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2025 Audi S5 safe?

It earns Good ratings from IIHS testing, and the standard safety equipment is extensive.

It earns a 4/10 safety score from our experts.

Every 2025 Audi S5 Premium boasts forward collision warning, automatic emergency braking, lane departure warning, blind-spot monitoring, rear cross-traffic alert, adaptive cruise control, automatic high-beam headlights, traffic sign recognition, front and rear parking sensors, safe exit warning, and Emergency Assist. Premium Plus and Prestige add Adaptive Cruise Assist, which includes lane-centering, along with a surround-view camera system and Park Assist Plus.

The main caveat is the behavior of the lane-assist system: it can feel overly aggressive and inconsistent, and the expert evaluation also noted an unexplainable braking event. That makes the advanced driver-assistance setup less reassuring than the rest of the safety hardware.

Should I buy a 2025 Audi S5 or consider a different year?

If you're weighing the 2025 against nearby model years, here's how to think about it:

Choose the 2025 if:

• 26.7% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 97.3% — clean inventory, standard diligence applies.
• Owners rate it 5/5 — a strong satisfaction signal.
• The redesigned S5 is a multi-talented sportback with thrilling dynamics, impressive Audi Digital Stage technology, and just enough room for a family of four.

The bottom line: If you want the newest S5 with the strongest mix of performance, utility, and cabin tech, the 2025 is the one to target. If you’re more price-sensitive, you can shop the market carefully and focus on the lower end of the range, but the 2025’s redesign and tech make it the primary choice here.
