Used 2025 Audi S5 for Sale nearSaint Louis, MO

Is the 2025 Audi S5 a good car?

Yes — the 5/5 user rating and 7.00/10 expert rating point to a car that lands well with shoppers who want a performance-focused daily driver. The 2025 Audi S5 is described as a redesigned, multi-talented sportback with performance, comfort, utility, and the latest technology, and it is aimed at buyers who want something more engaging than a typical luxury sedan.

The model scores 9/10 across Form and function and Technology.

That said, the trade-offs are real: the styling is uninspired, the highway ride can be noisy, and the driver-assistance tech is not especially impressive. Even so, the S5’s stealthy design, thrilling dynamics, and practical cargo space make it a strong fit if you want a sporty car that still works as an everyday four-door.

Good and great deals account for 28.7% of listings, so you have 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 sportback with strong performance, and its overall package suggests a car built to satisfy drivers who care about both pace and everyday usability.

The performance side also reads well: the turbocharged V6 is described as a deeply satisfying powerplant with seemingly limitless power, and the car’s chassis tuning, steering, brakes, and adaptive damping all contribute to a polished driving experience. On the ownership side, Audi includes a generous trial subscription to connected services, which adds some early-life convenience.

The main long-term ownership risk for used buyers is that the car’s advanced tech and driver-assistance systems may be more frustrating than reassuring over time.

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

Accident-free inventory is excellent at 96.3% — clean inventory, standard diligence applies.

You should still run a vehicle history report, verify service records, and prioritize a thorough pre-purchase inspection. Pay close attention to cabin condition, wheel and brake wear, and whether the tech and driver-assistance features operate as expected on a test drive.

Key things to evaluate:

• Trim level: Premium, Premium Plus, and Prestige each add meaningful equipment, with the base trim already getting a wide range of driver-assistance features. The higher trims bring more luxury and convenience, while the Prestige adds the most upscale tech and comfort touches.
• 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 transmission and standard Quattro all-wheel drive. It is tuned for strong acceleration and enthusiastic driving, but the fuel-economy trade-off is part of the package.
• Safety package: The standard suite 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. Adaptive Cruise Assist, with lane-centering, plus a surround-view camera system and Park Assist Plus, are reserved for higher trims.
• Infotainment: The cabin features an 11.9-inch digital instrument display and a 14.5-inch MMI touchscreen, with a 10.9-inch passenger screen on Prestige. Wireless smartphone integration is not stated, but the system does include Audi Digital Assistant and over-the-air capability is not stated.
• Fuel efficiency: The official EPA fuel economy rating is 22 mpg in combined city and highway driving, 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 value play if you want the S5’s core performance and a long list of standard safety features without paying for extras you may not need. It gives you the essential S5 experience and is the trim to start with if you care most about driving enjoyment.
• Premium Plus: This is the best-value trim for many shoppers because it adds a head-up display and a 20-speaker Bang & Olufsen sound system with 3D audio. If you want a more premium daily driver without going all the way to the top trim, this is the sweet spot.
• Prestige: Choose this if you want the most upscale version, including the passenger touchscreen and the adaptive-damping sport suspension. It is the most feature-rich trim, but it makes the most sense if you will actually use the extra luxury and tech.

The safety package is strongest on Premium Plus and Prestige, which add Adaptive Cruise Assist, a surround-view camera system, and Park Assist Plus.

Is the 2025 Audi S5 safe?

The 2025 Audi S5 does not have a crash-test rating cited here, but it does come with a broad standard driver-assistance suite. It earns a 4/10 safety score from our experts.

Every 2025 Audi S5 Premium boasts a comprehensive list of driver-assistance systems, including 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.

Choose Premium Plus or Prestige if you want Adaptive Cruise Assist, which adds lane-centering, plus a surround-view camera system and Park Assist Plus. The main caveat is that the lane-assist behavior can be intrusive and inconsistent, and the system does not offer hands-free traffic-jam or highway capability.

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:

• 28.7% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 96.3% — clean inventory, standard diligence applies.
• Owners rate it 5/5 — a strong satisfaction signal.
• The redesigned S5 emphasizes thrilling dynamics, practical cargo space, and the new Audi Digital Stage tech.

Consider the 2026 if:

• Audi adds an all-new MMI system with AI voice controls and complimentary scheduled maintenance.

The bottom line: The 2025 is the better pick if you want the redesigned S5 now and value its performance-first character. If you are more focused on ownership perks and updated tech, the 2026 is worth a look, especially if you are willing to wait or pay a bit more for the newer setup.
