Used 2025 Audi S5 for Sale near Montana

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 luxury sedan with a more exciting edge. The model scores 9/10 across Form and function and Technology.

The 2025 Audi S5 is described as a performance-tuned German sports sedan with a stealthy design, thrilling dynamics, and enough room for a family of four. It also blends performance, comfort, utility, and modern tech in a way that makes it feel more versatile than a typical luxury sedan.

The trade-offs are clear: the styling is uninspired, the highway ride can be noisy, and the driver assistance systems are unimpressive. Even so, if you want a car that feels most rewarding on a favorite back road while still working as an everyday luxury car, the S5 fits that brief well.

Good and great deals account for 35.5% of listings, which gives you a decent amount of market choice.

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 well-rounded, modern luxury performance car, and the expert review emphasizes its strong overall quality, refinement, and technological sophistication. Its powertrain is described as a deeply satisfying powerplant with seemingly limitless power, and the car’s everyday behavior is competent even if it feels most alive when driven hard.

Audi also includes a generous trial subscription to connected services, which helps the ownership experience feel more complete early on. For used buyers, the main long-term risk is that the car’s high-performance character, weight, and advanced tech can make upkeep and repair costs more important to watch closely over time.

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

Accident-free inventory is excellent at 97.8% — clean inventory, standard diligence applies.

You should still run a history report and prioritize a pre-purchase inspection, especially if you’re considering a higher-mileage example or one with optional equipment. Focus on overall condition, tire and brake wear, and whether the cabin and electronics behave as expected, since this car leans heavily on its tech and performance hardware.

Key things to evaluate:

• Trim level: Premium, Premium Plus, and Prestige are the trims to compare. The base trim already brings a strong equipment list, while the higher trims add more convenience and luxury features.
• 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 quick, but the fuel economy is only average for the class.
• Safety package: Premium models include 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, a lane-centering assist system, a surround-view camera system, and Park Assist Plus.
• Infotainment: The cabin uses an 11.9-inch Audi Virtual Cockpit display and a 14.5-inch MMI touchscreen. Prestige adds a 10.9-inch passenger touchscreen. Wireless smartphone integration is not mentioned, but the Audi Digital Assistant is highlighted as responsive, and Audi Connect Nav is included for three years.
• Fuel efficiency: The official EPA combined rating is 22 mpg, and the review notes an observed average of 21.8 mpg during testing.

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 core S5 experience without paying for extras. It already gives you the V6 powertrain, standard all-wheel drive, and a strong safety suite, so it covers the essentials well.
• Premium Plus: This is the best-value trim for many shoppers because it adds useful upgrades like the head-up display, the 20-speaker Bang & Olufsen sound system, Adaptive Cruise Assist, the surround-view camera system, and Park Assist Plus.
• Prestige: Choose this if you want the most upscale version of the S5, 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 specifically want the extra luxury and chassis hardware.

The safety package is strongest on Premium Plus and Prestige, since those trims add Adaptive Cruise Assist, the surround-view camera system, and Park Assist Plus.

Is the 2025 Audi S5 safe?

The 2025 Audi S5 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.

Premium Plus and Prestige add Adaptive Cruise Assist, which brings lane-centering assist, along with a surround-view camera system and Park Assist Plus. The review also notes that the lane-assist system can be overly aggressive and that the car experienced an unexplainable braking event during testing, so you should not assume the driver-assistance tech will feel polished in everyday use.

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:

• 35.5% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 97.8% — clean inventory, standard diligence applies.

• Updated and mostly upgraded, the redesigned S5 brings a stealthy design, thrilling dynamics, and impressive Audi Digital Stage technology.

The bottom line: If you want the newest S5 with the strongest mix of performance, tech, and everyday usability, the 2025 is the one to target. If you are more price-sensitive, you can shop carefully and focus on the trims that give you the features you actually want, especially if you do not need the top-end luxury extras.
