Specs side by side
What owners say
RS7
Overall
Owner sentiment is generally positive, with the RS7 praised as a fast, comfortable, and capable grand tourer that blends performance with daily usability. The twin-turbo 4.0L V8 engine is frequently highlighted for its immense power and linear delivery, providing a "blazing fast" and "spectacularly fast" experience. The car is consistently described as comfortable for long-distance cruising, with a refined interior and a balance of luxury and sportiness.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. Discussions reference various model years and trims (e.g., 2016 RS7 Performance, 2024 RS7 Performance with increased power) without a clear preference emerging from the community feedback.
Known issues
- High Cost of Maintenance and Repairs: Very expensive routine maintenance, brake jobs (cited at ~$4,000 USD), and part replacements. Owners note a significant "RS Tax" on model-specific components. Frequency: very frequent.
- Turbo Oil Screen/Strainer Failure: A major, widespread issue primarily affecting the C7/C7.5 generation's 4.0T V8. Faulty screens can clog, leading to turbocharger failure and catastrophic engine damage.
- Suspension Comfort Degradation: Owners report the adaptive suspension in Comfort mode losing its plush, "gliding" quality over time, becoming noticeably firmer. Potential causes include worn components or calibration issues.
S7
Overall
Sentiment is divided and heavily dependent on the specific generation and powertrain. The vehicle is universally praised for its styling, which is noted to age exceptionally well, its potent performance, and its refined, high-quality interior. However, significant concerns center on reliability and maintenance costs, with a stark generational divide.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. Data suggests a strong preference for the supercharged 3.0L V6 in the A7 over the turbocharged V8 in the S7 for its perceived reliability and lack of lag, though this is not a direct S7 comparison.
Known issues
- **C7 Generation (4.0L Twin-Turbo V8):** * Turbocharger failure due to defective oil screen/strainer: Catastrophic failure leading to engine damage, subject of a manufacturer recall and reimbursement program. Frequency: very frequent.

- **General (Across Generations):** * High cost of repairs and parts: Extremely high parts costs cited (e.g., a single headlight at $13,000 USD). Frequency: very frequent.
