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.
Panamera
Overall
Sentiment is deeply divided and heavily dependent on model year, powertrain, and ownership expectations. Long-term owners of V8-powered models, particularly the GTS and Turbo variants from the second generation (2017+), frequently praise them as among the best daily drivers they have ever owned, citing a blend of exceptional performance, practicality, safety, and surprising reliability with proper maintenance. However, significant and severe criticism is directed at the E-Hybrid models, especially first-generation examples, which are described as profoundly unreliable with catastrophic electrical failures, frequent breakdowns, and extremely short hybrid battery life (reportedly 3-5 years).
Best version to buy
Second-generation (2017+) V8 models, specifically the GTS and Turbo variants. The GTS is highlighted for its intoxicating engine character and as a sweet spot in the lineup.
Known issues
- ⚠Catastrophic E-Hybrid system failures: including complete electrical system failures, stranding owners, requiring frequent towing, and very short hybrid battery life (3-5 years). Frequency: very frequent for first-generation hybrids.
- ⚠Air suspension failures: compressor and component failures, typically occurring after 50,000-70,000 miles, with repairs costing several thousand dollars. Frequency: very frequent.
- ⚠High maintenance and repair costs: extremely expensive parts (e.g., tyres, brakes), dealer service, and repairs; described as "running a £70,000 car" even when purchased used. Frequency: very frequent.
