Specs side by side
What owners say
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.
- **C8 Generation (2.9L Twin-Turbo V6 & 48V System):** * Alternator/48V mild-hybrid system battery issues: Subject of a recall. Frequency: recurrent. * Leaky turbo seals: Mentioned as a known issue. Frequency: isolated.
- **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.
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.

It has more power on its best-equipped version than the Audi S7, based on the data above. If efficiency matters more to you than outright power, the Audi S7 is worth a closer look instead.
