Bentley Flying Spur vs Porsche Panamera: 2025 Comparison
Specs side by side
What owners say
Flying Spur
Overall
Owner sentiment is complex and heavily bifurcated by generation and ownership phase. The vehicle is universally praised for its presence, luxury materials, powerful performance (particularly W12 models), and supreme comfort over long distances. However, a very strong and recurrent theme across all discussions is the extreme cost and complexity of maintenance and repairs, which forms the core of negative sentiment.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. Discussions indicate a split in engine preference.
Known issues
- ⚠Extremely high maintenance and repair costs: includes engine-out services for W12 repairs ($7,000-$15,000 for labor alone), $16,000 infotainment system replacements, $6,000 power steering racks, and $3,000-$5,000 brake jobs requiring speci…
- ⚠Catastrophic depreciation: vehicles lose a majority of their value within a few years, leading to low purchase prices but unchanged ultra-high repair costs. Frequency: very frequent.
- ⚠W12 engine complexity and serviceability: any significant repair requires complete engine removal, leading to prohibitive labor costs. Frequency: recurrent.
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.
