The short answer
Based on available data, the Porsche Panamera comes out ahead of the Maserati Ghibli on fuel economy and power. Check the specs table and owner sentiment below for the full comparison before deciding between the two. Both are covered by real owner reports on CarWizz.
Overall
Sentiment is sharply polarized and heavily dependent on model year and purchase context. The vehicle is widely criticized for its historically poor build quality, especially in early model years (2014-2016), with frequent mentions of cheap interior materials, shared Chrysler parts (e.g., window switches), and perceived lack of refinement for its original $85,000+ MSRP. Reliability concerns and extremely high maintenance/repair costs at dealerships are dominant themes, contributing to a reputation for being a financially perilous ownership proposition.
Best version to buy
2018 and newer models are strongly recommended over earlier versions. Owners and industry observers note that Maserati made significant electronic refinements and smoothed out many quality kinks by the 2017/2018 model years.
Known issues
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.
