The Porsche Panamera is not a 7-seat vehicle. Most Panamera models are designed as four-seat sports cars, but some models, such as the Panamera Sport Turismo, offer a 4+1 seating concept. This means they can accommodate five passengers, but the fifth seat is not a full-size individual seat and is more suited for short or medium distance trips rather than long journeys.

A well-maintained Porsche Panamera can last around 150,000 miles, which is a typical lifespan for a luxury vehicle of this caliber. Proper care, including regular maintenance, avoiding bad driving habits, and using quality parts, can significantly extend the vehicle's life. High mileage for a Panamera is generally considered to be above 100,000 miles, at which point serious repairs can become costly. However, some owners have reported their Panameras lasting up to 200,000 miles or more with diligent maintenance. Models from 2014 onwards are generally more reliable, having ironed out many of the issues present in earlier years such as engine and transmission problems, coolant leaks, and electronic malfunctions[5).

The Porsche Panamera's fuel efficiency varies significantly depending on the model and engine configuration. For the traditional gas-powered models, the 2023 Porsche Panamera typically achieves 18 mpg city, 24 mpg highway, and 20 mpg combined. However, the hybrid models offer substantially better fuel economy, with the 2022 Porsche Panamera 4S E-Hybrid and Turbo S E-Hybrid achieving up to 50 MPGe and 48 MPGe combined, respectively. This makes the hybrid configurations of the Panamera notably more fuel-efficient compared to the standard gas-powered versions.
