Bentley Continental Flying Spur
The Bentley Continental Flying Spur is a luxury powerhouse, equipped with a W12 engine that delivers 626 horsepower. While its performance is unmatched, it comes at the cost of fuel efficiency, averaging around 12-19 MPG. This makes it a gas-guzzler despite its smooth ride and opulent features, such as a lavish interior and top-tier craftsmanship.
Maserati Quattroporte
With a Ferrari-sourced 3.8-liter twin-turbo V8, the Maserati Quattroporte delivers exhilarating performance. However, its fuel efficiency is a weak point, with an average of 13-20 MPG.

Rolls-Royce Phantom
Known for ultimate luxury, the Rolls-Royce Phantom features a massive 6.75-liter V12 engine, delivering unparalleled comfort and power. However, with an average of 12 MPG in the city, it’s a serious fuel guzzler. Despite its poor efficiency, the Phantom’s regal presence and hand-crafted interiors justify its spot among iconic luxury sedans.
Mercedes-Benz S65 AMG
Powered by a twin-turbo 6.0-liter V12 engine, the Mercedes-Benz S65 AMG offers blistering performance with 621 horsepower. However, its 13-22 MPG rating underscores its fuel-hungry nature. The S65 AMG is for those who prioritize luxury and speed over fuel economy, making it an inefficient but thrilling ride.

The hybrid system delivers strong performance, but this flagship sedan’s fuel economy lags behind newer hybrids, making it an inefficient choice in the luxury segment.
Jaguar XJ Supercharged
With a supercharged 5.0-liter V8, the Jaguar XJ delivers 470 horsepower, but its fuel efficiency is a letdown, averaging 15-23 MPG. While the XJ impresses with performance and style, its gas mileage is far from competitive, making it a fuel-intensive luxury sedan.
Audi S8
The Audi S8’s twin-turbocharged 4.0-liter V8 engine produces 563 horsepower, but it comes with a penalty in fuel consumption, averaging around 14-22 MPG. The S8 delivers high performance and cutting-edge technology, but its thirst for fuel makes it a costly option at the pump.

Porsche Panamera Turbo
The Porsche Panamera Turbo’s 4.0-liter twin-turbo V8 provides 620 horsepower, but its fuel efficiency is a concern, averaging around 15-22 MPG. While it offers thrilling performance and luxury, the Panamera Turbo’s fuel consumption makes it a high-cost vehicle to maintain.

Lincoln Continental 3.0T AWD
The Lincoln Continental 3.0T AWD is equipped with a twin-turbo 3.0-liter V6 that delivers 400 horsepower but struggles with fuel efficiency, averaging 17-25 MPG. While it offers premium comfort and classic styling, the fuel economy is subpar for a modern luxury sedan.
Maserati Ghibli
The Maserati Ghibli offers exhilarating performance with its 3.0-liter twin-turbo V6 engine, but with an average of 16-24 MPG, it’s not known for fuel efficiency. The Ghibli’s blend of Italian styling and sporty dynamics comes at the cost of higher fuel consumption.
