Gas mileage: 22/30; 25
The EPA-estimated 25 combined mpg is impressive for a large, long car. It's costly for a hybrid but the best of the full-size luxury sedans, beating the Porsche Panamera S Hybrid, Mercedes-Benz S400 Hybrid and preposterous Lexus LS 600h. However, the gas-only BMW 740 scores better with an estimated 22 mpg combined for $74,495. The Mercedes S400 is the only hybrid luxury car that beats its gas-only version, by a slim margin.
