The Maybach 57 was tied as the 7th worst vehicle for the environment. The American Council for an Energy-Efficient Economy gave the cruiser 20 out of 100 points. By comparison the ACEEE's most energy efficient vehicle, the Mitsubishi i-MIEV, received 58 out of 100 points. 'Motoramic' says the 12-cylinder posh vehicle gets 16/10 mpg highway/city.
