2014 Mercedes-Benz E-Class: 21 mpg city, 31 highway (E350 Sedan); 21/29 (E350 4Matic Sedan); 19/26 (E350 4Matic Wagon); 20/28 mpg (E350 4Matic Coupe); 20/29 (E350 Coupe); 20/28 (E350 Cabriolet)
2014 Mercedes-Benz E-Class: 24 mpg city, 30 highway (E400 Hybrid); E550 4Matic (17/26 mpg); E550 Cabriolet (17/26); E550 Coupe (18/26); E63 AMG (16/24); E63 AMG 4Matic (16/23); E63 AMG S 4Matic Wagon (15/21 mpg)
Stop/start is here too, and it's not the fig leaf you'd think, even if it starts the E63 AMG in second gear when the tranny's in comfort/economy mode and thwaps the drivetrain to life with a mini-riding crop.
The Mercedes-Benz E-Class is one of the few vehicles that covers all of the most commonly available engine types. It's powered by gas, by a combination of gas and electricity, and by diesel, with the latter two drivetrain options delivering the top estimated fuel economy.
Mileage figures are close to those of last year's model--except in the case of the new turbodiesel four, which replaces the larger-displacement turbodiesel V-6. EPA fuel economy figures weren't yet out for that engine at our latest update.
The E350 sedan rates up to 21 mpg city, 31 highway. Stepping through the all-wheel-drive versions of the four-door and wagon, and the two-door coupe brought mileage down to 20/28 mpg, a bit lower for some of the other body styles.
The high-performance E63 AMG models were rated as low as 15 mpg city, 23 mpg highway--or 15/21 for the new E63 AMG Wagon.
Given that last year's E350 BlueTEC earned 22/32-mpg fuel economy numbers, it's a good bet the new turbo four-cylinder diesel in the E250 Bluetec will hit 35 mpg on the highway cycle. In an early drive, we managed to see 38 mpg, including some aggressive, non-mindful driving; so we expect a real-world 40 mpg on the highway to be quite easily achievable.
Both a diesel and a hybrid edition give a green lift to a lineup heavy with near-600-horsepower V-8s.
