The exterior dimensions of the 2015 Mercedes E5350 are essentially the same as the dimensions of the other E-Class vehicles of the same model year and body style. However, there are significant differences in weight between other E-Class cars and even other E350 vehicles, due to engine and drivetrain options.
The 2015 Mercedes-Benz E-Class line of cars is available in sedan, coupe and wagon body styles, with the E350 version available in sedan and wagon versions. The E350 designation indicates that the car is powered by the naturally aspirated version of the Mercedes-Benz 3.5-liter V6 engine. As all the E-Class cars are based on the same underlying platform, the external dimensions of a particular body style remain essentially the same regardless of trim level. For example, the E350 sedan has the same length, width, height and wheelbase as the E63 AMG powered by a 5.5-liter twin-turbo V8 engine.
However, different trim levels and body styles among the E-Class vehicles can differ significantly in weight. E-Class coupes tend to be lighter than sedans, while wagons tend to be slightly heavier than either other option. One of the most significant factors affecting the weight of an E-Class car is the presence of a 4MATIC all-wheel drive system. For example, an E350 Sport sedan with rear-wheel drive is nearly 200 pounds lighter than one with all-wheel drive.
