The redesigned E-Class delivers nimbler handling and better fuel economy than the previous generation. On the other hand, it dials back on ride comfort, interior room, and user-friendliness. The E300's 241-hp, 2.0-liter turbo four-cylinder is linked to a nine-speed automatic. This combination works well, but it won't set your heart on fire. Then again, we got a commendable 24 mpg overall. The car is quiet and handles with newfound agility. Though the ride is comfortable, it lost some plushness. Inside, the dash features high-resolution displays, but the controls have grown more complicated. Even adjusting the seat's lumbar support is a multistep process done through the central controller and screen. New technology gives the E-Class the ability to follow the road and steer itself temporarily as a driver-assist feature.
