The new 2017 Mercedes-Benz E-Class hits the streets with the promise of improved fuel economy, cutting-edge safety gear and enough comfort technology to keep it highly competitive in the luxury sedan segment. The base E300 is powered by a 241-hp, 2.0-liter turbo four-cylinder that is linked to a nine-speed automatic. Diesel and high-performance AMG variants will come later. An optional driver-selected suspension allows both sport and comfort settings. Inside, the dash is dominated by a relatively massive high-resolution screen similar to the one in the S-Class. The new E-Class also gets what the company is calling touch-sensitive control buttons on the steering wheel. New safety highlights include a “Car-to-X communication” system, which uses your mobile phone to exchange information with other vehicles further down the road.
