For the new E-Class E300 sedan and E400 wagon, standard feature highlights include LED headlights, automatic wipers, heated power-folding mirrors, a sunroof, selectable drive modes, an adaptive suspension, dual-zone automatic climate control, premium synthetic leather upholstery, power-adjustable front seats with driver memory functions, 40/20/40-split folding rear seats, a power liftgate (wagon), a 12.3-inch display, Mercedes' COMAND infotainment system with a touchpad controller, voice controls, a navigation system, Bluetooth, Apple CarPlay and Android Auto, HD radio and two USB ports. Sport and Luxury versions are available for both. The Sport has bigger wheels, a sport-tuned suspension and brakes, and special styling details.

If want more pizzazz, the AMG E43 sedan is available. It comes with a more powerful engine, an AMG sport-tuned suspension and braking, 19-inch wheels, AMG-specific interior and exterior pieces, and leather upholstery.

For the most part, the above variants share optional Premium Package designations and content. The Premium 1 package adds a rearview camera, an automated parallel and perpendicular parking system, a wireless phone charger, satellite radio, keyless entry, a power trunklid (sedan) with hands-free activation, blind-spot monitoring with rear cross-traffic alert, heated front seats and a 14-speaker Burmester surround-sound system. The Premium 2 package includes all of the Premium 1 package, along with adaptive headlights with automatic high-beams, active multicontour front seats with massage functions, a perfumed air freshener system and a power rear sunshade (sedan). The Premium 3 package includes all of the above plus a surround-view camera system, adaptive cruise control with steering and lane-change assist, a speed-limit sign reader, front-collision and cross-traffic warnings and mitigation, evasive steering assist, active blind-spot assistance, a head-up display, and Pre-Safe side and rear impact preparation.

Other notable options include the Warmth and Comfort package (rapid heating for front seats, heated front armrests, upper door panels and steering wheel), the Rear Safety package (rear side airbags and seat-belt airbags), an adaptive air-ride suspension, a panoramic sunroof, ventilated front seats, an upgraded gauge cluster display, additional sound and solar insulation, and a couple of premium Burmester sound systems. Numerous upholstery and trim options are also available.

The four-passenger E400 and E550 coupe and convertible are largely unchanged from the previous year and come with most of the sedan's features, albeit without the latest style and technology. Standard feature highlights include 18-inch wheels, a panoramic sunroof, adaptive suspension and leather upholstery. The COMAND touchpad controller is not available, and items such as navigation and smartphone integration are optional. The convertible models receive a power-folding fabric top, Mercedes' Aircap wind deflector and a rear center pass-through. The Airscarf neck-warmer is available as an option.

The only available engine for the 2017 Mercedes-Benz E300 sedan is a turbocharged 2.0-liter four-cylinder that produces 241 horsepower and 273 pound-feet of torque. A nine-speed automatic transmission sends power to the rear wheels on standard models, while 4Matic models feature all-wheel drive.

In Edmunds testing, an E300 sedan accelerated to 60 mph in 7.0 seconds, which is slightly slower than average among competing midsize luxury sedans. The EPA estimates fuel economy at 25 mpg combined (22 city/30 highway) for the rear-drive model and 24 mpg combined (22 city/29 highway) for the 4Matic. These figures also trail the competition by a few mpg.

The E400 wagon and AMG E43 sedan both have a turbocharged V6 engine and standard all-wheel drive. In the wagon, the engine produces 329 hp and 354 lb-ft of torque. The E43 upgrades to 396 hp and 384 lb-ft of torque. As with the four-cylinder, gear changing is handled by a nine-speed automatic.

The E400 coupe and convertible are powered by the wagon's 3.0-liter V6 engine (329 hp and 354 lb-ft) but have a  seven-speed automatic transmission that sends power to the rear wheels. 4Matic is available as an option for the coupe only.

Finally, the E550 coupe and convertible get a turbocharged 4.7-liter V8 that makes 402 hp and 443 lb-ft of torque. Mercedes estimates it will reach 60 mph in 4.9 seconds.
