Eric's Autos: 2018 Mercedes E400 Cabriolet
All-wheel drive is available. The standard engine is a twin-turbo V-6.
Though it's a midrange E-Class, many of the high-end features formerly exclusive to the S-Class are now standard or optional.
What's Not So Good
Gas mileage and range drop a lot when you opt for AWD.
Price does not include a teenager to help you sort through all the touch/swipe/tap technology.
Under the Hood
The E400 cabrio (and coupe) comes standard with the twin-turbo 3.0-liter V-6 that's optional in the E-Class sedan and E-Class wagon. So instead of 241 horsepower and 273 foot-pounds of torque, you get 329 horsepower at 5,250 rpm and a mighty 354 foot-pounds of torque at just 1,600 rpm.
The power feeds through a nine-speed speed automatic transmission with driver-selectable modes (these also include chassis settings that can be configured individually to suit), and you can go all-wheel drive (4Matic) or rear-wheel drive.
Mileage with rear-wheel drive is 20 mpg city and 25 mpg highway. But with 4Matic AWD, the highway number drops by 5 mpg to just 20.
