Engine and Transmission Rating:
Under the E400 coupe and cabriolet’s rippled hood is a stable of 329 twin-turbocharged ponies that easily shuttles these two-door sculptures down the road at more than suitable velocities. The V-6 engine emits a low rumble as it goes about its business, but it never sounds undignified, and at no time does it send unwanted vibrations into the cabin.
The rivals selected for this comparison are smaller because the E-class coupe and cabriolet have no direct competition in the mid-size segment. Of this group, the Audi S5 and the BMW 440i coupes are the quickest, but the Benz holds its own and never feels slow. The E400’s standard nine-speed automatic transmission changes gears seamlessly in Comfort mode, but shifts get sharper and more aggressive in Sport and Sport+, the latter of which doesn’t align with the relaxed nature of the rest of the car. All E-class two-doors are offered with standard rear-wheel drive. All-wheel drive is a $2500 option-cars with this feature wear a 4Matic badge on their trunklids.
Test Results: Acceleration
Manual Shifting Capability
For those who are easily annoyed by automatic stop/start systems, the E400’s is one of the least obtrusive we’ve tested, powering off and on at stoplights with little disturbance to the cabin.
