Mercedes-Benz reveals facelifted versions of its E-Class coupe and convertible, both planned to see North American delivery by the end of 2020.
The freshened 2-door models will follow the facelifted E-Class sedan and wagon into U.S. showrooms with a number of subtle exterior styling upgrades, including a new-look grille, lightly reshaped LED headlamp assemblies and altered taillamps with new-look lenses.
Inside (below), the E-Class coupe and convertible adopt a lightly reworked interior with features like those already brought to their 4-door siblings. Included is a redesigned steering wheel with capacitive sensor technology, as found in smartphones, for the buttons on each spoke as well as the driver-detection function within the rim.
The new Mercedes-Benz models also feature the latest version of the automaker’s MBUX user interface. It uses two 10.25-in. (26-cm) displays arranged side by side within a single instrument panel as standard – one for the instruments, the other for the infotainment system – in combination with either touch, gesture or speech control. Alternatively, buyers can opt for larger 12.3-in. (31-cm) screens as an option.
In an extension of Mercedes-Benz’s drivetrain electrification program, all newly facelifted gasoline-powered E-Class coupe and convertible models receive 48-volt EQ Boost mild-hybrid properties in combination with a nine-speed, torque-converter-equipped automatic gearbox.
North America will continue with a single standard E450 4Matic model in both lineups. It uses a turbocharged 3.0L inline 6-cyl. and gearbox-mounted electric motor. The combustion engine delivers 362 hp and 369 lb.-ft. (500 Nm) of torque, with the electric motor contributing an additional 21 hp and 184 lb.-ft. (250 Nm) for short periods. Mercedes-Benz claims a 0-62 mph (100 km/h) time of 5.0 seconds for the E450 4Matic coupe and 5.1 seconds for the E450 4Matic convertible. Both are limited to a top speed of 155 mph (250 km/h).
Positioned further upmarket are the E53 4Matic coupe and convertible from AMG’s performance-car division. They use the same turbocharged 3.0L I-6 as the E450 4Matic, but in a higher state of tune with 429 hp and 384 lb.-ft. (521 Nm) of torque.
As with their standard sibling, the E53 4Matic coupe and convertible’s combustion engine is supported by an electric motor with 21 hp and 184 lb.-ft. (249 Nm). So configured, Mercedes-Benz claims respective 0-62 mph times of 4.4 seconds and 4.6 seconds and a 155-mph top speed.
Among the drivetrain developments for European market models is a newly developed diesel 4-cyl. with mild-hybrid properties in new E300d coupe and E300d convertible models.
Known under the internal codename OM654 M, it builds on the earlier OM654 unit with a longer stroke extending its overall capacity from 1,950 cc to 1,993 cc, a new common-rail injection system that operates at pressures up to 2,700 bar (39,160 psi) instead of 2,500 bar (36,259 psi) and two water-cooled variable-vane turbochargers.
Mercedes-Benz claims the OM654 M is the most powerful 4-cyl. diesel yet to appear in a production car. Full details are yet to be revealed, though preliminary information released by the automaker points to a peak power figure of 261 hp for the combustion engine and 20 hp from a gearbox-mounted electric motor.
To put this into perspective, the existing OM654 engine delivers 192 hp.
Further features of the new diesel include a closed NOx storage catalytic converter, a diesel particulate filter and selective catalytic reduction, which uses urea injection to neutralize emissions.
