Mercedes has rounded out its AMG 53-series lineup with the announcement of the 2019 AMG E 53 sedan. Like the CLS sedan and E coupe and cabriolet models unveiled in Detroit earlier this year, the sedan features a 3.0-liter inline-six with conventional and electric turbocharging, 48V electrical system and Mercedes' fully-variable 4MATIC+ all-wheel-drive.

From the outside, the AMG E 53 sedan is marked by a redesigned twin-blade radiator grille, chrome exhaust pipes and rear diffuser combo, along with optional 20-inch 5-spoke AMG alloy wheels.

Hidden underneath the sedan's power-bulge bonnet is a 3.0-liter inline-six with exhaust gas as well as EQ Boost electric turbocharging, which made its first debut on the 2017 S-Class. The engine and exhaust-gas turbo has an output of 429 hp (320 kW) and 384 lb-ft (520 Nm) of torque, while the electric turbo can momentarily provide 21 hp (16 kW) and 184 lb-ft (250 Nm) of additional output for improved low-end response and a 0-60 mph (0-97 km/h) sprint of 4.4 seconds.

Drive is via 9-speed automatic transmission and Mercedes' 4MATIC+ all-wheel-drive, which features active torque distribution between front and rear axles. To help the E 53 sedan slow down from its electronically-limited top speed of 130 mph (210 km/h), Mercedes has fitted massive 14.2'' (361 mm) cross-drilled and vented discs with four-piston calipers on the front, and the same size discs on the back clamped by a single-piston floating caliper.

The 48V electrical system utilizes a starter-generator combo mounted in between the engine and transmission and facilitates mild hybrid functions like energy recovery, coasting and start/stop technology.

The stylish cabin gets AMG performance seats, AMG performance steering wheel, carbon fiber trim, a glass panel that contains the gauges and the large 12.3-inch infotainment screen.

Replacing the E 43 sedan, the AMG E 53 will be available in the US in late-2018. There's no official word on pricing, but expectations are on the high side US$150,000.
