2019 Mercedes-AMG CLS53 packs beauty, brains and brawn

The Mercedes-AMG CLS53 comes with a 3.0-liter turbocharged inline-six that produces 429 horsepower and 384 pound-feet of torque.

This car has an EQ Boost system, with a 48-volt battery and starter-alternator, which offers as much as 21 hp and 184 pound-feet of torque to aid with initial acceleration.

The CLS53 comes with 4Matic all-wheel drive standard.

Mercedes also sells a non-AMG version -- CLS450 -- with rear- or all-wheel drive.

The CLS63 will sprint to 60 miles per hour in 4.4 seconds.

The 3.0-liter I6 engine mates to a nine-speed automatic transmission.

The AMG CLS53 gets a standard air suspension.

Inside, there are two 12.3-inch display screens and 64 different ambient lighting colors.

The CLS was -- arguably -- the original "four-door coupe," and it looks absolutely stunning in its third generation.
