Power for the Coupe comes from a hand-built 5.5-liter V8 engine that uses two beefy turbochargers to make 577 horsepower between 5,250 and 5,750 rpm and 561 lb-ft. of torque from 1,750 all the way up to 5,250 rpm. Bolted to a seven-speed automatic transmission, the eight-cylinder sends the GLE63 from zero to 60 mph in 4.2 seconds a statistic that's all the more impressive when the crossover's 5,180-pound weight is factored in.
Fuel economy is rated at 14 mpg in the city and 18 mpg on the highway thanks in part to a standard start/stop system.
Air suspension (called Airmatic in Mercedes-speak) comes standard. The crossover-coupe also boasts an AMG Dynamic Select function that lets the driver pick from five driving modes: Individual, Slippery, Comfort, Sport and Sport +. Selected using a rotary knob located on the center console, the modes change a variety of parameters including the suspension firmness, the steering response, the throttle response, how long the transmission holds each gear, and even the sound emitted by the exhaust system.
Charting the Changes
Outside, the GLE63 S Coupe stands out from the GLE450 AMG thanks to a full body kit that adds larger front air inlets, a front splitter and flared wheel arches. It rides on 22-inch alloy wheels.
The upgrades continue in the cockpit with a three-spoke flat-bottomed steering wheel, aluminum shift paddles, an AMG-specific instrument cluster and anthracite poplar wood trim.
With a high seating position and a tall dashboard, the connection between the GLE63 Coupe and the standard GLE63 is immediately evident as soon as you step in the cockpit. The instrument cluster is made up of four analog gauges and a configurable color screen in the middle.
A larger, high-definition color screen sticks out from the top of the dashboard, and an innovative, smartphone-like touch pad located on the center console lets the passengers control the COMAND infotainment system with simple finger gestures. Occupants can also use the touch pad to enter an address in the navigation system (if equipped) or to add a contact to the phone book. Alternatively, COMAND can be navigated via a controller knob located under the touch pad, voice commands or buttons on the center stack.
Trunk space checks in at just 12.6 cubic feet with five occupants on board. Folding down the 60/40 rear bench yields 60.7 cubes.
