Based on the redesigned midsized GLE, the GLE Coupe is Mercedes-Benz's answer to the coupelike BMW X6 SUV. The AMG 53 has a powerful 429-hp, 3.0-liter turbo six-cylinder engine with EQ Boost. The uplevel AMG 63 S has a 603-hp, 4.0-liter V8 turbo engine. Both engines are mated to a nine-speed automatic transmission. The new GLE that we tested is very quiet and impeccably finished inside, and has excellent seats. It comes with the Mercedes new infotainment system that has one large screen that contains the instrument panel and center screen. Audio, phone, navigation, and some comfort settings can be changed through the touchscreen, touchpad, or steering-wheel, touch-sensitive controls. We found the system extremely distracting to use, even with the ability to use voice commands. Forward collision warning and automatic emergency braking are standard.
