The GLE 450e is new for 2024. It uses the same engine from the gas-only 350, namely a 2.0-liter turbocharged inline-four, but augmented with a plug-in hybrid system for total outputs of 381 hp and 479 lb-ft. AWD is standard and a nine-speed automatic rows the gears. The PHEV has a claimed 48-mile all-electric range.
Like the rest of the range, the GLE 450e gets dual 12.3-inch displays, dual-zone climate control, heated front seats with power adjustment, a power sunroof, and MBUX infotainment as standard. This includes wireless Apple CarPlay and Android Auto, navigation, and an eight-speaker sound system. It rolls on 19-inch wheels and has a power tilt-and-slide sunroof.
