The GLE 500 e 4MATIC burns 3.7–3.3 liters of fuel for every 100 km (63.5 to 71.2 mpge), equating to CO2 emissions of 84–78 g/km; electric power consumption is 16.7 kWh per 100 km. All-electric range is up to 30 km (18.6 miles), and all-electric top speed is 130 km/h (81 mph)—corresponding to the recommended speed on German autobahns.
The plug-in hybrid powertrain comprises a BlueDIRECT V6 direct-injection gasoline engine with 245 kW (333 hp); a hybrid module with 85 kW (116 hp) of electric power integrated into the 7G-TRONIC PLUS seven-speed automatic transmission; and an 8.7 kWh Li-ion battery pack.
Peak system torque is 650 N·m (479 lb-ft), while the system’s overall output is 325 kW (442 hp). This enables the full-size SUV to accelerate from 0 to 100 km/h in 5.3 seconds and reach a top speed of 245 km/h (152 mph).
Compared with the conventional GLE 500 4MATIC, external charging with the European electricity mix can cut CO2 emissions by around 37% (31.9 tonnes); a greater reduction of 58% (50.3 tonnes) is possible if renewable electricity is used.
When the individual life cycle phases are considered in detail, the energy required to produce the plug-in hybrid vehicle is initially higher than for its conventional cousin: 234 GJ versus 190 GJ, or about 23% higher. In the operating phase, however, energy requirements are reduced significantly due to the vehicle’s efficiency.
The best result is achieved when renewable energy is used to charge the batteries. Over the entire life cycle, this can translate into primary energy savings of 42%. This is equivalent to the energy content of around 4,385 gallons of gasoline.
