2020 Mercedes-Benz GLE 580 arrives with V8-electric powertrain

It's the range-topper until AMG launches its version of the SUV.

The rumors were accurate: Mercedes-Benz is expanding the GLE line-up with a range-topping model powered by a V8-electric mild hybrid powertrain. The GLE 580 will reach showrooms in time for the 2020 model year.

Power for the 580 comes from a twin-turbocharged, 4.0-liter V8 engine rated at 483 horsepower and 516 pound-feet of torque. An integrated starter-generator (ISG) harvests the kinetic energy generated while braking to send 21 horsepower and 184 pound-feet of torque through the driveline when a temporary overboost function kicks in. Fed by a 48-volt electrical system, the ISG also powers components like the water pump and the air conditioning compressor.

The eight-cylinder spins the four wheels through an automatic transmission, and Mercedes' 4Matic all-wheel drive system. The company hasn't released performance or fuel economy figures yet.

Visually, the 580 looks a lot like the other variants of the GLE. It's the same story inside, though it's evidently better equipped than cheaper models. It notably comes standard with a 12.3-inch touchscreen for the MB UX infotainment system, and a second 12.3-inch screen that replaces the analog instrument cluster.

Mercedes-Benz will begin shipping the 2020 GLE 580 in late 2019. Pricing starts at $76,800 excluding a $995 destination charge. When it lands, it will join the GLE 350 and GLE 450 models in showrooms, and it will later be joined by an AMG-tuned GLE 63 with at least 600 horsepower on tap.
