The 2020 Mercedes-Benz GLE is currently available with two engines options. The GLE 350 uses a 2.0-liter turbo four which produces 255 horsepower and 273 lb-ft going out to rear-wheel-drive or 4Matic all-wheel-drive, while the GLE 450 uses a 3.0-liter turbo inline-six with a 48-volt EQ Boost producing 362 hp and 369 lb-ft. Mercedes will likely introduce more variants of the GLE, including a high-powered GLE 63 AMG version, but the company has yet to confirm anything.

We know the GLE 63 will produce around 600 hp, which is a significant step up from the 362 hp rating of the GLE 450 model. Thanks to a recent visit to a local Mercedes dealership, CarBuzz now has exclusive information on how Mercedes plans to bridge the gap between the mid-level GLE 450 and the high-performance GLE 63.

We initially thought Mercedes would introduce a GLE 53 AMG, using the same 429-hp output version of the 3.0-liter inline-six with mild hybrid assist as found in the E-Class, CLS, and AMG GT Four-Door. While this still remains a possibility, it appears Mercedes plans to give the GLE an engine from the recently-revealed GLS.

The 2020 GLS debuted at the 2019 New York Auto Show with a trim level called the GLS 580. Powering the GLS 580 is a 4.0-liter twin-turbo V8 mated to a 48-volt EQ Boost mild hybrid system. The EQ Boost system provides an additional 21 hp and 184 lb-ft of torque, for a total power output of 483 hp and 516 lb-ft.

While we were at the dealership our salesperson showed us an order sheet for the GLE, revealing an upcoming GLE 580 model. Considering the larger GLS 450 produces identical power and torque as the GLE 450, the GLE 580 will likely have the same output as the GLS 580. The 4.0-liter V8 engine is a detuned version of the one found in AMG cars, so we wouldn't be surprised if future AMG models used a 48-volt mild hybrid system as well. The order form didn't reveal pricing or availability but we wouldn't be surprised if Mercedes announced the GLE 580 before the end of 2019.
