The the GLE line is the replacement for the old ML-Class SUV, under Mercedes’ increasingly (convoluted) diverse naming scheme. “G” indicates that it’s part of the SUV family, under the grandaddy G-Wagon, with the rest of the nomenclature positioning it somewhere on the Mercedes-AMG family branch. The GLE 450 Coupé, with a V6 biturbo engine good for 367 horsepower, is the entry point to the line. The Mercedes-AMG GLE 63 S Coupé is the fastest with a V8 biturbo and 585 horsepower. The bigger brother to the GLE 63 S Coupé is the behemoth Mercedes-AMG GLE 63 S. Same engine as the little brother, but more heft. There’s variants throughout, but for our driving purposes, we went (naturally) for the fastest and biggest.
An SUV with the AMG treatment is an interesting beast. With the 585 horsepower 560 lb-ft 5.5-liter twin-turbo V8, you find yourself constantly stabbing at the throttle on the straights out of pure amusement, but pushing it through the turns mainly out of curiosity. Will the ship hold? It will. Mercedes makes a fantastic V8, and even after slapping two turbos on the engine, it still keeps an entirely raucous soundtrack (at any speed). And, to leverage that power best, AMG gives the high horsepower lowered, track-tuned suspension. I took the AMG 63 S up in the German Alps on the way to Kitzbuhel, Austria, and took tarmac turns much faster than common sense would dictate. This is a tall and large vehicle, with SUV ancestry. But, the car tells me to stay on the gas and power through the sweeping turns, the twin-turbo V8 talking me out of any doubts. The SUV doesn’t wallow or lean, it stays relatively flat and planted. It doesn’t make sense. The car works so well. And, the GLE 63 S Coupé’s 0-to-62 time of 4.2 seconds is plenty fast enough to justify weekend time on the back straight. But, while glorious in Kitzbuhel, the question is, who exactly is doing this in the real world?
