With the new Performance models based on the GLE, Mercedes-AMG is continuing a precisely 20 year-old tradition: in 1999 the ML55 as the progenitor based on the then M-Class was the top model in the range with its 255 kW (347 hp) V8 engine. The same applies to its current successor in the guise of the Mercedes-AMG GLE63 4MATIC+. The top-of-the-line performer of the model series is naturally taking to the starting line with state-of-the-art engine technology: the AMG 4.0-litre V8 biturbo engine generating 420 kW (571 hp) in the GLE model series and 450 kW (612 hp) in the S version is combined for the first time with the EQ Boost starter-alternator. This is accompanied by an additional electric output of 16 kW (22 hp), a 48-volt on-board electrical system, cylinder shut-off and petrol particulate filter for optimum efficiency. Furthermore, the fully variable all-wheel drive, the air suspension with adaptive damping adjustment and active roll stabilisation and the extremely fast-shifting TCT 9G transmission further move the limits of vehicle dynamics upwards. On top of this there are the advantages of a luxury SUV: good all-round visibility, plenty of space for passengers and luggage, high-quality materials and the brand's very latest driving assistance, infotainment and connectivity functions. Even more versatility is provided by the improved off-road capabilities with the two additional drive programs "Trail" and "Sand", as well as the variable vehicle level. This is where extreme sportiness, first-class off-road characteristics and absolute day-to-day suitability come together.
