With the new Performance models based on the GLE, Mercedes-AMG is continuing a precisely 20 year-old tradition: in 1999 the ML 55 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 GLE 63 4MATIC+ (combined fuel consumption: 11.5-11.4 l/100 km; combined CO2 emissions: 262-261 g/km)[1]. 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.

"With our new GLE Performance models we are transforming a 20-year tradition into the future. For the first time we are electrifying our well-proven 4.0-litre V8 biturbo engine with an EQ Boost starter-alternator and a 48-volt on-board electrical system. As such we are embarking on another new chapter of our drive technology, which we are also successively extending further to other model series as we move towards electrification and hybridisation. With our new premium SUVs, our customers can look forward to an unrivalled package of Driving Performance, high day-to-day suitability, optimum traction on practically all surfaces and also comfort on long journeys with high levels of efficiency," says Tobias Moers, Chairman of the Board of Management of Mercedes-AMG GmbH. 

With the EQ Boost starter-alternator for the first time: the AMG 4.0-litre V8 biturbo engine
