There's not just an AMG for every type of customer in 2019; these days there's an AMG SUV for every possible family size and lifestyle, too. From the quirky little GLB35 to the mother-of-fury G63. And now the range is getting an additional refresh, with both the GLS and GLE 63 models unveiled in LA.
The headline news for both cars is the update to the 4.0-litre twin-turbo V8; for the first time it gets the EQ Boost mild hybrid technology pioneered in the '53 electrified models, adding 22hp and 184lb ft via an integrated starter-alternator. Peak power is now 612hp; peak torque for GLS63 and GLE63 S is 627lb ft, sufficient for 0-62mph times of 4.2 seconds (GLS) and 3.8 for the GLE. Both use the AMG Speedshift TCT 9G gearbox, getting power to the road via AMG Performance 4Matic+ all-wheel drive with fully variable torque distribution and an electronic limited-slip diff at the rear.
The similarities continue underneath, with both GLE and GLS underpinned by Merc's AMG Ride Control+ with adaptive damping that's controlled through Dynamic Select - amongst a host of other parameters - through Comfort, Sport and Sport+. Thanks to the introduction of the hybridised drivetrain there's sufficient juice for a 48v active anti-roll system, which is said to ensure body movements "can be actively and optimally adapted to the driving status, which intensifies the driving experience."
In fact, there's little to separate the two dynamically - at least in terms of equipment - with GLS and GLE both boasting speed-sensitive steering and chunky brakes: 400mm front discs are standard on both cars. Although the more sporting GLE has the option of a ceramic upgrade, identifiable by bronze calipers.
Thereafter, the differences become more obvious - especially if you take into account the relative market positioning. The GLS is pitched as "the S-Class among SUVs" while the GLE is "where extreme sportiness, first-class off-road characteristics and absolute day-to-day suitability come together." Which means the GLE gets a Race mode that the GLS does not; the larger car receives a Burmester sound system denied to the smaller one; and with the 'Supersport' start-up menu activated on the GLE, the driver can see engine data, a G-meter and a race timer - good luck finding those on the seven-seat GLS and its "exclusive appointments."
Both are distinguished from the standard range offerings by their AMG styling features, with 21-inch wheels as standard, a "dynamic jet-wing" design of front apron, flared arches, AMG diffusers with chunky zorsts and prominent rear spoilers. The interiors follow a similar theme, the MBUX infotainment complemented by nappa leather, an AMG three-spoke wheels, stainless steel pedals and various (optional) Energizing Packages, for when 612hp isn't energetic enough.
Ultimately, separating GLE and GLS 63 is - somewhat unsurprisingly - like separating E and S63. One is larger and more luxurious, the smaller one likely to be sharper to drive and a tad faster. The choice is most likely to come down to taste and budget, and whether the requirement is for four passengers or six. Because given AMG's recent run of form with this engine and four-wheel drive, you wouldn't bet against them being really quite good. Oh and welcome to the era of the hybrid AMG V8...
