    Head 2 Head compares the C292 Mercedes-AMG GLE63 S coupe to the BMW F86 X6M

    The Mercedes-AMG GLE-Class has two variants. The standard W166 GLE and the C292 'coupe' version of the GLE. The coupe is a direct response to the BMW X6. The GLE63 AMG S being the direct response to the BMW F86 X6M. Each is just another way to squeeze out a variant from a production platform and Mercedes wanted a piece of that pie.

    It works. It works very well as the SUV crazy environment these days eats these vehicles up. The high performance versions also tend to sell very well. That is simply how it is today. It is easier to get BMW to produce multiple M SUV's than M cars. We are still waiting on that Z4M.

    These two vehicles are actually pretty similar. They are heavy at over 5000 pounds, about the same amount of money, feature twin turbo direct injected V8's, and have automatic transmissions (ignore MotorTrend's 7-speed manual mistake on the GLE63 it is a 7-speed automatic). The BMW has the smaller S63TU V8 engine at 4.4 liters which is rated at 567 horsepower and 553 lb-ft of torque. The GLE63 AMG S (there is no standard GLE63 AMG) feature a 5.5 liter Mercedes-AMG M157 V8 rated at 577 horsepower and 561 lb-ft of torque.

    They both have direct fuel injection, both have twin turbochargers, and both are at 10.0:1 compression. BMW makes up for its displacement deficit with a trick manifold featuring top mounted twin scroll turbos and by revving higher.

    So which is better? The transmission of the GLE63 is criticized. They say it seems to not be in the right gear but a 7-speed should keep the revs low on the highway. Maybe AMG needs to works on their programming or MotorTrend just needs to click a button to get in the right gear. Maybe a little bit of both. The BMW gets the nod in the transmission category.

    They spend a lot of time on the parking ability of these cars and their assist systems. If you can not park an SUV what the hell are you doing driving one? Aren't these performance SUV's? How about some performance comparisons?

    Finally they get these vehicles on the dragstrip and a Camaro Z28 is thrown in for fun. The X6M wins the elapsed time battle but the Z28 is pulling harder at the finish line (as it should be). The GLE63 AMG S brings up the rear and it is surprising how much slower it is:

    X6M - 12.1 @ 114.3
    Camaro Z21 - 12.3 @ 116.1
    GLE63 AMG S - 12.5 @ 110.5

    The X6M is significantly quicker and faster. Add that to its lighter weight and better handling and you get a beatdown on the roadcourse. The X6M is 3.64 seconds quicker around Big Willow:

    The X6M is the better performance SUV. It certainly is interesting that BMW M makes sure it is the top dog in the SUV sphere yet they do not take the same approach to their M cars. The X6M is quicker, faster, better handling, you name it. Why does BMW insist on beating AMG decisively with its SUV's but not its cars?

    It's an odd world where the Ultimate Driving Machine company will not produce a driving machine to rival the AMG GT S but will gladly invest in making the best 5000+ performance SUV.

    The all wheel drive systems in the GLE63 sucks its a basic 60/40 split with open diffs nothing like the e63 4 matic that is 67/33 with an electronic limited slip rear diff. The x5/6m are clearly superior in driving dynamics and surprisingly gave it a beatdown in the acceleration test. They are still using the torque converter in the gle63. Big fail but I'm sure they'll sell like hotcakes

    The X6M has a torque converter as well. You want this if you want actual towing capability.

    Yes i meant in comparison to the mct they use in the rest of the range. The 8 speed zf further tuned by the m division is a much better trans than the old 7 speed 7G they are using in the gle63. From videos I've seen the response and shift time in the x5m is blazing fast

    Perhaps. They are honestly pretty similar physically. The X5M and X6M are just better performance SUV's all around.

    For your torque split numbers are they backwards? Or do the 4matic's really have super fwd bias? If it really is 60F/40R and 67F/33R no wonder they get beat down by the bmw!

    Yea i mixed that up its the other way around. The 40F/60R setup on the GLE63 also has open diffs front and rear just a bad design for a "sport SUV"

    Mercedes GLE.... Its a bad copy of the X6M.... and the rear looks like Volkswagen Passat.
    I own few Mercedes cars and can't accept why Mercedes copied it.
    Had done their own model.

    It is their own model. It's a copy as much as the 6-Series Gran Coupe is a CLS copy.
