Getting 5400 pounds to behave like a high performance car is a feat in of itself. That is what Mercedes has accomplished with the new GL63 AMG S which is basically just a reskinned ML63. It is the Mercedes-AMG answer to their competition over at BMW which is the X6M.
Head 2 Head compared the GLE63 AMG S and the BMW X6M and picked the X6M as the victor. Indeed, the X6M is the higher performance SUV of the two.
That is not to say the GLE63 AMG S is some slouch. It is very spry considering it carries 5397 pounds. The 5.5 liter twin turbocharged and direct injected M157 V8 hustles the beast to 60 miles per hour in 3.9 seconds. The 1/4 mile flashes by in 12.5 seconds at 112 miles per hour.
It is insane for something this big and heavy to move that fast. Car and Driver also records a .95g skidpad figure so it holds the road quite well.
That big engine with 577 horsepower and 561 lb-ft of torque does not come without a price. Car and Driver recorded 13 miles per gallon in their testing. Heh, aren't the Germans supposed to be all about efficiency these days? It is hard to make that argument when they are producing twelve second 5000+ pound SUV's with around 600 horsepower (they sandbag the power ratings on the turbo motors).
The BMW X6M is slightly lighter on its feet carrying roughly 200 less pounds and accelerates quicker. It also handles better. Are the people in the market for either of these really going to care about a tenth here or there? Of course on this network we do care but we wonder if the soccer mom driving one knows the X6M is a few tenths quicker in the 1/4 mile. Both are hugely capable and it comes down to personal preference.
It is hardly an efficient vehicle but we love it. It is not anywhere near the heaviest performance SUV AMG produces. When it comes to moving heavy cars quickly few do it as well as Mercedes.
