BMW X6 M or Mercedes AMG GLE 63?

So let me start by saying that both of these vehicles are amazing. They are both some of the most unnecessary and yet the coolest and most overdone SUV's. Let's start with the X6 M though because it was the first of its kind. It was the first "SUV Coupe", or the first vehicle to really have this look and form and go on the market. It is an M vehicle to it has lots of power and is crazy sporty for a BMW. This is why it became pretty popular. It is an extremely sporty SUV and it is just so unnecessary that it is awesome! They sold extremely well and this is why eventually, Mercedes decided to get out the tracing paper. They soon came out with the Mercedes AMG GLE 6
3 Coupe to directly rival the X6 M. In fact, the GLE looks exactly like the X6, just translated into the current Mercedes design language. As you can see here, they look very similar.

Since they look so similar, it's hard to say which one looks better. I think that on topic it is just a matter of opinion. Personally, I think that the X6 M looks a good amount better than its competitor. This is just a matter of opinion though and some people may see it differently.
Now, onto specs. Both of these vehicles have some really crazy specs. So, we'll start with the BMW. It has a 4.4 Liter, turbo-charged, V8 engine that creates 567 hp. That's is an insane amount for an SUV of this size. It does 0-60 in just 3.8 seconds. That is getting into sports car region. This SUV will top out at 156 mph though. The next is the Mercedes and this has a similar engine to the BMW. It has a 5.5 liter, turbocharged V8 as well, except its it bigger and makes 575 hp. It will do 0-60 in 4.3s though, which is significantly slower than the BMW. That's still quick, just not as quick. The Mercedes is also limited at 156 mph though they have a package that will limit it at 174 mph. That is an optional package.
I think that overall, the BMW is better. The X6 M has better looks, better specs, and is more extreme. The Mercedes may be more luxurious and sound better but they just cannot compete with the M cars. The specs for the X6 M, especially the 0.5 second difference in 0-60 times, is just too much. The AMG GLE is just too slow. AMG does make good engine that perform and sound awesome, but the M engine performs better. That is why the winner of this battle is the BMW.
