Besides being faster from 0-100km/h, the BMW X6 xDrive50i was 7 seconds faster on the Nurburgring lap as well.
With a lower price, better fuel consumption and free 4-year maintenance, the X6 is a better buy. Sorry guys, as much as I like Porsche, the X6 takes the win this time.

 

Sorry, but the X6 looks like my balls. The front is okay, but the side profile and rear are

 

I like the X6, especially in Black. If the M version really does come out, I would be excited to see how that performs.

I used to have an X5, and it was one of the best cars I've ever driven all around. I drove the X6 and loved it as well. No other SUV feels the same way, and they handle great for being such large autos.

 

Cool, I love the X6 and would love to see an even faster version with some type of bodykit, skip the M badge though!

 

X6 it looks better and performs better than a Cayenne. We have a clear winner here

 

Even if the X6 had a V12 Quad Turbo with two million horsepower and the Cayenne was powered by a moped engine, and I had to dress up like a gay pride parade participant every time I drove the GTS, I would rather have that than an X6.

 

+1.

 

 

The X6 is hideous...

 

Sorry but the X6 just looks too clumsy and bulbous as if BMW doesnt have any projects and just pushed this and made it be the trendy or must have car of the summer, enough variants car manufactures should special in two-three models and just have them done right.

The last BMW which I liked was the Z8, the best 7 series to me is the one in the 007 movie back in 1997. The Bangle era is really hurting the BMW look, please BMW just release the 8series coupe.
