If ever there was such a thing as a clash of titans within the world of luxury automobiles, the event where the 2015 BMW X5 M went against the Porsche Cayenne Turbo by an Australian magazine would certainly be added into the codex of legends. You basically have two vehicles that belong in the most expensive and most powerful lines in the world, and it can be tempting to think that you know which would win when they go head to head.
Then again, this is not about which car is better. It’s about how they performed and how they compared when driven together.
So, for a little background, the X5 M has a V8, M TwinPower Turbo which is more powerful than their previous engine. At its peak, it goes for an impressive 567 horsepower and at 6000 or 6500 rpm. Its torque has also received a significant boost, putting it now at 553 lb-ft. As a result, you have versions of the BMW M line that goes from 0-60 mph in a whopping 4.0 seconds and can reach top speeds of around 155 mph.
Now for the Porsche Cayenne Turbo, we have the offerings of the Porsche car line that first broke through to belong amongst the most powerful SUVs in the industry. The latest models are armed with a twin-turbo, 4.8L, V8 engine which is quite powerful as well. Producing up to 570 horsepower and 590 lb-ft of torque, this is definitely one monster of a vehicle. It can do 0-60 in 3.8 seconds as well, at least according to the test that was done by the magazine.
Just to get an idea of what the magazine actually thought of the experience, here’s a little tidbit from their review.
“By the seat of the pants, though, both are similarly and ferociously quick. Any suggestion the extra 90 kilograms of heft the 2275-kilogram X5 M carries over the Porsche levels the performance playing field are pure semantics. Both SUVs have on-tap potency of such eye-opening magnitude that, when fully uncorked, sensible and responsible on-road application evaporates. It’s a very short and close race to the foul dark side of any Australian speed limit.”
By and large though, it was found that even as the vehicles presented considerable differences in how they handled, they were able to perform equally in many grounds as well.
