BMW X6

Update: Here is why there is a difference between the diesel engines 

We came across an internal document issued by BMW which shows several comparison statistics between the upcoming BMW X6 and the alleged competition: the Porsche Cayenne and the Range Rover Sport. The results: the X6 is way ahead of its competition and wins in all the departments.

Unfortunately, we can not post the original pdf file so I will type out all the data for you. Let's start first with the comparison between the BMW X6 xDrive 35i and the V6 Porsche Cayenne. 

  BMW X6 xDrive35i Porsche Cayenne Range Rover Sport
Engine R/6 V6 No V6 gasoline engine
Capacity 2.979 3.598
Horsepower 306 290
0-60 MPH 6.7 sec 8.1 sec
Speed 150 MPH 141 MPH
Fuel Consumption 21.53 MPG 18.19 MPG
CO2 Emission 262 g/km 310 g/km
Dimmensions 192.15/76.35/66.58 in 189.04/75.96/66.94 in
Weight 4719 lbs 4917 lbs

As you can see, the X6 xDrive35i is 1.4 seconds faster, it consumes less fuel, it's less polluting and it weighs about 90lbs less. 

Winner: BMW X6 

Now the xDrive50i vs Cayenne GTS and the V8 Supercharged Rover

  BMW X6 xDrive50i Porsche Cayenne GTS Range Rover Sport V8 – Supercharged
Engine V8 V8 V8
Capacity 4395 4806 4197
Horsepower 407 405 390
0-60 MPH 5.4 sec 6.1 sec 7.6 sec
Speed 155 MPH 157 MPH 140 MPH
Fuel Consumption 18.17 MPG 15.54 MPG 14.76 MPG
CO2 Emission 299 g/km 361 g/km 374 g/km
Dimmensions 192.15/76.35/66.58 in 189.04/75.96/66.94 in 188.50/78.07/71.33 in
Weight 4983 lbs 5060 lbs 5786 lbs

Once again, the X6 powered by the V8 xDrive 50i is about 0.7 sec faster than the top Cayenne GTS and…2.2 sec faster than the Rover Sport V8 Supercharged. On top of this, once again, it burns less fuel, less emission rating and it weighs 4719 lbs vs 4917 lbs and 5786 lbs.

Winner: BMW X6 

Diesel Engines 

  BMW X6 xDrive30d Porsche Cayenne Range Rover Sport TDV6
Engine R6 No Diesel V6
Capacity 2993   2720
Horsepower 235   190
0-60 MPH 8.0 sec   12.7 sec
Fuel Consumption 28.62 MPG   23.70 MPG
CO2 Emission 217 g/km   265 g/km
Dimmensions 192.15/76.35/66.58 in   188.50/78.07/71.33 in
Weight 4730 lbs   5566 lbs

Even in the diesel market, the X6 xDrive30d is the king.

Winner: BMW X6

  BMW X6 xDrive35d Porsche Cayenne Range Rover Sport TDV8
Engine R6 No Diesel V8
Capacity 2993   3628
Horsepower 286   272
0-60 MPH 6.9 sec   9.2 sec
Speed 147 MPH   130 MPH
Fuel Consumption 28.27 MPG   21.14 MPG
CO2 Emission 220 g/km   290 g/km
Dimmensions 192.15/76.35/66.58 in   188.50/78.07/71.33 in
Weight 4807 lbs   6039 lbs

WOW, 2.3 sec faster?? Clearly, the R6 diesel engine is better than the V8 offered in the Range Rover Sport.

Once again  Winner: BMW X6

I know this is a document issued by BMW, so I'm still curious to see some tests done by car magazines to find out if these numbers stand.

The only thing we're missing now is the pricing, maybe the Chicago Auto Show will bring something new.

  2. These charts are comparing apples and oranges. The BMW is NOT a proper offroader. Critically, it lacks a low range case, locking differentials, and height adjustment that the Porsche and Rover have. The BMW would get stuck on a golf course. Compare it to other crossovers and grass and gravel SUV’s like the Jeep SRT8 and the Infiniti FX and the Mercedes ML63 and you will be less impressed with the bimmer.

    This is a ridiculous comparison. Of-course the 6 is going to win on roads. The PC should fair better and if the appropriate model were here would. The RRS is an off road truck, not a street racer. Stick a 6 next to a RRS on the side of a mountain and lets see the results. Notice the didn’t include the X5? What a joke.

  8. Elclair says:

    This is an uneducated comparision, the BMW Xdrive50i has a Twin-Turbo charged engine while the Porsche GTS is naturally aspirated, the BMW’s have no off-road capability besides its ground clearance. Compare the Xdrive50i with the Cayenne Turbo (which is comparing apples with apples since both are twin turbo V8’s) and the X6 will get decimated in EVERY apsect. The X6 is nothing more than a raised, over-glorified, stationwagon.

  10. Wrong info!! says:

    Cayenne 0-60 : 7.5sec not 8.1
    GTS : 5.7sec not 6.1
    don’t lower others to gain self asteam=]
    not to mention results compared off-road

  11. Wrong info!!2 says:

    guess what, found more
    X6 xDrive35i 0-60 : 6.9 not 6.7
    X6 xDrive50i : 5.6 not 5.4
    info from both maker’s offical site

  12. Horatiu B. says:

    @Wrong info!!2: The numbers came from an internal BMW document and we did not made them up. Now, I agree that BMW might have been a little conservative when it comes to the competition’s numbers, but from what I know, they do tend to test all the cars, including the competitors’, thoroughly, so they might be true. Also, this was an internal document, so not a marketing scheme.

  13. [...] Konkretnie chodzi o BMW X6 xDrive50i (oraz Cayenne GTS). Dominacja dokonana z mniejszego silnika o większej jednak mocy niż Porsche. Również porównując BMW X6 xDrive35i z Porsche Cayenne (3.6) bawarski samochód biję na głowę … [...]

  14. carlo cruz says:

    both the bmw x6 and the cayenne are both road bred vehicles no question abt that but in general only the RRS can live in both habitats so do the math guys., take a look at the bigger picture. functionality wins.

  15. biggie says:

    this information is bullsh*t. the X6 cant go off road so it dosent count as an off-road SUV . got somthing to say …?? wittle baby wanna cry ??

    so you can go —- yourself and i know that range rover is da best .

    and please dont put FALSE INFORMATION on the internet , put it in your wittle play book ok

  16. tom says:

    this is the worst review i have seen in my life, everything is completly wrong for a 2008 article. The porsche cayenne actually does 0-60 in 7.5s and since 2008 when it says the article was produced they inroduced a diesel.

  17. spencer says:

    ok first of call, your comparing bmw X6 to the base model of the porsche cayenne, and the range rover sport. I would like to see bmw X6 go up againts the porsche cayenne turbo S and the range rover supercharged.
