This is the pinnacle of pure all wheel drive hooliganism. The BMW X6M versus Porsche Cayenne Turbo. Combined, these two bring an astounding 1055 hp and 1016 ft-lbs of torque to this heavy weight German comparo.
Since its introduction as a 2010 model, the BMW X6M looks have been polarizing. Why would you want a 5300 lbs Sport Ute that has less utility than an X5 and costs more? Good question. One could also question the need for a Porsche Cayenne Turbo as it costs more than twice the $48,850 starting price for Cayennes. Realistically, there is no rational reason to own either of these insane sport-utes. Accordingly, Top Gear Australia says people who drive these sort are Tossers.
German Engineering.
The Germans are on to something here though, because I didn’t care if people thought I was a tosser or not when I was driving them. The thrust capable from the Porsche and the BMW is an automotivejunkie’s crack. I would slow down or wait for traffic to clear just to nail the throttle unleashing their turbocharged V8s which then channels power through all four wheels. It literally felt like they were clawing at the pavement when launching them from a dead stop. It’s an amazing feat what BMW and Porsche have done to make both of these SUV’s so rewarding to drive. Both also offer that classic SUV experience of a commanding view and seating position in gorgeous leather lined, tech infused cabins.
Starting with the BMW, one finds that all the chassis aides are included. These include Dynamic Performance Control (DPC) which is a trick differential that instead of braking the inside rear wheel in a hard turn adds power under throttle to the outside rear wheel. Fairly complex and impressive, given so many manufacturers choose to just use selective inside wheel braking to fake it. Next there’s EDC or Electronic Damper Control, Active Roll Stabilization and DSC (Dynamic Stability Control). Frankly there are just too many settings for me but thankfully the only thing you need to do is hit the M Button on the steering wheel to put it in Maximum M fun mode! Power is split 40% front, and 60% rear until the xDrive sense some slip, then the X6M can vary power distribution as needed to help grip and powering out of corners.
In its typical way Porsche serves from an ála carte menu, so most chassis aides are extra, until you get to the just released $146,000 Cayenne Turbo S. Porsche does one-up BMW with the Turbo’s height adjusting suspension system, which comes standard. This can vary the ground clearance from 6.2” up to 10.6”. The BMW’s height is not adjustable, though is 10mm lower than a standard X6. At the Cayenne Turbo level, Porsche’s Active Suspension Management (PASM) is included. On the Cayenne Turbo, I just don’t get why they make the Porsche Dynamic Chassis Control (PDCC) and Porsche Torque Vectoring (PTV) optional. PDCC is Porsche’s version of Active Roll Bar management and PTV is their version of BMW’s Active Differential (DPC). Porsche also has their alphabet soup of drivers aides PSM, ASR, ABD, EDTC. Enough acronyms between the two of these to give one a headache.
The Cayenne Turbo’s standard choice for wheels and tires is curiously 265/50/19 on a 19×8.5 square set up. Why one would suddenly choose to become rational at this point of purchasing a Cayenne Turbo with a taller side wall and less expensive all season tire just doesn’t fit. If you’re going to be a tosser, go all in and order the optional Porsche 21” 911 Turbo II wheels seen in the pictures of the black one with the low profile sidewalls and sticky summer rubber. BMW comes standard with some aggressive rubber shod on 20×10 wheels and 275/40/20 tires on the front with 20×11 wheels and 315/35/20 tires on the rear. That’s what I am talking about!
Technology and Gadgets.
The tech in the BMW X6M is outstanding. It starts with a well sorted and standard iDrive/NAV with a large 8.8” screen. Head-Up display is a must have option in the X6M with its wicked arching dynamic colored rev band and gear selection indicator being projected in your line of vision. When the driver is not wringing out the X6M, the Head-Up display is best in the business at showing you up coming navigation turns. BMW also has an optional camera system with top and side view to show you exactly what is surrounding the X6M when parking in tight spots because, well, um there’s very little rear visibility in the thing. Thankfully park sensors are standard. BMW Apps is an inexpensive and well worth it at just $250. For more info on BMW Apps click here.
Porsche’s tech in some respects exceeds BMW and in others falls short. Probably the coolest thing Porsche’s tech gurus have done is make the cluster on the right of the tachometer a configurable multifunction display in addition to their center mounted 7” display. You can make the multifunction display NAV, oil level, among other or even all four tire’s pressure to the PSI. Here Porsche provides the driver a live readout of tire pressure. I’ve even used the display to watch the PSI rise when I had to add a bit of air to the tires on the Porsche Cayenne Turbo. Where the Porsche falls short in my mind, is that overall PCM (Porsche Communications Management) is more cumbersome to use. It’s easy to get lost in its sea of buttons and knobs below center NAV touch screen.
The Cayenne does have a back up camera but not the slick top and side views that BMW has. Also, Porsche doesn’t have anything even close to BMW Apps either. Wait. Hold the phone, as of November 2012 production, Porsche started offering a $210 option that will add “Online Services” smartphone integration similar to BMW Apps. Both Germans can stream music via Bluetooth.
The Porsche Cayenne Turbo was completely redone for 2011. The interior has an ascending center console with a Panamera style cockpit. Typical Porsche there is nearly unlimited ability to customize it which BMW cannot match here in the United States, though can in Europe via BMW Individual. The Cayenne Turbo’s cabin is a very, very nice place to be. My only real gripe is that Porsche sells two different steering wheels with shifting controls that are completely opposite. I much prefer Porsche’s optional paddle shifter to their thumb button push/pull standard wheel even if you can’t have audio controls on paddle shifter version. Pull the right paddle on the paddle shifting wheel and you shift up. Pull the shifter on the thumb (dumb) version on the right and you shift down. It absolutely drives me nuts. Thankfully, Porsche will let you option either one, and if you didn’t spec your P car, you can buy one from the parts counter to switch to your liking.
Driving Experience.
Driving these two revealed their biggest difference. Though both are ridiculously fast for their size, the Cayenne Turbo does so in a more reserved manner. Almost like non-stop electric motor pulling it forward. The cabin is well isolated from road noise, perhaps too quiet. The X6M, on the other hand, was an outright raucous blast. Wicked burbling between shifts, almost like it was blipping the throttle between shifts on its 6-speed auto. Both have the ability to be driven sedately and do a good job at it. The BMW gives you more a sense of speed and feedback from the road with its hydraulic steering. It’s a physics defying experience to chuck the X6M into a corner and blast out of it.
There’s really nothing wrong with the way the Cayenne Turbo drives, it is just a bit reserved for what I see is such an outrageous machine. Maybe a good analogy is like the difference between a 911 Turbo and a 911 GT3, both great cars just different experiences. The Cayenne Turbo is a crazy fast machine but the experience is more isolated, less rough, you up get in a fight experience you can get from hammering an X6M. Road and Track noticed the same murky handling that I did, noting in February 2013, that the Cayenne Turbo is “still confusing, partly because you can approach a corner the same way twice and get wildly different results. The Cayenne also has a habit of jumping around under throttle. It’s not that the throttle itself is jumpy; the Cayenne’s whole back end hops around, seemingly indecisive as to which corner it should direct asphalt-melting quantities of torque.”
The other interesting thing I found was that Road and Track noted that the Cayenne actually weighed 5210 lbs, well over the MFR stated weight of 4785 lbs.
