Click above to watch the Audi Q7 V12 TDI take on the BMW M5

Autocar decided to find out which was faster among two unlikely bedfellows sharing one common trait: 500 horsepower. In one lane you've got the BMW M5, with ten petrol-powered cylinders. In the adjacent lane there's the Q7 V12 TDI, with twelve oil-burning cylinders. The M5 is much lighter. The Q7 has Quattro. And being England, of course it's wet. Follow the jump to see who won and by how much.

      Pointless but neat.

      The Q7 is so huge.
        • 5 Years Ago
        I dont think it was meant to be fair. Show you that such a lopsided competitor can almost hold its own.
        • 5 Years Ago
        snicker snicker, aerodynamics of a house :).
        • 5 Years Ago
        agreed.. thts not a fair competetion.. q7 is huge
      • 5 Years Ago
      Wow. A British publication giving the BMW the nod. Whoddathunkit? Next they'll become pro-Ford or something...

      • 5 Years Ago
      Given the size of the Q7, the fact that it has the "aerodynamcis if a house" yet can still hang with the m5 is pretty impressive in my books.

      **Yawn**...notice 2 things.

      - No growl from the M3 exhaust...has anyone ever heard an M5 at full throttle that close? Yeah, just a slight difference in sound, lol.

      - Enough water on the road to make an all wheel drive SUV break traction with a revamped electronic differential and sport mode (which still uses a stability control system)...yeah...the fact that the M5 could launch at all surprises me.

      ...so in typical fashion, a ridiculous scenario played out as a "competition", the Q7 would not even come close in an optimal "drag race" scenario, which hurts to even say to begin with when speaking about an M division car.

      People can actually drive modern BMWs? I thought they were automated already? (read sarcasm)
      • 5 Years Ago
      That's amazing. Plus 700+ lb-ft = *drool*

      I can start ripping houses out of their foundations with this beast.
        • 5 Years Ago
        No low range though.
      • 5 Years Ago
      edit: No, but at least beat it out of the hole.
      • 5 Years Ago
      When I first read the title I thought it was the X5 M against the Q7. That seems like a race more people would be interested in.
      • 5 Years Ago
      Love both of them.

      If i've learned anything from this test, it's that the audi quartro awd system in this suv must suck.
      No way in hell a rwd sports sedan should get out in front of a 500hp awd suv from the get go, then hold that position on wet pavement.

      I've read other places that this audi is supposed to be 11 second capable, ya right. More like high 12's if they are lucky.
      I would like to see the audi vs the srt8 cherokee.

        I don't know if the driver brake torqued the launch (seems like he flubbed that)?

        What 'system'?
        Engine drives transmission, which drives torsen3 center differential.
        The front differential is probably an open differential. I'd hope that the rear would be a torsen2, but there is a good chance that it is also an open differential.

        So if open front/rear differential, the truck will spin both tires on the same side. and this is where brake actuated traction control comes in.
        • 5 Years Ago
        Umm, I think the fact that the Audi weighs roughly 1700 lbs. more than the M5 *might* have something to do with that...
        • 5 Years Ago
        Ummm.... that might be some of the worst logic I've ever heard.

        The quattro system is clearly working to make the 3 ton vehicle nearly as fast as the 2-ton vehicle.

        If you think that 700lb-ft can be applied to the rear wheels of a vehicle where all the wieght is up front and not just sit there and spin... you're nuts!

        Quattro FTW!

        What you should know is that the Audi probably had the traction control on. He said the Audi still spun all the wheels even though it was AWD. If traction control is in fact on the power is cut off instantly until the car gains traction. It happens all the time in my A6 when it is wet and I accelerate too quickly on a turn. It just cuts the engine speed to about 1200rpm until i get traction. Then it goes.
        • 5 Years Ago
        I'm well aware of the weight, but if an awd performance vehicle can't get out in front of a rwd performance vehicle in wet conditions, what exactly is the point of own something awd?
        Would i expect it to hold the lead? No, but at beat it out of the hole.
      • 5 Years Ago
      The M5 would have been considerably further ahead if it was dry... there is no way a 4000+lbs RWD sedan on street tires can do anything better than 5seconds from 0 to 60mph in the wet, no matter the power output.

      But that V12 TDI Q7 is one fast living room on wheels! Caddy should drop the LS9 into the Escalade... some fair competition.
      • 5 Years Ago
      I almost typed that I'd rather have the V12 TDI Q7, but then I realized that's insane.
        • 5 Years Ago
        Still closer than I thought.
