The 2010 BMW 750i with the xDrive system gets reviewed by several journalists from Automobile Magazine. Each one of them puts the car through different driving scenarios and some of their short reviews are embedded below.

Starting in the 2010 model year, BMW xDrive is available for the first time also in the BMW 7 Series. Through a power divider with an electronically controlled multiple-plate clutch, xDrive feeds exactly the right amount of power in every situation to the axle which, through its wheels, has the best grip on the road.

Through its dynamic operation, xDrive also helps to give the new luxury performance models with this technology the neutral behavior in bends and tracking stability. In bends more drive power is fed to the rear axle in order to make the car even more nimble and avoid any understeer.

In the process the operation of xDrive is based on the steering angle pre-determined by the driver. While, when driving smoothly in a straight line, the front-to-rear power split is 40:60, up to 80 per cent of the drive power goes to the rear axle in a bend, ensuring spontaneous steering behaviour precisely following the actual radius and course of the bend. Then, when leaving the bend, the distribution of drive power returns to normal in the interest of maximum traction when accelerating again in a straight line.

The combination of a rich, luxurious interior; a smooth, powerful engine; and truly refined road manners make it hard to top a BMW 7-series when it’s time to embark on a road trip, so I was more than happy to sign out the 750i xDrive for my journey to Michigan’s west coast for the weekend. Because the occasion was a high-school reunion, I plugged in my iPod and chose a classic rock playlist so that I could aurally transport myself to the late 1970s. Turns out, though, that was the only thing that reminded me of the ’70s, because the 7-series is a true twenty-first-century car packed full of state-of-the-art technology. Thirty years ago, it would have been hard to fathom a car like the modern 7-series. Of course, thirty years ago paying $100,000 for luxury BMW sedan would have been hard to fathom, too.

And a second one.

On nice summer days like those we occasionally get in Michigan, it’s almost impossible to tell if a 7-series has an xDrive all-wheel-drive. Despite a 150-pound weight penalty versus the base rear-wheel-drive 750i, the driving experience of the xDrive-equipped car feels almost the same, which is to say, surprisingly sporty for such a large car. The fuel-economy penalty is a bit more noticeable, though, as xDrive makes for a fairly significant hit at the pump, with the EPA fuel-economy rating 1 mpg lower in the city and 2 mpg less on the highway (14/20 mpg city/highway versus the RWD car’s 15/22 mpg).

Still, even southern Michigan’s winters don’t really necessitate all-wheel-drive luxury cars like the 7-series or the 4Matic edition of the Mercedes-Benz S-class (winter tires and rear-wheel drive with stability control are usually sufficient). But in snowier climes, that extra edge can make the difference between getting there and not, particularly if “there” is up your steep driveway. By the way, this is the base xDrive 7-series, as the new six-cylinder 740i/Li will not be offered with all-wheel drive.
