We dig super sedans. You get 94 percent of the performance of a sports car (or there abouts) plus the ability to take a few friends along for the hair-raising ride. Also, cops don't seem to scrutinize big snazzy sleepers as much as they do bright yellow scissor-doored whatchamacall'em-ardos. It should come as no shock then that when we first heard about the new Alpina B7, we were pretty excited. When we then subsequently learned that an all-wheel drive version of BMW's sportiest big sedan was coming to the New York Auto Show, well, our excitement grew.

Then we saw the car in the flesh.

Let's just say we're now triple excited. A few pertinent stats, if we may. The 4.4-liter twin-turbo V8 found in a host of BMWs has been significantly improved to 500 horsepower (up by 100 hp over stock) and 516 pound-feet of torque (up by 66 pound-feet). The B7 is also more aerodynamic than your garden variety 7 Series, comes with zillion-spoke wheels (fine, twenty) and can hit 60 mph in 4.5 seconds. With the Alpina B7 xDrive, you can now toss AWD into that already frothy mix.

But the above stats aren't the crazy parts. It's the details that impress the most. For example, all four of the heavy-duty half shafts come out of the 7 Series High Security. The 60 to 0 mph braking distance is identical to a Porsche Turbo. That last bit is not an April Fools' joke, although it's somewhat mitigated by Alpina's saying, "that's cold braking distance." While not a stat per say, the AWD system is mechanically identical to other BMW xDrive systems, though Alpina has written their own software system, presumably for the better.

One last thing that's actually a little to complicated to explain: take a look at the center of the B7's wheel. You'll see that once you've slid the heraldry over, there's a keyhole. Now, if you zoom out, you'll notice no valve stems anywhere on the wheel. In other words, your tire pressure's locked in and can be adjusted to the tenth of a PSI.
