It's that time of year when seemingly every mention of a car has to prefaced with the phrase "all-new". And the all-new BMW X5 — or "All-New BMW X5"; the BMW USA website prefers to capitalize — is the latest all-new vehicle to roll off the same old production line.

BMW's already been highlighting the SUV's sporting credentials, by racing it around a Monza replica in the Moroccan desert. Most of us don't live in the Moroccan desert, though, and don't spend much time racing, so how's BMW supposed to appeal to Jane and John Q. Public over here?

The answer: by driving the X5 from the BMW factory in Spartanburg, SC, to the LA Auto Show. And because just taking Interstate 40 would be too easy for an SUV that should be able to handle slightly more varied terrain, BMW decided to do it in a perfectly straight line, whatever obstacles that might throw up.

As a little disclaimer, when BMW says a straight line, it doesn't actually mean a straight line. In the interests of making the project even slightly realistic, the route was allowed to deviate up to 10 miles either side of the line. Just to keep the X5 from having to plow through anybody's living room, or tackle insurmountable obstacles when a short diversion would be a better choice.

The 3,027-mile route took in a demolition derby in Tennessee, a barge crossing over the Mississippi and a Texan high school football game, as well as the cornfields and plains you'd expect to find in America's interior.

The trip ends with the X5 reaching Los Angeles; the video was produced on the road to allow it to be shown on arrival at the LA Auto Show. We can expect to see it being reused as a TV commercial some time next year.
