Subaru's Forester was all-new last year, and sales have been soaring: It's up over 40% through August. Source: Subaru.

Last week, Subaru's U.S. division raised its sales guidance, saying that it now expects to sell 500,000 vehicles in the country this year -- an increase of 40,000 from its earlier guidance.

There was a good reason for Subaru to raise its guidance: Its sales have been booming. Through August, Subaru's U.S. sales are up 18.6%, far ahead of the overall market's 5.1% average increase -- and far ahead of most of its rivals.

What's driving this big boom for Subaru? As the Motley Fool Motor Money duo of John Rosevear and Rex Moore explain in this video, it's simply a matter of having the right products at the right moment. Compact and midsize "crossover" SUVs have been in high demand; Subaru's Outback is brand-new, and its much-acclaimed Forester was new last year. Customers have been flocking to its dealerships as a result.

There's more to the story, of course. Check out the video for the full scoop.
