Spied: 2010 BMW 3-Series Crossover (F3)

As previously reported, BMW is believed to be working on a new crossover based directly on the 3-Series. Today, spy photographers caught the first glimpse at a test mule for this new vehicle. BMW engineers are using the body of a 330xd wagon on top of the new crossover's chassis.

Over half a year ago, company insiders reportedly said the new model -- codenamed F3 -- will probably arrive as a 2010 model.

While these photos don't tell us anything about how the F3 will look, they do confirm development is underway.

The vehicle will likely resemble the 3-Series, looking closer to a station wagon than the truck-like X3. The F3 is expected to target the Honda CR-V and the Toyota RAV4.

In early 2007, BMW CEO Norbert Reithofer apparently gave the project a "definite thumbs up," after years of deliberation by previous management. The car will provide the high seating position of a crossover with the space and layout of a traditional station wagon.
