The next BMW F10 M5 has recently been caught winter testing in Sweden. Judging by these spy photos, the tester has been equipped with snow tires and wheels, so those will not likely be the production car. However, the car has been in testing for around nine months now, so it's only a matter of time until the car makes its official debut, most likely at the 2011 Frankfurt Auto Show in September. Before that, a concept version will probably make an appearance at the Geneva Motor Show this March.
Other expected changes from the standard 5-Series include the typical M-enhanced front and rear bumpers, side mirrors, and larger wheels. Perhaps the biggest news about the new M5 is that it will no longer come with a V10. BMW has stated they're downsizing their engines as they attempt to adjust to growing government regulations, especially in the EU. The M5 will come with a V8 that's expected to generate nearly 30% more torque over the current V10. Photos courtesy of 5POST.com
