BMW M5 Runs Rings Around C63 AMG at Worthersee [Video]
Don't know what we're talking about? How about this red rooster of an Audi A6, or the yellow dandelion of an RS4. These two cars also got our attention, especially that slammed E60 BMW M5 on concave wheels.
You've seen some excellent stills of the cars. But have you guys seen an M5 doing donuts around a C63 AMG which is itself doing a burnout? These guys are clearly insane, but in a good way.
