Alpina unleashes its latest luxury sports tourer, a BMW-based sedan for the performance-minded cognoscenti

Explaining the Alpina B5 is no easy task: It produces more power and torque than the BMW M5, and both cars are based on the same F90 generation of 5 Series, but Alpina promotes the B5’s comfort and refinement as much as its performance. It’s an AMG rival in America, an Audi RS competitor in Europe. Also, it’s exclusive in Australia, and likely to remain so, despite being priced significantly lower than the M5.
