Motor Trend Senior Features Editors Jason Cammisa and Jonny Lieberman are in a bind. Before having driven Alfa Romeo's first rear-wheel-drive sports sedan in 30 years, they didn't know what its closest competitor would be. So they brought all of them: a 2016 BMW M3 Competition Package, a 2016 Cadillac ATS-V, and a 2016 Mercedes-AMG C63 S.

Then, the duo hit the road to see which is the best midsize luxury sport sedan.
