The Mercedes-Benz C63 AMG is a strong alternative to the BMW M4, as toe-to-toe, we preferred the Mercedes over the previous-generation M3 coupe in many respects.
Whether the next generation of the AMG C-Class will be able to bring the same level of fight to the new M4 remains to be seen.
Audi's RS5 is another possible pick in the high-performance sport-luxury coupe segment, bringing with it quattro all-wheel drive and the breathtakingly gorgeous lines shared by all A5-based models.
On the track, or otherwise at the limit, the RS5 may lack some of the bite of the alternatives, but it's by no means a slouch.
The Cadillac CTS-V coupe is in its final run; it's a reasonable alternative to the M4 if you can find one, but it's going away, to be replaced by the ATS-V.
Finally, Porsche's Cayman and Boxster are some of the most brilliant-handling machines in this set, especially in S trim.
They're our pick in this set, and the true sports cars among these entries, too.
