Do you remember that kid on the playground? He was kinda small, a little unruly and didn't appear to have much to contribute? The CLA45 AMG is kinda like that. In the best way possible. It's spry, doesn't quit and perhaps has a chip on it's shoulder.

Handcrafted and signed by its own master engine builder, the V-8 heart of the 2015 Mercedes C63 AMG 507 Edition generates best-in-class output: 507 hp and 457 lb-ft of torque. Developed entirely by AMG, it features such race-proven technology as a rigid one-piece aluminum bedplate, plasma-sprayed cylinder bores, and self-adjusting bucket-type valve follower.
