Ever since the second-generation Chevrolet Sonic burst onto the scene in 2011, we’ve seen the loveable hatchback become a staple at the SEMA Auto Show. We’ve seen it dress up as the Rocky Carmichael All-Activity Concept. We’ve seen it show up as the Sonic Boom Concept. Heck, we’ve even seen it come to SEMA as the Z-Spec 4D Concept. This year, the Sonic returns to the biggest aftermarket show in the world in the guise of the Sonic Performance Concept.
