The 2012 Chevrolet Sonic made a splash at the 2011 SEMA show, with several concepts that demonstrate the many possibilities for owners of this subcompact. The Z-Spec line of accessories from Chevrolet accounts for many of the tweaks, from wheels, aerodynamic body kits, sport pedals and upholstery options, to performance suspensions, exhaust and braking systems. The Sonic, which is just now on sale, is currently the only car in its class to offer a factory-fitted turbocharger, making it a perfect candidate for customization.
At the radical end of the scale is the Sonic Boom concept. Basically, it’s a massive Kicker 4,000-watt audio system on wheels, with a few Z-Spec additions thrown in. Open the tailgate and it looks like the car could be propelled by sound waves alone, thanks to 12 speakers, two of them 15-inch sub-woofers.
