Amongst the treasure trove of tuning that Chevrolet has brought to SEMA this year, this pair of Sonic hatches is perhaps the most accessible. With one car tweaked for show and the other go, both halves of the SEMA ethos are nicely represented.
The Chevrolet Sonic Performance Concept has been fitted with the company's Performance Stage Kit, meaning cold-air induction for the 1.4-liter turbocharged engine and a new exhaust to let it breath more freely. The company tells us that the kit increases power, though it has declined to quantify that assertion, sadly. A track-tuned suspension means the performance Sonic rides lower and should corner flatter, too.
The second Sonic wears an Accessories Concept designation. The concept is essentially a test bed for appearance packages, with matte-black striping, white headlight and taillight rings, a new grille and fresh wheels.
