Chevrolet’s new sub-compact offering makes its North American Debut later today as the Sonic, but the Detroit automaker is also set to take the covers off a tricked-out version of its new hatchback. Later today at the 2011 Detroit Auto Show, the Chevrolet Sonic Z-Spec will make its official debut.
Outside, the Z-spec is immediately differentiated form the pedestrian Sonic by its four-piece body kit, massive rear-deck spoiler, and orange paint scheme. Front and rear lighting is reminiscent of the Aveo RS concept displayed at the Detroit show last year. Eighteen-inch multi-spoke BBS wheels are painted in bright orange and wrapped in performance Michelin rubber. Residing behind the new rollers are four-piston Brembo calipers that grab hold of drilled rotors. Unfortunately the upgraded equipment is only featured upfront, as stock drum brakes are still found in the rear.
The exterior color scheme is carried into the interior, where orange stitching is found throughout. Heavily bolstered Recaro seats are covered in tan leather, along with a matching shift boot and steering wheel inserts. A new billet shift knob and flat-bottom steering wheel cap off the subtle interior upgrades.
No information was given about the Z-Spec’s powertrain, but we suspect a hotter version of the stock turbocharged 1.4-liter I-4 to be found underhood. A new K&N filter and Borla exhaust help the Sonic to breathe better, while giving a more aggressive growl. Although billed a concept, we wouldn’t be surprised to see the Z-Spec become a new model in the Sonic lineup, with the new body components making their way into GM’s order guide at the least.
