The Chevrolet Sonic Z-Spec, which are being evaluated for production, will be revealed at the upcoming 2011 SEMA Show. Z-Spec is a line of performance, styling and personalization accessories.

Chevrolet Sonic Z-Spec #1 – Designers took a turbocharged Sonic five-door and dressed it with concept Z-Spec accessories. They added Z-Spec ground effects, a spoiler, unique grille and graphics package – then finished it off with a Torch Red exterior and Z-Spec concept 18-inch wheels. Inside, the Cobalt Red cabin features custom trim, including perforated black suede seat inserts, a Z-Spec sport pedal kit, sport shift knob and a racing-style flat-bottom steering wheel. Additional upgrades include performance brakes with four-piston calipers, a new high-flow exhaust system and performance suspension parts.

Chevrolet Sonic Z-Spec #2 – In Flat White with Torch Red accents – builds on concept Z-Spec accessories with a more aggressive ground effects package, unique grille, rear spoiler and graphics package. It rides on Z-Spec concept 18-inch wheels and also includes a re-trimmed interior with Z-Spec sport pedal kit, Z-Spec sport shift knob and a flat-bottom steering wheel. It also features custom racing seats with the Z-Spec logo. The factory powertrain features the 1.4L turbo engine and six-speed manual transmission. Performance upgrades include brakes with four-piston calipers, a high-flow exhaust system and suspension parts.

Chevrolet Sonic Z-Spec 4D Concept – The more formal look of the Sonic sedan lends itself to a touring car-style motif, which this Ashen Grey Metallic concept picks up with concept Z-Spec ground effects, rear spoiler, grille, “Chevrolet” graphics and larger Z-Spec concept 18-inch wheels. As with its five-door counterparts, this Sonic features a re-trimmed interior – in Dark Titanium with Cobalt Red accents – Z-Spec sport pedal kit, aluminum sport shift knob and a flat-bottom steering wheel (trimmed with Cobalt Red suede). The factory turbo 1.4L engine and six-speed manual transmission are complemented by performance upgrades that include four-piston caliper brakes, a high-flow exhaust system and suspension parts.

Chevrolet Sonic Dusk – The most subtle of the Sonic concepts is the Dusk. It features a Berlin Blue exterior, with a mild concept ground effects package, unique grille treatment and 18-inch concept wheels in dark Galvano Silver. Even the lights are tinted blue for a sophisticated statement. The Mojave leather interior has custom seat inserts, Z-Spec shift knob with satin chrome trim, Z-Spec sport pedals and accessory interior trim kit. The Sonic Dusk also features a suede-trimmed, flat-bottom steering wheel, custom audio system and brake and suspension upgrades.
