Chevrolet announced they have big plans for their small cars at this year’s SEMA with new Dusk and Z-Spec models.

Chevrolet will be displaying different Z-Spec kits on the Cruze and Sonic to evaluate them for production. They are paying a special attention to the Sonic, to emphasize on the potential of this small car for customization.

There will be a pair of Cruzes, the Z-Spec concept with 18-inch custom wheels, an accessory spoiler and a high-flow grille on the outside and special seat inserts, a racing-style pedal kit, accessory shift knob and interior trim, as well as a new steering wheel for the inside, and the Cruze Dusk with a mild concept ground effects package, a unique grille treatment and dark-tinted wheels. The interior has custom seat inserts, along with an accessory shift knob, sport pedals, interior trim kit, a suede-trimmed steering wheel and a custom audio system.

The program for Sonic is more substantial, and includes four different packages:

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.

Sonic Z-Spec #2 – The next Sonic concept – 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.

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.

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.
