Don’t mistake the Chevrolet Sonic for a wimp of a car because clearly, it’s got something to offer as far as the tuning market is concerned. The car is one of those that are considered aftermarket favorites and proof of that is Chevrolet’s intention of bringing a slew of modded Sonics to the 2011 SEMA Auto Show.

Arguably the most interesting of the four SEMA-bound Sonic models is the Z-Spec 4D Concept, a car that not only carries Chevy’s own Z-Spec package, but also a bevy of other upgrades. Aesthetically, the car has been dressed in an Ashen Grey Mettalic finish, complete with a refreshed grille, a rear spoiler, "Chevrolet" graphics, and a set of new 18" Z-Spec Concept wheels. Inside, the elaborate improvements continue with a re-trimmed interior that features a Dark Titanium finish with matching Cobalt Red accents, a Z-Spec sport pedal kit, an aluminum sport shift knob, and a dressed up flat-bottom steering wheel with a Cobalt Red suede trim.

Under its hood, the Sonic Z-Spec 4D Concept will carry performance modifications on its 1.4-liter turbocharged inline 4-cylinder engine, as well as a new suspension, brakes, and exhaust system. The standard model’s output is 138 horsepower, but you can expect that to increase with these mods.

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read full bio

Wow, another good-looking Sonic concept vehicle! I have to agree with them that this 4D look so awesome on its sleek body paint and on its aesthetic design. Good thing as well that they use a turbocharged engine on it.

I thought the Chevrolet is really focusing on producing a muscled car. smiley Well, I must say that they are truly so awesome when it comes into a good-looking car and giving a nice engine specification, just like on this concept of them.

It looks so classy and sophisticated on its sleek black body paint, and I noticed that its wheel is absolutely looking very cool on it. I just only hope that on the next updated news about it, they also include some pictures of its interior.
