Chevrolet Impala Blackout Concept in detail

As suggested by the name, the Blackout Concept takes the classy and slightly aggressive cues of the standard Impala and adds a dash of soberness by means of blacked-out exterior parts. Finished in the standard shade of black available with the 2015 model, the sedan received matching grille surround, rear spoiler, mirror caps, and bowtie emblems, all sourced from the Chevrolet Accessories catalog. Rounding off the exterior is a set of 19-inch, five-spoke wheels finished in black and polished aluminum. Chevy describes the Blackout Concept as an Impala with a "sinister attitude," but that's nothing but lip service. That's not to say the upgrades don't add to the Impala's appeal, but the sedan is rather a more serious proposition than a "sinister" one.

Moving into the cabin, Chevrolet added an all-black, leather-trimmed interior, custom trim plates with a wire-mesh pattern, Chevrolet Accessories stainless-steel door sills and a sport pedal kit. The concept also borrows the production car's optional 11-speaker, Bose Centerpoint sound system.

Under the hood of the Impala Blackout lurks the nameplate's range-topping 3.6-liter, V-6 engine. One of three units motivating the Impala, the six-banger cranks out 305 horsepower and 264 pound-feet of torque.
