not drastic; 17‑inch broad spoke wheels with narrower P205/50R17 all‑season Pirelli tires were standard, as was the low profile spoiler. 2.4 L and 2.2 L Sport Package Cobalts have a 140 mph (220 km/h in Canada) speedometer with optional white face gauges. The car rides on the FE3 suspension, superior and more sport‑tuned to that of base Cobalts but less refined than the FE5 on the supercharged and turbocharged cars. Brakes on the 2.4 L naturally aspirated and supercharged model are identical, but the turbocharged model received an upgraded Brembo braking system. The front and rear bumpers are the same, but the front lacks a lip accessory and the bottom of the rear fascia is slightly different. With the exception of exterior styling and some interior trims, the vehicle is identical to the Pontiac G5 GT. Reception Reviews of the supercharged Cobalt SS were generally positive.

It's almost like it cut everything in half." In his review of a later model, John Neff of Autoblog called the wing "obnoxious". Some Cobalt SS owners have traded spoilers with lower trim owners to obtain a less aggressive look, or traded the entire trunklid with Cobalt LS owners, for whom a rear spoiler is merely optional. The naturally aspirated Cobalt SS has been seen as an improvement over the base models with its slightly more potent 2.4 L engine, but notably inferior to the supercharged car. The powertrain of the 2008 turbocharged Cobalt SS received rave reviews. John Neff of Autoblog said, "The GM Performance Division completely reworked the Cobalt SS for 2008, swapping in
