We may not be getting a Spark SS any time soon or at all but the Sonic SS is the closest we can get to one....
Chevy Sonic SS Rumored as Fiesta ST Rival | AutoGuide.com News
The RS package for the Chevrolet Sonic delivers handling and styling upgrades, but doesn’t help in the power department, as the Sonic RS still utilizes the same 1.4-liter turbo engine making 138 hp. But that may soon change.
According to sources at GM Inside News, a new Opel-built 1.6-liter turbo four cylinder will likely find it’s way under the hood of the Sonic, giving it some legitimate hot hatch credibility. The engine could make as much as 200 hp and 221 lb-ft of torque, taking the fight directly to Ford’s Fiesta ST (recently confirmed for the US), which makes 180-hp and 177 lb-ft of torque. An upcoming seven speed dual-clutch transmission, designed specifically for small FWD engines, could translate the power in the Sonic SS.
RS spec Sonics receive MacPherson strut front suspension, coil springs, a stabilizer bar as well as a semi-independent rear suspension, with gas-charged shocks. Look for these upgrades to come on the Sonic SS as well.
Though it may or may not wear an SS badge, if it does come to fruition, it would be the most powerful sub-compact hot-hatch on the American market, making it worthy of the SS moniker.
