|It’s not any ordinary Chevy that boasts a boost gauge in the A-pillar from the factory, but the Cobalt SS is no ordinary Chevrolet. GM has turned to turbocharging to counter the import competition before, and all the previous lessons learned with forced induction are on display in the Cobalt’s innovative “LNF” engine, which features not only a twin-scrolling turbo and sodium-filled exhaust valves, but also direct injection for ultra-precise control over fuel metering. For the driver, all that technology means that the power comes on early and hard, with little turbo lag and instant response at nearly any engine speed—in fact, maximum torque is available at just 2,000 RPM. In total, the Cobalt SS commands 260 horsepower and an equal amount of torque, which would certainly overpower the Cobalt’s platform if it wasn’t for a host of suspension (and more importantly) tire upgrades. Wider and larger rubber joins forces with a limited-slip differential to keep the boosted twist from unhinging the Cobalt. The exterior also wears just enough extra bits and pieces to keep it from being mistaken for anything other than a go-fast version of the coupe, but without being overkill, and the stock alloy wheels fill up the arches nicely. American manufacturers haven’t always nailed small, sporty cars, but the Cobalt is a true competitor to the best from Japan and Europe.|
