With the cancellation of the Chevy Cobalt SS Supercharged (above) for 2008 and the impending arrival of the turbocharged HHR SS, speculation was rampant that GM planned to take that 2.0L turbocharged, direct-injected Ecotec and drop it in the Cobalt's engine bay. As has been shown in the past, automakers can try to keep things under wraps, but their fans find ways of digging up info, especially when that info is squirreled away on the web, and GM Inside News has organized everything neatly for us.
First up at cobaltss.net is a copy of the SAE Power Certification for a 2008.5 Chevy Cobalt powered by GM's L850 LNF engine. This is the same motor used in the Saturn Sky Red Line, Pontiac Solstice GXP, and the aforementioned Chevy HHR SS. Also via cobaltss.net, we get a link to an official GM Planned Emission Certification doc that also lists a Cobalt with the 2.0L LNF engine (the planned certification is BIN5/LEV2, by the way). So, that's it. The writing on the wall says that a Turbo Cobalt is coming. And while we don't have anything to add, you might want to mosey back here very early Sunday morning. You know, in case anything new comes up.
