Good news: it looks like Hyundai is planning an actual production plug-in sports sedan, and it's basing it on the stunning BLUE-WILL concept from earlier this year, according to AutoblogGreen.

That concept's parallel hybrid system consisted of a 1.6-liter direct injection gasoline motor, a 100 kilowatt electric motor, a continuously variable transmission, and a lithium ion polymer battery pack--expect something similar in the production car.

The report said that the new Hyundai plug-in will debut in 2012 and compete with the Chevy Volt and the upcoming plug-in version of Toyota's Prius. That's not exactly a direct comparison, considering the latter two will be in wildly different price classes. But the electric car market is still too thin to break down all that closely. Either way, things are heating up.
