In Stockholm and LA it was just the BioPower 100, a 100% ethanol fueled hybrid. A premature press release identified it as a plug-in, but that was withdrawn and the plug was not to be found. It had, perhaps, been glued shut.
Now that the Volt has premiered in Detroit to huzzahs and widespread press, this Saab, yet another GM concept hybrid, has been unveiled, again. Although Plenty magazine identifies it as a plug-in, nothing in the press material I found confirms this. It does have a switch to run on lithium battery electric power for up to 20 km, but a plug does not appear to be part of the equation. Since 100% ethanol is hardly available, this must be considered truly a concept car. With a plug and a flex-fuel E85 capable engine, they'd really have something marketable. Don't hold your breath.
