According to the post, the car is being referred to internally at GM (NYSE:GM) as the "HP Edition." Which, we presume, means "high performance edition."
Other news include a 6.2-liter supercharged V-8, a magnetically-controlled suspension, 285-millimeter tires in the front and 330-millimeter tires in the rear, a hood with louvres, and slight interior upgrades.
An early January production date means that the car will likely go on-sale shortly thereafter. We'll keep you posted.
