GM has already denied rumors about a future mid-engined Corvette, but Jalopnik has some spy pictures of a very strange looking sports car. This spied Corvette features an extended wheelbase Corvette with modified bodywork and a lot of space behind the front seats.

We do not know for sure, but considering the manufacturer plates, we presume this is a testing mule of the future generation Corvette C7.

The guy who caught this car testing said: "It's a hybrid mule, it has narrow width front tires, extended body to accommodate the drivetrain (Corvette has a rear transmission), and, interestingly, a plug outlet cover on the ass of it? The front wheels also do not match the rear wheels. Just my thought.... since GM mentioned a hybrid Corvette sounds possible."

The future C7 will go into production in April of 2012 and will then go on sale for the 2013 model year. As previously reported, its exterior design will be inspired by the Stingray concept.

Update: Some readers have pointed out that the manufacturer plate on this vehicle is not from Michigan, as all GM test vehicles usually are. It seems the California manufacturer plate 44699 belongs to Fisker->ke1074. This should be enough to put GM out of the equation and assign this car to the Fisker company. That also explains the rear plug, as Fisker is primarily focusing on electric cars.
