The development work on the 2014 C7 Stingray is an ongoing process, and even though customer cars are on the streets, GM is still hard at work refining an already epic car. Case in point – these photos of an instrumented and camo’ed C7 spotted outside Oklahoma City by LSXMag fan Michael Morris.

“When I first saw it I was really hoping it was a Z06 in test camo,” Morris recalls. “When I got closer I noticed the body work looked too narrow to be that.”

The car wears the same round LED tail lights we saw on the burqa-clad test Corvettes running around last year before the car was released to the public, meaning that it’s probably from that same group of mules. The plate doesn’t match any of the ones we’ve seen in published “spy” photos, though. A glimpse in back reveals that this car is heavily instrumented – a separate deep cycle battery powers a stack of datalogging equipment under the rear glass.

“The trunk shot was taken through the glass – no one opened it or anything,” Morris points out. “People I’ve showed them to all ask if someone opened the trunk for me. I don’t want to get anyone in trouble or anything. I just snapped some pics and took off.”

The transporter was loaded with a mix of different GM vehicles – per Morris, “There was a new generation Sierra Denali, that caught my eye initially, that lead to seeing the Vette. There was a couple of Cruzes as well as a Cadillac. I don’t recall what the other two were. I was heavily distracted by the Vette. The Denali and the Vette both had manufacturer tags. One of the Cruzes (on bottom) had a Canadian plate but I don’t know if it was a manufacturer’s plate. When I passed the driver I gave him a thumbs up and he smiled big and waved back. Almost like he’s been getting that a lot…”

Whether this Corvette is still part of the test fleet actively gathering data, or if this transporter ride is taking it home to the anonymous fate of test cars that have served their purpose, we can’t say. Keep your eyes open, and you never know what you might see on the road…
