I have it on good GMAuthority that the Corvette Racing team will begin testing on the race version of the C7.R in a matter of weeks as stated in an interview at the just before the beginning of the 2013 24 Hours at Le Mans, by Program Manager for Corvette Racing, Doug Fehan.
And from the anonymous mouth of a person who is a piece of the CR Development Team, the new "C7.R's look 'phenomenal' and 'extremely aggressive', making the current C6.R look 'dated'." With that being said, I cannot even imagine how much more aggressive the new car can look without having the driver's race suit covered in blood, and a pair of hatchets affixed to the front wings used for a bit more downforce.
There is no word on whether or not the new car will continue to use the current heavily modified 5.5 liter LS7 V8 small block that cranks out 491 hp's and 604 lb.-ft.of torques, and propels the current C6.R to the top of the heap will be retained or if they have a whole new power plant in store for the new C7.R. Either way, it will be "more aggressive" somehow. I cannot wait to see the bloodied driver and the hatchet aero pieces at the beginning of the 2014 ALMS Racing Season. Hopefully we will be able to catch a few testing pics here and there.
