Don Sherman has been in the Car Rag business for a VERY long time. His connections and sources are much deeper than he dares report in print. However, he made an appearance on 'Autoline After Hours' TV show recently and shared some VERY Inside information. He told of 3 challenging issues that surfaced during the C8 development:
- All GM products are shifting to a new electrical architecture—the means by which 100 or more computer modules per vehicle communicate on what’s called a CAN (computer area network) bus. Engineers are having difficulty working the bugs out of the new Global B party line serving Corvette and several other new models.
- A structural distortion of the aluminum spaceframe experienced during testing a prototype equipped with the 900-1000 horsepower twin-turbo V-8. The twist in back was enough to fracture the glass hatch covering the engine.
- Some unspecified disagreement between those who design Corvettes and the development engineers who push them to the far corners of the performance envelope. It could be a visibility issue, some ergonomic shortcoming, or a cockpit design issue.
The ZORA model (which we call the highest performance variant of the C8) includes a combination of electric motors with a twin-turbo V8 to make 900-1,000 hp and apparently the massive torque was causing the twisting of a frame member and cracking the glass engine cover. ...the frame issue was solved long ago with the help of GM’s Cray Supercomputer which analyzed the frame structure and identified the areas that needed reinforcement. GM’s plans are to use just one chassis for all C8 models so now the base “Stingray” model will have the same reinforcements as the ZORA model.
We do think that the recent sightings of the car with Mark Reuss in Yuma, along with Tadge, Harlan and Alex in San Diego lead us to believe whatever issue 3 was has been resolved by now as well. You don’t fly the GM President half-way across the country to ride in a car with issues, you fly him out there to ride in a car in which the issues have already been fixed.
...the timing and location of the C8’s reveal by suggesting the NCM’s 25th Anniversary Show in late August as his best guess on where and when the car will be revealed.
