The move is in response to a number of vocal owners who experienced overheating issues when pushing their cars hard in hot weather. According to Motor1, Corvette chief engineer Tadge Juechter said the issue only afflicted about five percent of owners, but they were a very, very vocal five percent. So as part of his team's "continual improvement," Juechter's team set about developing a solution.
While Chevy will apply the changes to all 2017 Z06s when production resumes this fall, we're still waiting on details for current owners. "We intend to have the new hardware as a relatively straight forward retrofit to existing cars. We'll announce timing and pricing as we get closer to the restart of Z06 production. So look for an update from us in the coming months." Juechter told Autoblog in an emailed comment. "Again, these changes are designed to improve the cooling performance on track in high temperatures. The engine will carry over its SAE 650 horsepower and torque ratings."
