The mid engine Corvette will not debut next month at the 2019 North American International Auto Show in Detroit. That much you probably already know. But what you probably don’t know is why.

According to sources familiar with the matter speaking to GM Authority on the basis of anonymity, engineers have uncovered a major electrical issue with the future Corvette during the development process. From what we gather, the vehicle’s electrical system can’t carry the load necessary to support the necessary components.

To address the issue, engineers will need to re-engineer the vehicle’s electrical system. Naturally, changes made to the sports car will also need to be coordinated with suppliers involved in providing GM with the electrical components, as well as any associated equipment. The undertaking will delay the mid-engine Corvette project by six months.

Despite this, GM/Chevrolet should still be able to launch the mid engine Corvette for the 2020 model year, though a 2021 model year launch is not entirely off the table.
