The skunkworks over at Chevrolet are polishing the final details of what is set to become the swansong of the C7-generation Corvette. We are talking about the all-new ZR1 which has been spotted near production form, entering Milford Proving Grounds.
The biggest question revolving around the upcoming supercar has to do with the contents of its engine compartment. Rumors about the core of the upcoming ZR1 are divided. One camp suggests that the LT4 V8 which powers the Corvette Z06 and the Camaro ZL1 may be used in the ZR1 with the newcomer receiving a larger supercharger. Others talk about the all-new LT5 DOHC V8 which has been confirmed for the 2018 Corvette, as being the engine of the ZR1.
For one thing, GM has affirmed that they will be considering the 6.2-litre LT5 powering the 2018 model year Corvette. However, since we are most likely looking at a naturally aspirated mill, this seems more suitable to the mid-engined C8 Corvette. This theory is not without its questions though, and that's because the engine will land for the 2018 model year, while the C8 is expected to be introduced as a 2019 model. Regardless of the engine, the 2018 ZR1 should feature the new 10-speed automatic that GM and Ford have developed together.
