Interesting link. Thanks for posting Barry.
For balance, I would like to add this link, where Jim Mero clarifies some of the things he has been saying:
Jim Mero Clarifies Statements On 2020 Mid Engine Corvette C8
To be honest, it sounds to me like he was not the man for the job to lead the vehicle dynamics for a mid-rear-engined C8. He retired in September of last year.
Perhaps there are some absolutely amazing dynamics guys out there, that will be expert drivers, making you or I look like complete novices, but they may only be expert at what they know with the existing FR architecture. Maybe they needed fresh blood to deliver the best mid-rear experience for the customer, and in particular that new customer that they are going after, with the new model.
I noticed in my link and yours, they did not test versus Ferrari 488 or McLaren 570S. These cars really are exceptional on track. The Audi R8 is deeply impressive too, but I'm betting Jims comments regarding understeer pertain to the Quattro model. He should really try a 488/Pista/F8 or any of the McLarens - he might be impressed. He may also be eating his hat when the real road test reports for the C8 are released, and comparison with the Ferraris and McLarens begin. Myself, I can't wait for this.
