For a factory driver lap time, this isn't very impressive I'm afraid. Just good average I'd say...in this class.

I would say it is a good lap time...remember this is not a Z06 or a ZR1.

It is only 3 seconds faster than the C7 Z51 which is not much improvement over several years and a totally new Mid-engine platform...

Agree.  The basic platform should address the performance issue of the old platform yet the results don't reflect any tangible improvement.
