Will General Motors ever release a full set of performance figures for the 2015 Corvette C7 Z06?

The hell will freeze over before this happens and thus, this was purely rhetorical question.  In order for the specifications to be released, there is one requirement that must be satisfied by a new car: these specifications must surpass the figures of the car it replaces.

As it was already well documented, +Tadge Juechter  permanently "forgot" to release the top speed of the Stingray just like he "forgot" to release performance figures for the manual version of the car or the ever popular Nurburgring lap time.

Will things change for Z06?  Absolutely not!!!  The car is over 400 pounds heavier than the predecessor and aerodynamically inferior, even without the gaudy Walmart style ground effects, thus, the top speed of the new car will never be disclosed.  In order for this to happen, this car would have to exceed the 205 mph well documented top speed of the previous ZR1 and this will just not happen due to pesky physics laws.

No performance figures will be ever released for the convertible version of the car, this is a given.

As usual, lateral acceleration will be available, after it is measured at about 65 degrees ambient temperature due to summer only tires as with the Stingray.

0-60 time, this one should be interesting...  The car has a great disadvantage against the last, manual transmission ZR1 and its 3.4 seconds.  Since the car is considerably heavier, only an automatic transmission version may have a chance, due to small converter and hopefully less inertial and friction losses.  If this happens, by some miracle, then without any doubt, the result will be advertised across the board for all Z06 cars since this is what Juechter and +General Motors did with the base Stingray.

Quarter mile speed and time should be interesting to see.  The car has enough horsepower to achieve good times and speed, in good weather and with automatic transmission but if it can surpass the last ZR1, this is yet to be seen.  Although the aerodynamics do not matter in this case, extra weight does as it does the torque management and heat soak.  If the car can manage anything, it better be at the first try or it will not happen at all.  Latest Dodge Viper already showed what torque management can do...

And finally, the Nurburgring lap time... Even the Z51 Stingray already has problems with automatic transmission overheating due to inadequate cooling system design and capacity.  Can new Z06 with automatic transmission survive a several laps on Nurburgring without overheating the transmission?  Since Juechter never admitted what happened with the base car at the ring, chances are very good the automatic version of Z06 will not be suitable there either.  GM needs a significant achievement using the new automatic transmission to validate it as a suitable equivalent of DTC, if this does not happen, then all the time Juechter spent bullshitting about it was wasted and there is no advertisement for the new transmission that is supposed to be the across the board corporate jewel.

Based on the bullshit and lack of information that continues to surround the Stingray, the new Z06 has a great chance to follow the exact same fate.  The increase in claimed horsepower already indicates that the extra weight causes negative impacts on expected performance of this porker.
