The plot thickens even more as Tadge Juechter provides a fairy tale regarding 2015 Corvette C7 Z06 disaster during Motor Trend's Best Driver's Car comparisson

If the plot was not thick enough already in the aftermath of a true disaster the newest +General Motors flagship, Corvette C7 Z06, it just got considerably thicker, with +Tadge Juechter aka Titanic chief engineer, telling another fairy tale, excusing its failed creation. 

To Tadge's credit, he never fails to perform while telling those bullshit stories, unlike his creation or his engineering skills.

So straight from the horse's ass:

we check our press cars before we send them out. However, you are probably looking for the full story and how to reconcile how a Z06, actually the exact same Z06, could do so well in Car and Driver's hands for the Lightning Lap and be such a disappointment weeks later in Motor Trend's Best Driver's car issue. First a little background: Corvettes are highly sought after test cars for media around the world. The number of requests we get to evaluate cars is well beyond our ability to accommodate them. We have to pick and choose and set priorities. The natural question might be: "You are the manufacturer. Why don't you just make more cars and have a bigger press fleet?" The truth is we have limited resources to manage such fleets and since we are capacity-constrained in production at Bowling Green, every car we put into the press fleet is a car we take away from a paying customer. That means people who have had orders placed for a long time have to wait even longer. We try to accommodate as many media requests as we can and that means there is enormous pressure to minimize the prep time for cars between media loans. Media deadlines are absolute, just like race start times, if you aren't ready when the green flag drops, you don't run. The goal for media prep is always the same: Make the car like-new for each loan. Sometimes this is easy, sometimes there is a lot of work to be done. Magazines and other media rightly expect the cars to be perfect, both mechanically and aesthetically. They usually use the same car for photography and track testing. It would be great to send two cars for every loan, so we would have a back-up, but then we would have to double the size of our fleet (see above). Bottom line is that the Car and Driver loan and Motor Trend loan were scheduled back to back. What could go wrong, right?

A lot, as it turns out. During testing at C and D the car went off track into a tire wall. Stuff happens. It wasn't the first time this has happened and I'm certain it won't be the last. Fortunately, the damage to the car was cosmetic (rear fascia, supports and the energy absorption assembly). It didn't have any fundamental structural or chassis damage. The alignment was fine. Basically, zip ties and some duct tape was all it took to make it track-worthy. The car then went out and ran the second fastest Lightening Lap they have ever recorded.
Any time there is an incident like that, we have to tear the car down, replace broken parts and make it like-new again. In the few days we had to prep the car for Motor Trend, we did a tremendous amount of work to make sure the car was safe, capable and pretty. In our haste, two things were missed. We always replace brake pads before delivering a car, but this was missed. I can’t remember this ever happening before, but it did. We have since changed our pre-test check procedure so this can never happen again. Although Motor Trend made it a point in the article, they did not notice any issue with braking performance during their spirited street drives. Our engineer on-site noticed the linings were worn, and they were immediately replaced and burnished. This was done the day before the Z06 was run on track by Randy Pobst and had absolutely no bearing on the results of the test.

The second unfortunate occurrence related to the intercooler circuit. One of our pre-loan checks is to bleed the intercooler circuit to make sure there is no air in it. Some customer complaints about over heating Z06s have been traced to improperly bled intercoolers. The technician doing the work plugged in the electrical connector for the intercooler pump and it seemed to seat and "click" into position, but the secondary latching mechanism did not fully lock into position leading to intermittent operation. Without the pump running there is no coolant flow, no intake charge cooling and the engine pulls spark to protect itself. That is what Motor Trend experienced at random times during their testing. Unfortunately, the connector was seated enough that the pump and engine worked fine in all the pre-test driving done before trucking the car across the country to Motor Trend in California. Remember this is the same car that performed flawlessly a few weeks prior in sweltering heat during Car and Driver's Lightning Lap. The possibility of bad fuel was discussed because it was clear there was an abundant amount of spark retard, but we didn't discover the true root cause until the car had returned to the Milford Proving Grounds after the test. We have modified our procedure to run the pump remotely during the bleed process so this issue can be avoided in the future.

Bottom line is that like any team we have good days and we have bad days. We showed well at Car and Driver Lightning Lap and stumbled at Motor Trend. We engineers and technicians on the team are even more disappointed than any in the Corvette community. We are reviewing our prep processes, which loans we prioritize and even the size of our media fleet. We will get better. We will live to fight another day. Motor Trend is planning another test at Laguna Seca in a few months with some very, very capable competitors. We intend to be ready.

For the purpose of entertainment, some interesting and outright funny statements were highlighted.

First of all Tadge,  are you out of your fucking mind claiming there is a shortage of these CERTIFIED SUPERCARS?  There is a shitload of these disasters sitting UNSOLD and growing number of USED ones literally dumped at will by formerly happy owners.  If there was a bullshit excuse of the year, this has to be it, better than those defective oil filter.  Really Tadge, Billy Mays found a great successor.  You practice this bullshit on your family before spouting off in public?

Secondly, make up your mind Tadge, a superficial damage to the car determined how exactly at the track to allow for those zip ties Tadge?  And why bother with that complete tear down afterwards if the damage was strictly superficial?  Did you just eyeball the frame and suspension components and then used those zip ties and duct tape?  Did the driver get personal OK from you to go back to the track?  Again, why the tear down after that superficial damage?

Here is the real good one, with that supercharger pump partially plugged in, the problem here is that the pump provides a direct feedback, setting off onboard diagnostic and generating a code, this is why that feedback is included in the pump circuit, not any different than with the ZR1.  And why on Earth would you unplug the pump to run it remotely?  Just like with ZR1, this part is handled by diagnostic Tech scanner.  Has this changed recently and paperclip is used instead?  Come on Tadge, this is outright bullshit.

And that air bubble, LOL at that one.  You do understand that bleeding this system is not likely, righ?  The expansion tank is below the intercooler, making the whole bleeding procedure rather difficult and while the system is filled under vacuum, the pump is made to run so why would you be unplugging the pump at all?  Oh and that air, the way the system works, certain amount of air is necessary, due to EXPANSION of coolant, expansion tank-get it?  Are you suggesting the test car was set up not to have any air in it at all?  WOW, thanks again more comedy Tadge. 

Why not just suck it up and admit you failed designing this piece of shit, certainly much more therapeutic than coming up with these bullshit stories, lying is hard work.  Man up and quit.
