    Default Corvette's Explanation for Mechanical Issues Motor Trend's "Best Driver's Car" Compa

    For those that did not see this issue, the "vette" was sidelined and the AMG GTS won.

    Actually Corvette Z06 is living up to its status as supercar. It will fail and embarrass you just like a Ferrari.

    I drove a few laps in a c7 z06 at BW last time out with SV. Drove an out lap and one full lap in traffic and started getting a feel for the car and its really impressive lateral grip. Passed a couple miatas and was ready to put a lap down. BAM! No power. Couldnt even stay ahead of the miatas for a lap. And the brakes got really soft even with the ceramics. Like almost to the floor soft. When I went out at first trying to modulate 650lb of torque still felt like getting punched in the kidneys. After limp mode it felt like 100lbs. Brand new car. A few thousand miles and no track time. Probably wasnt caused by some plug being loose.

    When they work right they are wickedly fast. Here is Andrew Aquilante in a bone stock Z06 hitting 151 MPH at NJMP and within about four seconds of his SCCA Runoffs winning GT2 race car.

    It was also the fastest car the Car and Driver "Lightning Lap" camparo at VIR - in 100 degree heat

    Z06 = 2:44.6 ($100,245)

    MacLaren 650 S = 2:45.8 ($353,115)

    Lamborghini Huracan LP610-4 = 2:47.5 ($274,720)

    Porsche GT3 = 2:50.4 $(162,010)

    Mercedes AMG = 2:51.0 ($171,900)

    Previously, GM's test driver drove a 2:41 - in stock trim, but perfect conditions.

    The C5Z06 when raced needed a larger radiator, Diff and Trans coolers. Perhaps the 2015 Z06 just needs us in the aftermarket to fix it. It was the aftermarket that blew up motors did GM's research and development and came up with the Avid Drysump for the LS3 motors. Why should this situation with the new Z backing out timing when hot be any different? Maybe all it needs is a bigger radiator...Ron Davis to the rescue, and a giant intercooler.

    It doesn't seem like it was a heat issue. The car also ran crappy the prior day in the "highway" session, and the Cadillac CTV-S with essentially the same blown motor ran like a champ.
