...Our suspicion is that Nissan got a bit greedy in its quest for today’s all-important fuel-economy numbers and boosted the Z’s aerodynamics a little too far by cutting back on the amount of air directed through the wheel wells to cool the brakes. Key takeaway: If you intend to track a Z, don’t use the base pads, upgrade the brake fluid, and be sure to install brake-cooling ducts.

 

Also, VW/Audi > *

 

Nissan’s DOT 3–grade fluid, which is used in everything except the GT-R, has a dry boiling point of 450 degrees F. That’s identical to that of GM’s DOT 3 fluid, which is used throughout most of the General’s lineup, including Corvettes, but is not as extreme as VW/Audi’s 509-degree DOT 4 fluid.

So another journalist with little to no driving talent destroys a car and immediately tries to place blame on anything he can. Couldn't be his fault, he works for Car and Driver:jerkit:

 

Anyone who plans to do more than a few laps around a road course should plan on upgrading fluid and pads no matter what they are driving or how much it cost. Brake pads up to the task of heavy track duty are miserable on the street. They make noise, kill rotors, and don't perform when cold. An auto manufacturer couldn't sell a car with pads like that.

 

Back to the journalist, Pads don't just stop working, there are many warning signs. If he is unable to detect the brakes going away he needs to stay off the track and stick to reviewing minivans. And who's to say he wasn't over working the brakes in the first place? Poor driving is the number one cause of brake fade.

Um, so someone intending to test the performance of a stock vehicle should upgrade some of the most important parts of that car, thus rendering all findings completely and totally useless? Hmm, interesting testing methods.

In their defense, it was the "Lightning Lap" test, which is only for performance cars. Up until now no car has had that type of issue (Even Cobalt's, GTI's, Genesis Coupe, etc). I'm not sure who the driver was, but for this test they usually select pro drivers. It wasn't some hack journalist at the track because there were free doughnuts for breakfast.

The car isn't designed to handle that kind of stress, therefore, testing it in that manor, you can/should expect things to go wrong.

Except in other cars, things didn't.

 

So wouldn't a pro driver be more likely to drive it like it's a race car, instead of the day-to-day drivin car it was meant to be?

 

Or since it was a pro driver you can get consistent test results. A 370z is not a day to day driving car. It is a go fast car that people will want to drive fast and hard, and this test found that it fails at that.
