I dont think so.
You can hear it burble when driving slow (at least that's what I think I hear); a flat plane crank doesnt do that because it has a different firing order.

How did this happen? A lot of people might be pointing fingers at the driver, but to be honest, you’ve only got to hit pause twice to see what REALLY occurred when that lovely 2017 Camaro Z/28 plowed into the wall. To wit, I bring the jury’s attention to Exhibit A: EXHIBIT A: Chevrolet 2017 Camaro Z/28 prototype, with a locked-up rear axle. As the driver brakes hard for the slowest turn of Adenauer Forst, the rear axle locks up. This is normal for any car with an ABS failure. Why? Because when the ABS controller sh*t itself (maybe he hit a kerb too hard at the top of the Foxhole, or the wheel-speed sensor went for lunch), it also lost the ability to figure out the electronic brake distribution. And the default setting is normally rear-bias. I’ve had this happen to me in a lot of cars at the Nürburgring. From Porsches, to Renaults, Lotuses and even Fords. So the rear axle locked, the driver didn’t get much time to think, and then he did this… EXHIBIT B: A 2017 Chevrolet Camaro Z/28 prototype with four locked wheels A typical reaction, and one I could see myself doing too, he braked even more. Sure, why not? The car wasn’t stopping, and there’s nothing to say whether or not this prototype’s ABS warning light was always on, or not even fitted. So you brake more, and steer away from the fence…. Which didn’t work. Oh well, that’s why we test cars before we sell cars! |

Honestly, when I saw the title of this thread, I thought it was going to be an epic-only-occupant-zone-left crash where maybe it hit a wall and ripped the front or rear or both sides off. This was much more benign than I was originally thinking, although still serious and serious damage, but not the "totally out of control and sideways tumbling" I was expecting given the speeds this thing can reach.

Brake bias on cars is not at all rear biassed. It might be that the esp/esc system (not ABS! although it uses roughly the same components) was totally confused and started to rear brake (which is possible with esp/esc, not abs!), or maybe that this was a testcar with adjustable brake bias and something went wrong.... Or maybe a problem with the rear diff (if it has torque vectoring), who knows. But certainly not 'normal for any car with an ABS failure.' because 'the default setting is normally rear-bias'. That simply doesnt add up. Normal street cars are very front biassed, and if your abs fails, it will brake predictably as you're used to. It only wont prevent lockup which will happen first up front in 99% of the situations (just as you want to). Everyone can test this by disabeling the abs (pulling a fuse or so) Lots of people here probably have experienced that themselves. tons of e36 or e36/7 owners have had to replace their abs units (common fail), and all have lived to see the day.... But that car will be full of telemetry equipment, so they will monitor all those systems closely and adjust that fault (probably software related in one of the computers)

LOL.............
All test cars have a cover in case of incidents like that or if the car breaks down so no prying eyes (or other manufacturers) can get details from videos like this. The 'ring will even send a special covered flatbed to get the car.

They have covers with them at all times usually, even for road testing in my experience.
