The way GM timed the ZLE lap is how everyone was doing it, so the time was apples to apples.

If you think GM was lying, then they are all lying.

"The Nordschleife circuit itself, which does not include the modern Grand Prix course, is 12.9 miles (20.8 km) in length, but even that is not entirely accurate as it relates to these lap-record attempts by road cars. Most of the attempts are terminated 656 feet (200 meters) shy of a technically complete lap, coinciding with the entry and exit of the small pit lane that most manufacturers use as their staging point, marked T13 on many Nordschleife track maps. Therefore, lap times are of a 12.8-mile (20.6 km) lap, not the full length"

"Who is scrutineer of the ’Ring-running cars for technical compliance to production-car standards, as would exist in organized competition under FIA, SCCA, or IMSA?

How do we know that they retain their production street trim and tune with legitimate production-issue parts?

Lastly—and here’s where the lap times start to bend under the weight of absolute truth—who is responsible for the official timing of the lap?"

The answer is: No one.

"All the timing numbers and stats on the Nordschleife spreadsheet for a claimed “road-car lap record” must carry an asterisk with a caveat: “unofficial.”

There's a video of an interview with the ZL1's crew chief wherein he said the lap was closer to 7:13.

Thank you. Well said.

Yup. I remember that statement. Good find

They also used a A10 car and modified it to look like it was a manual.

To be honest, It's all fake and marketing stuns.
You can always accelerate the video in the editing.

Was Bimmerpost your source on this?

If you look at the video from each source it's crystal clear that the ZLE started at what many mfrs are are using as the 20.6 KM start line, and finished at the same 20.8 line that BMW used for start/finish. A quick review of videos shows this, you can choose to ignore it of you want.

I'm a ZLE track fanatic and track my 2018 HBM ZLE at least 8 days/year since 2019. I know the ZLE could do a faster lap at the Ring, with a pro driver I'd say easily a 20.8 KM 7:16 or better. An A10 ZLE could do a 7:14 or better. But we'll never know from GM, or probably anyone, you need a team and an open track.

The point is they they bragged to the world (as they should if it was true) that they did a 7:16 over 20.8 KM, and the truth is they didn't and it looks like they deliberately lied about it. Then they took down the videos for some reason. I'm disappointed in GM for this, it's a bad look.

[RobZL1]

Likely just this department vs that department, would be my guess. Marketing wrote an article, missed the little detail, then factor in the 20.6 that used to be the old standard.

I doubt there was ill-intent at the time. They probably just pulled it all down recently to prevent any noise about it. And here's the noise anyway. LOL

Surely an a10 ZLE would gain far more than 2 seconds over a manual?

Probably 3 to 4. That manual was tapped out on the long backstretch. The Auto would've kept accelerating.

I honestly don't care about this. But congrats on BMW I guess for finally building a faster car than a 7 year old Camaro though.

It’s been more than 5 years since that lap time was posted and now some BMW gurus have debunked that video? Lol. Sounds to me like some BMW owners are butthurt an American V8 can still beat their overpriced lawnmower sounding car. Remember what Lincoln said … don’t believe everything you read on the internet

A bad look?! Seriously? That’s a big reach my guy. The video was up for years. YEARS!!!!!

Probably a minor oversight. The fact that an American Mechanical Engineer that just happens to develop the Camaro set that time in Europe speaks volumes about the car. At some point, we really gotta read in between the lines.

That’s not really true. The aero limited it’s top speed by nearly 10mph. The 6th gear in the ZL1 is actually useful and is not an overdrive gear.
