If a car company played a major role in the creation of the rules we should be honest and mention it. Drachentötbär (talk) 01:38, 25 November 2022 (UTC)Reply

That was covered when they made some suggestions and is noted at the top of the talk page - their edits were independently checked and agreed at the time. NealeWellington (talk) 00:50, 17 June 2023 (UTC)Reply

Dauer 962 LM has VIN and WMI by Dauer.

edit

We have confirmed VINs TP99620133, TP99620141, TP99620151, TP99620172, TP99620175.

The VINs with WMI TP9 are not not from Porsche so they must be from Dauer. Drachentötbär (talk) 00:06, 11 June 2023 (UTC)Reply

TP numbers are from the Czech Republic - this article 1993 DAUER 962 LE MANS PROTOTYPE ROAD CAR points to these cars being prototypes so if that is the case then they are ineligible. Nice cars though. NealeWellington (talk) 03:08, 11 June 2023 (UTC)Reply
The cars using those VINs were sold to Brunei, they weren't prototypes. Dauer was located in Nuremberg, which is quite close to Czechia, which might explain the Czech VIN. Both the TP and the 9 for small manufacturers don't fit to Porsche. Drachentötbär (talk) 18:46, 11 June 2023 (UTC)Reply
The article is quite clear in stating that the car setting the speed record was a prototype which automatically excludes it from this list unfortunately.NealeWellington (talk) 23:40, 11 June 2023 (UTC)Reply
The article states "it is believed that this prototype car was the one that was used for the speed record ... but we are still chasing down photos and details of this speed record attempt to confirm these details."
Tests of prototypes with the same specification as the production car are allowed on this list (the McLaren F1 entry is based on the XP5 prototype), so if there are no significant changes which affect top speed it should qualify. Drachentötbär (talk) 19:26, 14 June 2023 (UTC)Reply
It looks like the Dauer's had no consistent specification, as the article notes differences in bodies and transmissions. What we need to try to establish is whether on matched the prototype. I'll keep searching but the information looks pretty scarce. NealeWellington (talk) 00:08, 15 June 2023 (UTC)Reply
It's sufficient if the same specs were available for buying. The body differences found in article don't affect aerodynamics significantly and it wouldn't make sense for Dauer not to offer the record car gearing to customers. Drachentötbär (talk) 22:19, 16 June 2023 (UTC)Reply

Mclaren F1 vs Dauer 962LM

edit

The fact that the Dauer 962 is on the list does not exclude the Mclaren F1, as the Mclaren's 355 kph record was broken much earlier. Eduardo César Schmidt (talk) 18:14, 3 November 2023 (UTC)Reply

At Mclaren F1 it says the 355 km/h speed in 1994 was by the magazine Car and Driver. The reference link is no longer valid, so I cannot verify any details. Specifically, was it in road trim (eg no special tyres, no modifications, no removal of weight), was it an averaged 2-way run, and was it recorded by an official body.  Stepho  talk  23:18, 3 November 2023 (UTC)Reply
So it should be on the list. Eduardo César Schmidt (talk) 21:31, 1 January 2024 (UTC)Reply
Not without references from reliable sources. See WP:FACT and WP:RS. We need supporting references for the speed and also that it was an unmodified car (stock tyres, no weight removal, etc), was it a 2-way run, was it recorded by an official body (not by the manufacturer), etc.  Stepho  talk  21:44, 1 January 2024 (UTC)Reply
What about F1’s two-way run in March 1998? The Element 911 (talk) 19:07, 24 February 2024 (UTC)Reply
Do you mean Andy Wallace's run in the XP5 prototype? Prototypes are not production cars unless you have a reference that it is substantially the same as the production version. There is the usual grey area about what changes are permissible - eg changing body colour and interior trim is fine but changes to shape, weight, engine, gearing, tyres, suspension, etc are not.  Stepho  talk  01:47, 25 February 2024 (UTC)Reply
Take a look at Talk:Production car speed record/Archive 7#McLaren F1. The test car was a prototype and not the production car. NealeWellington (talk) 04:58, 3 January 2024 (UTC)Reply

Dauer 962 Le Mans: does it still deserve to be in the list?

edit

The 962LM has been a large topic of discussion for this page for some time, and so I wan't to question again whether it still deserves to be in the list, and I have a few reasons on why it shouldn't.

First of all, if we take into account the "notes for editors" topic, it should've been already excluded, for having "not enough built". Out of the 13 cars allegedly produced (a claim mentioned in multiple articles), we can confirm the existence of most of them: 1 is the original prototype displayed at the 1993 Frankfurt Auto Show, 5 road cars were built for the Sultan of Brunei, 1 is the homologation special "GT-style", 3 are the race cars built for the 1994 24 hours of Le Mans and 1 more was built and sold in 2001. If we assume that the first prototype was the car to claim the record, then only 6 out of the 11 cars mentioned could be on the same spec as the one that hit 404,6 km/h; the final model built had a different gearbox, the GT-style 962 features significant changes on the bodywork and the 3 race cars aren't road legal. So that leaves us with only 6 cars that could have the same specifications of the possible record beating car, so does a car with these few made still qualify as a "production car"? Moreover, we are not sure if the 5 cars delivered to Brunei have the same drivetrains as the first one.

The record run is also heavily undocumented, with little to back it up, other than AUTO BILD's and EVO Magazine's articles and Dauer themselves. We don't know who did it, what car was used, if the car was modified, if they were following the criteria used for the rest of this list; hell, we don't even know if it even happened.

I'm really feel like it doesn't deserve to be here, but I don't think it is fair that I just outright remove it based purely on my opinion. Arambojubr (talk) 07:12, 10 August 2024 (UTC)Reply

Yeah. I was wavering a bit on that too. Thanks for the new reference https://dempseymotorsports.com/1993-dauer-962-le-mans-prototype-road-car/ that provides many more details.
From what I can gather, it is a fully road legal car with it's own VIN (TP9962...), so it obeys all the rules for our list. We removed the quantity made requirement a few years ago, so it should be fine to keep it.  Stepho  talk  08:55, 10 August 2024 (UTC)Reply
With that in mind, it makes more sense, but I still stand by my argument. We don't know the specs of the 5 cars owned by the Sultan of Brunei and the details of the record run. The fact that so little is publicly known about this car makes it a challenge to tell anything about it. I'm also a bit mixed with the lack of a requirement of minimum units produced, but since this has been decided such a long time ago, I won't argue. Arambojubr (talk) 12:12, 10 August 2024 (UTC)Reply
