Then why are you public enemy number one in the EV thread?

I wonder if it was possible to give the front motor higher gearing, maybe with a freewheel for the rear motor for top speed run.

What I find interesting on the videos is the reduced top speed at the latter half of the run. In the first high speed section ID.R reaches 270 KM/h but on the final straight it only manages 249 km/h. Could it only have the power for 250-270 km/h top speed and head wind reduces the top speed? Or maybe the motors and batteries heat up reducing the power output?

I just find it funny that of the two tools VW group is using to reset lap records, one was designed for flawless reliability at 24 hours of race pace and pretty much just has some rules mandated limiters removed to go take lap records... and the electric one generally can only muster about one lap or hillclimb run.

Like yes, the ID-R is pretty neat, but it's telling that a major automotive company's best shot is so short of another car that's just something they had laying around.

... yes that's kind of specifically my point. You have 20km of battery capacity on this thing and it does 6m-ish at the ring. The 80s vintage prototype 956 with about the same pace would do about 200km between stops. Neither was built to the bleeding edge - I mean, they sold 956s to customers. I could take my credit card and buy club race grade prototype cars with about the same pace.

I just find the whole thing a bit depressing, the more I'm doing the math.

Tires have come along massively - modern 200TW street tires are probably roughly equivalent to 80s slicks. Downforce generation has come along massively - in the 80s they were basically inventing underbody based downforce and nowadays it's proven out enough you can best-guess shapes and get pretty close, much less what happens if you use any CFD. Shock absorbers, dampers, brakes, computer controls, chassis structures...

When they took the 919 out (which was not intended as a one lap wonder) it beat the 80s lap record by 50 seconds. VW group had all of that data handy; the ID-R should be able to be that much more extreme because it doesn't have any of the compromises necessary to do more than 20km on a charge, nor was it ever built to any rules. And yet...

Do you care enough to read a wall of analysis text if I write it? Because I'm pretty sure I don't care enough to write one.

Short version is the Nurburgring is annoying to compare times to because the VLN stuff uses a different course configuration and mostly the only people who bother with the same configuration VW ran are people dickwaving production car lap times, which are always going to be pretty feeble compared to actual race cars. But it's easy to compare Bellof's old 956 lap record because they ran 962/956s everywhere back in the day.


That's fine, but the 919 Hybrid actually had to compete under these things called "rules". Meanwhile, at something close to sea level, I'd wager an M20 with a good driver, in plain CN spec (not exotic 'strap horsepower to it' pikes peak variants) would be right around a 6 minute lap of the 'ring too.

That's nice. Why'd it only turn a 6:05 lap then?

Beautiful cars, the Voisins. I've seen one in the flesh, at the Tampa Bay Automobile Museum. They have a partly leather-bodied Voisin along with a bunch of odd-ball poo poo. As my father and I were oggling a one-off French micro-car my eyes wandered over to the Tatra truck next to me, which just so happens to have a Kegresse track system installed. Two things I never thought I'd see, right next to each other! Lots of early FWD cars, to include what is left of an experimental FWD Formula car from the '30s. Every V8 Tatra car minus the 700. The only factory 4wd Mustang. An early Aston Lagonda V8, a well used Citroen SM, VW Schwimmwagen, a 4wd German Ford cop car, and, and, and... loving place is awesome. Weird cars, on-site staff who can and will tell you everything about the vehicles you are looking at, plus all the cars except for the Ruxton get driven on the road. Anyways.

I hadn’t thought about mechanical injection would actually need to do to map fuel (or much about mechanical injection all if I’m honest), that’s really cool. Doesn’t ferrari (are there others? there probably are, I honestly don’t know) use a 3d cam profile for an [effectively] infinitely adjustable vetch style variable lift? Seems like a huge ask for cam bearings to have the shaft slide axially through them.


Growing up 15 miles from Watkins glen has put an amazing assortment of old and rare cars in front of my eyes, I have to say that it’s only in the last half dozen years or so, since I’ve been working at a place with access to a machine shop, that I’ve given pre-war stuff more than a cursory glance. I get it now- just looking at a machine of that era through the lens of this era, you can pick up the decisions and see how ‘let’s throw this at the wall and see what sticks’ automobile engineering was then compared to now.

I love stories like that, and there’s an awesome thread (engineering anecdotes) there, but stories/anecdotes like never really seem to come up without some prompting.

They're water cooled and probably don't run much hotter than consumer engines. F1 cars are fast because they're light and small.

So, I don't have a source for this that's not , but for anyone who likes goofy engine designs, look for a book called "Some Unusual Engines" by an author with the last name of Setright.

It was written in 1975 and has been out of print for I don't know how long, but it's full of interesting and oddball internal-combustion engine designs that were tried over the years. I was talking to some coworkers today about goofy designs. In the past I found where some dude uploaded it to his website, but if you ever find a copy, check it out.

I'd lean more towards the latter, but wouldn't be surprised at all at people not knowing about an English author who did most of his work half a century ago.

Don't forget about the Dauer 962, the other street version of the 962! This was my childhood dream car.



I love the fact that more than one company looked at the 962 and decided that it needed to be a streetable road car.

The only time I've ever used the handbrake while driving in my 10 years of driving manual is when setting off in steep hills. There is 0 need otherwise. I've never understood the hysteria in the UK of applying the handbrake at every drat light. Just makes me cringe.
