Pikes peak is a TT. It's racing against a record not so much competition. That goes for everyone. But I'm sure we'll get some news about the runners soon.

It's technically competing in unlimited class with some liquid fuel cars. If WV beat the EV record by a lot they might win overall as well.

Is this a child of the 919?

No, it's based on a Norma, the same one that Romain Dumas tackled Pikes Peak before. They have just placed some attractive bodywork on it and stuffed some batteries in there to make it heavier ;)

Do you know it's a norma-based chassis or are you guessing?

Here’s from Autocar.

The chassis is built around the safety monocoque from a Norma sports prototype that Dumas has used to win Pikes Peak for the past three years, with VW developing a closed-cockpit sports prototype-style design.

How does this compare with the Gen 2 FE car?

I'd assume its far, far faster on a short 10 minute race. But, it would never make it to the flag on an ePrix?

Probably something like this, they are built for very different things so in their current forms they would probably be comparatively useless at each others tasks. The I.D. R is for a sub 10 minute dash up a hill with high downforce and slick tyres, whereas the Gen 2 FE car is for 45ish minute races on city streets with not all that much downforce and near enough road tyres. The I.D. R is also heavier at I think about 1.1 tonnes whereas Gen 2 FE will be 900kg.  But in pure power terms we're talking 500kW for the I.D. R compared to 250kW for the Gen 2 FE car.

 

I want to know how fast a specially modified Gen 2 FE car could go up Pikes Peak now... how about it, Alejandro?

We have a time up the mountain!!

 

 

 

 

 

7:57.148

 

 

 

That's faster than Loeb - an outright record!!

The I.D. R program is not over

 

An aerodynamic upgrade and then Dumas will take on the Nordschleife to go for the electric record.

https://e-racing365....urgring-attack/

 

NIO's EP9 currently holds the record at 6:45.90 set in 2017.

Toyota had it in 2012 with a 7:22.329.

I wonder why they switched to Bridgestone tires?

Not entirely sure. Perhaps they have used them beforeon a different project/are a known quantity at the Nürburgring and with a short timescale that offers them the best chance of success?

I'm sure they have it figured out, but that looks scary for going over humps.

I really do adore that lower rear wing compared to the Pikes Peak spec.

~1100 kg for an 48 kWh race car does seem like a lot.
900 kg indeed gets you a (RWD only) 58 kWh Formula E car.
Main difference in terms of weight is not the battery size, high discharge cells don't have the same energy density unless perhaps single use. The ID R has an enclosed cockpit and aero that actually creates and takes loads. Often downforce is expressed at sea level, 250 kph but have we ever even seen an FE do that? At 250 kW that should well be doable though, on a Baku like straight and not a 45 minute race. 

Anecdotally, FE cars don't seem to lose much pace after losing a wing.
I'm sure a more ground-up design would get a 48 kWh car of this intent well under 1000kg. But let's be real, VW didn't exactly have the luxury of time, this is a save-face operation, not a race operation. Conveniently, this category offers some low hanging fruit.

For comparison, it's at least 100kg lighter than a (dry?) GT3.
There is more torque and even power.
Much (?) more downforce.
AWD.

Really this should add up tremendously.

Now if only there was ever a single GT3 race car taken around the Nordschleife lap to compare to.... :-D

 

When the Nio EP9 set the record, it was sold to us as a production car record. Despite having been on slicks. Let's be fair then this time, the record was set with a 2-seater than comes with a license plate. And nearly double the battery size and weight. Also, this battery was not really up for the abuse and this power soon dropped to 1/3  or 1/4 of spec'd as I recall. Did it barely do 300 kph on the straight? A Koenigsegg Agera R with less nominal power was clocked at 402 kph there. Similarly, Porsche 918 didn't come past 292 or so there as it had run out of battery power and thus on just 608 hp, uphill, in a not so light hypercar. Porsche 919 Evo (720+ up to 400hp) did 369 kph.
Curiously, that 919 Evo is about on par with modern F1 cars. And that F1 car would probably barely hit 310-320 kph there even with DRS on 850+160hp.

The 919 Evo's time will be safe at 5'19. It's hundreds of kilos lighter and the power well greater.

Look at it hitting what seems like a rev limiter or empty boost while still accelerating nicely, well past 360kph. 

I'd say low 6 minutes for the VW ID R.

Well, if the speed trace graphs on the track simulation video represent one lap they show a little over 360 seconds along the time axis. So low 6 seems spot on.
