Finally a proper race by Audi. The've got the best car but they had a lot of problems. Good job Daniel as well, beating the world champion in a fair manner.

It goes to show without the DSQ after the win in Hong Kong, and the technical issues in HK, Marrakesh, and Santiago the season would have shaped up very differently. That's racing I guess, sometimes the best team doesn't win.

I've been hugely impressed by Abt this year, I must admit through season 1 & 2 I thought he was only there because his family name was above the door. On the other hand Prost has gone backwards in my estimation, I was expecting a lot from his team Rebellion results, but he spectacularly crashed in the 1st race and never really got going since. It's very likely he'll be out on his ear when Nissan take over - they may find it hard to keep Buemi with his Toyota commitments as well. Could be that there are a load of seats up for grabs over the summer! Gotta question what's happening at Renault to be so consistently beaten by the customer team is baffling!?


On brakes - as everyone is talking about - Coulthard mentioned in FP commentary that the diminutive disc size and lack of a cake tin/air duct may help to keep the tyres cooler - seems getting brake temps without overheating the tyre could be an issue. An idiosyncrasy of the "road" tyres they run?

I'm really buffled by Prost; Nowhere near Buemi especially this year. At least last year he was consistently in the points, nowadays he fights in the back. It makes me wonder..

Please, don't mention customer team beating the works team, it hurts. I support Yamaha in MotoGP!! :mrgreen: :mrgreen:
On a more serious note, I think that Renault has made steps backwards, because Buemi isn't at all competitive, today for example, even with the fan boost, he couldn't get near Vergne. As much as I don't like Vergne, he is doing a fantastic job, he is really cautious when it's absolutely necessary. That said, it really is difficult to lose this championship; when you're closest rival is Sam Bird, what can you do wrong.

Last note, we're going to have two Venturi teams. The HWA one will be the pre-Mercedes, will Nico drive for them?

I concur with you on this one, strad.. it beggars belief that Brembo would fork out full F1-spec brakes for FE,
or imagining that simply rolling an eye or two - over a couple of publicity pix, could confirm this to be the case..

I missed where someone, other than you, suggested the brakes are “full F1 spec”.

This , viewtopic.php?p=766187#p766187, is the most cogent post on this and suggests that they are similar in diameter and offers no suggestion that any other aspect is lifted from F1 ( maybe with the exception of the BBW)

I looked back thru every post "I" made on the topic and not one from me says I think they are full F1 spec.
I was responding to @J.A.W.. Sorry if you thought I meant you. I should have pruned the quote.

Well Massa is in one of the Venturi seats, I think Engel will be retained in the other. I don't see Rosberg racing - I think he's being lined up as the team principal. He's currently an investor in the series, but Agag is trying to buy out all the other investors. Wehrlein is being talked about, but I think you have to get Formula E to be competitive - loads of good drivers have struggled because they're not fully committed to learning its quirks. Di Resta has tested and is a current Mercedes DTM, there's also Mortara who had a good HK until he crashed, then nothing. Those are the 3 contenders for HWA for me, unless I'm missing someone...

On Renault, I think they have to sell the exact same specification of powertrain at a fixed price so the only differences must be drivers and software. I don't see much difference between Buemi and Vergne so it has to be software issues.

I quite like Sam Bird, the Virgin is a bit up and down but he consistently quicker than Lynn. Rosenquist may be pushing Heidfeld into retirement, if only he could stamp out the mistakes, again the car can be unbeatable one day and at the back of the midfield the next.

Anyone have an idea what his lap times were?
I know they would not be representative, just for fun

If they recorded times they've not released them. I timed his last 3 laps (after the lock up and brake bal shifts) at 1:13.7, 1:15.5 and 1:14.7, it's difficult to judge where the timing line is because of the camera angles, could have picked a different reference each time, so say a 1:14.4 average! Pole was a 1:09.472 and the best lap in the race was a 1:12.409, but Abt was averaging ~1:14's. So if he wasn't pushing he was doing similar lap times to the average race pace of the winner.

I'm not sure what power train was in the car.. he was asking about when to shift into second, AFAIK none of the top teams have multiple gears any more so it could be a motor/inverter borrowed from a team (Renault/Audi S2?). We also don't know what power mode he was in... but it's unlikely to have been 250kW. There's also the issue of setup for a demo run, it looked stiffer than the other cars over the bumps so maybe they used what they have done in testing?!

Agreed! You would have thought he'd do his homework beforehand though :lol:
