2014-2020 Formula One 1.6l V6 turbo engine formula

[Juzh]

I agree with what you say but the 2010 car was different and it's optimum point was different compared to today's car.
In 2010 they could not run very low downforce to current car level as they also need some grip around the corners.

Right - and what makes you think that they don't need grip around corners in 2015?

Anyone have sector 2 data from Webber and Hamiltons laps?

Webber had pole, but fastest S2 was done by Vettel (1/10 faster than webber)
2010 Sebastian Vettel 45.493
2015 Lewis Hamilton 47.786

2.3s difference. RB6 simply can not be matched by any modern gimmick engineers can come up these days with water tight regs.
2010 cars are faster even in S3.

And just to compare V6t vs V10:
Best S1 this year was 30.5s by rosberg. 2005 best S1 28.8s by fisichella.
V10 power owns all.

Juzh, where did you find the sector time info?

[Blackout]

V10 power to weight ratio is no match to today's cars. 900-950hp/605kg vs 800-850hp/710kg
The 2010 p/w ratio isnt bad; 1.20 (2010) vs 1.19 (2015) + much ore downforce

In 2010 there was no DRS on cars.

F-duct did as good a job as DRS and was used everywhere. Concern was that year that Red-Bull would do eau rouge with the F-duct blowing.

[Tommy Cookers]

to me this seems to be the right time and place to ask these questions arising from the race we just watched ......

with the fall in power from V10 to V8s iirc Eau Rouge was no longer a grip-limited corner (likewise some others generally)
is ER now again truly grip-limited or is there any cornering margin when flat-out ?
race or qually dependent ?

[Sixbarboost]

I would suspect so, not so much power-wise, but due to less downforce and the Pirelli tires?

[Cold Fussion]

Eau Rouge is flat out comfortably in qualifying.

Depends on the car. Race conditions on mediums I think actually very few cars could go flat and even then only merc could possibly do it easily. I know for a fact grosjean couldn't do it on various stages troughout entire race and even had to lift for blanchimont believe it or not. RB was flat trough and trough both corners, but was on soft tires so it's not a like for like comparison.

Edit, ok found grosjean on softs lifting massively trough eau rouge and blanchimont starts at 15:15

compare to that to Ricciardo at 16:50, just before he retires (he's on medium tires as well). Not a hint of lift.
Then check out Kvyat at 22:25 going flat trough ER carrying some 10-15 clicks more than the car in front and grosjean earlier.

Eau Rouge is flat out comfortably in qualifying.

Yeah sure, got any onboards to prove that? As you're trying to make it so obvious it's THAT simple. STRAT 1 made sure it wasn't.

Merc so good example

Considering how close the sector times are for S! one can assume that just about everyone, if not everyone is flat through Eau Rouge. The LMP1 cars are also flat through Eau Rouge, even in the race.

From Autosport.com
Andy Cowell:

"All the work around combustion efficiency is very potent, because you've got 1240KW potential in the fuel with it flowing at 100kg/h, so the day we get to 100 per cent conversion efficiency, we will have 1240KW as well as the K. That's our aspiration before we retire.

So there you have it. Specific energy is 44,64 MJ/kg for Petronas fuel.

delete please

I'm not convinced that's flat out in a F1. And as for LMP1 cars I know they can't take it flat out.

I hoped that this eau rouge drama would have ended...several drivers in different interviews during the last years said that present F1 cars are perfectly able to go flat out: (e.g. I remember alonso's one in 2014)..
I was there two weeks ago and I can confirm that in qualify most, if not all, drivers went flat out
