Just out of interest, what circuit are you using for this simulation?

Not even a little guess first???! (I think that the cars have too much downforce/drag to be fully optimised for the circuit so could be a little faster on the straights if that helps...?!)

If we're going to play that game, surely you should post that pic in the "Guess the circuit" thread ;)

I'll just take a wild stab in the dark here; low drag requirement, but that doesn't look like a curve for Monza and the laptime is too short for Spa ... seeing as the race is still fresh in my memory, I'll just go with Canada.

Re: Lower fuel use with current car without dropping perform

If i was to lower fuel use without dropping performance, going on my 2010 data, id introduce a spec fuel tank of 145 kilos, whitch is roughly 210 litres a race. So a 140 Kilo tank whitch is roughly arround 200 Litre tank.

This way designers would have to take the downforce off to gain the fuel efficency needed. Or run the engine lean at stages in the GP. But with this, id take the rev limit off the engines, just to confuse things as well. This way you could see a driver go lean for 80% of the GP and then turn the wick up and post quali lap after quali lap to steal a win or a podium.

WHat i think will happen is that the engines will have a fuel flow restrictor of 2kg per 5km. Wwitch means the engines would have to be just 18% more efficent with fuel than present. So in theory you could take one fith of the engines away from the teams as well. So you would have 7 per season. However with the RPM lift back to 19,000 id keep it to 8 per season. However if a engine blows up, no 9th engines, you have to maximise the distance on all the remaining engines. So instead of an average of 1500km per engine, the average on the non blown will rise to 1850km for instance.

I can also see a limit on transmissions as well for the 2013 rules now.

For future regulations I also like the idea of fixed (smaller) tanks to force efficiency...

The point I'm making here though is that I believe there is a way of using the CURRENT cars more efficiently without making any physical changes.

just close the wheel & cockpit, you save lots of fuel.

Aren't they both CHANGES to the current cars?

Also if u simply put a canopy on the car without any other changes the cars will go faster... but they'll use the same amount of fuel. If u want to save fuel u need to limit the engine output in some way....

Hows about force a standardised fuel tank on the teams, but free up development areas for the engines and KERS systems?? Say bring in the 140 kilo tank i suggested, but free up engine development in the furl pump area and a couple more areas, but areas that can have more power put on the engines, but make them the areas where the engines can be run more efficently. Also lift the RPM mimit as well, makes no sence i know, but the fact that the Cosworth engine has been clocked at 20002rpm makes it the highest revving engine would give the Cosworth teams a boost as well.

As for KERS, allow the teams to more than double the time that KERS can be used to 15 seconds a lap for a 50% increase in power, so instead of 80hp boost, a 120hp boost is given for a maximum of 15 seconds.

Effectivly you could have the V8s peak horsepower reach the 800= mark, and the KERS boost give another 120hp boost. However the standardised fuel tank would be what would drive efficency. The liftiung of the ban on revs would just make engines scream at the end of straights, as well as make engines fail more often.

However id make the engine allocation a strict 8, no 9th engines. So if you are 12GP into a season and you have used 5 blocks, and 2 have blown, you have to maximise the older engines and manage when you introduce a new engine.

Cummon machin, I guessed for you; spill the beans ;)

I don't think it's monza – the end of the lap is too complex. I'm going to go with hokenheim.

Sorry dude, I thought I'd posted the answer earlier today, it obviously didn't work!

To be honest I think I gave you a bum steer with the "less downforce/drag" comment -I only meant a little bit less... its a simple representation of Silverstone (new layout)... the start/finish line is actually a few seconds into the lap (i.e. the graph starts from the end of the last corner, rather than half way down the straight).... I didn't spend very long doing it and just guessed straight lengths from the overhead map on www.formula1.com.... previously I've used google maps to create track maps if I don't have actual data logger info... but this was a really quick one, just for illustration of my proposal... so please don't be too harsh on its accuracy!

Oh, I'm not going to criticise your efforts : you've put much more work into this idea than I have for any of my posts on this forum, so I'd be a total ass if I ripped on you for that ... I may be a pedant, but I respect the effort you've put in here!

Some interesting thoughts in there mate, but slightly off topic... I'm talking about getting better efficiency out of the existing cars without making any modifications (i.e. zero cost) and without dropping either performance or reducing the number of laps!!!

You are never gonna improve efficency with the current regs and aggreements. You need to give a little to take a little.

However there is a way of doing it. Higher density fuel???

Indeed... that's why I suggest taking away some revs (i.e. a bit of power) and replacing it with better aero (i.e. allowing DRS use to be unrestricted)... result -lower fuel use during the GP without dropping performance. I would allow the full revs to be used temporarily for overtaking purposes only....

I wouldn't make any changes for qualifying -full revs and unlimited DRS, as per the current rules.
