Imagine what we could have with tires that were more durable, allowing drivers to push to make overtaking maneuvers on the track rather than refueling to allow drivers to overtake in the pits.

this must be a joke of some sort, or an agreement to avoid the 'farce' headlines we had straight after the meeting. Probably this will be cancelled before it gets anywhere. The clue are the headlines saying its definetely coming back when the reality is that it still has at least 2 major hurdles to clear. Its the same old bernie cheap trick, the first headlines said nothing major was decided, no budget gap and implied this was negative. Suddenly a new headline that detracts everyone and gets people debating the hows.
In the small print of the media report it says the 100kg fuel limit is to be retained AND the fuel flow limit of 100. So whats refueling gonna do? you still cant go flat out on sprints between refuelling cos you still have the same amount left in the pit. So you can start lighter, so can everyone else to exactly match the tyre stops.

Maybe they will have 50kg tanks

They're saying they also target to improve laptimes by 6-7 seconds on average with wider profile tyres and aero enhancements.
I kinda like everything except the dumb refueling bit. My favourite modern day cars were those during 2004-2006 with all their aero gizmos, so it would be cool to have some of that back.

Maybe they will have 50kg tanks that would be the only way to make it meaningful, forcing everyone to run lighter and hence faster. But if its only the weight aspect they want then its an expensive and long winded way of going about it. better to force the teams to get faster by engineering around the weight. Make the tyres perform at peak for longer would increase the speed the same and save money on refuelling - safety rigs and protective gear etc etc

50kg lighter how much faster would the lap time be?

www.fia.com/news/f1-strategy-group-press-releaseFor 2016:- Free choice of the two dry tyre compounds (out of four) that each team can use during the race weekend
For 2017:- Faster cars: 5 to 6 seconds drop in laptimes through aerodynamic rules evolution, wider tyres and reduction of car weight
- Reintroduction of refuelling (maintaining a maximum race fuel allowance)
- Higher revving engines and increased noise
- More aggressive looks
A few other measures have also been discussed but require further investigation before they can be implemented:- A global reflection on race weekend format
- Measures to make starts only activated by the driver without any outside assistance
Giving them more choice on tyre is an interesting move, it would sure make things a little more gambley for some of the backmarking teams which could be interesting but in general I don't think it would make any difference. I'm very much in support for reintroduction of refueling as long as it is safe and there is a stricter limit on how fast the fuel can go into the car. If you wanted to spice it up more you could give teams 5-10 wildcard refueling tokens where they can refuel at a much higher rate to strategically beat other teams. (I don't want this)I would love to see a much more aggressive, futuristic appearance to the cars just like some of the team examples look like. I'm not in favour of higher revving engines or increased noise because I actually like them being quieter, it's nice to hear the crowds and the tyres squeal. Noise pollution is more of a problem than people think so it's the right direction to go down making things quieter. Definately would like to see the measures to make it so drivers can start their car with a starter, sure it makes cars heavier but it means if someone has a problem and stalls their car on track they can re-start it. Not sure what they mean by global reflection on race weekend format, are they trying to consolidate the sessions, are they trying to get more media involvment, are they looking to extend the races or qualifying or simply move practice 3 closer to qualifying (30 mins apart?) I'm glad the 5th engine has been rejected as that was rather stupid, however I still think McLaren should get a 5th Honda engine but only for this year. No other new engine providers should get this if they joined the sport. Looks like they're trying to clamp down on mid-season changes to rules because those who got winter testing correct ultimately are losing out for doing a good job.

50kg lighter how much faster would the lap time be? 1KG is normally between 0.020 and 0.035 per lap. (1 second to 1.75 seconds per lap) At Canada for example it's only 0.025 per lap which is 1.25 seconds if you have 50KG less/more.

(1 second to 1.75 seconds per lap) At Canada for example it's only 0.025 per lap which is 1.25 seconds if you have 50KG less/more. You would have to halve any estimate of the average speed gain for lugging half the fuel load at any on time, because after the refuelling - say at an average half distance into the race - the rest of the race will be exactly as it was bfore the new rule - half tank to carry for half the race. So there would be no net gain in speed in the second half of the race. So the calculation for speed increase by carrying half the current weight at the start of the race cant use previous averages for the weight cost of 1 kg of fuel. All we have to do is look at the 50kg as a percentage of the cars weight and say the car should be on average quicker by the half the % difference I think ive done my own head in by now but simply put, assuming the cars run at minimum weight and burn fuel linearly then say 700 kg for the car + fuel weight so fuel weight is normally 100 = 14% extra weight Say a car can drive at 100% with 800kg take off 50kg = 6.25% increase in performance BUT for only half the race so 3.125% increase. BUT thats only the peak at the start of the race, say the average gain for the first half of the race is half = 1.6secs for a 1.40 sec lap (100 seconds) Say Canada is 1.20 (80 seconds) then the increase will be 0.02 assuming everything with the car is perfect enough for Jenson to not be scared Dammn, just realised thats what Ry said but this is only for the first half of the race, I think i need to have another drink

75 Kg fuel tank would be better so they could split strategies. Half size tank would force everyone into the same choice. The other factor that we'd lose is these 2 second pit stops which are pretty damned nerve wreckingly enjoyable.

I'm confused by your math, my number is based on the start of a race with full fuel tanks, so surely theoretically the improvement with 50kg removed should be even higher because that's a 50kg per lap but obviously with every lap their fuel will be going down so the per lap should get bigger and bigger?
The numbers I used were from what several teams have said before, Williams and McLaren both quoted the same amount of time per lap

The numbers I used were from what several teams have said before, Williams and McLaren both quoted the same amount of time per lap yeah I went on a real ramble around those numbers lol Your numbers are established and credible for the weight cost of a car starting with full tanks, as the weight comes down the speed increases. With half tanks the gain (of halving the tank size) can only be counted in the first half of the race as the second half will be exactly the same as before. So the previous average cost per lap over the race of starting with full tanks per lap in the current format that they normally quote is over a full race, so it wouldnt be exactly accurate to take 50kg off now and extrapolate over the whole race - because the saving now is only in the first half of the race. Put it in simplest terms the speed increase by halving the tank can best be defined as the average lap time over the second half of the race with full tank cars x 2 to get the speed of the car with half tanks. i.e. with full tanks the first half was slow, second half was faster. The new half tank format will be as fast in both halves of the races as the old format second half, but some use the ave lap decrease and times by total laps so as some are saying that the old average lap time will decrease by x amount by removing 50kg of weight averaged over the race are likely estimating a higher speed increase than will actually happen I was on a few bevys when i posted so my numbers are probably skewdif, in fact I could even be wrong now but I dont think the real speed increase will be whats being sold - the cars will be faster in the first half like they were before in the second half, so aint gonna add much to the 6 seconds a lap cut they saying - for the cost and hassle of refuelling

No one factored the better tire life due to the less weight. Guys I am disappointed in you all lol

Maybe the tank will be smaller to accommodate the bigger Energy Store for unrestricted ERS

Did everyone miss the fact that they're planning to introduce wider profile tyres? This by itself could contribute a second or two at least...and aero enhancements can go from 0.01s to Redbull blown diffuser level.
