http://thelede.blogs.nytimes.com/2007/07/0...id-speed-demon/ Go there for today's lol. Has anyone read mpg while doing 100?
According to Wayne Brown's program, at 330 ft. elevation with no wind, 80 degree F and 60% humidity one would get about 32mpg at 100mph.

I was thinking about 30, my thinking is that on flat highway I get about 50 - 55 mpg at 60 mph, and I read somewhere that mileage drops about 10% for every 10 mph over 60 (according to US EPA). so that would be about a 40% drop from 50.
<div class='quotetop'>QUOTE(ystasino @ Jul 5 2007, 05:10 PM) [snapback]473700[/snapback]</div> Maybe in a 24 hours of lemans type race but what would it do for f1 where races are full-throttle sprints for two hours? You wouldn't want ice power going to charge the batteries, so if you used regen power you'd could use it once ever few slow downs at the expense of battery weight and extra motors. Although the idea of f1 money going towards battery research would push that technology much faster than it currently is happening.
<div class='quotetop'>QUOTE(douglas001001 @ Jul 5 2007, 07:04 PM) [snapback]473723[/snapback]</div> but if done right that could possibly be one less pit stop for gas
<div class='quotetop'>QUOTE(morpheusx @ Jul 5 2007, 06:08 PM) [snapback]473724[/snapback]</div> They already can finish in one pit stop, but most teams go with two stop strategy to run more laps at lower car weight. I'm just saying that since the ice is always in peak power range, I don't think an HSD type system would help overall performance/efficiency, which is what I was guessing the earlier poster was meaning. The amount regained by regen would have to overcome about a 2 second/lap time reduction due to extra weight (lap times are 2 seconds slower after pit stops usually, so assuming batteries/equipment weight is the same or more), and there would rarely be excess power from the ice to go to the batteries. If they could change batteries at pit stops, now that would make it interesting assuming battery power isn't tied to ICE/regen. I wonder if Bernie has seen Inconvenient Truth? Perhaps if he got caught up in the eco-revolution he would go down as more than someone protecting their own monetary interests.

Formula 1 is not not nascar. They are varying speeds constantly the race is like a yoyo when turns are on the track. Watch cars slow down and speed up CONSTANTLY if anything the biggest source of improvement would be regeneretive braking that's where most advances i would say would take place. Taking a car down from 300km/h to 80km/h or less during hairpins requires a lot of braking force as it stands right now.
<div class='quotetop'>QUOTE(ystasino @ Jul 5 2007, 05:10 PM) [snapback]473700[/snapback]</div> yes they should, but the rules don't allow it.... pehaps hybrid racing will emerge as a new category?
<div class='quotetop'>QUOTE(efusco @ Jul 5 2007, 05:04 PM) [snapback]473693[/snapback]</div> Just watch. Now they'll start claiming the Prius only gets 32 mpg.
<div class='quotetop'>QUOTE(ranmandx @ Jul 7 2007, 09:00 AM) [snapback]474604[/snapback]</div> How are you defining improvement? In f1 it is a function of lap times. Adding a couple hundred pounds to a 1300 pound car is a big penalty to overcome with the current setup/rules. The linked article states the fia is considering it for 2011 (thanks for posting it jbreynolds), and would accompany significant aero/engine changes to make it a better overall package. The idea of f1 spending multi-millions of dollars on regen and battery technology should get everyone on this site overcome with joy. If the proposed rules get implemented in 2011 the race turns into who can get the most out of their regen and batteries and that means many times the amount of money currently being spent on developing the technology.

<div class='quotetop'>QUOTE(douglas001001 @ Jul 6 2007, 01:04 AM) [snapback]473723[/snapback]</div> Right logic, wrong answer And the winner is: Super Diesel TDI "The winning car’s average speed over the entire distance was 215.409 kph (133 mph)." Hybrid will carry useless weight of batteries and other hybrid drivetrain components most of the time on this track. Le Mans
<div class='quotetop'>QUOTE(HiLaker @ Jul 7 2007, 03:19 PM) [snapback]474743[/snapback]</div> An HSD like system wouldn't be more useful in endurance racing than a short sprint like f1?
<div class='quotetop'>QUOTE(douglas001001 @ Jul 7 2007, 10:53 PM) [snapback]474752[/snapback]</div> I think that HSD will not be efficient in Le Mans driving cycle as batteries will not be able to absorb or deliver enough power. If it would, Toyota will be there to demonstrate it.
