Ideally yes, but it hasn't been done yet, so i doubt we will see those possibilities in GT5.
How will pit stops work with electrical cars?

The Tesla Roadster battery pack lies underneath the rollbar. To remove it, you will have to unbolt the chassis and crash-protection from the frame. With quick-release bolts, that'll be about half-a-minute to remove, optimistically, and half-a-minute to put back on. It can be done by a regular pit crew.
But the battery itself... that's the big deal...
We're talking 1,000 pounds of battery. You'll need at least ten men to lift that without a crane... and even with a pneumatic engine hoist trackside, it'll take at least ten minutes to remove one pack and put the other one in.
Unless, of course, you rebuild the entire rear structure of the Tesla so you can drop the battery out of the bottom... as it'd be much, much easier to simply jack up the car off the battery and scoot a new one underneath.
Of course... having a 1,000 pound weight slung underneath the car hanging by a dozen bolts subjected to the stress of frequent changes (likely every 5-10 laps) probably won't weigh lightly on the crew's mind...

There wont be refueling just tire changes...

Or you could make a jack of some sort to pull it out
I'm not saying whether it should be done or not... I'm just saying if you wanted electrical cars to make quick pit stops you could with a bit of engineering.

Under race conditions an electric car would have to only be good for a limited number of laps, it would be interesting. Are they developing any such recharging devices that could be used on electric race cars in real life for quick recharging?

I have heard something about new batteries which can charge up in about 5 minutes or seomthing ridiculously short, now whether the tesla has them or not i dont know but it could be sort of feasible.
I guess fuel cell beats this... just pop in some hydrogen.

I would think that the amount of heat generated in quick charging that many batteries would rule it out.
Easiest thing to do would be just to bar electrics from enduros. Most of them are designed to be city hoppers anyway instead of long distance cruisers (the Tesla is an exception). G-Wiz endurance race anyone?

Should early pioneers have given up just because they could not get a powered plane off the ground for more that just a few seconds?
Nope. But they didn't just rush and try to fly across the Atlantic Ocean.
About recharging - imagine the scene when the "refueling guy" just swaps thousands of AA batteries, one by one. Rest of the pit crew is dying of boredom and irritation and he's throwing "just a second" and "almost done" every few pieces.
Seriously speaking - I have no idea. Perhaps purpose-built enduro electric-juice suckers could have battery-swapping implemented, but Tesla doesn't have that system in stock. How about an available enduro-battery mod, which would enable that functionality and perhaps added a few kilograms?

There's a facetious argument. The cars can do what they can do, and we're stuck with it until someone invents better ones. If we're being realistic, which is kinda the point of GT, there's no way they can complete races of endurance length. The options are either allow them with the knowledge that they can't finish, disallow them or jury-rig some fake system that allows them to go those sorts of distances (long range battery pack upgrade is an excellent idea!).

Maybe to be more realistic you will only be able to enter them in races that are within thier charge life, no endurance races for them, that makes the most sence to me.
Or for a 24 hour race, you would race until before you deplete the charge pit charge the betteries, get some Zzz's wake up the next day and race the final hours.
But seriuosly they would figure out a way to do a quick battery swap or they could just line the tracks overhead with powerlines so they won't need batteries for the cars.

What about KERS ?
Recharging the batteries a bit while braking hard.

Still I seriously doubt they could make it anywhere close to 24hrs, but I don't know for sure as I am not a Tesla enginer.

My buddy and i were discussing the tesla recharge time. If you used a higher voltage line. i imagine they used a standard 120v. you could recharge much faster. tho prob not fast enough for a 10 second pit stop
It's just about the voltage but about the overall power (Watts, P=VxI) but the biggest problem with quick charging is heat, if you attempted to charge batteries required for a electric car in a time that was suitable for a pit stop the batteries would explode.

My Point-> EV's such as the Tesla, GM EV-1, Commuter Cars Tango, Hammerhead Eagle i-Thust, and REVA G-Wiz should be limited up to; 2 laps (on a Nurb-like tracks), 5 laps (on a Grand Valley-sized tracks), 10 laps (on a Trial Mtn.-sized tracks), and 15 laps (on a Autumn Mini-sized tracks). EV's should be restricted on ANY endurance races. It would deliver the most logic and realistic approach of racing these vehicles.

I imagine this will be the case for all electric powered cars, as the claimed mileage of them is dramatically shortened during hard driving. Look up the top gear test of the tesla roadster. Hybrids on the other hand will be able to run in endurance races as they still have a standard fuel/diesel engine.

On board generators would be good for endurance racing. It will keep the racing in pure electric motor. Hybrids will just put bigger petrol motors so it can dominate when the batteries discharge and run purely on the petrol motor so it wouldn't be a fair race agianst all electric powered cars.

The question arises: why did Da Vinci never really build a helicopter?
Of course, he had the technical expertise to try and design one. He had a good idea of how to build the engine to power one. And he was intelligent enough (an IQ between 180-200 is a good guess) to work through the development process. So why didn't he build one?
For one thing, he didn't have the tools, the materials or the industry backing available. Even if Da Vinci were smart enough to build a personal computer, he would not have had anywhere to buy transistors and microchips, nor any of the facilities for making one.
Powered flight was a long time coming because the proper industrial and technical base was needed before it became possible. Human-powered flight took longer because it took decades for materials technology to reach that point.
Right now, there are millions upon millions of dollars being spent on researching and developing battery technology. At the moment, electric endurance cars are still impractical and even if there were a solution, it would still be too costly. You'd need vastly better controllers to balance out the charging and to ensure nothing blows up if you want to charge an electric pack capable of 100 miles within less than a minute... it would require much better battery materials and a humongous amount of processing power packed into a small and economical package.
Not happening... yet.
The Tesla already has "extended range" batteries. Any more extended and it would weigh another half-ton more.
That was faked. They admitted that they "simulated" the battery running out... Top Gear is entertainment... not journalism.
On-board generators still require fuel. And to actually charge the batteries faster than they are being depleted, they'd have to be a dozen times more powerful than the electric motors at the wheels.
At which point, you might as well just connect the generator straight to the electric motors.
Or even better... just connect the generator to a transmission.
Nanosafe was also supposed to be working on this separately, but so far, no product, yet.
Fuel cells would be an excellent answer to this problem... they're incredibly, stupidly, expensive, but they'll work.

Evo magazine tested one and found under 'spirited driving' you'd get no more than 100 miles from a full charge. That was road driving. On a track they got a lap and a half out of it before it overheated and switched to 'power reduced' mode. You'd be lucky to get a lap of La Sarthe at that rate. No chance of even a single fast lap of The Ring if they are going to simulate the car properly.
