A different Delta Wing article

I don't see the revolutionary aerodynamics or the small frontal area. Frontal area is the area of the entire profile of the car, it's just as wide at the back as every other car.

If the shape is really what makes the difference then why not build it to the same weightnand power as the competition and see how it really compares? Playing by your own rules does nothing to prove the concept.

So the car is one of the faster P2 cars going down the speed trap- 188 during the race, 190 during practice, with 150hp less. Something must be low drag.

IMHO, a better way to do that is limit fuel flow. That way you get a reasonable range of power available, and you let clever engineers find ways to get more power out of less fuel. But that's a different thread.

"Here is your tanker of fuel. How far can you go in 24 hours?" I like it. I'm not sure you can separate the aero from the rest of the Delta Wing, honestly. It was a different concept. The packaging allowed for the weight distribution that let the packaging work. Watch the video of the crash, it's fairly clear what happened. Lots of cars, not much visibility, a loss in situational awareness on the part of the Toyota driver. I don't think any other car would have fared any differently.

FWIW, the fuel restrictor is in the 2014 rules. Open engines, flow restrictions. Wish I could find an offical website, but....

I wish there was a class with no rules. How far could a car go in 24 hours without any rules at all?

How do we know it had 150 hp less? Because they said so?

Precisely half way around the world at 500mph.
The deltawing exceeds(suffers) at the laws of physics. If you up the weight, the hardware holding it together has to be stronger(heavier), then you need more power to accelerate it off the corners equally to the other cars. Which in turn means you need stronger (heavier) drive components.
Adding power or weight drives the absolute minimum weight up. That includes fuel weight. The car could have run more fuel for longer stints had the ACO not limited the volume. That increased weight will drive shorter tire runs, even though the car was able to run 8o laps on tires during the test day.
Ultimately, the car was an excercise in engineering everything to the nth degree BECAUSE it did not have to fit any specific rules package.
