Nissan DeltaWing

Have you seen this before?

I stumbled across it this morning on the TG site.

Yea this car will run the 24h of le Mans Im looking forward to see the result

it was originally a sort of design concept from IndyCar (as a demonstration of a rules package that would have brought IndyCar partway back to the days where teams and manufacturers could design their own car) but it was rejected because people got hung up on its looks (including me)
The designers didn’t want all their work to come to nothing, so they put in an application for garage 56 at Le Mans, which means they would be allowed to compete with few regulations but would not be classified, and thus they will be ineligible for the win.

I think I saw Surströmming on a TV show a year or so ago (it would have been around the same time I joined this forum), and thought that is awesome. A canned food that continues to ferment and smell so bad, but people still want to eat it and buy it! :smiley: I think I also remember the cans can go out of shape if they’re left too long! How excellent is that?! :smiley:

Plus the design on the can is so cool too. I actually wanted to have t-shirt made with the logo on it. I like different things and Surströmming is certainly different! (BTW, I don’t actually eat fish. I can’t eat fish, more to the point :blush: )

This Nissan DeltaWing is also different. I wouldn’t say it is the prettiest car in the world, but it does capture some attention with its different design. I think it is good they’re willing to try something different!

I guess Batman doesn’t need this car anymore.

I’m really curious how well that design works out. It seems likes it would be more tailored for straight line speed with the front wheels so close together.

That’s what I thought at first, but it works on 3 levels:
1:the wheels are a long way out in front and thus have good leverage
2:the weight is mostly in the back, which is something race car builders strive for
3: the braking is mostly done from the rear wheels, drastically improving braking stability

Hmm, you’d probably fall asleep driving an LMP1/2 that slowly round Sebring (I loathe Sebring anyway), so we still know nothing about how well it actually works :stuck_out_tongue:

At first I thought this was one of those salt flat top speed cars but now I see that its an actual track car… I don’t really know how I feel about this. Seems too radical. But who knows, Nissan knows what their doing it seems.

Bah, it’s not Nissan’s design. They’ve just supplied the engine for it to run in the Garage 56 (non ranking) entry at Le Mans since it failed in its bid to become the new indycar reference (which is what it was built for.)

I now see that after further research. lol It is still quite intriguing.

But… Umm… That’s wrong. :neutral_face:
1:Long wheel base = bad for turning. Think of the MX5. A shorter wheelbase means quicker turn-in as there’s less circumference to the turning circle.
2:Not 100% on this myself, but I’m pretty sure that racing cars are built for as close to a 50/50 weight distribution as possible. It aids with grip and handling.
3:Braking done from the rear wheels isn’t stable at all. What happens when you pull the handbrake in your car? It slides all over the place! :laughing: This isn’t a bad thing, but I’d bet most racing drivers with the exception of drifters would disagree with me!

I think it’s design rocks, but it wasn’t allowed to run in the actual le Mans race, was it? It participated for show and testing if i don’t remember totally wrong.

No it did run and ended up crashing with a Toyota youtube.com/watch?v=FJAiZVuC3YI

It didn’t fit any normal classes so they entered it in a experimental class.

1: You’re right, but this car uses torque vectoring, it means the rear wheels are doing great part of the job of turning the car. Put more torque on the external wheel and the car will turn.
2: Yeah you’re right again, but this applies to “normal” cars, where rear wheels push the car, front wheels turn the car. But the DW is not a conventional design, and can’t be annalyzed in a so simple manner.
3: Sorry but you’re wrong in this one, pal. With most of the weight on the back, the rear wheels will have sufficient grip to do most of the braking, as opposed to normal cars, where the weight is shifted to the front, and the rear wheels get less grip (remember: friction = mu*N).

It looks like something you would see attempting a speed record ?

I think it might actually fly… :laughing:
