I just spotted this video on YouTube. Its really amazing how little speed and lateral Gs it takes to roll one of these things. This video sure puts it in perspective.


The Slingshot may look like a high performance machine, but it seems it actually handles the road about as well as a Reliant Robin.

Single person driving versus passenger as well might make a huge difference with those things.

You have severe over steer causing this one. well and no knowledge of lateral G's.

when a nascar or high speed racing car enters a turn, ther will be almost no "correcting" the steering mid way, you enter the turn and hold the line!

With lack of how to counter-steer. I'm seeing this with a lot a 4 wheelers. People just don't know how to drive anymore.

I dont see any oversteer. I just see the front of the car come up. And oversteer would actually release all of the lateral load at the rear when the tire breaks free. Its the fact that the rear tire has such excellent traction that causes the vehicle to lean.

Frankly, I dont see any traction problems in that video, just a problem with roll resistance - as in, it has none at the rear.

You cant counter steer in a tight corner like that. If he tried to counter steer the car would have headed for the outside of the turn and shot off the road like a rocket. Something tight like that turn theres just no room.

Look at this video. I would have 100% eaten the wall if I counter steered. It would have caused the car to dart to the outside of the turn and as soon as my tire hit gravel and lost traction it would have been all over.



I think the cause of the slingshot accident is simply that on that steep hill, on corner exit, all of the weight transfer goes to the rear drivers side corner of the car, but there's nothing but air there so it rolls. Since its built opposite of the reliant Robin (rear trike vs front trike), it makes sense that the Robin flips under braking on corner entry, when weight transfers to the outside corner where there's no support, and vice versa the Slingshot rolls on corner exit when you get back on the throttle and induce the weight transfer to its rear outside corner.

An example is the infamously dangerous Ford Fiesta ST. These cars are a rollover hazard. Big time. Don't ever get in one. But it provides a fine example here. If you get it up on two wheels and counter-steer its a huge change in direction. He immediately got offline and missed the gate by 10 feet. That would have put the Slingshot head on into a tree, probably without scrubbing much speed.

I’ll go along with this but I still say counter-steering might have saved it. He’s already headed into the other lane so he has nothing to lose to try bringing it back down. Watch NASCAR drivers and you’ll see them counter-steer when they break but then that’s mostly the rear end. The Slingshot is a totally different animal. Far as I’m concerned they should never have allowed them on the streets but that’s just my opinion.

Having owned and highly modified two of these personally, what happened in the video is not possible when driving stock Slingshots, which come with traction and stability control.

The video contains a highly modified Slingshot, done in a very improper way (from what I see in the video, not seeing it in person). There's a large luggage rack out back, behind the rear tire, up high. Such a modification changes the center of gravity significantly, and not in a good way. This causes the rather odd body roll that normally digs in around corners due to weight transfer to be exaggerated, and unlike the blue Slingshot in front of it, this one grabbed, stuck, and flipped.

If running that corner with sticky tires and lowered & tuned race suspension those Slings would have stuck like glue.

Happens all the time. There are countless videos out there of the slingshot rolling like that. This one was just shocking because it was such a low speed. But they flip all the time. They literally have half the roll resistance of a 4 wheel car.




Also, I cant find the video at the moment but they tried using these things on some televised race series and couldn't keep them upright.

No, it does not happen all the time. What real-world experience do you have to make such a claim?

If I remember correctly, that video is from when Slingshots first came out and the driver disabled the stability control so the engine wouldn't cause deceleration around the cones. His non-typical driving caused an excessive weight-transfer so the front "dug-in" and caught.

I have a friend who modifies these bad boys, superchargers, turbos and what not. I believe he does suspension mods as well. They are stable if driven properly. They did all the work on my Solstice.

Non-typical? To me that looks like a pretty standard emergency lang change setup with the cones. Thats exactly the sort of thing you encounter when someone cuts you off and you have to swerve.

But also, you're admitting that without electronic nannies the three wheeled car is a death trap. If youre a blown fuse away from rolling one of those things, then it does not change my assessment.

Well, if I needed advice on sex I wouldn't ask someone who watches Internet porn in their mom's basement.

I realize you're in the middle of an older Honda rebuild, but you're way out of your league here.

Not that my pedigree is relevant to the substance of the argument, but I have 10 years autocross experience, and though I was not the one driving, I have built a Prosolo National Championship winning car. Suffice to say I am no stranger to vehicle dynamics...

I've flown in many, many jets, but that doesn't make me an airline mechanic any more than going to a concert makes me a musician.

Respectfully, if you drive one you'll quickly realize they're not like other vehicles (they're basically concept cars that made it to production). Wrenching one...that's an experience. Stability control is in the ECU, so if you blowing a fuse that wipes out the stability control you're not going anywhere (no ECU).

There are handling peculiarities on the stock Slingshots, analogous to the handling dynamics of an open-cockpit bathtub on three wheels.

Similarly, I wouldn't dream of racing autocross without heavy modification to an appropriate vehicle..."Hey, look at that hedgehog in a stock Chevy Bolt!" :ROFLMAO:

(I don't even own a Bolt in real life...)

That's Civic has seen quite a life under my stewardship. I once lifted it 2" and took it rallyxing.

I've cut the fenders and stuffed 275/35/15s in the past. We've been through a lot together. I love this car a lot more than the others.

Modifying a slingshot makes it more prone to rolling over. Anything you do to add grip makes it want to roll more. The only thing you can do to reduce the roll potential is to reduce the traction. Put like 3 space saver donut tires on it so that it will break traction instead of building so much lateral load. Or add a rear axle or some sort of training wheels type thing.

In the first rollover, it didn't look like he was going any faster than the other two before him. I thought he may have dropped his right front tire off the edge of the pavement, over corrected and flipped himself. Maybe?
