Display MoreThe Slingshot has huge oversteer issues because of the lack of rear traction, especially when accelerating out of a corner after the apex. This is why the traction control / stability control is so important on this vehicle.
With both nannies on and functioning, the vehicle is pretty neutral though. It is dang near impossible to get a Slingshot to understeer. You rarely see understeer, but when really pushing hard, you see oversteer issues quite frequently.
Luckily, most people will never drive their Slingshots hard enough to have to worry about either one...
In the track video below, I am running traction control off and stability control on. Even is this configuration, you can see how careful I am on throttle control out of the corners to make sure I don't have a bunch of oversteer on every corner exit.
I suppose tires and set up among other things have an effect on whether it under steers or over steers but my experience so far has been exactly opposite to yours. Then again, I haven't had mine on a road course track either.
