Centripetal Force when Turning

[big_stomach_cow]

Hi everyone,

I have this strange feeling every time when I drive my BL when I am on the ring road to get on or off the highway. I do not know exactly word to descibe the type of road due to my language limitation, so I screenshot a map and point it out below.

I pretty sure I am not speeding, but every time when I drive on those type of road, I feel very strong centripetal force; I almost feel my car will rollover. Anyone has same feeling, and any thing I can setup or adjust from car to make this go away or reduced?

Also, when I drive around 110km/hr on high way (straight direction) I feel my car is so light, and a truck pass me can blow my car away. Any recommedation to make this "feeling" go away besides I drive slow?

Thanks.

Anytime you drive a vehicle with height, especially a truck or suv, you will experience this centripetal force. But the Bronco Sport is unique in all the trucks and off-road suvs I have driven in that it has the taller boxy frame but has a tighter turning radius. So, if you are not used to this I suggest two things:
- slow down before on the turn
- once in the turn and you feel it losing control, accelerate. You think that braking is smarter but due to vortex force, that counter-intuitive action is what you want to do (if you doubt me, ask any good motorcycle rider)

And let me clarify, the first option is the smarter one, especially if you ever have that feeling you will lose control.

As for the truck passing you feeling, I’m sorry but I usually drive around Chicago. We don’t let’s no one pass us, especially no truck.

Try that driving with a two door Jeep Wrangler! A lot has to do with the height, weight, wheel length, and vehicle width, mostly the height and wheel width. The narrower and higher the vehicle is, the more "topsy turny" it will feel.

Years ago (I am showing my age), Pontiac used to advertise "wide trac", meaning their cars were lower to the ground, and the wheel base was wider, allowing for more ground grip.

I owned a 1961 Corvette. It had the skinniest tires I've ever seen on a Corvette. I drove it from North Carolina to Pigeon Forge Tennessee for a car show. Driving through the mountains going west was a beautiful thing. The convertible top was down, a gorgeous sunny day. However, the tires squealed the whole trip through the mountains. I wore out the front tires on that trip! A call to Cooker tires for a set of wide whitewalls to replace them was expensive.

I guess the Corvette at that time was engineered for straight line speed only.

All of what @Tigger and @Bucko said, including that the suspension on your vehicle is a compromise between acceptable road manners and off-road capability. That means the wheels move up and down more, and springs are softer than you are used to. Softer springs means the body rolls a bit more to the outside of the turn.

The next time you are going around those curves pay attention to the road. If the road is tilted toward the inside of the turn that will tend to help with body roll. If it is flat or tilted toward the outside of the turn that will tend to make it worse. If you know a curve is flat or tilted the wrong way you must go slower around them.

Mark S brings up another valid point to road tilt. I used to wonder why the DOT (department of transportation) build roads that have a slight tilt. I was told it helps with rain drain off, as well as assisting in anti body roll on curves.

Thanks @Tigger , @Bucko and @Mark S. I think spring is one the reason; well drive with caution and within speed limit when turning are the correct action to take.
