Slipery tail ... ???

[Renegade]

Few days ago I had a very unwanted situation. I had to retract to another car (just in the middle of the turn), I was doing about 50-60 mph. And my back end start to sliping all over the road. After 50 meters I luckily stopped the car in the middle of the road.

Now would you tell me something.
Does the P10 has a VERY slipy tail. I think that is called oversteer or override (sorry ).

I have no modifications done to drive terrain.

Thank you in advance

the primera is known to have better handling than most frondrive cars!

almost any frontdrive loses the tail when braking hard while turning... facts of fysics...

I had to avoid some a-hole at the speed of around 60kmh in the rain. It was the second day with the car, and it handled just beautifully. No fish-tailing. Maybe your rear (and front) shocks are gone?

I've had the same problem a couple of times.

It was either loose lug nuts, or uneven front tire pressure.

Have you had your car worked on lately?

_Just a thought_

Yep!

The was on nissan service about 1 or 2 mont ago.
And another thing. Keep in mind that my car has 175/70 13 tires.
That tires means bad handling. I'm planning some 195/50 15 tires. And I think that should do it.

This is exact copy (wheels, color, front bumper) of my car. But it's not picture of my car. Just for a comparison.

Your problem is not with the car but with the driving. Lifting off of the gas in ANY car (front, rear, or all wheel drive) in the middle of a turn is a sure way to rotate the car around the front wheels. What you did was upset the weight balance. By lifting, you took the weight that was on the rear wheels and transfered them to the front. This translated into more ability for the front wheels to turn, and less for the rear. Racers use TTO (Trailing Throttle Oversteer) to help them rotate the car for slow corers. This phenomenon occurs in all cars, no matter the drive wheels. If you are in the situation where your car is pushing (understeering) to the outside of a corner, never lift off the throttle, but rather back off of it smoothly and just a little bit. This will help prevent the rear from stepping out and the also gives the front wheels a bit more grip. Too many uneducated people associate Lift throttle oversteer (also called Trailing throttle oversteer) with rear-wheel drive cars (like Porsche 911's). Lift throttle (trailing throttle) oversteer in rear-wheel drive cars tends to happen a bit more apprublty because you essentially lock the drive wheels while also transfering the weight. Porsche 911's are famous for their lift throttle oversteer not because of their drive wheels, but because of the amount of WEIGHT behind the rear wheels, which means that shifting the weight balance forward at the wrong time can send A LOT more weight rotating, and is thus harder to catch and happens very very fast. ALL cars are set to understeer under nominal conditions, from 911's to Ferrari's to Kia's. The great thing about the G20/Primera is that the driver can induce both understeer and oversteer with ease, and control them ease as well, using varying techniques.

Hope this helps

Umm, I don't know what to say... 100 times thanks. I'll put that in my memory. Maybe some day could save my life and maybe even a car.

Glad to have helped!

similar incident happened to me just over the weekend while I was test driving my P11 with my new TEIN sus and new wheels/tires. I was literally going 75mph on cruise control on the expressway down interstate 55 just 5 miles from the 355 in IL. some chick going about maybe 60mph in a junk mobile without checking her blind spot cut right infront of me. I just slammed on my accelerator and swerved out of my lane 1/2 way into the shoulder and passed her. it was damn close. the sus is setup pretty soft right now, but even so the car was glued to the ground. and I'm not using any racing radials either..just some Potenza RE930's. woke the crap out of me and the wife, but we forgot about the incident like 2 minutes later. G20's have handling!!

nice post gab5b

Is it possible to overturn the car a-side while hard brake-turning?

[qab5b]

Yes, you can flip the car. However, it will be from varying traction conditions. Like if you are going sideways and the road is wet, and then hit a dry spot with the outside tires, the car can flip, as the tires catch. Also, if you are going sideways and leave the road, the outside tires catch on the grass and send the car flipping. Of course the tendency to roll also has to do with the center of gravity (higher means more chance to roll, like suv's).
But if the road conditions are the same (all dry or all wet), and you are driving a car, then you are going to be fine.

Thanks again!

I didn't try it yet, but I sure will.

And BTW (like allways); I got my front bumper on. It's the bumper from 1996 primera/infitiy so it has holes for a fog-lights. I filled the holes with alu-steel fence. Realy nice looking front.

All I have to do to external is: Some sideskirts and wheels.
I'm kinda thin on the money so I'll inform you when I'll make the move

But for now I'm preety satesfied :smoka:

Gonna post some pictures too.

And thanks to everyone for the posts you gave.
