Default Does the Rondo have "Traction Control" ?

I have a 2008 Rondo LX. The Rondo specs indicate that it has "stability control". But I have seen some reviews and articles mention it as having "stability control" and "traction control". Is traction control a subset of stability control? I have read articles on the difference between the two features, but I am confused still !
Thanks for your help...

It is a confusing subject as stability control could just extend to a braking system that senses when a car is skidding while a traction control system has to do something that reduces power to a wheel losing traction. My understanding there are various different technical approaches to both problems and that a Rondo equipped with ESC has a an anti-skidding feature and an engine management feature that can intervene when traction is poor.

Richard said it perfectly. The Rondo has both systems but in the US, they have really not made mention of a separate traction control system in the brochures. Take a look at another model, such as the Sportage, and you will see they list it as a stand-alone feature. I think they have done this previously in my opinion. The other Kia models are listed (on the web specs) as having the CVVT engines and Sportmatic transmissions. The Rondo is not, so far. I think Kia would benefit from doing so as the more features they tout, I believe may translate into at least a few sales, if not more.

Yes depending on the car maker a vech might have one or both. And they are seperate systems and do two different things. But that said they(the maker) can go about it in different ways and in fact they can be married and overlapping sytems.

Traction control a straightline system, can have a full or partial brake application to slow a spinning wheel and as well a eng management power reduction feature to help it all along. All used on accelaration. And can be in conjuction with the ABS for decelaration.

Stability control is a handeling system and would not have a brake interface outside the ABS. Applying brakes which will make the already unstable handleing worse is not the goal. But it might have a eng management power reduction feature that kicks in for your own good to slow you down when your getting in over your head. As well as a shock stiffening feature to help with the dip and roll.

Again just how much and which way they go about it is up to them but you can see the overlap in theory. Hint here is, the more a vech $$$ the more fancy the system and features.

Think 2008 Kia Rondo LX $19,000. ABS and Eng power deduction only
And a 2008 Rolls Royce Phantom $235,000 will have every bell and whistle and system interconnected so you do not even know it is there or care. The Rolls will not smoke a tire pedal to floor from rest. Nor lock up a tire no matter what pedal to floor. And it will never go into a increasing radius exit ramp at 60mph and not come out the other end with you sweating. Turn wheel point it and stand on brake, at end of ramp proceed again.

I think you will find, upon further investigation, that applying specific brakes is a well used part in most stability control systems. The systems are mostly set up so that the application of a single wheels brakes or perhaps two wheels is a very important portion of the system.

Very high end if that. MB/MAYBACH/ROLLS/LAMBO/MASERATI ect. Nothing we will ever see in here for sure. Your point is well taken if missing the mark a bit. And when it is, it is more on the traction control side of things then the stability. One or more or what ever brakes being applied at speed pulls and throws the car off balance just like as if you had a bad sticking caliper. Do not confuse RANGE ROVER "HILL DESENT" with a brakes being applied for STABILITY at speed control measure.

A perusal of the section under "Electronic Stability Control" should be informative and highly educational in this instance !!!

As far as I've seen. My 08 Rondo EX has ESC which includes Traction and Stability Control. Haven't tried out the Stability Control feature. But the Traction Control does kick in when I floored the accelerator. I can see the ESC light flash on the dash and feel the engine slowing down in an attempt to control traction.

I then turned off the ESC and did the same thing. I ended up with more wheel spin and no ESC light flashing.

So my answer would be yes. The 2008 Rondo EX-V6 does have Traction Control. I made sure of this before purchasing the vehicle.

Yes, Rondo has both Traction and Stability control. These are two main components in addition to ABS, and electronic throttle control.

1. It has Steering angle sensor
2. Yaw Rate sensor

It does cuts the power even when you are in straight line wheel slippage is detected. But it would not stop wheel from completely slipping, once slip starts( few rotations) then engine power is cut.

In the case of turning it uses the Steering angle sensor and yaw rate sensor and detects the vehicle slipping, then apply brakes to individual wheels and reduces the power.

BTW, I get to try all the features last year during a sudden heavy snow. Stability control worked as intended, but I thought it is cutting too much power.

As far as traction control, it did work by cutting the power, but not by individually applying the brakes. I had good hope about traction control, but the implementation is not sophisticated as my friends BMW, when it applies brake to slipping wheel so wheel with most traction gets the power.

I had to go over a small ramp(not too steep), quite few vehicles were making( not all are making it because of heavy snow), wheel kept slipping and engine is cutting power completely, so no forward moment, so I ended up turning off the ESC, and stabbed the throttle, with some smoke and lot of slippage I was able to climb and go forward. I am still not sure why they did not opt to implement individual braking for traction control, that seems quite silly.

Probably because it is a more expensive way to do it than just using the throttle control.
