All Wheel Drive And Torque Vectoring

[Insignia driver]

To add to the first post in this thread:

• GKN Twinster system (Ford Focus RS, Lincoln MKZ and Lincoln Continental)... and 2017's new Opel Insignia B and its Buick & Holden analogues
• SAAB XWD system (Saab 9-5, Opel Insignia A) - Haldex-based AWD + another Haldex coupling on the rear axle, acting as an active eLSD - electronic-controlled Limited Slip Differential. It works just like Audi's Sportdifferenzial, by actively splitting torque to individual rear whells in split-seconds time, according to current car movement conditions, and basing on data from numerous sensors (incl. yaw rate). And NO brakes are used.

Welcome aboard, @Insignia driver! Thank you for signing up!

I have an Audi S4 with the rear sport differential (and considering the Kia Stnger GT).
The first time I drove the car in dynamic mode and made a fast left hand turn from a stop at an intersection,
the back end felt like it was going to "wildly" over steer...a real eye opener.
That's how well the torque vectoring works. And it was an $1100 option on top of higher MSRP.
I would definitely prefer "active" torque vectoring to brake based but I don't track the car so I won't let that be a deal breaker.
I'd be ok trading a slightly sharper handling 4 door sedan to a larger 4 door GT sportback.
Really depends what's most important to you.

In Canada, where we only get AWD Stingers and Genesis G70 (sister car), the real LSD is not available at all on the Stinger, but standard equipment on the G70. This is very annoying to me as I would prefer it to be at least an option for the Stinger.

Retrofitting it will always be an option, but the question is software. Will the more active mechanical LSD just dampen the amount of brake-based torque vectoring is required (plug and play), or, will it only work optimally with updated stability control software? KIA supplied an AWD car with the LSD for the European Car of the Year (COTY) journalists, so we know it is possible and coming as an option at least in some countries. Of course the COTY cars also had updated shift logic and bi-modal exhaust, too. With these three options, the Stinger would be perfect in my books.

Really sorry to resurrect this old topic but I was just reading today (1 year after I bought the car) about LSD and Torque Vectoring. Based on how my car behaved and due to the lack of info from my dealer I assumed I have LSD fitted even though I have the 2.0 GT-Line. Most of these here in Europe have it as standard.
However, today I just pulled out a full list of specs for my car (based on it's VIN) and it looks like mine doesn't have LSD but has Dynamic Torque Vectoring Control (5897A1). It's a RWD car!
When I use launch control, it definitely applies almost equal torque to both wheels because I can leave equal tire skids on the asphalt. As far as I know a simple open diff can't do this (it's near impossible to replicate).
So, what's the deal? Does the RWD comes with Torque Vectoring and is this able to act as an electronic LSD?
