Considering buying a used rcf. I’ve read rwd cars lsd can help a lot in the winter.

wondering would the tvd react the same way?

 

I have no experience since my RCF is garaged during the winter, but I know someone who owned two RCFs in Toronto. His first one was an LSD (2015) and the 2nd one was a TVD (2020). He claimed the TVD handled so snow much better and was actually very fun, controllable in the snow. @Jackal44 lives in Calgary like me and drives his TVD/CF RCF during the winter so he can shed more light on how TVD handles the snow

 

TVD will handle snow better than an LSD. If the TVD notices slip on one wheel it'll send power to the other (up to 100%). A torsen would need at least some grip on BOTH wheels to help in snow.

 

No, definitely not. The TVD sensors must be directly related to steering angle at speed vrs throttle input. I say “must” because that’s how I believe it works based on driving mine and trying to figure out how it works. And it, clearly, feels like it’s based off the steering input. Not by road traction. So, there’s no way the TVD would impact snow control.
I would say avoid trying to winter this car, though it probably would very easily with the right tire setup, because the weight of this car really requires you to have a great summer performance tire to feel like a sporty coupe. Just My opinion.

 

On the topic of wheel spin and TVD, I think you must be thinking those dumb budget, TVDs that are brake based systems like Acura's SH-AWD. The TVD in RCF is extremely smart and proactive. It actually uses sensors to monitor wheel slip and can adjust the torque split/shift side to side based on traction in 1/1000th of a second as stated above. I personally agree with driving in the winter in snow, but that is just my opinion.

RCF gets a mention here

 

its directed to steering angle but ALSO wheel slip. As long as one tire can get traction the TVD will help....the LSD needs both to have at least some traction to help.
