Cupra R LSD?

I had the same of thing as EDL in my corolla t-sport, whilst cornering if you gently fed in the power, you could feel it use the front brakes on the inside wheel for fractions of a second, felt wierd but it did work to pull the nose in tighter than it would had it not been there. It was difficult to exploit though, and provided no help from a standing start.
 
Main point is they still use a normal Open diff rather than a fancy proper one, ala Quaiffe or TorSen
 
I've always hears that LSD's make the steering not so pleasant (On Front Wheel Drive cars) - is this true?
 
They "can" make them a little weird on uneven surfaces, but that's not to say that all FWD LSD equipped cars are like that, nor that its a huge problem either.
 
To be fair, it wasn't that bad with mismatched tyres.

Ask Sam what it was like when he went out in it... I think his words were "It's a Rover, why does it have so much grip"

lol

Electronic Differential Lock. The electronic differential lock (EDL) permits smooth, comfortable starts on road surfaces that do not have a uniform coefficient of friction. If a wheel starts to spin, EDL brakes it as necessary so that power is transmitted to the wheel with the better traction. EDL reduces tire wear and works up to about. 40 km/h (quattro®: up to about 80 km/h). EDL is part of the electronic stabilization program (ESP) and the traction control (ASR).

I'm not sure thats entirely correct - as far as I'm aware it only brakes the wheel which is losing traction, it doesn't transfer power across to the wheel with better traction....

And LSD's are fantastic on FWD cars - I'm having one fitted to my GTA as we speak - because after driving the ITR for so long, you really miss it.

Bear in mind there are LSD's and Torsen Diffs - they're slightly different. I'm having a Torsen diff fitted to the GTA (ITR was Torsen too). Not 100% sure on the techy differences, Google will help though.

Well thats from Audi so if you want to tell them otherwise...

Err... what do you think will happen if you brake one wheel whilst retaining the same power output from the gearbox? The power HAS to go somewhere ;)
 
I always thought that LSDs on FWD cars were supposed to be rubbish but after merlin took me out in the Teg I was converted. The difference between that car and the CTR was night and day, his Teg felt much more like my Elise in the way that it handled, amazing for a FWD car!

Yeah into friction and thus heat in the brake disk.

As Paradigm says, some will, but as you know energy always takes the easiest path!

Can't say I'm a big fan of EDL, or ADB as BMW call it. Variable M differential lock is where it's at!
