Bit of a strange question I know but in the MX-5 I can feel a bit of a sensation when accelerating out of a tight bend? It's not nearly enough to provoke a slide or for the TC light to come but I can definitely feel something reigning the power in. My only explanation is the LSD doing it's thing but having never had a car with one before I'm not too sure.

In response to your question I have never driven an RWD car with out an LSD so wouldn't know what the contrast would be like but it essentialy it makes both rear wheels mimic each others speed, I've driven an R26 F1 team edition Megane which has an LSD it's obviously FWD but an LSD in a FWD car feels like it pulls you tighter around the corner when you apply the power from the apex progressively out of the corner.

Hope that makes sense/helps thumbup

An LSD wouldn't reign in the power. Fuel surge?

It doesn't reign in the power so you are not feeling that.

Comparing chalk and cheese here but I have two RWD cars one with (Elise) the other without (300CE). The difference can certainly be felt exiting a slippery junction. The 300CE just wants to spin up the inside wheel and will waste the power doing so going nowhere fast. The Elise has more grip in this scenario and even if provoked into a powerslide still keeps decent drive forward.

Recently drove the Elise on some very slippery back roads (black ice eek) early one morning. Breathing on the throttle in third was spinning the wheels and I could feel the diff hooking up and the backend stepping out a tad! Bit more exciting than I wanted so I went home biggrin

So yes I can feel it in action.

More likely the traction control on the 5.

You sure it's not just the difference between FWD and RWD? Making assumptions from your garage, would I be wrong in thinking the MX5 is your first RWD car?

sounds like a version of dynamic stability control in use using the abs and brakes to correct instability by braking wheels likely to lose traction rather than cutting power?
As for the LSD yes you can feel it !

My old MR2 Turbo had a LSD, you could feel coming out of bends. Its hard to explain, not so much about grip, more the way the car drove out of the bend, they way you feel it prevent the inner out outer wheel losing power and instead ejecting you out of the bend.

With some of the more, er, agricultural LSD's you can hear them as well as feel them in action (mainly the "Plate" types)

Yeah my MR2 Mk2 made a little 'clonk' when the LSD kicked in. You could feel it like hitting a little bump in the road.

I remember reading in an old Cars and Car Conversions mag about a racing Mustang.
It had a locker diff so if one wheel spun a few turns it locked solid until you came off of the power.
That owner said he had a photo of him pulling hard out of a bend with one rear wheel in the air and the other one leaving a black line.
Always wanted to see that photo. smokin
Yes, you can feel the LSD. It makes a huge difference.

The effect of the LSD engaging in a Megane R26 is as if a giant hand has got hold of your vehicle and pulled it firmly towards the apex. It's quite addictive.
