An e-diff is a computer-controlled limited slip differential, activated by a high-speed servo motor. After looking at inputs like the steering wheel position and the cornering load, yaw rate of the body and throttle position, the e-diff distributes drive left and right to maximise traction and increase cornering performance.
The result is more traction, increased yaw rate (less understeer) and you can get on the throttle earlier in the cornering process in extreme driving situations - such as on a racetrack. Earlier throttle application makes the car faster on the next straight and slashes lap time, obviously.
It takes a while to adapt to an e-diff on a track - initially you feel as if you are getting on the gas unreasonably early in the cornering process. When you get used to it, however, you'll see your lap times tumble...
John, I love these kind of technical subjects. Bring them on, please. Can’t wait.
Gave a thumbs up just for that definition of weight force vs mass - never heard it worded better.
Lucky for some of us aged folk to have someone to explain modern car Tech to us John, I'm ok with the old stuff but have definitely slipped behind with this new gubbins. Thank you.
John. I always love the beer garden and explanations you offer. It’s great to hear you talking about a car you love so much too. Makes me want to test drive an i30N. Keep it up mate.
Love learning about these technical matters from an intuitive and comprehensive presentation :)
Ditto John. Great tech. That drift was a beauty.
John, awesome breakdown of the aspects of the e-diff!!👍
Far be it for me to blow smoke at you John, but even as a long time viewer/reader it still strikes me as nice to have someone who is immune to the lure of car company junkets and tells it like it is and someone who actually understands how cars and the industry works. I always enjoy the tech videos. And we have an N Fastback in the family (just hit 1500km) and it's fkn awesome. Can't wait for the review.
Great video! Really love the analogies, description and presentation in general!
Datsun used to amaze me with their indepent braking set-ups on their rally 1600s. Thanks for the tutorial prof - always good /grateful to have punters understanding of these complex systems. Thanks for doing that. Amazed you can get an e-diff on a production Hyundai.
yes please john,love how you explain how new gadgets on cars work,cheers
Understanding comes with good explanation. You did that and I learnt something that I never really understood.
wow you killed this demonstration! Amazing job sir ! God bless you and keep up the good work :)
Great explanation on a complex subject John.
Great video JC. My insomnia was really getting out of hand but this cleared it right up
Just one word FANTASTIC!
Great video! Keen to watch more videos like this.
love the tech details JC!
Excellent - really enjoyed your discussion and explanation.
John I always enjoy these technical reports and would love to see them appear regularly.
