Handling terms: how to identify what’s happening when you corner

- If you can describe what your car is doing wrong in its handling, you can fix it. Understeer, oversteer, power steer, steady-state balance, bump steer, roll linearity and twitchiness. Buy the book now at www.amazon.com... or Amazon in your country.
That feeling when you finally balance out the car and get all 4 tires begin to lose grip concurrently (like in a steady turn like a freeway on-ramp). Heck, I got excited the first time my car oversteered at autocross coming out the slalom, it was exciting because it took several small changes and a couple years to get to that point with a 1st gen Chevy Cruze.
Awesome presentation. Thank you!
Thank you too!
@@JulianEdgarplease Julian, make a video about tire pressure and What is their influence in different scenario..
Great information, Julian. I just purchased your Car Suspension book hoping to learn more about the history of suspension design. Keep it coming!
Thank you. Don't forget to leave a written review on Amazon if you like it - it's one of the few ways a self-published author can promote their books.
Damn, these videos are good
I had a 2004 (BMW) Mini Cooper S that had flogged front arm bushes which caused bump understeer. Coming around a corner reasonably quickly and hit a bump and the whole car jumped nearly half a meter into the kerb. Scared the life out of me! It did mean I "had" to upgrade to new Enkei wheels though (Look. These ones are cheaper than the factory ones and look way better).
sounds like an Evo RS model you drove. they had a 2.1turn lock to lock steering rack for rally homologation, that would make it feel too sharp on the road
Evo 6.5 Tommi Makinen, from memory.
Excellent video!
Glad you liked it!
My car has the tendency to abruptly oversteer when i drive kinda fast on mediocre pavements mid and out of the corners. It's a mitsubishi colt 2011, so i guess it's because of the rear axle torsion beam. It feels kinda spooky and not confidence inspiring. Also some times, through motorway bends if going in fast, has that sudden roll and then it settles.
Get a new car, sounds like a death trap
My 370Z (completely stock, only 30,000km) had the characteristics of bump-steer even on straight roads if it hit uneven pavement at decent speed >120kmh or so. It felt like the rear was steering itself but also floating in what seemed like a quite underdamped fashion. It was the opposite of confidence-inspiring.. would that be down to the same cause as bump-steer in cornering? I can't say I recall it bump-steering awfully in corners so perhaps not.
I thought the same of the '19 370z I had a few years ago. Any imperfection in the road seemed to just throw the rear around. Random brown pant moments on the way to work didn't seem right
As a journalist, I test drove the then new 350Z. Terrible suspension.
@@JulianEdgarwow. I was always under the impression that 350z’s had decent handling. Maybe that’s why kids crash em these days
@@JulianEdgar What part of it in particular was bad?
Handled on the road like car set up for a smooth race track.
The other day I was in the traffic, waiting for the green light. As usual, I was observing the car in front of me. A modern Mercedes Benz SUV had rear spoiler and side skirts to reduce the wake. I noticed, there was a lot of dust on the side skirts ahewd of the flow separation edges. I was confused, how could Mercedes engineers fail at basic aerodynamics? I then noticed fake exhaust tips😮. It turned out it wasn't a Mercedes, but one of those chinese cars. Clearly, chinese care about aesthetics, but not so much about actual engineering.
most of them are fake
Not most people either. People that buy cars like that deserve public transport. I wish the car scene was dominated by car enthusiasts like it used to be back in the day. Mass adoption of cars was a fatal societal mistake. It should've just been kept to enthusiasts.
