I believe those are for aligning pins.

This type of post is Jason's bread and butter!

I think you missed the joke

Prius doesn't use lithium....

You are magnificent

stopped reading at "Modern cars... have all 500 ponies available from a tick over idle"

Thank you!! It seems like the tricky part would be proving that they didn't do such a study, but I look forward into investigating more deeply.

Please tell me where I can learn more about this. If there's any validity, I would be a very happy guy.

dingdingdingggg I get just as much enjoyment out of blasting around town on a hopped-up moped (with pedals) than I do driving my turbo e30, karting, or doing autocross. All are great fun, just different kinds! :D

I was referring to the fact that a spoiler has a mass all on its own :p

Goodness, if I wanted to make you look bad I would have pointed out how you used "you're" incorrectly twice in your original post, but I didn't do that because correcting your grammar would be nitpicking and pointless in an article about physics.

It's a really simple disagreement about whether it's 50% or 70%. He keeps saying 50%, and posts an image that shows 70%. So, am I supposed to say "hey your numbers are wrong but let's just go ahead and pretend that cars don't do what they do?"

Yeah I realized I sounded like a jerk after I posted. I typed 90% of my reply right after your original post, left for a couple hours, came back and finished typing it and submitted before I reloaded the page to see the other replies.

Objectively, Mazda is killing it with internal combustion development. You want 14:1 compression ratio in an economy car? YOU GOT IT, THANKS MAZDA.

I'm not picking nits.

I think you need to go back and re-read that vehicle dynamics book. Sway bar stiffness is much more important when it's a comparison of front:rear stiffness balance and in transitions. Once in steady-state, weaker overall roll stiffness only contributes to weight transfer by the additional movement of the mass center,…

Sorry, but it's not 50%, it's 71% (assuming it's a friction circle and not an ellipse). The key is that the overall vector is represented by the radius. It's trig, not simple arithmetic.

"Only about half as good..."

2) Most materials on most materials have a coefficient of friction of less that 1. But rubber on asphalt makes an awesome match for transportation, and routinely registers a coefficient of friction within 5% of 1.0. If you manage to increase the coefficient of friction above 1.0 you can accelerate horizontally even…

Oh goodness thank you!!!!!!!
