And it should be noted that since Teslas are single-speed, the resulting acceleration sort of matches the torque curve, except it tapers off exponentially more strongly as speed increases due to aerodynamic drag - a point that was made exceedingly clear to me when I raced my turbo e30 against a Tesla Roadster. They…
“However, at any given engine speed, the accelerating force is proportional to the torque.” See, you’re missing a key factor here - the gearing. At a given engine speed, the accelerating force is proportional to the torque multiplied by the gear ratio divided by the tire radius. I can consider two engines in that…
So you’re saying most vehicles can’t operate near their power peaks by downshifting? And that the power available around the peak is not spread wide enough to cover modern transmissions with 6 or more gears? Most engines make 90%+ of peak power within rev ranges that their transmissions can keep the engine. It doesn’t…
(also, he never talked about “intervals,” and power is not how much work the engine can do. If you consider how long that power is applied, then you know how much work the engine can do, but power by itself does not tell you that)
Torque is not a force. A force is a force. Torque is therefore not a force, because it’s a force applied with a lever arm to cause something to rotate. Power = force * velocity, therefore all else held equal, the car with the most power available in a given situation will accelerate harder, because a greater force…
Tesla motors don’t deliver full torque over the full speed range, though. They deliver full power for most of the speed range, which is exactly my point:
I love when real data comes in response to nonsense articles - I think that’s where real innovation takes place (like, I think the Big Mac index was originally supposed to be a joke, but we learned it in my econ class last semester). With a good “oil” thermostat, I bet you could make cheese work.
“You can have four figure HP, but without much torque you won’t get moving.” No, you can still get moving. If you can’t get moving, you don’t have 4-figure power when you’re trying to get moving. Either slip the clutch or downshift. Torque is irrelevant.
Yeah, except... most modern engines don’t “come on the cam” anymore. They have variable valve timing and lift and super high compression, and/or turbos that spool faster than diesels. My 1987 2-valve BMW engine “comes on the cam” but anything from the 1990s onwards basically doesn’t. If you’re waiting for it to come…
The video absolutely tries to substantiate the contrived notions that OP is complaining about. As awesome as Randy is, what he says in the video (as well as what is said in the article) is demonstrably incorrect and super misleading. While kaisersoze is ranting, they are 100% correct. Power available to you at a given…
Oof, not this again.
This is pretty darn good, and a novel perspective!
In other words, more of the same is coming?
Thank you for this! I have a feeling I will be listening to this for a while.
“Experience has shown me that 9/10 white dudes (or all people) don’t know what they’re talking about.”
I come from a mechanical/automotive engineering background. There’s still work to be done there for sure. My extremely limited anecdotal sample size indicates that your field seems to be doing better, so both of our experiences make sense to me. Hopefully the rest of the STEM fields can keep progressing.
