CR & JDPower will always be criticized because of their methods.
I've never met a CR subscriber. Have you? But I've also never met a Nielsen family. I watch whatever TV shows that I want, including ones that get cancelled after 1 Season :) And if you ever watch Family Feud, you'll know that...
I'm just a layperson who, like @Probity , may have been able to work some of these equations 20+ years ago in college. Nowadays it's just spitballing.
Sure, there is tweaking of aero. My guess would be the same as yours: car bodies that deflect better at 75mph than 65mph, and modern 8/9 speed...
There's the power equation without force F -- so just its proportionality equation.
Guilty.
Overheard in hallway: "I can drive faster AND save on gas!"
Me: "Whatever makes you sleep better, bless your heart"
You (and I) already said that a Watt is a unit of power. And a Joule is a unit of energy. We agree again. You are now using another equation, which does NOT say Watt is energy; it says Watt is a rate unit of energy. I already said it could be a rate of transfer. And I already said we...
I know that already. I'm giving an extreme example. The example could also be flipped to a 2000# trailer with just the driver + gas and nothing else.
What is your point? Because my point was to give an example of how the GCWR doesn't mean max tow + max payload, which is what we're here...
Nobody else mentioned that tach. If it's even a "tach". It's really an analog power meter. You have a point, but ...
... maybe a kw meter in dash is the future. Even if all-EV doesn't happen by 2030, a kw meter means every car driver will know power at that time. I think it's useful. In...
Oh boy, the great MPG debate. I'm drooling from all the misinformation! :) "New cars are so aero tuned that I can get higher MPG @ higher speed", etc. Hogwash!
Drag coefficient, Reynold's #s, 8+ gears, GDI fuel injection, blah blah blah. Let's do the Time Warp again!
A car (of mass)...
150# Americans? Only manufacturers (and the SAE) think that. More like 250#. 1 ton American family of 4.
I don't need to pass these F150s. Usually they pass ME because they're also going well above the speed limit. Overweight & speeding :eek:
Yesterday, I parked next to one of these (not...
Hah, yea when I saw that marketing pic by Ford I kinda chuckled. The Lances aren't known for being light but great 4 season campers. They also have large capacities (holding tanks, generators, etc.)
Which model are you thinking? My friend tows a Lance with his Z71. I think they have a 1900...
Sure, if someone puts 1516# on the truck. Will you be packing that much?
I'm not close to packing that much. 2 European sized people (aka. 150#/person), 2 pups (150#), 2 bikes (50#), beer cooler (50#), 2 backpacks (100#) + trailer tongue (200#) = 850# payload
That leaves 1486# for trailer.
Yup. I saw this same setup awhile ago from another Youtube video with a driver who put the Escape Hybrid into Sport, Eco, & Normal Drive modes. Same outcome: tach shows eMotor Kw output briefly spike at 1st, ICE quickly takes over as bulk power output, then eMotor comes back with a few kW...
Touche. I totally agree it's nit picky, and that's precisely why I mentioned it to you. Why even post a reply attempting to correct @WesM without showing the equations & their definitions? It didn't matter. So your nit picking his attempt to figure this out is why I nit picked on your reply...
I donated all my physics book but I never liked this oversimplification of Watts as energy over time.
Watt is a unit of power. Watt-hour is rate of power.
Power is work over time. Power is not energy over time.
The equation I had for exams was very simply: dP=dW/dt, as a derivative. The...
Of course it will be. I've been just as curious about the actual torque # but calculating anything looked like speculation.
Where is the # coming from?
fbov or someone linked an article awhile back that quote Ford engineers saying the new HF45+ emotor generates 2,300Nm torque / 98 kW power...
Hey, that guy looks familiar! :D
That Alto Blue looks dark when inside. Makes me 2nd guess my color. But outside or when sunlight hits it does look brighter.
