RX330 last thing it's designed for is off roading lol.

 

Actually, Cybertruck body is going to be extremely hard to scratch and damage.

​​​​​​It is not your fridge.

But it will keep plenty of greasy fingertips.

 

It was on my Facebook but I just lost it...

CT went 254 miles in 46 degree weather on a flat steady cruise on the highway. Apparently it's rated for 320?

And don't shoot the messenger.

 

it was posted here few pages back, as it happened. Looks like a good efficiency.

 

The mileage rating you see for an EV is based on mixed or mostly city driving where the regenerative braking helps recharge the battery. I get about 70% of the stated range on my Model Y with highway driving because I'm going 80-85mph and there is no opportunity for regen braking. I think in my case that's somewhere around 210 miles, although I don't really know because I've only taken it on 2 trips of 3+ hours. I just use it for our daily around town driving.

 

320 is blended and assumes 55% highway and 45% city, so 254 is entirely reasonable. The other thing is that the specific speed of the cybertuck is an important detail as efficiency will decrease dramatically as speed increases (because aerodynamic drag has a bigger impact on bigger vehicles like cybertruck and drag is proportional to the square of speed, so the there’s a relatively bigger impact as speed increases )

 

Based on some rough calculations I've done, I'm averaging 260 miles, that's with mixed driving, highway I'm averaging 75 mph. Today the temps were 34 degrees F in SJ, and I lost about 4 percent to heating/defrosting

 

the 'ratings' for ev's need revising to show both the city/mixed expectation AND the highway expectation.
they're very misleading and people buy ev's based off the rating info they see.

 

I totally agree. But than that may just scare people off, so it's a catch 22

 

They're really no more and no less misleading than the EPA ratings for ICE cars which work the exact same way and have their own issues in that how close you get to the EPA number is 100% contingent upon how close your driving mix is to the baselines.

 

highway in EPA test is also something like 45 mph on average.

If 255 was the same for everyone, it would be good numbers. I think depending on roads, average speed, tweather, load, etc, some people will be getting closer to 200 and they might be quite happy with it.

 

scaring people off with the truth? and that's bad?

while that's true the big difference is ice driving doesn't give results dramatically worse when driving at normal highway speeds.

 

^ Agreed. Efficiency difference on my Ody between 70 and 85 is negligible. Same speeds on the R1S are very noticeable

 

Most people aren’t measuring or seeing the differences with their ICE cars because they don’t focus on range so much plus the data might not be as accessible but the physics doesn’t change. Aerodynamic drag still rises with the square of speed and the drag delta between 70 to 85 is greater than the speed delta between 70 and 85. The calculation is of course impacted by drag coefficient and frontal area and on some vehicles that’s going to be more noticeable than others. Atmospheric conditions too, driving into a headwind or driving with a tailwind will deliver different efficiency at constant speed. Obviously there’s the impact of the transmission in the case of the ICE vehicle. You can cruise at speed at relatively low RPM. But you’re still using more fuel as speed increases.

 

Impact of speed increases is less pronounced on ICE vs. EV though. I'll lose maybe half an MPG going from cruising at 70 to 80 in the ody, but my range hit doing the same thing in the R1S will be more drastic
