Standard pressure at 5,000/standard pressure at SL. 12.2/14.7=.83

Although the power output from the motors is not impacted, the ability of the thinner air to cool components is reduced. You have less airflow over those components that need to be cooled.

I would have expected them to really push it. Like 15,000 pounds, and/or 70mph. A good testing program will find the limits of a vehicle.

Harley Davidson still trying to remain relevant, but they really are a company that needs to die. It is a nice looking bike, but I just would never buy from a company with Harley Davidsons poor reliability & quality reputation.

The reason why an ICE appears to do better when towing is because of the power to maintain combustion. For example, if the vehicle uses 1 gallon per hour at idle, that 1 GPH provide no useful work, but is always required when the vehicle is under power. If you are going 60MPH and using 3 GPH...

You get better mileage in the mountains because of reduced air resistance, not because of the hills. You might get a slightly lower BSFC at a higher power setting, but it would be minimal.

They routinely call it an adventure vehicle. A vehicle for people who spend their time outdoors, with dogs, and get dirty. I am just not seeing that with the Rivian.

Rivian keeps losing me more and more with every press release. They really have not defined their audience well. People who want an adventure vehicle don't want to waste money on a plush interior. People who want luxury galore probably aren't gonna go off-roading. Like I think thick canvas...

I didn't say regen would stop your rig, but it would slow it down, or maintain speed, even on the steepest hills. The motors can produce a significant force at speed and could easily slow or maintain the speed of your rig down a slope while throwing a lot of energy into the batteries. As you...

It is CappyJax. And the resistance will not change with regen on or off until you step on the brake pedal and engage the regen. Then the Rivian will apply regenerative braking and charge the batteries. It only works when the brakes are engaged. What that means is that it can slow down both...

It will have a lot of autonomous features. So, a break-away would probably result in it pulling over and stopping. I don't understand why you would want to turn off regeneration. It would reduce the wear and tear on the RV and Rivian, and it would be collecting free energy. It would only be...

I am not sure which ones are actual colors seen on Rivian vehicles, or just concepts by fans.

It is about 70 pounds more than a friction hitch with bars. My Transit 250 van rides perfectly level ones I cinch up the bars.

You might have had your audio off, but the first thing he says in the video is "I am attaching a weight distribution hitch." A lot of people think you don't need a weight distribution hitch with leveling airbags, but that is not true at all. Leveling the vehicle does almost nothing for...

I want an interior I can spray down with a hose. ;)

3,300Wh/kg over 5,730 years. So, in 52,000,000 hours you get 3,300Wh/kg. That comes our to 63µW of power per kg.

I like this color too.

This is the only color I have seen that I like so far. But I am really hoping for a burnt copper color.

Because I tend to keep vehicles a long time 10+ years, I am always looking for longevity. With BEV's, having the largest battery will allow for the least stress on the battery. If I have 400 miles of range, but recharge after 200 miles, that is much less stress on the pack than if I am going...

Because the efficiency of motors mostly increases as power increases. So, using this chart and referencing the red line, if you have 4 motors each putting out 200W, you have around 79% efficiency. If you turn two off and you have the other two motors each putting out 400W, then you have 85%...
