    R1T Gen 1 Quad Large vs. Gen 2 Dual Max Pack: Efficiency and Charging Analysis

    Summary: drive 100 mph at all times, unless there is some slow guy in front of you. Then use the shoulder to pass at 100 mph.

    R1T Gen 1 Quad Large vs. Gen 2 Dual Max Pack: Efficiency and Charging Analysis

    The Max Pack usable capacity is 141 kWh. The Silverado usable capacity is 204 kWh. The difference is 63 kWh, but that isn't the reason the Silverado has a higher charging speed. The Silverado takes the 400V battery pack and allows higher voltage chargers to charge it at 800V, by putting half...

    Brutal Vampire Drain

    @Gologic - please let us know what happened with your Gen2 Tri. Was it dead when you got back to the airport? I can't believe this has come up with the Gen2. I believed the marketing material claiming the "lowest vampire drain in the industry", or something to that effect. It is a big reason I...

    Extension cable to use Tesla V3 superchargers?

    Picture! This isn't a bad option if there is room to do it. Why drive a R1 if you can't drive over stuff?

    Rivan #1 brand for Owner Satisfaction in Consumer Reports survey

    Interesting Lucid is not in the list. Maybe their production volumes are too low. I bet they would be fighting for last place with Rivian. And that is really too bad, because Rivian and Lucid are my two favorite car brands now. Sigh.

    12v Lead Acid Battery Replacement

    Why are you recommending this? Did you do the replacement, and can you confirm it works well over multiple seasons? If you have, please share that information. If you just have Ohmmu marketing material, it is not convincing to me. I would stick with a factory compatible AGM battery. A 12V...

    R1T Gen 1 Quad Large vs. Gen 2 Dual Max Pack: Efficiency and Charging Analysis

    Rick, you are amazing. I love this post. I am surprised the heat pump is not making a measurable difference in cold temperatures. I wonder if you will see a trend after you get more data points. That said, I think the difference is likely to be less than 10%, so considering all the other...

    Out of Spec 10% Challenge of Gen2 R1T dual Max: Massively Negative!

    So, not trying to stir up an old subject, but I am wondering if you think he just has a friend at Rivian that hooked him up. I can see that happening. And while frustrating because he skipped the line, it is not unusual to leverage a relationship. I would do it. And if it happened Iike that, it...

    Rivian Gets $6.6B DOE Loan Commitment for Georgia Plant Construction

    If the government is taking money from you and then giving it back to you, why wouldn't you take it? It is better if they didn't take it from you in the first place, but they do. Personally, I don't see apposing that process as hypocrisy when it is the law, and we are forced to participate in...

    Rivian Gets $6.6B DOE Loan Commitment for Georgia Plant Construction

    Thanks Donald. This is a very reasonable position, and reminds me of the famous quote from James Madison: "If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary. In framing a government which...

    20" Inch High efficiency 20" wheels and ~34" tires options (R20 - 285/60 - 275/65 - 285/65 - 295/65)

    I am not ignoring it, I just think it isn't as significant as the tire compound and rim aerodynamics. But as I said, it is just my theory (based on the studies I have read regarding wheel efficiency).

    Rivian Gets $6.6B DOE Loan Commitment for Georgia Plant Construction

    The government bailouts of GM and Chrysler were illegal, IMO, and never should have happened. More bad spending isn't a compelling argument to me.

    Rivian Gets $6.6B DOE Loan Commitment for Georgia Plant Construction

    I understand what you are saying. You are pointing out the truth about our markets. While I believe in free markets, I am not a anarchist. I just think smaller is better. Not zero, but very, very small. And we do have lots of data that shows government regulations and taxes depresses the...

    Rivian Gets $6.6B DOE Loan Commitment for Georgia Plant Construction

    I am sorry you feel that way. I am a huge Rivian fan and plan to buy a Tri Max sometime next year. And I do own RIVN stock. I bought right after the IPO. Whoops.

    Rivian Gets $6.6B DOE Loan Commitment for Georgia Plant Construction

    The cash that is given to them that they have to pay back comes from the taxpayers and adds to our debt. If Rivian pays it back, eventually the debt will be removed. However, until then, we have a bigger hole to fill. And what if Rivian goes bankrupt? Then what happens to the debt they owe? The...

    Rivian Gets $6.6B DOE Loan Commitment for Georgia Plant Construction

    That is not what is happening. It isn't opposition to high tech, highly-skilled manufacturing. It is opposition to government manipulating the free market. It is opposition to taking money from those who cannot afford to buy a Rivian and giving it to Rivian to build what they cannot buy. It is...

    Prediction: worse aerodynamics and higher rolling resistance will mean a measurable hit on efficiency. Let us know what you see! And better yet, post some pictures!

    Out of Spec 10% Challenge of Gen2 R1T dual Max: Massively Negative!

    As someone who has only lived with one BEV (my Mach-e), this is totally livable. In fact, it is similar to what I see in my car which has a much smaller battery. And 75% of 141 kWh is a lot better than 75% of 91 kWh. Faster charging is better, of course. But for every single time I have needed...

    I'll celebrate when it gets back to $115. :oops:
