Isn't this all just personal preference? if you want the extra power, you'd go with quad.. If you dont' need it and happy with lesser model, then by all means.

With that said, R1T is a heavy truck. I will still go for quad motor if it's an option. And I occassionally push the car.. and extra juice is nice to have.

If the price difference is 20k+, it's questionable, but as is now, I am fine.

It really comes down to personal preference and need.

Here are a few of my noteworthy reasons:

  • We do minimal overlanding and offroading so I have no huge benefit for the quad drive unit setup
  • I don't plan on doing any heavy towing, so again, no need
  • Much of our driving is highway and I would benefit for the slightly lighter vehicle with more range of the dual drive unit setup (hopefully conserve mode will still exist; that 320 could easily peak to 360-380)
  • Quad drive unit setup has twice the likelihood of unit failure
  • I also believe the existing drive units in the quad setup are older technology - the new enduro motors will (hopefully) be more efficient and reliable in the long run, over the existing tech.
Dual motor's range will be 260-280 With standard battery pack.

Rivian expanded Normal in part for Enduro production. Give me Bosch motors. I would also like a Bosch automatic tonneau and a Bosch kitchen. My existing all Bosch kitchen is excellent but not particuarly portable.

Bosch should also be great at developing a winch
Looks like we should be buying Bosch stock

Responding line by line:

"For example, if an enduro goes out you lose power to two wheels not one, so the equivalent of losing two motors."​

What you don't seem to realize is when an existing drive unit fails on an R1T or R1S, it kills power to the entire axle. We've seen this before; users have had a drive-unit failure in the front, and the Rivian software will also shut down power to the axle-paired side. So that point is moot.

"Also, new motors might be judged more likely to fail, being an all-new unproven design, verses a motor where 80,000 are functioning excellently in the wild (20,000 vehicles * 4 motors)."​

I have to disagree here. Rivian will be using technology in the new enduro motor that is more modern and bleeding-edge, meaning we will see many other companies and industries using similar electric motor technology. The same could be argued about the current motor used in the quad drive unit setup, however we know that technology is older and will be inherently less efficient. As technology becomes more developed, we know these few strategies hold true: make it more efficient, make it easier to manufacture, and manufacture it for less. Yes I'm sure the enduro motors will be cheaper to manufacturer from a labor perspective, but there will be more parts and materials involved to build the unit. Again, going back to using more bleeding-edge tech, versus legacy tech. Also, 80,000 units in production usage isn't a lot. We can rehash that comment when Rivian has 250,000-500,000 drive units actively being used.

"Also torque vectoring helps every time you make a turn, not just off-roading or towing."​

Torque vectoring is great when you're pushing the vehicle to it's limits around tight corners and banks in the road. I'm sure a marginal percentage of owners will be doing this - particularly the people like the owner who took their R1S to Summit Point. I don't plan on driving my Rivian in anything higher than a street-spirited fashion - torque vectoring is moot to me.
Moot is the word....

Does anyone know if Enduro is strictly for dual motor or will it be used in the quad variant as well? I know we are just speculating at this point but I am confused as to why Rivian sees inhouse motors as a priority over all the other things they are dealing with ( R2 design, production ramp, building thier next factory, service ramp, RAN etc). I get the desire to walk and chew gum but only if you aren't tripping all over the place.

Reason 1... Bosch probably has a nice markup/profit on the motors they sell to Rivian. Make the motors yourself and you save that markup $$$.
Reason 2... Rivian can build the motor exactly to spec and make changes much more quickly if they have 100% control over the design and manufacturing process.

Assuming lockers. Dual motors may just be some sort of limited slip setup. "For maximum performance in slippery conditions, choose quad motors". Traction in exssting dual motor EV is quite good, but not like quad motors or full lockers on ICE 4x4
