My buddy swapped vehicles with his other buddy who has a Rivian. His review:
* The advantages of the Rivian are (1) 4 motors, (2) better range, and (3) a spare tire
* However: (1) it's louder than the Cybertruck, (2) drove like a pickup truck, and (3) tech feels outdated inside
Performance-wise, the Rivian truck options are:
1. Dual-motor AWD: 4.5s (533hp)
2. Performance dual-motor AWD: 3.5s (665hp)
3. Quad-motor AWD: 3.0s (835hp)
Rivian battery options:
1. Standard: 270m
2. Standard Plus: 315m
3. Large: 352m
4. Max: 410m
For the Cybertruck:
1. RWD: 6.5s
2. AWD: 4.1s (600hp)
3. Cyberbeast: 2.6s (845hp)
Cybertruck battery options:
1. RWD: 250m
2. AWD: 340m
3. Cyberbeast: 320m
The Cybertruck also has a 120-mile add-on battery backpack for $16k, which apparently has a 25% take rate: (not sure if this is currently shipping or not)
It has to be professionally installed & eats up the bed space, however. It also weighs roughly 600 pounds & reduces the payload from 2,500 pounds to 1,900 pounds. For reference, the Rivian's payload capacity is 1,764 pounds & the F-150 Lightning's payload is 2,235 pounds. For comparison, as that article points out, you can buy a used Chevy Bolt EV for $16k lol. However, the extended battery takes the AWD model from 340 miles to 470 miles of range & the Cyberbeast from 320 miles to 440 miles of range. Note that ICE vehicles have "fuel backpacks" available as well: (either for fueling up other vehicles, or for range extension)
