This looks really cool, and is probably the most promising non-Tesla EV to date. But I'm a little worried it may not be able to achieve the promised range, and the bed looks really short to me, which seems like it will limit this truck to light-duty use.
Aerodynamics and low rolling resistance are crucial in achieving good range, but this truck has huge tires, a very high clearance, and an oddly flat nose, all of which seem like bad things for range. The four independent motors are also likely to be less efficient than one or two motors would be, though it remains to be seen exactly what motor tech Rivian is using.
They can compensate for this by making the battery bigger, but a bigger battery will make the truck significantly heavier and more expensive to manufacture, not to mention slower to charge.
There's also the question of charging and maintenance infrastructure — Rivian doesn't have any service centers or access to a fast charging network like Tesla's super chargers, so they've got some big challenges ahead of them.
I'd like to see it succeed though! It certainly seems like Rivian has a better chance than any other EV startup in recent memory.
