The R1T truck model by Rivian was spotted in South Argentina doing some tests. The vehicles registered had new different colors, and basic features that looked different from models that have been previously exhibited.
So far, the concept models of the electric vehicles were only shown in a shiny grey. However, the new pictures revealed the truck in a dark grey version and a white version. Both of them look really dirty, which is something to expect from a pickup truck. The dirt covering the truck does look like it suits the car.
Other features, such as the charge port, were placed in different spots. According to Rivian even though these are the models being tested, the production vehicle will probably look like the concept instead of the ones in the pictures. The company stated that in response to a post on Electrek.
