Watch Rivian hand-assemble the R1T prototype

On Friday, Livian released a video giving a glimpse into the development process of the R1T electric pickup truck, which was originally scheduled to go into production later this year, but the company expects a delay due to the ongoing coronavirus pandemic.

The prototype uses the same components as the production version, but everything is assembled by hand in a dedicated factory rather than on a conventional assembly line. The prototypes are used for testing and, due to their hand-built nature, are likely to be broken down after they have served their purpose. Prototypes are used to test dynamics, winter temperatures, electronics, software, driver assistance systems, etc.

The R1T, like the R1S electric SUV, utilizes a "skateboard" platform built on box frame rails that houses all powertrain and mechanical components. This allows for easy loading of different vehicle bodies; in addition to the R1T and R1S, Rivian has also been contracted to build an electric van for Amazon and a Lincoln electric car on the same platform.

The R1T with the largest battery pack (180 kWh) has a range of 400 miles, Rivian claims. Rivian also claims 0-60 mph acceleration takes about 3.0 s, towing capacity is about 7,700 pounds, and payload capacity is 1,763 pounds.

The R1T also has several unusual features that take advantage of its electric drivetrain. With no engine or driveshaft, Rivian was able to give the truck a "sidewall" and a tunnel between the cab and bed for storing long items. Rivian also claims that the R1T (and R1S) can perform a "tank turn", turning 360 degrees on the spot.

Rivian plans to assemble the R1T and R1S, as well as unnamed Lincoln models, at the former Mitsubishi plant in Normal, Illinois. Rivian purchased this plant from Mitsubishi in 2016.
