Rivian

The world’s largest retailer Amazon has signed on to buy 100,000 of Rivian's zero-emission trucks as part of a wider push to clean up its business operations.

Overlanding in an electric vehicle, meandering miles off the electrical grid for days, has so far been virtually unfathomable. But electric truck startup Rivian is hoping to make it more mainstream. Its electric pickup camper has 400 miles (644 km) of range, a roof-top tent and an electric kitchen.
