Rivian has discontinued the cheapest electric car option

Only a small percentage of customers chose the entry-level navigation configuration. The vehicles originally came with two packages — Adventure and Explore — and “most” chose the Adventure.

Customers who choose the Explore package save at least $5,500. The Adventure Package, which starts at $73,000, features a premium interior and Gear Guard remote control system and safety cables.

“By focusing on the Adventure trim package, we are able to streamline our supply chain and deliver vehicles faster,” Rivian said.

Rivian has a backlog of 100,000 orders, but it hasn’t been short of controversy lately. It laid off 6 percent of its workforce last month, citing inflation, high interest rates and rising commodity prices. And in March it scaled back price hikes on pre-ordered vehicles after a backlash from customers.

Something of a Wall Street darling, Rivian went public nine months ago at $78 a share, the largest IPO ever, and briefly traded above $100. It closed Friday at $34.45.

Customers who ordered the Explore option can still upgrade to the Adventure Package, cancel their pre-order or “do nothing,” Rivian said.

The package can be reconfigured online, and Rivian says it will estimate a new delivery window, noting that it won’t automatically result in an earlier date.

If customers don’t act by Sept. 1, Rivian said it will remove pre-orders of the Explorer package from the product queue until they update the configuration.

Customers who choose to cancel will receive a full refund by September 16.
