When Rivian launched its much-delayed R1T electric pickup last fall, the reviews were breathless.
"The coolest pickup ever made," said auto enthusiast and popular YouTube presenter Doug DeMuro. "The most remarkable pickup truck we've ever driven," declared MotorTrend before naming it Truck of the Year.
More recently, the Amazon-backed startup has been on something of a roller-coaster ride, with last year's euphoria fading into fresh concerns over production targets and the departure of a top executive.
The company saw its market value soar after its November initial public offering, besting General Motors and Ford Motor Co., a key Rivian investor. In mid-December, Rivian announced a second factory, near Atlanta, that will increase the company's production capacity by 400,000 vehicles per year.
