Following a series of delays, the highly anticipated Rivian R1T has finally gone into production.

In a tweet, CEO RJ Scaringe marked the milestone as he said the “first customer vehicle drove off our production line in Normal, [Illinois].” The executive went on to praise his employees and say he “can’t wait to get these into the hands of our customers!”

The moment has been years in the making as the R1T originally debuted at the 2018 Los Angeles Auto Show and was slated to be launched in 2020. Of course, that didn’t happen as the coronavirus threw a wrench in the company’s plan and the model was delayed multiple times for a variety of issues including final approval by government agencies.
