The Rivian-made electric delivery vans are being used by Amazon. The retail giant has made more than five million deliveries in the US with its new zero-tailpipe emission vehicles.

The company has 30,000 Amazon- branded delivery vehicles and 20,000 branded trailers. Rivian expects to deliver 100,000 vans by the end of the year.

That is only a small part of the company's transportation fleet.

The EDVs began in Baltimore, Chicago, Dallas, Nashville, San Diego, and Seattle. They've been put into service in a number of new cities, including Austin, Boston, Denver, Houston, Indianapolis, Las Vegas, Madison, Newark, New York, Oakland, Pittsburgh, Portland, and Salt Lake City.

The vans are making their way into Amazon. During the three-month period that ended on September 30, the EV company made 7,363 R1T pickup trucks, R1S SUVs, and EDVs. Rivian delivered 6,584 vehicles during the same period. The company is expected to report its results later this week.

Supply chain troubles and inflation are just some of the hurdles that have hampered Amazon and Rivian's goal of an electric delivery fleet. When Jeff Bezos announced a deal with the EV startup to buy 100,000 vans, he said they should be on the road in four years. 100,000 vans will be on the road by the year 2030.

Udit Madan, vice president of Amazon transportation, said that making deliveries to customers across the country with their new zero emission vehicles for the first time makes this year unique. Over 5 million packages have been delivered with our vehicles produced by Rivian, and this is just the beginning, as we continue to make progress towards our 100,000-vehicle goal.
