Orion Assembly

Orion Assembly is a 4,300,000 sqft General Motors vehicle assembly plant located in Orion Township, Michigan. From late 2025, the plant is slated to assemble battery electric pickup trucks such as the Chevrolet Silverado EV and the GMC Sierra EV. As of September 2019, the plant has approximately 1,032 salaried and hourly employees. It assumed operations of Buick City, and Pontiac Assembly.

History
Orion Assembly commenced production on December 1, 1983 with the 1985 model C-body cars. Orion Assembly produced the Chevrolet Malibu and Pontiac G6 until 2009, when the plant was idled due to the General Motors Chapter 11 reorganization of 2009. The plant in suburban Detroit was saved from closure through a $1 billion grants and tax incentives from the state of Michigan, local municipalities and the federal government. Under an agreement with the UAW, the plant began assembling the successor to the South Korean-built Chevrolet Aveo, the Chevrolet Sonic, in 2011 &mdash; making it the only subcompact car currently assembled in America. Later in 2011, the plant began manufacturing the Buick Verano.

In the past, GM assembled subcompact vehicles in Mexico or in South Korea due to lower cost labor rates in those countries. Under the new agreement with the UAW, GM used domestic laborers earning less than under previous contracts and slimmed down labor rules to make assembling subcompact vehicles in the US economically competitive. For younger workers, wages were cut in half from the standard $28/hour. For the first time, parts supplier employees worked alongside of GM workers on the assembly line. They made as little as $10/hour. This arrangement replaced GM's previous plan to import a new subcompact vehicle from China. Orion's bid was selected over those from plants in Wisconsin (Janesville Assembly), and Tennessee (Spring Hill Assembly).

On March 22, 2019, GM announced an additional investment of $300 million and an addition of 400 workers to build a new electric vehicle at Orion. This was later revealed to be a slightly larger version of the Bolt to be known as the Bolt EUV.

In 2023, GM announced that it will discontinue the production of Chevrolet Bolt at the end of 2023, with that the Orion plant will be reopened as the Orion EV Assembly in 2024, to produce electric pickup trucks such as the Chevrolet Silverado EV and the GMC Sierra EV. With $4 billion in additional investment at the facility, GM CEO Mary Barra announced that "employment will nearly triple (from 2023) and we'll have a companywide capacity to build 600,000 electric trucks annually."

Controversy
After GM announced the plan to construct a new factory, opposition to the plant in Orion Township came from three separate groups: those who disliked the fact that GM had selected the site without first notifying township officials (a land option was previously given to Grand Trunk Railway by township officials without first informing the public, which then was negotiated for GM by Argonaut Realty); pilots who opposed its location on land which was at the time partially occupied by the Oakland-Pontiac Airport; and from the community group Area Citizens for a Rural Environment (ACRE) who opposed the factory over environmental concerns. GM instated a community relations campaign in Orion Township to garner support. While groundbreaking was intended to happen in June, the construction of the factory was briefly delayed by an ACRE referendum opposing the construction of the factory, which gathered enough signatures to be placed on the ballot. At the August 6, 1980 election in Orion Township, the construction of the plant was approved by 90% of voters, and groundbreaking took place shortly after.

Dedication ceremony
On July 5, 1984, President Ronald Reagan gave a ceremonial dedication speech at the plant. Also in attendance were Michigan Governor James Blanchard, Michigan Senators Carl Levin and Don Riegle, Representative (from the local district) William Broomfield and notable General Motors executives, including chairman and CEO Roger Smith.

During his speech, Reagan commended both GM and the United Auto Workers for their progress in the automotive industry.
