The H3 boundary: the Hummer Mishawaka never built

The exact page text, read by your browser's voice.

2005 – 2010

The boundary printed plainly: The third Hummer was not a Mishawaka vehicle in any part. The H3 was General Motors' own design on GM's own midsize platform, and it was built by General Motors at its Shreveport, Louisiana plant from April 2005 to 24 May 2010 — with additional assembly at Port Elizabeth, South Africa, and Kaliningrad, Russia — and its pickup derivative, the H3T, likewise at Shreveport. AM General designed none of it and built none of it. The entry exists because the H3 is where a careless telling of the GM chapter goes wrong: the brand's volume peak was Shreveport's, not Mishawaka's.

Two peaks, kept separate: The marque archive's reconciled United States sales table shows the brand's shape: 29,345 sold in 2004, then 56,727 in 2005 — of which the H3, launched that April, was 33,140 — and a peak of 71,524 in 2006, of which the H3 was 54,052 and the Mishawaka-built H2 17,107. Mishawaka's own peak and the brand's peak were different events in different states, and the Mishawaka record's GM chapter is the smaller, truer one: two plants, two models, and a contract, all of it ended by 2009.
