"News of our economic success seems to be a daily occurrence", she said.
Toyota plans to build Corolla cars at the plant, while Mazda will build crossover SUVs.
The State of Alabama is the fifth largest producer of cars and light trucks nationally with a strong automotive manufacturing presence including Toyota's engine plant in Huntsville, where Toyota employs 1,400 team members.
The companies announced they would build a new plant at an undetermined location in August past year under a capital tie-up and almost 20 USA states sought to land the facility.
Alabama was tied with Tennessee as the fifth-largest producer of vehicles in the country previous year, according to the Center for Automotive Research, an industry think tank in Ann Arbor, Michigan.
"The partnership between Toyota and Mazda will expand innovative automotive manufacturing in Alabama", Governor Ivey said.
And Toyota has an engine plant in the Huntsville area, near where it is planning to put the new facility. The facility is expected to create up to 4,000 jobs. USA new vehicle sales fell 2 percent in 2017, after hitting a record high in 2016, and are expected to fall further in 2018.
Toyota and Mazda plan to equally split the cost of the plant, which will build Toyota Corollas and a new small SUV from Mazda.
Toyota and Mazda Motor Corp. also plan to work together on various advanced auto technology, such as electric vehicles, safety features and connected cars, as well as products that they could supply each other, they said.
If Wednesday afternoon's announcement wasn't official enough, it's now received the President Trump tweet stamp of approval.
The decision - a boon for President Donald Trump's drive to bring investment and jobs to the country - was made based on the state's efficient logistics network and concentration of auto parts makers, among other factors.
Lentz said it makes sense to build Corollas because Toyota needs the volume even in a declining auto market.
In October, Toyota said it would scale back investment in a planned plant in Mexico by 30 percent to $700 million and cut planned annual capacity in half to 100,000 vehicles as it shuffles its production plans to meet market demands. With more than 150 Tier 1 and 2 automotive suppliers in the state as well as automakers, there are approximately 57,000 automotive manufacturing jobs in Alabama.
Mazda began selling vehicles in North America 50 years ago, this year, with the establishment of affiliate companies in Canada (Mazda Canada, Inc.) in 1968, in the United States (Mazda Motor of America, d/b/a Mazda North American Operations) in 1970, and in Mexico (Mazda Motor de Mexico) in 2006. Southern U.S. states have the advantage of good transportation infrastructure, business-friendly regulators and generally anti-union politicians.
