Toyota will add two new V-6 engines to its production lineup, officially completing a $288 million expansion at its engine plant in Huntsville, Alabama. The project is expected to create 450 jobs.

The automaker’s total cumulative investment is $1.2 billion in the Huntsville facility, which now boasts an annual engine capacity of 900,000.

“Our team members in Alabama recognize the confidence and trust Toyota places in us since we are the only plant selected to build engines for the all-new Tundra,” said Jason Puckett, president of Toyota Alabama.“Launching the new twin-turbo V6 line and celebrating our 20th anniversary remind us here just how lucky we are to have such incredible team members who have made Toyota Alabama known as ‘the engine capital of the world’.”

According to the Alabama Department of Commerce, the twin-turbo V6 engine options for the 2022 Tundra are being built on the longest Toyota engine line in North America, at 142 yards. The V6 Turbo line will produce a new engine every 58 seconds, with a capacity to build 18,000 engines each month. The additional engines push the total capacity for Toyota Alabama engine production to up to 900,000 engines per year.

“For the last 20 years, our state and Toyota Motor Manufacturing Alabama have shared a mutually beneficial relationship that has created remarkable outcomes for Alabamians,” Governor Kay Ivey said.“Toyota’s $288 million investment to produce the all-new twin-turbo V6 engine continues to demonstrate that Alabama is not only open for business, but is the best place to do business,” she added.

Meanwhile, Toyota is teaming with Mazda to build a $2.3 billion joint venture assembly plant just miles away in another location in Huntsville. Production, split evenly between the partners, has begun with the 2022 Toyota Corolla Cross, with the Mazda CX-50 to debut in January. Mazda Toyota Manufacturing will employ 4,000 workers at full production.

“Toyota is a pillar in Alabama’s growing automotive manufacturing industry, and we have developed a special relationship with this first-class company over the years,” said Greg Canfield, Secretary of the Alabama Department of Commerce.
