(HUNSTVILLE, AL) Edmunds AutoObserver -Reflecting an industry-wide shift to smaller-displacement engines, Toyota Motor Manufacturing Alabama Inc. said today the facility initiated production of 4-cylinder engines at the plant in Huntsville, AL. The TMMAL site, which also marked its 10-year anniversary this week, already produced V6s and V8s-and with the addition of 4-cylinder production becomes the only Toyota engine plant in the world to make 4-cylinder, 6-cylinder and 8-cylinder engines, Toyota said in a release Friday, Sept. 30.

The new Alabama-built 4-cylinder engines will be used in the North America-built Camry, Highlander, RAV4, Venza and Sienna. The expansion for 4-cylinder production gives the plant capacity for 216,000 units annually and brings total engine-production capacity to 506,000 units, Toyota said. The TMMAL plant began building V8s in 2003, V6s in 2005 and to date has produced nearly 1.8 million engines.
