The engine, now on its way to the Regensburg vehicle plant in Germany, was built to order and ultimately destined for a British customer purchasing a 318i Saloon - the UK's best selling BMW model.
Coinciding with the celebration of this key milestone was a visit from Harald Krüger, member of the board of management of BMW AG for Human Resources and Industrial Relations, and the former plant director of the Hams Hall production facility.
"To reach two million engines is a fantastic achievement," said Krüger. "The Hams Hall plant is our centre of competence for the production of fourcylinder petrol engines within the BMW Group and is a credit to the skill, flexibility, commitment and motivation of the Hams Hall workforce."
"There is a strong team culture at the plant and we have a highly skilled and committed workforce with a wealth of experience," said plant director, Mathias Hofmann.
"Our engines are built to the highest standards of quality and delivered to the vehicle production plants in the exact sequence they are required. Everybody at the plant is proud of reaching this major milestone and to be building engines that power both BMW and MINI vehicles sold across the world."
