FRANKFURT - German carmaker BMW AG said Thursday that it will add two new models to its line of Mini cars.

One of the models will be a coupe, while the second model will be unveiled at the Frankfurt Auto Show Sept. 15, Munich-based BMW said in a statement.

The coupe will be a two-seater and likely feature a 1.6-liter turbocharged Mini John Cooper Works engine. Details of the second new model were not announced — and neither were dates for the start of production for either car.

BMW said both models would be produced at the Mini plant in Oxford, England.

The two new cars join Mini Hatch, Clubman and convertible models already produced there.

"The production of the two new Mini models is very good news for Oxford, and for the U.K. car industry," British Business Secretary Lord Peter Mandelson said, welcoming it as "a demonstration of BMW's long-term commitment to the U.K."

BMW shares closed down about 1.3 percent at €30.10 ($43.04).
