With BMW introducing the 2013 6 Series Gran Coupe this week to the press, the automaker let a little more information slip about the future of its entire lineup regarding engine options.
The 2013 BMW Gran Coupe is slated to have two engine options available in the U.S.—a 315-horsepower, turbocharged 3.0-liter inline-6 and a 445-horsepower twin-turbocharged V-8. And up until now those engines with those power outputs have remained exclusive to the Gran Coupe, with all other inline-6 engines receiving 300 horsepower and V-8s rated at 400 horsepower in its North American-bound cars. The only exceptions have been the special-edition 2012 BMW 1 Series M, 335is, and the upcoming 2013 BMW 135is sports coupe.
But while discussing the 640i Gran Coupe this week, BMW said during its presentation that those upgraded engines will be supplanting the old six- and eight-cylinders throughout its car lineup. Representatives on-hand said horsepower output would not be affected in four-cylinder cars—rated at 240 horsepower in the 2012 BMW 328i, X3 crossover, and upcoming 2013 BMW X1—or SUV models. That means the X1, X3, X5, and X6 will likely be carrying over with very few differences under their hoods when the 2013 versions of each of them go on sale later this year.
