BMW AG unveiled the X coupe on Monday, an indication of what a smaller version of the U.S.-built X5 sport wagon might look like.
BMW last year confirmed that it will develop an X family of all-wheel-drive vehicles off the X5 platform.
The X coupe provides a hint that the X3, the smaller version, comes first. That probably means that a bigger version, possibly called the X7, would come later. BMW is expanding capacity at its plant outside Spartanburg, S.C., to build a bigger range of vehicles.
Also at the Detroit show, BMW debuted the high-performance version of the X5, the 350-hp X5 4.6is. It goes on sale this fall.
BMW also unveiled the 333-hp M3 convertible, the latest body style for the present-generation 3 series.
