New details have surfaced about BMW's X4 crossover.

According to Auto Express, the X6's sibling will be based on the 2011 X3 and feature coupe-like styling. The model is also poised to receive the innovative twin-hatch system (from the 5-Series Gran Turismo) and individual seating for four.

Under the hood, engine options will carryover from the X3. This means we can expect a turbocharged 2.0-liter four-cylinder diesel with 181 hp (135 kW / 184 PS) and a turbocharged 3.0-liter straight-six petrol with 300 hp (225 kW / 306 PS).

An X4 concept will likely debut next year and, if public reception is good, BMW could put the model into production as early as 2012.  If approved, the X4 would compete with the Land Rover Evoque and Mercedes GLC.
