The 'Ecotec' V6 uses direct injection, but not piezo injectors like BMW, they use a solenoid injector. The Ford drivetrain engineer/PR flak I talked to this year said they didn't see a significant increase in performance/mileage to warrant using the more complex DI that BMW employs.
So rather than have an injector above the combustion chamber, they spray on the side and use a 'lip' (seawall?) on the piston to 'bounce' fuel off of. A pic is attached:
