2015 Ford Mustang GT: Coyote Voodoo Cross-Plane Flat-Plane (Ridiculous name) -Super Duper Fantastic
Cause it's not the engine's name. An engine crankshaft is either cross plane
or flat plane, not both.
For the record, it's the 5.0L Voodoo which has the flat plane crank. The 5.0L Coyote is the cross plane.
