Answer 1

Binary variable signaling the engine cylinder configuration as either:

V-shape (vs=0) or Straight Line (vs=1)

Configuration offers trade offs in power/torque, design usage in terms of space/size of engine and performance or center of gravity of vehicle. The geometry and placement of the engine, as influenced by its cylinder head, can have numerous knock-on influences on the vehicle beyond the technical engineering considerations of the cyliner angle.
