WOW....please just read the 3 stickied posts at the top of the 2nd Gen Forums...they will explain it better than anything

One of the diff is that the s4 engine has a mechanical; oil pump and the s5 is an electrical one olso the exterior of a s4 has some diff one is the tail lights and side molds.
I think also the s5 angine came with more power then the s4. just check the FAQ
