I wonder what it would be like to knock 2 cylinders off the 3.7 V6 and make a 2.5 V4. I bet it would sound fantastic.
it might sound rougher than you think. Ford 3.7 has a 60 degree bank angle, whereas to balance the primary forces in a V4 would need a 90 degree angle (or the addition of balancer shafts to overcome the mismatch of firing forces - usually an engineering bodge)
