Sprinter four-bangers now standard with RTs?
I checked with the RT folks... I know the SS Agile gets the four banger, and I'm pretty sure the other models do as well.
Why the wholesale abandoning of the V6? It may have less MPG, but it definitely gives a smoother and more powerful ride, especially in hilly areas, and if towing something. Plus, the V6 has had most of its issues thrashed out, so it is fairly reliable.
