Which in turn has downsides of it's own, it turns out there are limits on how much armor you can put on engine area, thus limiting your frontal arc protection. Front mounted engine was a good idea when Mk. I was being designed, but since then advances in armor technology surpassed it.
APCs and IFVs on the other hand have smaller engines and don't mount that much protection, not to mention that rear exit for dismounts is a must, as amply demonstrated by BTR-60/70/80.
