Not a bad looking SUV with a diesel to boot. Estimated 28 hwy mpg. Probably a great SUV for someone who drives a lot of hwy miles and tows. Link

It is an interesting engine. Seems like more electronic actuators than any other engine that comes to mind. A neighbor has Silverado with it and he tows a pontoon boat or TT with it never had a conversation about though. The EGR tap behind the DPF is clever be interesting to what the insides look like at 100k in terms of soot. Is it a Denso or Bosch fuel sys?
It has a Denso fuel injection system and yes I agree using post DPF exhaust for the EGR system was brilliant. The only thing with this is they are now routing extremely hot exhaust during the regen process into the EGR system, but I think it was a good choice to prevent the EGR valve and cooler from getting plugged with soot.
IMO I still have my concerns for these diesels that are running around town and never run long enough to get hot so a complete regen can occur.
