Yeah, the gen4 is now a 4 cylinder turbo or a turbo hybrid making more hp and torque. Along with that, likely more maintenance to worry about, especially when you get in that upper mileage range. At any rate learned my lesson when it comes to these 1st year models, I now let someone else be the R&D guy.Sounds good! I read on the internet that the gen 4 doesn't have a V6, which really sucks!
