ML 320 Bluetec
Hi everyone, new guy onboard. I have owned a few Mercedes and I am looking at a new vehicle. My lease is coming up and I am in line for a new ML. I am trying to choose between a slightly optioned ML 550 or a fully loaded ML 320 Bluetec. I am 95% of the way deciding on the Bluetec but there is a variable that is bugging me: Towing. The 2008 320 CDI can tow 7,200 lb but the 2009 has been de-rated to 5,000 lb. What gets me is that the GL 320 Bluetec is rated at 7,200 lb and the ML 550 is rated at 7,200 lb. How come in the ML 320 Bluetec application it is only rated at 5,000lb? MY suspicion is that it is an emission issue given the 50 state legal variant with the Urea injection. I have to tow a boat that is around +5,500 lb depending on the fuel and gear load and I don't want a vehicle that struggles.
Does anyone here have any insight on the issue? I am tempted to tow with the Bluetec and see how it goes. And I know that the 550 is kickass, but I already have a few gas guzzlers (plus boat). 25 mpg is looking good right now in an SUV.
