Yea we had a look at the ML with the 3.2. I decided to wait out for the MN as has a lot of improvements with safety and the drivers seat etc.
The 2.5 would eat the 3.2 over all with its 132kw and 400 mn of torque. Even with the 32" tyres on I stuck it on cruise in 5 the and it sat happily on 100 clicks at 2200rpm even in the hills. Has way less road noise than most cars. At 100 kmh feels like your doing 60 as so quiet.
There is a few 3.2 ML around here and most have been OK.
Hard to compare the two engines as the ECU has a big part in how they produce the power and torque.
The 2.5 has a soft flat torque curve and is no drag car off the line. Hard to explain but gradually builds up with more RPM to about 1700 then unleashes its full potential. Once in its sweet spot on the highway is amazing for a 2.5:)
We'll see how fuel usage is with the bigger tyres in time:eek:
Some have complained about the 2.5 being slow off the line compared to a 3.2. Had the ecu reflashed and fixed the problem.
Don't worry I was concerned about this little oiler my self;)
