Re: Multidisplacement engine
LOL If the salesmen get their info from the car literature why does he tell me its gets 20% better mpg when the literature clearly says 15% better? (besides 15% better would only be true if you are running the motor on a stand, not in an actual vehicle..in a totally controlled environment. actually I dont think it gets even 1mpg better, it really seems to get about the same mpg as any other V-8) In an actual vehicle, under real driving environments, MDE doesnt make a bit of difference.
The literature does specify that multidisplacement takes place between 40-60 mph...my salesman tells me that only 4 cylinders are working (getting fuel) at any speed as long as the throttle is steady, or just cruising along down the highway.....he said it only kicks to 8 cylinders when you accelerate...HMMMMM?
SO...if multidisplacement function only works from 40-60 mph..that means that the engine is not running on 4 cylinders very often...who drives down the hwy at 60mph?
And when youre drivig in the city, I guess you are within that speed range alot but you also have to accelerate alot...so its no wonder that the Hemi with the MDE feature averages 13mpg in town. I REALLY like the Commander but I'm not sold one bit on the Multidisplacement feature as being a viable and usefull fuel saving advantage. I think its a gimmick personally...made to help sell this SUV. Its the only feature on this vehicle I find suspect.
