Im using 2015 ML350, the previous model of ML400 and GLE series. Basically they are all same, the newer version accelerate a bit faster but performance are just not changed much, I tried it all including the new GLS400 which giving same driving impression like an ML/GLE. Have owned BMW X5 before, it was a very performance car with sport package, wide tires, the new X5 inherited it all, including its heavy steering, rather hard for you when driving slow in street. Also tried Cayenne 2016 base V6 and Range Rover Sport HSE 2015 recently, both give good impression on driving but not much diffrent to my current ML350, just not worth the big gap of price and heavy maintenance cost. Cayenne is rather too narrow inside and cargo compartment compared to ML, while Range Rover Sport having reliabilty issues with its electronic and air shocks. How a ML can be comparable to cayenne/range rover in term of driving impression ?
Benz ML350/ML400/GLE with OEM shocks and springs give you very soft ride like a sedan but do not have the stability, sporty driving feeling that I can find in X5 and Cayenne, you are like on a boat on unflat road. After researching, I decided to change the stock 19" wheel to AMG 20" with 265/45R20 tire, have the B12 Bilstein/Eiback sport combo set of shock/sping in to lower the car about 3cm and give harder shock absorbtion. The result is really fantastic, my car now having both soft/smooth/comfort of Benz/Range Rover on flat road and sport feel/car stability/response to the driving wheel of an X5/Cayenne on uneven road. I guess a set of rear tire 295/40R20 will even give better stability. Acceleration of ML350 is better than a base V6 Cayenne and Range Rover Sport 2015 (engine noise is too much). Driving ML is just much more relaxing and easy on crowded street and normal country side road, thought not very exiciting on highway unless you order an SUV with sport mode. For less money, same option, Benz ML is a much smarter choice to cayenne/rover sport which are usd50k more expensive in my country. Audi to me is not reliable engine bcs they are of VW group. The outlook may make decision but its up to uyour taste. Im not very engaged with ML but the new GLE look more sporty. I was wondering Cayenne/range rover sport/X5 against ML but now I know I made good choice.
