The horsepower of the Mercedes GL-Class X164 Off-roader 450 4MATIC 340HP automatic 4x4 is by 40 horsepowers grater in comparison to the Hummer H3 5.3 300HP. Because the difference is not big this should not affect the vehicles performance in a noticeable way.
The width of the vehicle influences on passanger's inner room as well as stability of driving. The Mercedes is 27 mm wider in relation to the Hummer H3 5.3 300HP. It is often clearly felt by driver and passenger in front, who have more room for their elbows.
Mercedes has 9 percent longer wheelbase in relation to the Hummer H3. A longer wheelbase gives more stable and comfortable ride, especially at higher speeds. It also provides more storage space. But, cars having a longer wheelbase are not as maneuverable as those with a shorter wheelbase.
The Mercedes GL-Class X164 is 8 percent longer in comparison to the Hummer. The length of the car is significant in respect of driving comfort and space in the boot. The Mercedes GL-Class X164 probably will be offering to it's passangers more room for legs. At the same time the Mercedes GL-Class X164 will be better driven but the Hummer H3 will be a slightly easier to park due to shorter length .
Model release date
The difference in date of commencement of production between presented cars is only 1 year, however, new technologies for vehicles are appearing at a staggering pace and for that reason the Mercedes GL-Class X164 Off-roader 450 4MATIC 340HP automatic 4x4 may feature more modern technologies.
A stick shift that is placed in the Hummer H3 is less complex built and is cheaper in usage but it is less comfortable as there is no need to work with the clutch to shift gears very often, especialy in a bussy city traffic where we have lots of stop and go situations. An automatic transmission which is in the Mercedes GL-Class X164 with gears in the amount of 7 – speeds gearbox is in our opinion better to use.
