The horsepower of the Porsche Macan 3.0 V6 340HP automatic 4x4 is 40 horsepowers grater than the Hummer H3 5.3 300HP. While the difference is small it should not affect the car performance considerably.
The width of the vehicle influences on passanger's inner room as well as stability of driving. The Porsche Macan is 2 % wider in comparison to the Hummer. It is clearly felt by those sitting in front, who have more room for their elbows.
The Porsche Macan 3.0 V6 340HP automatic 4x4 has 65 % longer wheelbase than the Hummer H3 5.3 300HP. The closer the axles are to one another, the less time exists for shock absorption by the separate suspension components. Therefore the Porsche Macan with a longer wheelbase will give the smoothest drive. Hovewer, the Hummer H3 with shorter distance between its axles have tighter turning angles and is able corner faster than equivalent cars having long wheelbases.
Model release date
Production of the older vehicle began 8 years prior to Hummer thus it is reasonable to suppose that this vehicle is equipped with significantly less modern solutions applied.
A stick shift that is placed in the Hummer is less complex built and is cheaper in usage but also it is less comfortable as it requires the driver to work with the clutch to change speeds and it can be lot of inconvenience in a jammed urban traffic where drivers have lots of frequent stop and go conditions. An automatic transmission in the Porsche Macan 3.0 V6 340HP automatic 4x4 with 7 – speeds transmission is in our opinion better one to have.
