[x-darekk-x]

dzisiaj w anaheim rynkowa premiera hummera h3. wyglada niemal identycznie jak
h2, tyle ze w skali 4:5. a pod maska? 5-cylindrow. :(

[greenblack]

Skąd oni wytrzasnęli tego pięcocylindrowca? GM w ogóle robi takie silniki?

jak widzisz - ten sam silnik z dolozonym 1 lub 2 cylindrami. te same srednice i
skoki tloka. ta sama konstrukcja bloku.

A wiecie, ze to jest Isuzu?

[cracovian]

A dokladnie Isuzu D-Max? Colorado jest wlasnie budowany na tej popularnej w
Azji platformie, nawet kierwonicy GM nie zmienili. H3 to Colorado z
przybudowka. Tylko ten nieszczesny silnik...

Przy strasznie zawyzonych cenach Colorado mysle, ze bedzie kiepsko ze sprzedaza
duzo drozszego Hummera H3 podczas gdy H2 ma tak wysokie teraz rabaty.
