like many said... many "common" items are developed with or obtained from others... volvo used to use garret industries turbochargers (just about on all the rwd models)...they switched to mitsubishi for the 850 (and subsequent cars developed after).... now they have also used kkk (german) turbocharger on the new s60r/v70r. bosche motronic 4.3/4.4 engine managements were used...now it's bosche's me7+.... think the wiper blades are bosche too? shocks/struts are boge.. there is nothing really to worry about...since volvo was really more of an independent company .. and i'm guessing the mistubishi misconception is more the fact that mitsubishi is a gigantic company, they have all kinds of divisions.. from consumer electronics, to airconditions, to trucks, to cars, to turbochargers... and lets not forget the mitsubishi zero fighter plane from ww2... the mitsubishi collaboration on the 850 is simply with the mitsubishi heavy industries (i think that's what the turbocharger division is called...forgot)...not mistubishi cars...

even the inline-5 engine, altho still built by volvo, had input from audi/porsche for technical advice during development. specifically, volvo wanted a modular engine unit... e.g. one that could function as a i4 or i5 or i6, by simple addition of extra cylinder...

but the chassis, design, shape is all volvo... ford's major input did not start, has not start yet... the upcoming s40/v50 is based on the next-gen ford focus.. which is among the best fwd chassis in the world for the class... a ton better than the out-going charisma based s/v40... i still think ford's acquisition of volvo sits better in my stomach than renault's bid which fell thru...
