1978-79: Dodge D and W100, D and W200 Pickups

Diesel World - - Vintage Smoke -

Dodge also jumped on the full-size diesel truck band­wagon in 1978. Their D and W150 (half-ton) and D and W200 (three-quar­ter ton) mod­els of that year fea­tured a six­cylin­der diesel op­tion, namely a su­perb 3.98L Mit­subishi in­line six (6DR5). Avail­able only in ’78 and ’79, it shared gen­eral de­sign ar­chi­tec­ture with the 2.6L diesel four that would come later to the Ram 50 im­ports. This was an ex­tremely good en­gine, but be­ing nat­u­rally as­pi­rated with only 100 hp on tap it was out­classed in light trucks with up to an 8,400-pound GVW. With the op­tional au­to­matic per­for­mance was even less in­spi­ra­tional. Yeah, it was an­other diesel vic­tim of bean count­ing that failed to in­spire the truck-buy­ing pub­lic to go diesel. Had Dodge opted for the tur­bocharged 6DS5 vari­ant, at about 130 hp and over 200 lb-ft, the diesel en­gine could have at least matched six-gasser per­for­mance.
