This platform was shared with the Pontiac Grand Prix, Chevrolet Malibu, Olds Cutlass Supreme, etc. It was a few hundred pounds lighter than the old B-body platform Station wagon and sedan were the two body styles. Two engines were carried over from the old B-body version. These were the 231 V6 and 350 Diesel. Two others were added, which were a 252 CID 2bbl Buick V6 making 125hp, and a 262 CID Diesel Oldsmobile V6 making 85hp.
