Last year, Oldsmobile dumped the stodgy Cutlass Supreme for the Intrigue; a suave, sophisticated sporty sedan designed to take on the best of the imports. For '99 Olds is dumping the 3800 Series II V6 that powers the Intrigue for an all-new, 24-valve 3.5-liter twin-cam V6. Until production of the 3.5-liter (a design based on the Aurora V8) can be ramped up to meet the Intrigue build schedule, the new 215-horsepower engine will come standard only in the new top-line GLS model, and optional in the base GX and mid-line GL series. Full function traction control is now available in models equipped with the new power plant. Minor feature revisions, one new color and new badging rounds out the changes this year.
