GM er Cars Engineered forquiet. And with asolid,comfortable feel. From the day the new Chevrolet Citation, Pontiac Phoenix, Oldsmobile Omega and Buick Skylark first started taking shape on the drawing board, a prime design objective has been to please the ear as much as the eye. Noise control through isolation. One of the ways we went about this was an all-out effort to iso late the passenger compartment from the engine, suspension and other chassis hardware. Body and engine mounts are specifically tuned to dampen or eliminate vibration frequencies that might prove annoying in side. There are vibration-absorbing couplings between mechanical components running from the engine compartment to the pas senger compartment-transmis sion linkage, acceleration pedal linkage, you name it. Even the MacPherson Strut front suspen sion and full-coil rear suspension have special cushioning devices that let you get a firm feel of the road without harshness of ride. Noise fighters. But isolation is just one form of controlling noise. To help cut down on wind-rush noise, these cars were extensively tested in the wind tunnel. All models feature Body by Fisher construction with fully framed doors and new door seals to help keep noise out. Hatchback models have auxilia ry seals in back. There are one piece, mass-backed carpets and foam-backed headliners. And special acoustical-insulation packages are available on certain models. If "quiet" engineering and a good ride are important in your selection of a car, we'd like to recommend that you test-drive these. You're in for a thoroughly de lightful experience.
