As Buick continues to introduce new products to the market, its QuietTuning™ system becomes more of a hallmark for the up-scale nameplate. The latest to include the system is the Buick Lucerne, the vehicle set to replace both the LeSabre and the Park Avenue.

The Lucerne was introduced Wednesday at the Chicago Auto Show. As part of the QuietTuning system, the Lucerne will feature laminated glass side windows in all four doors as standard when it goes on sale later this year. The windows will contain Solutia Automotive's Saflex(R) polyvinyl butyral (PVB) automotive glass interlayer.

The Cadillac DTS, also unveiled Wednesday at the Chicago Auto Show, will offer laminated glass side windows in all four doors as a standard feature when it goes on sale later this year.

Cadillac included laminated side glass as an enhanced security feature for the top-of- line luxury vehicle, according to a spokesman for Solutia, whose interlayer is used in the units.
