The Cadillac XTS full-size luxury sedan will receive several enhancements for 2018, including Cadillac's next-generation connectivity platform, an improved chassis for greater ride comfort and a refreshed appearance, General Motors has announced.

The 2018 XTS will feature the Cadillac user experience, a cloud-based connected-vehicle system that provides navigation and proprietary applications that allow users to connect smartphones to control climate, audio, phone, and navigation.

The updated chassis includes new tires for 19- and 20-inch wheels, changes to seat geometry, and additional sound insulation.

The front-wheel XTS is built on the Epsilon II platform that it shares with the Chevrolet Impala and Buick LaCrosse.

General Motors is offering a $3,600 fleet incentive for the XTS (excluding W30) for the 2018 model year.
