The 2018 Cadillac XTS represents the pinnacle of American luxury sedans, receiving significant updates that elevate its design, technology, and driving dynamics. As Cadillac's flagship front-wheel-drive model, the XTS bridges the gap between premium accessibility and full-size luxury, offering a compelling alternative to both European rivals and its larger CT6 stablemate.

Exterior Redesign: A More Cohesive Cadillac Look

Cadillac's design team delivered thoughtful updates to the XTS's exterior that align it with the brand's evolving design language:

  • New front fascia featuring a more pronounced grille and redesigned fenders
  • Full LED lighting front and rear for improved visibility and modern aesthetics
  • Revised bumper designs that enhance the car's road presence
  • New wheel designs ranging from 19 to 20 inches, with Platinum models receiving exclusive 20-inch alloys

These changes create visual continuity with newer Cadillac models like the CT6 while maintaining the XTS's distinctive character. The LED lighting package not only modernizes the appearance but also provides superior nighttime illumination compared to previous halogen setups.

Interior Upgrades: The CUE Revolution

Cadillac XTS review

The 2018 XTS addresses one of Cadillac's most criticized areas with a comprehensive upgrade to its Cadillac User Experience (CUE) infotainment system. The new generation system represents a significant leap forward in:

Performance Improvements

Processor upgrades deliver near-instant response to touch inputs, eliminating the lag that plagued earlier versions. Menu transitions are now fluid and intuitive.

User Experience Enhancements

Redesigned interface with more logical menu structures and customizable home screens. The 8-inch capacitive touchscreen now rivals class leaders in responsiveness.

Connectivity Features

Includes 12-month trials for both the cloud-connected navigation system and OnStar services, with 4G LTE Wi-Fi hotspot capability.

These improvements helped Cadillac address the satisfaction gap identified in consumer surveys, where previous CUE systems trailed competitors like FCA's Uconnect and GM's own MyLink/IntelliLink systems. The ability to create personalized driver profiles adds another layer of convenience for multi-driver households.

Powertrain and Performance

The 2018 XTS continues with two proven engine options, both mated to six-speed automatic transmissions:

Standard 3.6L V6

  • 304 horsepower and 264 lb-ft of torque
  • Direct injection and variable valve timing
  • EPA-estimated 18 mpg city / 28 mpg highway (FWD models)

V-Sport Twin-Turbo 3.6L V6

  • 410 horsepower and 369 lb-ft of torque
  • Twin-scroll turbochargers for immediate response
  • Performance-tuned suspension and brakes

Available all-wheel drive with electronic limited-slip differential enhances traction in adverse conditions, while the optional adaptive suspension automatically adjusts damping rates for optimal ride comfort or handling response.

  • Revised suspension tuning for better ride isolation
  • Enhanced noise insulation materials throughout the cabin
  • Improved steering calibration for more natural feedback
  • New wheel designs optimized for both aesthetics and ride quality

These changes maintain the XTS's reputation as one of the most comfortable cruisers in its class while adding a degree of handling precision that appeals to driving enthusiasts.

The refreshed XTS occupies a unique space in the luxury sedan market:

Against European Rivals

Offers more standard features and interior space than comparably priced BMW 5 Series or Mercedes E-Class models, with a distinctly American design aesthetic.

Within the Cadillac Lineup

Sits between the midsize CTS and full-size CT6, providing front-wheel-drive convenience with nearly CT6-level interior dimensions.

Value Proposition

Delivers luxury amenities at a price point typically $5,000-$10,000 below German competitors with similar equipment levels.
