ATS
The ATS Sedan is discontinued; and yes, this includes the raucous twin turbocharged ATS-V. Cadillac is not giving up on fighting the BMW 3 Series, which the ATS Sedan did admirably, but a new, even better compact Cadillac Sedan is coming, the CT4.
The ATS Coupe continues for the time being, including the 464-horsepower ATS-V Coupe. However, the 2.0 Turbo ATS Coupe no longer offers the manual transmission. Only the ATS-V still comes with a clutch. #SavetheManuals.
CT6
The CT6 gets a redesign for 2019, ironically since this may be its last. The redesign incorporates a new mesh grille new headlight shapes and a new lower fascia.
A new CT6-V (previously announced as V-Sport) variant gets a powerful 4.2 double-overhead cam 550-horsepower twin turbocharged V8.
Active Noise Cancellation is now standard.
The CUE infotainment system is improved.
The standard backup camera is now in high-definition; the Surround Vision option now includes a recorder.

Escalade
A new sport appearance package features Black Ice Chrome grille, lower fascia trim, bodyside moldings and rear appliqué and black gloss window trim. It comes with unique 22-inch wheels in one of two finishes. Next year a fully redesigned model is coming.
XT4
Cadillac's new compact sport utility competes with the BMW X1, X3, Audi Q3, Lincoln MKC, Infiniti QX30, Jaguar E-Pace, Mercedes GLA, Volvo XC40 and others.
The XT4 is not a Buick Encore twin; the XT4 has a longer wheelbase and more cargo and passenger space.
A powerful 2.0-liter turbocharged 4-cylinder provides 237 horsepower and 258 pound-feet of torque through a 9-speed automatic transmission to the front or all four wheels. 18 or 20-inch wheels are offered, the latter with 245/45R20 all-season tires.
Cadillac is not making the leading-edge safety technology standard on the XT4, collision warning, autonomous braking, blind spot warning, rear cross-traffic warning, reverse automatic braking and lane departure warning are all offered, but not on base models. A full complement of airbags, eight, are standard, including knee airbags for the driver and front passenger.
Luxury features are amply available: heated front and rear seats, ventilated and massaging front seats, adaptive cruise control, power hands-free liftgate, memory for seats, mirrors and power tilt and telescoping steering wheel are all offered.
XT5
Driver Assistance Package is now standard on XT5 Platinum. It includes adaptive cruise control, automatic seatbelt tightening, automatic park assist (parks for you, with the driver controlling the brake), forward and rear automatic braking.
Ventilated front seats are no longer offered except as standard on Premium and Platinum.
