4G LTE is the most current and fastest mobile data network – 10 times faster than
3G and 100 times faster than the previous generation of OnStar hardware. And
with OnStar, it also offers stronger, broader coverage than smartphones on the
same network and it’s easy to use: If the vehicle is on, the connection is on.
At the time of purchase, one year of OnStar Directions and Connections includes all
of OnStar’s advisor-based safety and security features, including Automatic Crash
Response and Stolen Vehicle Assistance, as well as Turn-by-Turn navigation.
Five years of OnStar Basic Plan includes RemoteLink Key Fob Services, allowing
owners to remotely start and lock/unlock a car (if properly equipped), and activate
the horn and lights from anywhere with a data connection. It also includes OnStar
Vehicle Diagnostics, which runs monthly checks of a vehicle’s engine, transmission,
anti-lock brakes and more, and Dealer Maintenance Notification, which sends a
diagnostic report directly to a preferred dealer, simplifying service scheduling.
XTS powertrains
The Cadillac Twin-Turbo 3.6L V-6 headlines the XTS’s powertrain lineup and is
standard on Vsport models, delivering SAE-certified 410 horsepower (306 kW) and
369 lb-ft of torque (500 Nm) – making it one of the most power-dense six-cylinder
engines in the segment. A pair of smaller turbochargers and an efficient charge air
cooler help provide more immediate power delivery, while peak torque is sustained
over a broad range – 1,900 to 5,600 rpm – for a confident feeling of power when
accelerating or overtaking traffic on the highway.
The twin-turbo engine is a comprehensive upgrade on the 60-degree, 3.6L DOHC V-
6 that is offered as the standard engine in the XTS. However, almost every
component is unique:
All-new cylinder block casting
Strengthened connecting rods
Machined, domed aluminum pistons with top steel ring carrier for greater
strength
10.2:1 compression ratio
Patented, integrated charge air cooler system with low-volume air ducts
Two turbochargers produce more than 12 pounds of boost (80 kPa)
Vacuum-actuated wastegates with electronic control valves
All-new direct injection fuel system
Tuned air inlet and outlet resonators, aluminum cam covers and other
features that contribute to exceptional quietness and smoothness.
The cylinder heads are also unique to the Cadillac Twin-Turbo. They feature a high-
tumble intake port design that enhances the motion of the air charge for a more-
efficient burn when it is mixed with the direct-injected fuel and ignited in the
combustion chamber.
