GM has recently announced the coverage expansion of its Super Cruise hands-free driving system, and the automakers’ full-size SUVs are now being built with the updated software allowing owners to use Super Cruise on more than 400,000 miles of roads in the United States and Canada. However, the Cadillac CT6 will receive a much smaller coverage expansion.
As part of GM’s commitment to improve its advanced driver assistance systems (ADAS), Super Cruise (RPO code UKL) accessibility for the Cadillac CT6 has been increased to include an extra 20,000 miles of compatible roads.
For those wondering why the Cadillac CT6 won’t be getting the full expansion, the explanation is simple. The CT6 wasn’t designed using GM’s Global B software architecture – aka Vehicle Intelligence Platform. This means that the Caddy is unable to exploit the full capabilities of Super Cruise.
There are three vehicles that will be getting the 20,000-mile update, including:
These vehicles are now being built with the full 400,000-mile expansion:
- 2023 Chevy Tahoe
- 2023 Chevy Suburban
- 2023 Cadillac Escalade and Escalade-V
- 2023 Cadillac Escalade ESV and Escalade-V ESV
- 2023 GMC Yukon
All other GM vehicles equipped with Super Cruise from prior model years will receive the Super Cruise update via an over-the-air update.
The road coverage expansion follows GM’s plan to offer Super Cruise in 22 models by the end of the 2023 calendar year. On top of that, Ultra Cruise will also be introduced in the near future, and one of the first models to receive it will be the Cadillac Celestiq.
As a reminder, the 2020 model-year Cadillac CT6 was the last for the full-size sedan in North America, and was available with one of two powerplants. These include the naturally aspirated 3.6L V6 LGX gasoline engine, rated at 335 horsepower and 284 pound-feet of torque, and, for the performance-oriented Cadillac CT6-V, the twin-turbocharged 4.2L V8 LTA gasoline engine. Also known as the Blackwing engine, the LTA produced 550 horsepower and 640 pound-feet of torque, while a detuned version of the LTA offered in the CT6 Platinum developed 500 horsepower and 574 pound-feet of torque.
