Cadillac recently announced that it is expanding the amount of roads compatible with its Super Cruise advanced hands-free driver assistant, which will soon cover over 400,000 miles of North American roads. While the Cadillac Escalade will receive the full scope of the massive update, the Cadillac CT6 will only receive a fraction of it.
As part of Cadillac parent company’s, General Motors, plans to increase the amount of roads compatible with Super Cruise, the Cadillac CT6 will receive an upgrade that will only add 20,000 miles of eligible highways. That’s because the luxury sedan does not have the software necessary to accept the full upgrade, as it wasn’t built on the Global B electrical vehicle architecture, and its current platform is unable to support the full, 400,000 mile Super Cruise expansion. The Cadillac XT6 is also faced with a similar issue, as it will also receive a much smaller Super Cruise expansion due to its outdated electrical architecture.
As a reminder, Super Cruise (production code UKL) allows drivers of an equipped vehicle to take their hands off the steering wheel and feet off the pedals on compatible roads.
The 2020 model year was the last for the Cadillac CT6 sedan in North America before it was discontinued. For its final model year, the CT6 was available with one of two engines. The first was the naturally aspirated 3.6L V6 engine (production code LGX), rated at 335 horsepower and 284 pound-feet of torque. The second was twin-turbocharged 4.2L V8 engine (production code LTA) gasoline engine. Otherwise 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 made 500 horsepower and 574 pound-feet of torque.
Under the skin, the Cadillac CT6 rode on the Omega platform. Production for the North American markets took place at the GM Detroit-Hamtramck plant, now known as GM Factory Zero.
