Right now, the flagship Cadillac CT6 is the only model that comes with the automaker's superb Super Cruise autonomous driving system. This is about to change, however. We've known for a while now that Cadillac is planning to add Super Cruise to every model in 2020 after the CT6 is discontinued. Now, the automaker has confirmed that Super Cruise will be added to the 2021 Cadillac CT5 and CT4, followed by the all-new 2021 Cadillac Escalade, which debuts on February 4. Best of all, Cadillac's new version of Super Cruise has been updated with new enhanced features.

Among the enhancements will be a new automated lane change system that allows the hands-free driver-assist to change lanes on certain highways when requested by the driver and certain conditions are met.

"This is our most extensive update we've made to Super Cruise since its debut," said Mario Maiorana, Super Cruise chief engineer. "We have made a number of improvements to make Super Cruise more intuitive, better performing and more accessible for our customers. In addition to the automated lane change functionality, we've made improvements to the user interface and hands-free driving dynamics."

Activating this system simply requires the driver to tap or fully latch the turn signal to indicate that they want to change lanes. The system will then check to see if the indicated lane is open using an array of camera and radar sensors, while also letting other cars know that a lane change is imminent. If the system detects the conditions are safe, the car will merge into the desired lane. However, the driver attention system will still require the driver to focus on the surroundings during the lane change.

The gauge cluster will also display messages such as "looking for an opening" or "changing lanes" to inform the driver when the automated lane change has begun or if a lane change is unavailable.

Other enhancements will include more improved map information to enable automated lane change and improved functionality through turns and highway interchanges, improved software for better steering and speed control, and enhancements that "make it easier and more intuitive for drivers to engage the system."

Cadillac's Enhanced Super Cruise with automated lane change will be available as an option on the 2021 CT4 and CT5 sedans and the 2021 Escalade in the second half of 2020.
