Cadillac will add 70,000 more miles of Super Cruise-capable highways in the United States and Canada by the fourth quarter of 2019, and the expansion will bring the total distance of the supported roads to over 200,000 miles. The Super Cruise system will prompt drivers to take control on portions of the new routes when driving through railroad crossings, crosswalks, traffic lights, and stop signs. The image below reveals what's new.

Cadillac Super Cruise Update

There are actually two parts to this improvement: updated software and the expanded maps.  Owners of the 2018 and 2019 Cadillac CT6 will be able to get the improved software from Cadillac dealers. The tweaks also allow the newly supported roads to come via over-the-air updates this summer and fall.

The software update includes "performance enhancements for when a driver is traveling with Super Cruise in traffic situations and around tighter curves," according to Cadillac spokesperson Katylnn Downey. "We made slight refinements to the driver attention system to even more accurately detect driver attention and improvements to overall general availability detection." 

Super Cruise is currently exclusive to the CT6, but Cadillac finally expands the tech's availability by offering it on the new CT5 sedan. The company also intends to make the system an option on the XT4 eventually.

In June 2018, Cadillac announced that Super Cruise would eventually be available on its entire lineup, with the expansion starting in 2020. In the future, the system will also be available in other General Motors' vehicles. The company won't yet say which models will get the tech first, though.

Super Cruise uses a mix of Lidar, GPS, cameras, and radar to allow for hands-off driving on certain roads. Sensors on the inside of the vehicle monitor the driver and make sure the person is actually watching the road.

The company's next goal is to implement V2X communication where vehicles are able to share data with other cars and the infrastructure. These networks would then let a system like Super Cruise what's happening ahead before a person could ever see it.

Cadillac to Increase Super Cruise Compatible Highway Network  
70,000 additional miles to be available for hands-free driving by Q4 2019

Cadillac is expanding the availability of Super Cruise™  to an additional 70,000 miles of compatible, divided highways in the United States and Canada. This expansion will make the industry’s first true hands-free driver assistance feature available on more than 200,000 total miles of compatible highways by the fourth quarter of 2019.

To date, Super Cruise has been available on more than 130,000 miles of limited-access freeways. The expansion builds on Super Cruise’s unique combination of precision LiDAR map data, high-precision GPS, a state-of-the-art Driver Attention System and a network of camera and radar sensors. Some of the divided highways added will include limited intersections and traffic control devices. In the cases of railroad crossings, pedestrian crossings, stoplights or stop signs, Super Cruise will alert drivers to take back control of the vehicle.  As always, it remains important for drivers to stay engaged and vigilant at all times while Super Cruise is engaged.

To enable the expanded functionality, an enhancement to the Super Cruise system will be available to 2018 and 2019 model year Cadillac CT6 owners through their Cadillac dealer. Following the completion of the system enhancement, the new, additional map miles will be sent to customer vehicles over the air throughout the summer and fall. 

In addition to the mileage expansion, the software update will also include performance improvements, enhancements to increase Super Cruise availability and enhancements to the Driver Attention System.

“We are constantly working to make Super Cruise the most beneficial system for our customers,” said Mario Maiorana, Super Cruise chief engineer. “Expanding our offering of compatible highways will allow people the ease and convenience of traveling hands-free more often.” 

Last year, Cadillac made updates to its Super Cruise driver assistance feature based on customer feedback, including making Super Cruise activation easier for the driver and adding dynamic lane offset so that a CT6 with Super Cruise activated can adjust slightly over in its lane for driver comfort when passing large vehicles. Gauge cluster messages were also added, to inform drivers why Super Cruise may be not be available in certain instances.  

Customers have traveled 2.5 million miles using Super Cruise since its launch. Super Cruise is currently available on the 2018 and 2019 model year Cadillac CT6 and will be available on the 2020 model year CT6 later this year. Super Cruise will be available on Cadillac’s all-new CT5 sedan next year.
