When the service expires for owners of the 2018 model year CT6, US customers will be able to purchase a standalone Super Cruise plan for $25 a month, which adds up to $300 a year. If you’re already subscribed to other select OnStar and GM Connected Services bundles, Super Cruise can be added for an extra $15 a month.
Owners that don’t subscribe to Super Cruise will still be able to use the car’s lane-keep assist, and adaptive cruise control, but Super Cruise functions will no longer work meaning you’ll no longer be able to enjoy hands-free driving on over 200,000 miles of US highways.
