Tech in a Flash: General Motors’ Super Cruise System

Semi-autonomous driving systems are becoming increasingly common across the industry, but when it comes to citing reference technologies, two stand out: Tesla’s Autopilot and General Motors’ Super Cruise. But what is it exactly?

• Super Cruise launched with the Cadillac CT6 sedan

• It is now available on multiple models across the GM lineup

• GM is exploring new features to deliver greater autonomy

Assisted Driving

The Super Cruise system is a relatively advanced driver-assistance system. Launched at Cadillac and now available across General Motors’ other divisions, it enables hands-free driving on a growing number of roads and highways throughout Canada and the United States. At its launch seven to eight years ago, GM talked about the potential to drive hands-free on approximately 640,000 km of official roads eventually.

By the end of 2025, the company’s projections are now approximately 1.2 million kilometres of roads, still throughout Canada and the United States. Initially, this was only possible on highways, but today, the system recognizes many rural roads and urban boulevards.

And the distinction is important here. Some semi-autonomous driving systems use radars to detect lane markings and help keep the vehicle in its lane. Super Cruise uses high-precision LiDAR road maps (a 3D laser-mapping technology) and knows the curves and geometry of the road several kilometres ahead of you. In other words, the system knows better than we do what lies ahead.

Hands-Free

Super Cruise allows drivers to remove their hands from the steering wheel. It’s important to note that the driver must always remain attentive to the road. The system continuously monitors the driver’s head and eyes to ensure their gaze remains forward. If they look elsewhere, they will be alerted. If inattention persists or recurs, the system deactivates until you bring the vehicle to a complete stop.

Semi-Autonomous

Using the term semi-autonomous is essential. Super Cruise is not an autonomous system. In fact, according to automotive industry standards (the Society of Automotive Engineers (SAE) classification), Super Cruise is at level 2 (out of 5) in terms of automated driving. It means the system can control steering, acceleration, and braking simultaneously, but the driver must remain engaged and ready to take back control at any time. Note, however, that GM is exploring future technologies that could allow for greater driver autonomy, such as the ability to take one’s eyes off the road. Nothing confirmed so far.

Impressive Features

Initially, Super Cruise kept the vehicle in its lane and at a respectful distance from the car ahead. The system is now capable of performing automatic lane changes with a simple turn signal activation, or even autonomously if it encounters a slower vehicle on the highway. It can even position us in the correct lane for an exit, based on the GPS route entered in the system.

With certain vehicles, Super Cruise also works while trailering (without the lane-change function for now).

Super Cruise has proven highly reliable so far, with millions of kilometres logged by users and no significant incidents reported. It allows one to relax behind the wheel, especially on long trips.

Super Cruise is available on more and more models across the GM family line-up. The system offers a trial period. A subscription is subsequently required.

In every respect, an impressive system.
