Super Cruise’s failsafes

Even though Super Cruise is not a fully autonomous system, it incorporates redundancies like those used in aircraft to ensure failsafe operation. Before taking off on a 700-mile, 11-hour test drive of the system — and putting my life in its hands without my hands on the wheel — I sat down with Daryl Wilson, lead development engineer for Super Cruise, to get a deep dive into the system and its critical safety backups. Autoblog: First, what makes Super Cruise different from similar systems? Wilson: The key differentiator for Super Cruise is hand-free driving. It's an industry first in that respect. Our competitors require the driver at minimum to place their hands on the wheel with some frequency to ensure that the car knows that the driver is there. We don't. Two key technologies allow us to do this. One is our Driver Attention System, which is our methodology for making sure the driver is engaged with the vehicle and engaged with the road. This is a driver assist system, not a fully autonomous system. So it requires driver engagement. We use an infrared camera that constantly monitors the driver's face to determine the direction they're looking. We're looking for the driver to be what we call on-road — not on the center stack, not to left or right or down. That's all done by the tracking of the face. We also track that the eyes are open. It's infrared because at night you need to illuminate the face and you can't be shining a light into the driver's face. Then we have our lidar mapping that provides a foundation for control and redundancy to ensure safe performance. Autoblog: How does the mapping act as a redundant feature? Wilson: This system is only for use on divided, controlled access highways. What I mean by a divided highway is something more than a painted line between you and oncoming traffic. Whether that's a grassy area in between the lanes or a concrete barrier, anything that separates you from oncoming traffic. That's the divided highway part. The controlled access part is entrance ramps and exit ramps. Not with roads that cross at grade, with traffic crossing at the same level. To do that we geofenced these roads to ensure that operation is only allowed in these conditions. We don't just recommend you use it there; we ensure that you only use it there.

2020 Cadillac XT4 Sport Drivers' Notes | Worth a look, or two

The 2020 Cadillac XT4 is Cadillac’s smallest crossover in its burgeoning lineup of SUVs. Most of the attention is on the new Escalade these days, but the XT4 is where someone with a lighter budget might enter the Cadillac brand. Our tester happens to be the Sport model, giving it a distinctive appearance, separate from the Luxury and Premium Luxury trims. This one has a gloss black mesh grille, black trim throughout the exterior and Sport-specific wheels — the others rely much more heavily on chrome. Cadillac stepped it up in the design studio for the XT4, as one of its best qualities is the exterior design. It compares well to other small crossovers and doesn't look like your typical cookie-cutter crossover on the road. ThereÂ’s only one engine available, and itÂ’s a 2.0-liter turbocharged four-cylinder that makes 237 horsepower and 258 pound-feet of torque. When the XT4 came out for the 2019 model year, this engine was brand new. Today, Cadillac is passing it around the lineup to vehicles like the CT5 and CT4. A nine-speed automatic transmission is the only transmission option, as well. Our tester has all-wheel drive, but front-wheel drive is standard on lesser XT4s. There isnÂ’t a whole lot changed for the 2020 model year, but Cadillac did add an “Off Road” mode and made a bunch of safety equipment standard. With our test car being a Sport trim with all-wheel drive equipped, the base price is $42,295, a fair bit greater than the $36,690 standard car. After options, our XT4 totaled $48,310. The most expensive extra is a $1,500 Bose Centerpoint audio system, combined with navigation. An $1,100 Driver Assistance package brought adaptive cruise control, enhanced automatic emergency braking and reverse automatic emergency braking. A Cold Weather package added heated seats all around and a heated steering wheel for $850. Finally, the $470 Driver Awareness package brought automatic high beams and lane-keep assist. Senior Editor, Green John Beltz Snyder: This one grew on me the more I drove it. I was unconvinced for the first part of my drive, but then things started to feel more well-though-out as I used them. For instance, the line of buttons across the center stack looks daunting, until you turn the car on and their labels are illuminated. Then everything is easy to find thanks to the lighting, symmetry and the fact that you only have to look down a single line of buttons rather than hunt around a grid pattern.

Watch the 2019 Autoblog Technology of the Year presentation to Cadillac

Autoblog presented our 2019 Technology of the Year Award to Cadillac at the Detroit Auto Show. Autoblog conducted rigorous testing last fall on the latest automotive technologies, and Cadillac Super Cruise earned top honors, edging out Infiniti's Variable Compression Turbo and Mercedes' EQ technologies, the other two finalists. Super Cruise is a semi-autonomous system that allows for hands-free driving to reduce the driver's workload. Our editors found it easy to use and noted the system simply works as intended. We happily found Cadillac under-promised and over-delivered with Super Cruise, a clever system that truly helps the driver. Super Cruise launched on the CT6 sedan, and Cadillac plans to roll out the feature to other vehicles. Watch the video above as Cadillac President Steve Carlisle receives the 2019 Autoblog Technology of the Year Award from Editor-in-Chief Greg Migliore, with Autoblog GM Adam Morath and the editorial team on hand at the Detroit show.
