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.

All-new 2019 Cadillac XT4 crossover debuts in New York

Cadillac spent years and years improving its mainline sedans, the CTS and ATS, turning them into awfully good impressions of BMWs from a few years before. The thing is, great sedans aren't selling, and crossovers sure are. Cadillac's XT5 is the only crossover in the lineup, something that's had American Cadillac dealers gnashing their teeth and wailing — although anyone they can upsell into an Escalade can staunch the bleeding. That brings us to the new XT4, which is smaller than the XT5 but even sharper than its bigger sibling. Let's take a closer look at this new two-row luxury crossover. For one, it's based on what Cadillac calls a unique platform. That may be true, technically, although it's likely related to the Equinox/Terrain on some level. Platforms are becoming quite flexible: Look at Volkswagen's MQB, under everything from Euro hatches smaller than our Golf to the three-row Atlas. Whatever else it is underneath the skin, all XT4s will share one powertrain: the corporate 2.0-liter turbocharged inline-four, paired to a nine-speed automatic transmission. View 14 Photos The engine puts out a healthy 237 horsepower and 258 pound-feet of torque, putting it just a hair underneath its closest domestic rival, the Lincoln MKC with the 2.0-liter EcoBoost. Of course, the 2.3-liter MKC beats the XT4 handily, but that's another story. Power is produced with the help of a twin-scroll turbocharger. All-wheel drive is available, with a driver-selectable rear axle disconnect to save a small amount of rolling friction. Cadillac estimates it'll be good for 30 MPG on the freeway, but we haven't seen official results to confirm that. A few other changes that'll affect driving: electro-hydraulic brake assist, a first for Cadillac and mainly a fuel-saving measure; and Continuous Damping Control, which alters the damper's valve continuously based on a number of parameters. It's almost certainly used here because it's lighter and less expensive than air suspension or MagneRide, and it is optional on XT4. CDC or no, all XT4s utilize a front strut and five-link rear suspension. All XT4s also ride on 18-inch wheels in various designs. The trim strategy is mildly interesting. The base model is the Luxury, and then you can choose a Sport (black exterior trim, unique wheels) or a Premium Luxury (bright trim and satin-brushed accents). The interior options are suitably upscale and premium, and we'll have more to say about them a little later when we can see this car up close.

Akerson says Cadillac will get a larger sedan within two years

It seems that during a recent affair showing off the 2014 Cadillac CTS, General Motors CEO Dan Akerson confirmed reports regarding a new Cadillac flagship sedan. According to USA Today, which Akerson was visiting, he said that a sedan larger than the XTS would debut within the next two years.
This matches up with what we heard earlier in the month about a Cadillac model that will go up against the BMW 7 Series and Mercedes-Benz S-Class (not a pricier, low-volume sedan also discussed in that article). But this is the first time a high-profile executive name has been attributed to such a report, and the first time a broad timeframe has been mentioned. This article adds that the unnamed car will be rear-, and all-wheel drive with a platform "loosely based" on the new CTS, with styling closer to that car than recent Cadillac concept vehicles. The XTS will continue production of course, as well.
