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.

Cadillac abandons plans for six-digit flagship sedan

So much for that party. Cadillac has announced that it is walking away from plans to build a high-dollar, rear-wheel-drive ultraluxury sedan. The low-volume model would have been based on the lusty Ciel Concept, and the production iteration would have carried a price tag well over $100,000. Executives with the automaker reportedly claim the model wouldn't have bolstered the brand enough to be worth the investment.
Even so, Automotive News reports Cadillac is still on track to build a range-topping four-door to go head-to-head with the BMW 7 Series and Mercedes-Benz S-Class. That model will likely be constructed on the company's upcoming Omega rear-wheel-drive platform, but we won't see it bow until at least 2016. Right now, the front-wheel-drive XTS sits at the top of the Cadillac lineup, and while that machine and it's twin-turbocharged V6 variant makes a compelling argument against certain luxury entries, it falls short serving as a legitimate competitor for the likes of the 7 Series and S-Class for enthusiast drivers.

2019 Cadillac XT4 vs. other compact luxury crossovers: How they compare

After years of every other luxury car maker stocking their showrooms with trendy crossovers, Cadillac is finally joining the fray. Its latest addition is the 2019 Cadillac XT4, a tidy little crossover that proudly bears signature Caddy designs such as the tall slender taillights. And based on our first drive of the car, it impresses in many ways, such as its refined engine, classy interior and excellent ride quality. View 39 Photos That's good news for the little Cadillac, but it needs to stand out in a big segment. To see if it has any other areas where it shines, or maybe some where it's a bit dim, we decided to compare its specifications with those of four of the segment's bestselling compact crossovers, the Lexus NX 300, Acura RDX, Audi Q5 and BMW X3. And for good measure, we threw in the XT4's crosstown rival, the Lincoln MKC.

And don't be afraid to check these cars out in person at their respective dealerships. Engines, transmissions and fuel economy With the exception of the Lincoln MKC's optional 2.3-liter engine, every competitor here resorts to the same type of engine, a turbocharged 2.0-liter four-cylinder, for its propulsion. And unsurprisingly, they make similar power, in the mid-200 horsepower and mid-200 lb-ft of torque range. Of the 2.0-liter engines, the standout is the Acura RDX, which produces a hearty 272 horsepower and 280 pound-feet of torque. It's second in power only to the Lincoln's optional turbo 2.3, which makes 285 horsepower and 305 pound-feet of torque. The bottom of the pack is the Lexus with 235 horsepower and 258 pound-feet of torque, but the next least powerful crossover is the Cadillac XT4, with just two more ponies than the Lexus, and the same amount of torque. View 22 Photos Though the Cadillac is nearly the least powerful, it does get to claim the best fuel economy numbers, rated at 24 mpg in the city, 30 on the highway, and 26 combined with front-wheel drive.
