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.

BMW reclaims US luxury sales crown from Mercedes

The numbers, they are in: BMW has reclaimed the luxury-sales crown from Mercedes by a margin of 9,347 cars. Mercedes donned the king's headgear in 2013 after a strong final quarter of 2013 when the new CLA and S-Class poured out of dealerships. This year, led by the 3 Series/4 Series and X5, BMW sold 339,738 units – a 9.8-percent increase year-on-year. Mercedes, led by the C-Class and M-Class, saw its sales go up by 5.7 percent to 330,391 units. We'll have to wait a bit to see if there's another registrations-vs-sales challenge as in 2012, when BMW was anointed US luxury ruler. Behind them, a dark horse named Lexus nudged closer to the leading Teutons, selling 311,389 cars. The Japanese luxury automaker also had the biggest gain among the top three, its sales rising by 13.7 percent compared to 2013. Audi had the biggest sales of anyone among the top five, though, with a 15.2-percent gain to 182,011, which moved it a spot ahead of Cadillac; the Wreath-and-Crest brand dropped 6.5 percent to 170,750. Acura (167,843), Infiniti (117,300), and Lincoln (94,474) took the final positions. Speaking of Lincoln, sales at the once-mighty luxury marque stand as the mightiest jump of any on this list, up 15.6 percent. That's the power of Matthew McConaughey... and better cars and a new crossover, sure. So now that we're back to Round One of 2015, in case no one else has said it yet: "Ok, fight!"

Mystery Cadillac coupe concept revealed in patent drawings

We have been reminded once again that when Cadillac designs a coupe, it's usually spectacular. The reminder comes in the form of a patent drawing filing that was previously reported on by Jalopnik. In the filing are shots of the two-door from just about every angle, and there's not a bad one in the bunch. Unfortunately, there isn't really any other information about the car in the patent, so the car remains a mystery in that regard. Still, there's a fair amount to be gleaned from the images. It certainly looks sportier than most recent Cadillac concepts. It has a fastback roof and a short deck lid. The rear bumper has a diffuser design fitted to it. The rear fenders are very wide. It has large auxiliary grilles on each side of the center one, and the way the taillights are designed seem to hint at extractor vents. The overall proportions even look a bit like those of the Camaro, but possibly a little larger. The car also looks like it's probably a concept. The side mirror stalks are far too skinny to actually be production units. The big diffuser and center exhaust, plus those rear extractor vent designs seem a little much for a production model, too. The headlights are also a little on the small side. Being a concept (probably), we're a little worried. We really want to see this thing come to market, but Cadillac has a bad track record of showing beautiful concepts that never make it to production, even when they aren't particularly over-the-top. The Elmiraj and Ciel are two that come to mind. The former was a coupe, too, and was elegant and grounded. We never got a production version of either. We did see some styling inspiration from the Elmiraj on the ATS and CTS, but they never quite captured the concept's beauty. Then again, when Cadillac has managed to bring a recent concept to production, the results haven't great. The Converj concept became the ELR, and while the styling came through fine, it was hampered by an uninspiring powertrain and an excruciating price tag. But hey, Cadillac could always prove us wrong. And we would like them to.
