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.

Porsche 911 Turbos, and the new Lotus Emira | Autoblog Podcast #686

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Road Test Editor Zac Palmer. The two talk about their experiences in the 911 Turbo and Turbo S Cabriolet, then pivot to talking about the BMW M3 Competition on the Indiana Nurburgring. They follow that up by discussing driver assistance systems, given recent experience in the 2021 Cadillac Escalade with Super Cruise and Hyundai's Highway Drive Assist. After that, they get into some news, talking about the new Lotus Emira and Genesis G80 Sport. Finally, they wrap up with a rather interesting two-for-one "Spend my Money" edition where they help two listeners with different car buying conundrums.

Cadillac ATS sedan is in its last year

Cadillac has just confirmed that the ATS Sedan dies at the end of the 2018 model year. In an e-mail to CarBuzz, spokesman Donny Nordlicht wrote, "Production of the ATS Sedan is ending due to extensive plant upgrades, expansion and re-tooling to prepare for the next generation of Cadillac sedans." The admission confirms several months of deduction based on a document trail put together by The Truth About Cars. Last December, TTAC reported that General Motors didn't list a 2019 Cadillac ATS sedan on VIN documents submitted to the National Highway Traffic Safety Administration. Only the coupe remained, the presumption being that 2018 would be the last year for the sedan. That presumption was bolstered by industry sleuth Bozi Tatarevic's discovery this week that GM hasn't included the ATS sedan in the carmaker's fleet order guide. The death of the four-door ATS won't surprise anyone paying attention to statements from Cadillac or ATS sales figures. Brand then-president Johan de Nysschen strongly hinted last summer that three sedans would bite the dust come 2019, and one would be refreshed. We've seen the gussied-up CT6, so that put the XTS, CTS, and ATS in the funeral home. The XTS would die an unavenged death, while the CTS downsized into the properly midsized CT5 and targeted buyers in the $35,000 to $45,000 range, overlapping with $34,595 ATS sedan pricing by doing so. The ATS would go on hiatus, eventually resurrected as a compact luxury offering possibly called CT3 in coupe form and CT4 as a sedan sometime around 2020. As for the market situation, ATS sales are up 7.3 percent in the U.S. through the end of April this year compared to 2017. However, the ATS sold only 13,100 units in the U.S. in 2017, compared to 21,505 units in 2016 and a high of 38,319 in 2013, its first full year on sale. Assuming new Cadillac president Steve Carlisle stays the predicted course, GM might keep the ATS Coupe as a lure to sporty buyers in the segment until a possible CT5 coupe arrives. Otherwise, Nordlicht's e-mail said "Cadillac's future sedan portfolio will consist of three sedans, positioned in different segments and clearly differentiated by size and price." The 2019 ATS Coupe will stick with its three current engines, the 2.0-liter turbo with 272 horsepower and 295 pound-feet of torque, the 3.6-liter V6 with 335 hp and 285 lb-ft, and the 3.6-liter twin-turbo V6 in the ATS-V with 464 hp and 445 lb-ft of torque.
