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 CT6 gets a plug in Shanghai, will come to US

Don't call it the third coming of the Chevy Volt. The unsurprising debut of the Cadillac CT6 PHEV in Shanghai today has a powertrain that sounds an awful lot like the one that can be found in the Volt and the Cadillac ELR. The plug-in CT6 – identical to the CT6 that debuted in New York earlier this month – has an 18.4-kWh lithium-ion battery (just like the 2016 Volt) and offers an all-electric range of around 37 miles. It also copies the "Regen on Demand" feature from the new Volt and the battery cells "use the latest generation cell chemistry found in other GM plug-in vehicles." But Cadillac President Johan de Nysschen doesn't see the two powertrains as similar in at least one important way. General Motors calls the Volt and the ELR "extended range electric vehicles" (EREV) but in a statement, de Nysschen says that the plug-in hybrid CT6 is, "an ideal platform for Cadillac to offer its first plug-in hybrid." That GM is using the PHEV terminology rather than EREV is going to be important to some, even if the practical difference is only semantic. And yes, we all understand the irony of de Nysschen – the same guy who has a history of speaking ill of plug-in cars – hyping them now. Back when he worked for Audi, he said the original Volt was too expensive for what it offered and was thus, a car for "idiots." Speaking in Shanghai today, de Nysschen said the new CT6 PHEV was, "an EV without any of the disadvantages or range constraints," according to Automotive News. If the batteries are similar to GM's other EREV/PHEV cars, the CT6 powertrain is at least different. The ELR uses a 1.4-liter engine, while the new Volt has a 1.5-liter four-cylinder mill. The CT6, on the other hand, has a 2.0-liter turbo four-cylinder engine with direct injection. There is also an "all-new rear wheel electric variable transmission (EVT) with exclusively designed motors," that will give the CT6 PHEV, "smooth, spirited acceleration." The EVT is a two-motor-unit that uses three planetary gears. Maximum overall system output is 335 horsepower and 432 pound-feet of torque. Perhaps most interesting for American audiences is the fact that GM's press release, available below, makes multiple references to US-market sales of the PHEV. Official details on the EV range and fuel economy will be made available closer to the car's US launch.

Alonso's Cadillac team wins 2019 24 Hours of Daytona

Two-time Formula One champion Fernando Alonso won the rain-shortened 24 Hours of Daytona, overhauling Felipe Nasr two laps from the eventual finish on Sunday. The Spaniard became only the third Formula One champion to win the race, joining Phil Hill (1964) and Mario Andretti (1972). "It's amazing," Alonso told NBCSN. "Just an amazing experience with this team, from the test and now the race –- a perfect execution of the race. "Very different conditions and we've been competitive in everything –- dry, wet, night and day. Really happy for the team and all the guys." Alonso, who retired from Formula One racing after the 2018 season, said the victory would rank very high among all his accomplishments. "To win this kind of endurance racing at iconic places like Daytona means a lot," he said. "With zero experience and background in endurance before (last year) it's quite a big thing." Already the winner of last year's 24 Hours of Le Mans, the 37-year-old Alonso will attempt to complete the Triple Crown of motorsports by capturing the Indy 500 in May. Driving the Wayne Taylor Cadillac DPI, Alonso took command of the race for keeps when Brazilian Nasr failed to navigate turn one and drove into deep water, losing a 1.5-second advantage. By the time Nasr had things under control, Alonso was 12 seconds ahead. Kamui Kobayashi, Jordan Taylor and Renger vanDer Zande teamed up with Alonso for the victory in his second try in the 24-hour race which was twice red-flagged because of rain and water on the track and was halted 10 minutes early. "With all the rain, I've never seen a race like this," Team Penske boss Roger Penske told NBCSN. Alexander Rossi was the only other driver to finish in the lead lap. He took third. Italian Alex Zanardi's return to endurance racing 17 years after he lost both legs in a horrific race wreck got off to a bad start 90 minutes into the race, At the beginning of his first stint driving, Zanardi encountered a problem with his steering wheel. The 52-year-old was using a special wheel with hand controls for the car, and the connecting pins were damaged when he attempted to connect it as the car was dropped from the jack. His No. 24 BMW Team RLL team finished 32nd overall and ninth in class. Full results. Related Video: Featured Gallery 24 Hours of Daytona 2019 View 20 Photos Motorsports Cadillac daytona
