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 president Johan de Nysschen expands on brand's future

Cadillac president Johan de Nysschen chatted with journalists at a recent roundtable, expounding on everything from domestic racing to Chinese manufacturing. The brand's been doing a slow burn on rolling out new products and increasing sales, but admittedly, there was a lot of work to do. After closing out last year 0.8 percent down in the U.S., the domestic luxury brand is more than 5 percent up so far this year, thanks to healthy double-digit bumps for the ATS and Escalade, and increased fleet sales. Globally, the brand's doing 21 percent better. The XT5 still outsells everything, though. Asked about slow sedan sales, de Nysschen cited a few reasons, one of them "energy prices," which are low enough to fuel the crossover craze. You can also read that as another admission that Cadillac doesn't have enough crossovers to please the crowds, a fact the XT4 will soon address. Yet de Nysschen also pegged the sedan malaise on "younger consumers who really are less tuned into dynamics and handling and all of those things that used to excite enthusiasts. It's more about the way cars complement and enable their lifestyle now." He topped that with a take on U.S. roads, saying, "I also have to say it may also be influenced a little bit by the decay of America's infrastructure. When roads no longer support high-performance sport sedans and ultra-low-profile rubber, people are going to respond to it." Those latter takes seem wide of the mark. Yes, BMW is the established leader, but the Munich carmaker sold 8,806 3 Series' so far this year in all variants, compared to 2,543 ATS coupes and sedans. Mercedes-Benz has sold 8,366 C-Class models so far in all variants. As for infrastructure, yes, it's a mess, but AMG sales rocketed up nearly 50 percent in the U.S. last year, nearly 10 percent of overall Mercedes sales, and the Three-Pointed Star expects that to rise again this year. People are buying sedans and performance models. They simply aren't buying enough of them with Cadillac badges. Cadillac has no plans to go racing in Europe since the brand doesn't have the kind of presence there to justify the investment. De Nysschen said they'll stick with the Daytona Prototype International formula in the U.S. domestic scene, and continue with the tech transfer from race to road.

Cadillac is returning to endurance racing with a new prototype in 2017

In two months, Cadillac will return to top-tier endurance racing with its all-new Daytona Prototype International racecar after 14 years away. The car, which adheres to IMSA's new DPi regulations, looks as long, low, and Cadillac-like as anyone could have hoped. It's set to debut at the Rolex 24 at Daytona and will compete head to head with the likes of Mazda and Nissan in what is shaping up to be one of the most diverse and exciting forms of American motor racing in years. The new car will be run by Wayne Taylor Racing, the team that previously fielded the Corvette Daytona Prototype. Wayne Taylor himself has won the 24 Hours of Daytona twice, in 1996 and 2005. He now manages the team and leaves the driving duties to his two sons, Ricky and Jordan. They'll be joined in the cockpit by Max Angelelli, Wayne Taylor's teammate in 2002 at Cadillac's last unsuccessful attempt at endurance racing. To understand Cadillac's new car, officially called the DPi-V.R., you need to understand IMSA's DPi category. Basically, manufacturers are allowed to base their car on one of four chassis that follow the FIA LMP2 regulations. The chassis come from either Dallara, Onroak Automotive, ORECA or Riley/Multimatic. Cadillac will base their car on the Dallara platform. The DPi regulation differ from the LMP2 in two major ways: non-standardized engines and the ability to change certain parts of the bodywork. The DPi regulations are intended to give the variety of the top-tier LMP1 cars at a fraction of the cost. When it came to choosing an engine, Cadillac wanted to power the new car with something kinda sorta production based. The new car will use a naturally aspirated 6.2-liter pushrod V8 that shares some base architecture with the engine in the current CTS-V. While the power output hasn't been announced, expect about 600 horsepower. While that's down compared to the CTS-V, there is far less mass to move around as the Dallara chassis is a svelte 2,050 lbs. Since all the teams will be running different engine configurations, expect restrictors of some sort to help balance the power disparity. The parts of the body work that can be modified - The nose, sidepods, rear wheel arches and rear valance - have all been designed to mimic Cadillac roadcar design elements. Even the wheels look like they were pulled straight from the CTS-V. The front splitter, the floor, and the diffuser are common elements shared with other DPi cars.
