Cadillac's semi-autonomous Super Cruise pushed back to 2017

It looks like General Motors is discovering just how difficult it is to bring autonomous vehicle technology fit for public consumption to market. The company has pushed back the launch of its semi-autonomous Super Cruise technology by several months. Originally promised by CEO Mary Barra for a fall 2016 debut, Super Cruise was supposed to be offered first on the new CT6 sedan. Automotive News is reporting that won't be the case, following a statement from GM confirming that the new system would be pushed to sometime in 2017. At the very least, that's a several month delay. GM cited the need to get the system right and keep owners safe, which prevented a firm date for Super Cruise's debut. Product boss Mark Reuss was more blunt, though, telling AN, "It will come out when it is ready." Super Cruise would be one of the earliest examples of driverless tech to be put into public hands, following the introduction of Tesla's semi-autonomous AutoPilot system in 2015. Most other automakers experimenting with the autonomous vehicles don't foresee public sales until early in the next decade, including Toyota, Renault-Nissan, and Volvo. Before Barra suggested a 2016 debut, GM originally aimed to introduce its semi-autonomous system in 2020. Related Video:

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 XT5 platform to underpin three-row crossover

Cadillac just launched the XT5 crossover to replace the SRX. But that's only the start. Speaking with Automotive News, Caddy president Johan de Nysschen confirmed that a new three-row crossover is also on the way. The seven-seater is based on a stretched version of the flexible platform underpinning the XT5, which we just drove recently. Taking that approach will give the luxury brand a larger crossover to pit against the likes of the Infiniti QX60, Audi Q7, and Volvo XC90 without having to develop one from scratch. It will also give buyers a more car-like alternative to the larger, truck-based Escalade. "It's one of the benefits of having this very flexible architecture. We can expand it, make it longer and wider. That gives us the ability to develop the car very quickly, as opposed to starting from scratch," de Nysschen told AN. "It's not running yet. It is a program request that we initiated with the engineers only last year. They are working at remarkable, record-breaking speed to get us the car." The new model would likely be called the XT7 and offer similar levels of equipment to the existing, smaller XT5. The existing mid-size model packs a 3.6-liter V6 mated to an eight-speed automatic transmission and comes in four trim levels. Related Video:
