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.

Is Cadillac working on an ELR-V? [w/video]

Could it be? Could Cadillac be working on an even higher-end version of its ELR plug-in hybrid? Well, General Motors' Executive Vice President Mark Reuss has gone on record as... well, not saying much. The exec was more than a bit coy on video (which you can view below) when asked about the idea of an ELR-V, although he did say that Cadillac was looking at "expanding the tuning envelope" for its plug-in coupe. What that means could be hinted at in these spy photos.
Cadillac is certainly up to something with this little red ELR. As is often the case, it's the car's enhanced brakes that give it away. Bigger binders are a telltale sign of sportier aspirations, and it's safe to say that rule applies with the ELR. The larger rotors and four-piston Brembo calipers are sourced from the Buick Regal GS, which we imagine would be plenty to bring the high-priced hybrid to a halt.
Obscuring those rotors and calipers are larger, double-armed five-spoke wheels. And, according to our spies, hiding behind that camouflage is a new grille. Outside of those two items, though, there's not much aesthetic change.

Beast mode on the open road: New presidential limo close to delivery

Signs of the Beast have been seen on the open roads around Milford, Mich., home of GM's Proving Grounds. The Beast, in this case, being the nickname for the next-generation presidential limousine. We've seen this car previously in spy shots while parked or driven, going back to January 2016. This is our spy photographers' latest look at the vehicle, and the first on public roads. Which may be a sign that it is almost ready for delivery. It replaces the current Beast, which has been in use since 2009. And "car" isn't exactly the right word for this rig, as it's actually a unique vehicle with Cadillac styling cues custom-built atop a medium-duty truck frame. There may possibly be more than one Beast 2.0 delivered, because two limos are sent anywhere the president goes, to provide a backup or decoy. The grille has touches of the Cadillac Escala concept car, which is heavily influencing Cadillac's evolving future look. But it's what's inside that intrigues everyone. Here's what we know, or at least has long been rumored, about the current Beast and the new Beast 2.0. 1. It has its own airplane. It and its twin follow the president around the globe aboard a C-17 Globemaster cargo plane. 2. It's heavily armored, with 5-inch-thick glass, 8-inch-thick doors that weigh as much as a commercial aircraft door, and its components include titanium, ceramics, and a bombproof plate that covers the underside. As such, the old Beast was estimated to weigh between 14,000 and 20,000 pounds. You can therefore imagine how it got its name. 3. It's equipped like the Batmobile or the Green Hornet's Chrysler Imperial Crown, with run-flat tires and night-vision gear. It can fire gas canisters out the front bumper. 4. It has a diesel engine because of its weight and size (see the gallery below for a sense of scale). And of course, diesel is less flammable in a firefight. The old Beast supposedly gets 8 mpg. 5. Its Secret Service codename is Stagecoach. 6. There's a shotgun by the driver and God-knows-what in the trunk. 7. It supposedly has a stock of blood in the president's type, along with a defibrillator and other emergency gear. 8. And it's pretty nice inside, by all accounts. Since this is not Trump's own personal vehicle and may well serve his successor, let's assume the gold leaf has been kept to a minimum and it's done up in tasteful leather and wood. But then again, who really knows, outside of the Secret Service and a handful of GM engineers.
