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.

2015 Cadillac ATS-V gunning for the BMW M3

Spy photographers have spotted something interesting. Cadillac engineers have taken to public streets with the upcoming ATS-V and a playmate: the current BMW M3 Sedan. The prototype seen here wears a more aggressive front fascia, flared fenders and beefy brakes. Quad exhaust tips and what looks to be a small lip spoiler on the trunk deck sum up the most obvious visual changes over the standard ATS outside. Word has it the ATS-V will bow with the same twin-turbo 3.6-liter V6 available in the nose of the XTS. In that application, the engine is good for a stout 410 horsepower, which should be more than enough to hustle the sedan around a track.
Other details are still murky, however. First and foremost: will GM offer the ATS-V with an honest manual transmission, like it does with its big brother, the CTS-V? Something tells us we won't have long to wait to find out - the machine will likely bow next year as a 2015 model. Until then, dig in on our newest bevy of spy photos.

Cadillac CT5 Luggage Test | How big is the trunk?

The Cadillac CT5 is a midsize luxury sedan. At least by today's standards. By the standards of Cadillac's past, it's practically a compact. At 193.8 inches long, the CT5 is 3 inches shorter than its STS predecessor of 15 years ago and 11 inches shorter than the Seville of 25 years ago. This is significant since virtually every other car brand's offerings have grown from generation-to-generation. See the BMW 5 Series as just one example. You'd have to go back to the 1980s to find a CT5 ancestor that's smaller, though that stubby thing was an aberration.   Honestly, I'm just sharing that because I think it's interesting. This post is about trunk space, and exterior size doesn't necessarily equate to how much junk you can fit in the trunk. In fact, the CT5 is pretty good example of that. Although smaller than its predecessors, the CT5 is still an awfully big car that's comparable to other midsize luxury sedans, including the 5 Series, Audi A6 and Mercedes-Benz E-Class. The trunk, however, is notably smaller than what you'd get in those with a rather rinky-dink 11.9 cubic feet. That's coupe territory and less than what you'd get in some subcompact sedans. The A6 and E-Class are in the 13-cube range, while the 5 Series apparently has 14.5 cubic feet.  So, how small is 11.9 cubic feet? Although plenty wide at the rear, which should be handy for golf clubs, the CT5's trunk isn't very long compared to all those competitors. The A6's is narrower but also practically a tunnel by comparison. Also, note the ramp-like structures along the outer edges. Besides making loading a hassle, they effectively make the trunk even smaller than the 11.4 cubic-feet that's technically there since it's so difficult to load items right up to the wheel wells. You can see a closer look at those "ramps" above left along with the smallish pass through that oddly looks like a previous-generation Hyundai Sonata's grille.  Above right you can see the underfloor storage. There is no spare tire.  Besides those "ramps" impeding luggage loading from below, these giant speakers hanging down from the parcel shelf sure don't help, either. Watch your hands while loading, as well as anything that might be easily scratched (or that might damage the speakers) OK, let's get to the bags.
