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.

Cadillac Lyriq teased ahead of debut next week

The Cadillac Lyriq is just around the corner, set to be fully revealed on August 6. Cadillac just released a few teaser photos and videos as preparation for the big debut a week from today. It’s our best look at the production version of the car yet. Of course, you may remember photos of the EV concept released over a year ago, but the production crossover is shaping up to be a little different. This carÂ’s most intriguing element so far is the charge outlet panel integrated into the front fender. The large piece appears to lift up and slide out of the way when itÂ’s time to plug in. This reveals a decorative LED light strip that outlines the outlet, ultimately leading into the Cadillac logo above. Below the panel is a small, silver GM badge that if our guess is correct, says “Ultium” for the Ultium battery technology going into the Lyriq.  The wheels feature a unique silver and black two-tone design. Those black inserts are ridged, and the wheel is likely designed for better aero performance and increased range. ItÂ’s tough to say much about the design itself, but the silhouette is giving us crossover coupe vibes with its heavily raked rear window and sloping roofline. It appears to have a couple spoilers, one on the roof and then another as a ducktail below the rear window. CadillacÂ’s video teasers provide for the briefest of front end glimpses. Still, we can see the fancy lighting signature that Cadillac has created. ThereÂ’s both a light-up Cadillac badge and small LED lighting strips integrated throughout the grille. ItÂ’s concept car-like in appearance, so we do wonder whether this will find its way into a production Lyriq. The vertical DRL weÂ’re used to seeing on other Cadillacs has also made an appearance on the outer edges of the front bumper. ItÂ’s been previously stated that the Lyriq would enter production in 2022, so even when GM does reveal the electric Cadillac next week, itÂ’ll be a long while till we see the vehicle on the road.

MIT puts V2V technology on its 2015 Top Ten list

Of all the technologies swimming around the automotive world, it is vehicle-to-vehicle communication that the Massachusetts Institute of Technology has fished out as one of its Ten Breakthrough Technologies of 2015. It joined emerging tech like brain organoids, supercharged photosynthesis, and Project Loon on the list, and got the nod over autonomous driving because, as the MIT Technology Review wrote, V2V communication "is likely to have a far bigger and more immediate effect on road safety." How so? Because actual cars transmitting data like their location, speed, steering angle, and state of braking to one another at least ten times per second provides a greater degree of awareness than sensor readings and algorithms. The US Department of Transportation and the National Highway Traffic Safety Administration have been working for years on standards and a regulatory schedule for introducing V2V to the marketplace, and Cadillac plans to incorporate V2V into at least one of its vehicles by 2017. Since we've begun the year with a number of stories of cars being hacked into, that got us wondering about the security of V2V communications. In a recent piece by our own Pete Bigelow on what motorists should know about getting their cars hacked into, he wrote that although cyber break-ins are extremely difficult, expensive, and time-consuming to do remotely, V2V is "one more conceivable avenue a hacker could use to impact multiple cars at a given time." So we spoke to Wilmington, Massachusetts-based Security Innovation about it. The automotive consultancy company has been working with the DOT since 2003 on V2V technology and the issues around it - namely security and privacy - and its chief scientist, William Whyte, is the technical editor of the Institute of Electrical and Electronics Engineers (IEEE) 1609.2 standard outlining its security protocols. Those protocols are expected to be finalized by the DOT toward the end of this year and then come into effect in 2016, and the company's Aerolink product is the security solution Cadillac will use. Whyte said, "If you hack into a car, V2V is the hardest place to start," and Pete Samson, the general manager of Security Innovation's automotive team, said "There are ten or 12 alternate attack surfaces" around the car that would make much easier targets.
