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.

Cadillac previews upcoming new XT5 crossover [UPDATE]

UPDATE: Cadillac has released another three images, which we've added to the gallery above. Cadillac is gearing up to unveil its new XT5 crossover at the Dubai Motor Show in November. We've already seen what it'll look like - from a couple of angles, anyway - but the all-American luxury automaker has given us another taste of what's to come with a quartet of images released on its official Facebook page. Set to replace the SRX that's now six years old, the all-new XT5 adopts the new design language we've seen on newer Cadillacs of late. That's most particularly emphasized with those vertically integrated LED headlights. The sharply creased styling is also signature Cadillac, as is the egg-crate grille capped by the brand's wreath-less new emblem. The dark brown paint job also looks like it has a deep metallic flake to it, offset by satin brightwork where you might have once expected to see glinting chrome. (Then again, it could just be reflecting a uniform backdrop.) The XT5 is expected to be the first of several new Caddy crossovers to wear the letters XT. A smaller model (likely to be dubbed XT3) is tipped to slot in below, with a larger XT7 to slot in above – but still below the defiantly truck-based Escalade that's not about to go anywhere anytime soon. Sedans will continue to start their nameplates with the letters CT. But after a dozen years, the letters SRX will be retired from the Cadillac lexicon. Related Video:

The Cadillac Of Stopgaps
As confusing as most alphanumeric car names have gotten in recent years, at least one constant has been that the letter "X" is generally indicative of a crossover. Then why did General Motors use this letter on its new 2013 Cadillac XTS luxury sedan? Well, for that, we'll have to look to the world of mathematics where "X" stands for an unknown variable or a placeholder. Now we're talking. The XTS is just an interim product sitting at the top of Cadillac's four-door food chain until the brand gets a true flagship in place. That sounds like a lot of resources to spend on what will likely be a one-and-done model, but the automaker needed to get something - anything - to replace the DTS.
So here you have the 2013 XTS. A big luxury sedan that was created to bridge the gap between Cadillac's recent past and its pending future. Going into our week with this XTS knowing that it was a stopgap measure proved to be both a blessing and a curse. On one hand, we know (or hope) that this car will act as a baseline for future high-end Cadillac models, but at the same time, we couldn't help but be mindful of past stopgap models, albeit in more entry-level segments, like the Cimarron and Catera.
