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 CT6 refresh has hints of Escala

Almost a year after Cadillac showed its stunning Escala concept at Pebble Beach, we're finally seeing some of that car's influence on production cars. These spy shots reveal that the CT6 will undergo a mild refresh, and despite the camouflage, we can make out details that show it will have looks more in line with the concept. One of the defining characteristics of the Escala were narrow, horizontal headlights, while the current CT6 has long, vertical lamps that go up the tops of the fenders. This prototype seems to split the difference. The bases of the lights terminate higher up on the fascia, emulating the Escala, but still travel up the fenders. It also appears that the LED accent lights remain, but it's possible they've been separated from the main lamps to become more like the concept. The grille has also been revised. It's hard to make out the exact shape, but the insert is the same type of mesh as the Escala's, with little highlights that look like miniature Cadillac crests. The full-size, full-color crest also appears to sit higher in the grille, which is another nod toward the concept. The lower grille in the front bumper also looks larger and more angular. That doesn't really lean toward either model, but should give the car an edgier look. The rest of the car looks generally the same as the current model. Even the tail shows little indication of changes. It's possible that the rear taillights could have an Escala-like horizontal section at the top of the trunk lid, but there's nothing visible on this prototype that would confirm that change either way. Since this is a relatively mild refresh, we would expect to see it fully revealed early next year. Related Video:
