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.

What are the odds an actual Cadillac EV looks anything like this?

The Cadillac EV concept sure looks neat. It's all-electric, too, which is even neater. Unfortunately, it's a concept car, and when it comes to concept cars with Cadillac badges on them, it's best not to get too excited. For instance, you might recall this exquisite piece of automotive art. It was called the Elmiraj. You might recall the production version became the bold face of a new Cadillac and inspired a renaissance for the brand. Jay-Z drives one. Oh wait, no he doesn't. It was never made, nor was anything like it made. This is the Cadillac Escala. It has certainly inspired design cues on production Cadillacs, most notably the just-revealed XT6. However, besides those cues, it's a pretty anonymous large crossover. Hardly anything as stunning as the Escala. Now, perhaps the CT5 will be a dead-ringer, but we wouldn't get our hopes up. Then there's this, the Ciel. Not to be confused with an Acura CL, it was 100 feet long, a convertible and purple. This was also not made. OK, we can see why. And finally, this is the Cadillac Sixteen. As the name suggests, it had 16 cylinders. That's a lot. The most you can get in a Cadillac today is half that many. Now, to be fair, most manufacturers produce concept cars that have zero chance of production. They are meant to serve as inspiration for future designs, showcase future technologies or just draw attention to the brand. The problem with the Cadillac concepts is that they're not that fanciful. Those aren't pod-like Jetsons cars up there. They aren't this nonsense. They look like modern interpretations of the exact sort of grandiose cars Cadillac used to make. The very cars that made Cadillac the "Cadillac of the World." You know, like this. I'm not talking about literal tail fins and pink paint, but that's a CADILLAC. It's confident. It's its own thing. It doesn't need to beat BMW around the Nurburgring to prove something to someone somewhere. The Elmiraj was also a CADILLAC. The XT6 literally wears a Cadillac badge, but it could be anything. By contrast, Lincoln is doing a much better job of tapping into the spirit of its grand past with the Navigator, Aviator and suicide-doored Continental. Nowhere is that better seen than in the cabins of the XT6 and Aviator. One is swank. The other is not. But back to where we started: that EV concept. You'll note that it doesn't actually have a name.

2020 Cadillac XT6 revealed as Caddy's first big crossover

The 2020 Cadillac XT6 rounds out Cadillac's crossover lineup with a range-topper. It also presents an option for people who wanted a three-row Cadillac but didn't want something as large and truck-like as an Escalade. This is partly achieved through using a naturally aspirated 3.6-liter V6 powering either the front or all four wheels. A nine-speed automatic transmission sends the V6's 310 horsepower and 271 pound-feet of torque to the ground. The XT6 is split between two trim levels that appear to be marketed as different rather than one being better. The first is redundantly called Premium Luxury. A chrome grille and trim, red taillights and unique 20-inch wheels distinguish it as such from the outside, while wood trim covers the inside. The second is Sport, and black trim replaces the chrome, red taillights are swapped for clear, and carbon fiber supplants the wood inside. It has different 20-inch wheels as well as optional 21-inch pieces. The Sport gets mechanical tweaks, too, including continuously adjustable shocks and a standard all-wheel-drive system with yaw control. No matter the trim, all XT6's get an interior that builds upon the XT4 with more physical buttons and a control knob for the infotainment for scrolling through menus and lists. Safety and convenience features abound, including standard automatic emergency braking, blind-spot warning and lane-keep assist. Optional features include night vision, parking assist with braking support, a heads-up display and a camera screen mirror. Adaptive cruise control is also available, but it's not Super Cruise, our Tech of the Year award winner. Cadillac will start taking orders for the Tennessee-built crossover this spring. The final release date hasn't been announced yet, though. That information, along with pricing, should come closer to when the crossover begins production. Related Video:
