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 ATS was almost front-wheel drive

"We were going to do a front-wheel drive Cadillac compact off of Delta because it was going to be less expensive," Doug Parks, General Motors' vice president of global product programs, told the Automotive News during the Detroit Auto Show in January of this year. That sentence, referring to early ATS discussions more than five years ago - a period when the automaker, and the industry, was struggling - reveals that Cadillac's highly acclaimed rear-wheel drive compact sedan almost never happened.
Parks revealed that that automaker actually built a 2.0-liter test mule, on GM's Delta platform (shared with the Chevrolet Cruze and Buick Verano) and tested it in Europe. While the prototype was "pretty darn good," according to Parks, the team realized that in order to compete against Mercedes-Benz and BMW it would have to invest in a new rear-wheel drive platform.
The resulting all-new Alpha platform would eventually underpin the Cadillac ATS, and many would argue that its balanced rear-wheel drive chassis is its single most important attribute. Thankfully, the Alpha's goodness won't stop with the ATS. The upcoming 2014 Cadillac CTS and the future Camaro will also share its architecture, meaning the Cimarron will remain a distant memory.

GM recalls 2014 Cadillac CTS recall

No, that headline isn't a typo - General Motors has reportedly issued a recall for one of its own recalls. The recall of a recall affects the recall of the 2014 Cadillac CTS, which wasn't supposed to be recalled. Except that the 2014 CTS was supposed to be recalled. Oh no, now we've gone cross-eyed.
Allow us to explain. The redesigned, third-generation CTS Sedan does not feature a faulty ignition switch, while the 2014 CTS Coupe and Wagon, which are based on the second-gen car, do. And as it turns out, there are only 264 of those vehicles included in last week's 8.2-million-unit, ignition-switch recall. Model year 2003 to 2013 CTS Sedans, Coupes and Wagons are still covered.
It's not entirely clear how this, frankly, colossal mistake was made, although we're betting GM is rapidly trying to get to the bottom of this embarrassing issue. Regardless, let's just take what solace we can in there being one less vehicle that GM has recalled this year.
