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 SRX and Saab 9-4X recalled for suspension defect

General Motors has recalled 380,498 vehicles due to rear suspension toe link adjusters that may not have been tightened properly, which could result in a loose toe link. The vehicles affected by the recall are Cadillac SRX crossovers built between 2010 and 2016, and Saab 9-4X crossovers built in 2011 and 2012. A loose toe link could cause instability while driving, especially at highway speeds. This recall follows up an investigation by the National Highway Traffic Safety Administration after it received complaints from SRX drivers of uncontrolled swaying while driving. According to the agency, two incidents led to a crash. It's possible that improper procedures for tightening a toe link nut during four-wheel alignments may have resulted in corrosion and thread wear on the adjustable portion of the link. Owners of affected vehicles are advised to park their crossovers if they experience certain Malfunction Indicator Lamp warnings on the dashboard or if they feel unusual steering behavior while driving. According to the official NHTSA recall notice, dealers will replace the adjustable toe link with a non-adjustable one at no charge. Letters are expected to be mailed to owners of affected vehicles on August 9, 2021. Alternatively, owners can call Cadillac customer service at 1-800-458-8006 or Saab customer service at 1-800-955-9007 and reference recall number N212340980. This is the second time many of these vehicles have been recalled for problems with the rear toe links. Back in September of 2014, GM announced that it would recall 290,241 vehicles that included SRX and 9-4X models because a "nut in the rear suspension toe adjuster link may not be torqued to the proper specification." 

Cadillac Celestiq previewed as a flagship luxury electric car

Last year, our Autoblog Green editor, John Beltz Snyder, got a sneak peik of GM's upcoming electric car roll out. No photos were given, but he described them in great detail. Now we finally get our own peek at one of those cars, the Cadillac Celestiq flagship sedan. Sadly, we don't get a particularly clear look, since Cadillac is only teasing the car at this point, but it's better than nothing, and better than most teasers. We get a top-down shot that reveals the car will share some key cues with the Lyriq crossover EV. Most obvious is the rear with the boomerang taillights and fastback roof, which is a glass unit separated into four pieces. Each piece can be individually adjusted for transparency, and it appears they can be illuminated as well. The front also appears similar to the Lyriq with a geometric grille covered in a transparent panel. The grille looks significantly larger, though. It also features illumination like the crossover. We also get a look at the interior, which prominently features a full-width screen for instruments and infotainment. There appears to be a screen in the center console/stack that can control functions including the roof panel illumination. According to Snyder, the interior also has extensive wood and metal trim intermingling with nifty ambient lighting. Cadillac didn't say much about the mechanical aspects except the basics. It will use GM's Ultium battery technology that will be shared with other products such as the aforementioned Lyriq and the GMC Hummer EV. It will also feature four-wheel steering as well as all-wheel-drive, undoubtedly courtesy of dual motors, one front and one rear. Cadillac previously confirmed that the Celestiq is headed for production. We also suspect that some of the fancy features such as the screens and multi-panel glass roof could make it to production. This is because it's meant to be a halo product showing off the ultimate in luxury and technology from the brand, and it could have a price tag larger than $200,000. We're expecting Cadillac to fully reveal the Celestiq in a few months, but it could be a while before the production version hits the road. The Lyriq isn't going on sale until late next year, and we would bet the Celestiq wouldn't come ahead of it. Related Video:
