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 planning more Vsport models

There's a new intermediate class of luxury performance cars emerging. Audi has been doing it for years with its S-line bridging the gap, in many cases, between the standard fare and the full-on RS performance range. BMW's getting in on it with the M Sport line slotting in below the full M models. And now Cadillac is joining the fun with its Vsport offerings.
Models like the CTS Vsport and XTS Vsport are packing a new 3.6-liter twin-turbo V6 with 410 or more horsepower (along with bigger wheels and brakes) to slot in between the standard model and any impending V variant. Well, it appears Cadillac isn't about to stop there.
Speaking with The Detroit News, Cadillac product chief Hampden Tener revealed that, based on the response to the XTS Vsport, the brand is planning more Vsport models. He did not, however, indicate which would be the next to get the slightly sportier treatment. With the full ATS-V expected to pack a version of the same engine powering the aforementioned XTS and CTS Vsport models, an ATS Vsport would have to pack a smaller engine to fit in below. That only leaves the SRX crossover, Escalade SUV and the upcoming ELR hybrid. Food for thought.

Cadillac calling in 4,900 CTS-V models for brake issue

General Motors is recalling just over 4,900 first-generation Cadillac CTS-V sedans built between September 6, 2003 and June 11, 2007. The affected vehicles are largely registered in cold weather states where rock salt is used on roads. The salt could corrode the front brake hose's fitting in the brake calipers, which could lead to a brake fluid leak, the National Highway Traffic Safety Administration's bulletin reads. Needless to say, that would make slowing down the Corvette-powered Caddy a challenge. The affected vehicles were registered and/or sold in the following states: Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin, and the District of Columbia. GM is set to begin notifying owners of the affected vehicles, who will need to report to dealers to have both front brake hose assemblies replaced. Repairs are, naturally, free of charge. Scroll down for the official NHTSA bulletin. Report Receipt Date: APR 15, 2015 NHTSA Campaign Number: 15V225000 Component(s): SERVICE BRAKES, HYDRAULIC Potential Number of Units Affected: 4,907 Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2004-2007 Cadillac CTS-V vehicles manufactured between September 6, 2003, and June 11, 2007, currently registered, or originally sold, in Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin and the District of Columbia. In the affected vehicles, snow or water containing road salt or other contaminants may corrode the front brake hose fitting at the caliper. CONSEQUENCE: Corrosion may cause the brake system to leak which could lengthen the distance needed to stop the vehicle and increase the risk of a crash. REMEDY: GM will notify owners, and dealers will replace both front brake hose assemblies, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for this recall is 15149. Note: This recall is an expansion of recall 10V-105. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
