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.

Roll pins in recalled 2014-2015 Cadillac CTS V-Sports could crack

General Motors has issued a recall for select 2014-2015 Cadillac CTS V-Sport sedans due to roll pins in the rear differential that could crack. The recall only affects 2,866 vehicles, but it is expected that 100% of those vehicles have the defective parts. According to NHTSA Campaign No. 20V038000, 2014-2015 CTS V-Sports built between July 1, 2013 and May 15, 2015 have roll pins in the rear-axle differential that could "fatigue" and "fracture." If these pins were to break while the vehicle is in motion, it could cause the rear to lock up, which might create a potentially dangerous driving situation. In September 2019, a GM engineer noticed a forum discussion about the problem with the V-Sports, which can be easily identified by their twin-turbo 3.6-liter V6 engines. Because he had dealt with similar issues with his own personal vehicle, he submitted a report, and an investigation was opened the next month. To make good with its customers, GM has promised to replace the rear differentials on all affected vehicles. The recall report says the roll pins in the replacement parts will have "increased strength" and a double-shear design rather than the original single-shear design.  GM plans to send customers recall identification notices starting March 9, 2020. 

Cadillac to ditch China-only LWB models for global 'right size'

We often think of Buick being General Motors' poster child in China, but would it surprise you to hear that Cadillac is just doing a bang-up job in the People's Republic? It's true, the Standard of the World is on fire, and it's doing so with a surprising group of buyers that are going to push through globe-spanning changes for the brand. Cadillac's average buyer age in the People's Republic of China is just 34. Yes, younger buyers dominate the Chinese market, but according to Reuters, Cadillac's young buyers want to drive and they don't want the typical businessman's German-badged sedan. Cadillac understands this, and is setting about to exploit it with a shift in its Chinese strategy. According to President Johan de Nysschen, the company will begin moving away from the China-only, long-wheelbase models, like the ATS-L. Instead, it will push for a global "right size" design, along with some stylistic changes. "You will see a softening of some of the hard edges, and more three-dimension styling on the side of the car," de Nysschen told Reuters, while noting that the cars will still be "instantly recognizable as Cadillac." Even without these changes, though, Cadillac has bucked the trend in China. At 17 percent, the company's sales exceeded the PRC's overall market growth of 7.3 percent by a significant margin. In fact, Cadillac's 2015 gains outpaced the overall market growth in China over the past three years, as the brand jumped to nearly 80,000 units. And the company is hoping to push that even higher, Reuters reports, with President Johan de Nysschen targeting a 25-percent increase in 2016. Related Video:
