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 CT6 will get high-res streaming video rearview mirror

Cadillac is preparing a big upgrade to the humble rearview mirror, adding a streaming video function that it claims will improve a driver's field of vision by 300 percent. The new system will debut on the 2016 CT6 flagship. The streaming system, which eliminates the visual obstructions caused by passengers, headrests and the rear pillars, relies on a 1280-by-240-pixel TFT display and a high-definition camera to reduce glare and improve visibility in low-light conditions. That camera even addresses one of the big annoyances of today's camera systems, by adding a hydrophobic coating to keep the camera lens clear. The system can easily be switched off at the press of a button, at which point the driver has a simple electrochromatic mirror at his disposal. "The closest comparison to this kind of rear vision would be driving a convertible with the top down," Travis Hester, the CT6's executive chief engineer said in a statement. "The streaming video is a significant enhancement for the luxury customer interested in purposeful technology." Scroll down for the press release from Cadillac. Cadillac Adds Streaming Video to Enhance Driver Vision and Safety Display eliminates visual obstructions, increases rearward vision by 300 percent 2014-12-18 DETROIT – Cadillac late next year will add high-resolution streaming video to the function of a traditional rearview mirror, removing obstructions of passengers, headrests and the vehicle's roof and rear pillars. The streaming video mirror improves field of vision by an estimated 300 percent, or roughly four times greater than a standard rearview mirror. "The closest comparison to this kind of rear vision would be driving a convertible with the top down," said Travis Hester, Cadillac CT6 executive chief engineer. "In addition to the increased field of view, the technology eliminates any rear seat, rear pillar or passenger obstructions, allowing the driver an unimpeded view of the lanes behind and traditional blind-spots," Hester said. Thanks to a high dynamic range, the camera's video feed reduces glare and allows a crisper image in low-light situations, versus a traditional glass electrochromatic, or auto-dimming, rearview mirror. The in-mirror display is an industry-leading 1280 by 240-pixel TFT-LCD display with 171 pixels per inch, combined with a HD camera designed specifically to enhance rear view lane width and maximize low-light situations.

New V6 engines are only the start at Cadillac

Cadillac debuted its new family of V6 engines Friday, but that's not all General Motors' luxury brand has in store for the coming years. The six-cylinder powerplants will certainly help Cadillac in the near term, but they're just two of the many parts of the company's future strategy. GM has invested $12 billion in Cadillac to help the brand grow over the next five years, and the company will launch eight new products between now and 2020. That all starts with the launch of the CT6 flagship later this year – a fullsize luxury sedan we'll see for the first time in New York on March 31. The CT6 will introduce several new features and technologies to the Cadillac range, and with its launch also begins the slow restructuring of Cadillac's model-naming system. The new nomenclature means CT and XT badges for cars and utilities, respectively. Cadillac says that of the eight new vehicles it plans to launch by 2020, five of them will be first-time offerings in market segments where the brand currently does not play. But it's not just about new products – new powertrains are an important part of the Cadillac story, too. After the new V6 engines – a naturally aspirated 3.6-liter and a twin-turbocharged 3.0-liter engine – launch later this year in the 2016 ATS, CTS and CT6, the company says it has a strategy for V8 power – possibly a twin-turbo application – as well as future electrification. Cadillac also says it's working on adding four- and six-cylinder diesel powertrains, though it's unclear which vehicles will make use of those engines. This new six-cylinder engine family is indeed important, with Cadillac's chief engineer, David Leone, calling it the "most advanced V6 in the industry." With 335 horsepower, the 3.6-liter engine is the highest output, naturally aspirated V6 powerplant Cadillac has done – and that's SAE-certified, and on regular fuel. Beyond that, the 3.0-liter mill (pictured at right) marks the first application of GM's active fuel management system on a twin-turbocharged engine. This means that when full power isn't necessary, the TTV6 can run as a 2.0-liter V4 in order to save fuel. New transmissions are also part of the V6 engine story. GM's all-new eight-speed Hydra-Matic 8L45 gearbox will be paired to the 3.6-liter V6, and the 3.0-liter TTV6 will use the company's existing 8L90 transmission that is already found in the Chevrolet Silverado and GMC Sierra pickups (with the 6.2-liter engine).
