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.

GM offering factory-backed extended warranty for Chevys, GMCs, Buicks and Cadillacs

Cars are generally more reliable than ever before. When things do go wrong, every automaker offers some form of factory warranty (in most cases at least three years and 36,000 miles, though many extend even longer), providing peace of mind to new-car buyers that many faults will be fixed at no charge to the customer. Starting today, GM is offering a new optional plan that will extend the factory warranty on all new Chevy, GMC, Buick and Cadillac products. In the past, extended warranties have been offered as dealer add-ons, with all profits from these sales going to the dealership. GM's new program can be viewed as another nail in the the looming dealership-model coffin. According to Automotive News, some dealers aren't happy to see GM cut into their business like this, saying that it helps GM far more than it does dealers. GM says the new program will help keep customers in the GM family. Customers are also more likely to visit a GM service center rather than going to an independent repair shop. Currently, new Chevy and GMC vehicles come with three-year/36,000-mile warranties. Buicks and Cadillacs are covered for 4 years or 50,000 miles. The new program extends Chevy and GMC warranties to five years or 60,000 miles. Buick and Cadillac warranties extend to six years or 70,000 miles. GM, citing IHS Markit, says most owners keep new cars for about 6.8 years, so these warranties will cover most of the length of their ownership. The extended warranty will add between $1,000 and $2,000 to the price of a vehicle, and the additional cost can be rolled into the vehicle's purchase or lease price. Unlike many dealer extensions, the factory program covers the vehicle no matter who owns it. That should help increase the car's resale value if it's sold within the covered timeframe. GM says there's no deductible and no need to file a claim form when getting warranty repairs. Additionally, dealerships can continue to sell their own extended warranties or service contracts.

2020 Cadillac XT6 revealed as Caddy's first big crossover

The 2020 Cadillac XT6 rounds out Cadillac's crossover lineup with a range-topper. It also presents an option for people who wanted a three-row Cadillac but didn't want something as large and truck-like as an Escalade. This is partly achieved through using a naturally aspirated 3.6-liter V6 powering either the front or all four wheels. A nine-speed automatic transmission sends the V6's 310 horsepower and 271 pound-feet of torque to the ground. The XT6 is split between two trim levels that appear to be marketed as different rather than one being better. The first is redundantly called Premium Luxury. A chrome grille and trim, red taillights and unique 20-inch wheels distinguish it as such from the outside, while wood trim covers the inside. The second is Sport, and black trim replaces the chrome, red taillights are swapped for clear, and carbon fiber supplants the wood inside. It has different 20-inch wheels as well as optional 21-inch pieces. The Sport gets mechanical tweaks, too, including continuously adjustable shocks and a standard all-wheel-drive system with yaw control. No matter the trim, all XT6's get an interior that builds upon the XT4 with more physical buttons and a control knob for the infotainment for scrolling through menus and lists. Safety and convenience features abound, including standard automatic emergency braking, blind-spot warning and lane-keep assist. Optional features include night vision, parking assist with braking support, a heads-up display and a camera screen mirror. Adaptive cruise control is also available, but it's not Super Cruise, our Tech of the Year award winner. Cadillac will start taking orders for the Tennessee-built crossover this spring. The final release date hasn't been announced yet, though. That information, along with pricing, should come closer to when the crossover begins production. Related Video:
