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.

2016 Cadillac CT6 has arrived

We have known for a while that the 2015 New York Auto Show would mark the debut of Cadillac's latest flagship model. But after months of waiting as Caddy slowly revealed details, the 2016 Cadillac CT6 has finally arrived. The sedan is a technological tour de force for the brand and inaugurates a long list of new technologies. The CT6 will begin production at the Detroit-Hamtramck Assembly plant in late 2015 and will go on sale with three engine options. Caddy won't release final figures yet, but based on preliminary numbers, we know the base 2.0-liter turbocharged four-cylinder will make 265 horsepower. Stepping up to the newly revised 3.6-liter V6 will net buyers an estimated 335 hp, and finally there will be the 3.0-liter twin-turbo V6 with an output of around 400 hp. All of these engines will be mated to eight-speed automatic transmissions, and six-cylinder models will get standard all-wheel drive that will be able to constantly vary the power sent to the front wheels. Carrying those powertrains is the new, aluminum-intensive Omega architecture. In addition to the lightweight metal making up the platform, the entire exterior also uses it to provide an estimated curb weight of less than 3,700 pounds. The decision to shed mass makes the CT6 a featherweight in its class – for comparison, the lightest, six-cylinder Audi A8 weighs 4,365 pounds. The sedan rides on a 122.4-inch wheelbase and is 204 inches long. That makes the Cadillac about 1.3 inches shorter than the smallest BMW 7 Series, but the Caddy is projected to tip the scales at less than both the big Bimmer and even the 5 Series, too. Cadillac wants the CT6 to be a luxury sedan that drivers can enjoy. In addition to the low weight, there's an available Active Chassis System throughout the range with rear-wheel steering and Magnetic Ride Control. When combined with the all-wheel-drive system, it means every corner of the car is both driving and steering the vehicle. Inside, the CT6 offers a ton of tech and luxury. Drivers are held in massaging, leather seats, and rear passengers also get adjustable chairs that are heated and cooled. Quad-zone climate controls keep everyone comfortable. Plus, in addition to the 34-speaker Bose audio system and streaming rearview mirror, there are features like a 10.2-inch CUE infotainment system with a capacitive touchscreen and console-mounted touchpad. The display also shows a 360-degree view outside and can even record video when the security system is activated.

GM promises to add 20 EVs and fuel-cell cars to lineup, paid for by SUVs

DETROIT — General Motors outlined plans on Monday to add 20 new battery electric and fuel-cell vehicles to its global product lineup by 2023, financed by robust profits from sales of gasoline-fueled trucks and sport utility vehicles in the United States and China. "General Motors believes in an all-electric future," GM global product development chief Mark Reuss said on Monday during a briefing at the company's suburban Detroit technical center. Future generations of GM electric vehicles "will be profitable," Reuss said, but added it was not clear when GM could make all its new vehicle offerings zero-emission electric cars. Regulators in China and some European countries have floated proposals to ban internal combustion engines by 2030 or 2040. "We will continue to make sure our internal combustion engines will get more and more efficient," Reuss said. GM shares were up more than 4 percent in midday New York trading on positive comments from Rod Lache, auto analyst at Deutsche Bank. Automakers, including electric vehicle market leader Tesla, lose money on electric cars because battery costs are still higher than comparable internal combustion engines. The company offered sneak peeks of three EV prototypes: a Buick SUV, a sporty Cadillac wagon and a futuristic pod car wearing a Bolt badge. GM funds its forays into new technology using a river of cash generated by old-technology vehicles popular with its core customer base in the United States heartland. In comparison, Tesla has burned through an estimated $10 billion in cash and has yet to show a full year profit. GM earned more than 90 percent of its $12.5 billion in pretax profits last year in North America, amid robust demand for its lineup of large sport utility vehicles and pickup trucks. The company's profitable operations in China rely on consumer demand for an expanding lineup of gasoline powered SUVs. GM has previously announced plans to make some of its future electric vehicles capable of driving themselves in robot taxi fleets. The company offered sneak peeks of three electric vehicle prototypes: a Buick brand sport utility vehicle, a sporty Cadillac wagon and a futuristic pod car wearing a Bolt badge. GM collaborated with Korean battery maker LG Chem to build the Bolt battery system. Company officials did not say what companies would supply batteries for the larger fleet of vehicles promised by 2023. Fuel-cell vehicles will also play a role in GM's future, the company said.
