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 gets a plug in Shanghai, will come to US

Don't call it the third coming of the Chevy Volt. The unsurprising debut of the Cadillac CT6 PHEV in Shanghai today has a powertrain that sounds an awful lot like the one that can be found in the Volt and the Cadillac ELR. The plug-in CT6 – identical to the CT6 that debuted in New York earlier this month – has an 18.4-kWh lithium-ion battery (just like the 2016 Volt) and offers an all-electric range of around 37 miles. It also copies the "Regen on Demand" feature from the new Volt and the battery cells "use the latest generation cell chemistry found in other GM plug-in vehicles." But Cadillac President Johan de Nysschen doesn't see the two powertrains as similar in at least one important way. General Motors calls the Volt and the ELR "extended range electric vehicles" (EREV) but in a statement, de Nysschen says that the plug-in hybrid CT6 is, "an ideal platform for Cadillac to offer its first plug-in hybrid." That GM is using the PHEV terminology rather than EREV is going to be important to some, even if the practical difference is only semantic. And yes, we all understand the irony of de Nysschen – the same guy who has a history of speaking ill of plug-in cars – hyping them now. Back when he worked for Audi, he said the original Volt was too expensive for what it offered and was thus, a car for "idiots." Speaking in Shanghai today, de Nysschen said the new CT6 PHEV was, "an EV without any of the disadvantages or range constraints," according to Automotive News. If the batteries are similar to GM's other EREV/PHEV cars, the CT6 powertrain is at least different. The ELR uses a 1.4-liter engine, while the new Volt has a 1.5-liter four-cylinder mill. The CT6, on the other hand, has a 2.0-liter turbo four-cylinder engine with direct injection. There is also an "all-new rear wheel electric variable transmission (EVT) with exclusively designed motors," that will give the CT6 PHEV, "smooth, spirited acceleration." The EVT is a two-motor-unit that uses three planetary gears. Maximum overall system output is 335 horsepower and 432 pound-feet of torque. Perhaps most interesting for American audiences is the fact that GM's press release, available below, makes multiple references to US-market sales of the PHEV. Official details on the EV range and fuel economy will be made available closer to the car's US launch.

Cadillac's Euro reboot may have implications for US models, sales

Firmly on the comeback trail in the US, Cadillac is still trying to get out of the starting blocks in Europe. At the Geneva Motor Show in March, Cadillac' senior execs revealed plans to grow the brand's presence in a luxury market dominated by the big three German marques, Audi, BMW and Mercedes-Benz.
GM President Dan Ammann says he sees "enormous" potential for Cadillac globally.
Over the past 20 years, the General Motors premium nameplate has tried and failed multiple times to break into the European market. This time around, Cadillac recognizes that progress will be modest at best, and depends on specific changes to models, some of which may impact the brand's US lineup. Planned new sales tactics in Europe may also impact the way Cadillac does business on this side of the pond.
