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.

Jeff Gordon will come out of retirement to race new Cadillac endurance racecar

Jeff Gordon is not a man who takes well to retirement, apparently. That's not a surprise at all, given that we've been talking about his return to racing since almost the minute he retired in the first place. This year, he's taken the wheel for Dale Earnhardt, Jr., who is recovering from a concussion, several times already. So we shouldn't be too surprised to find out he's officially coming out of retirement – the twist is that it won't be in a stock car. Gordon has signed onto Wayne Taylor Racing, Motorsport.com reports, and he'll join Ricky and Jordan Taylor as well as Max Angelelli. Their ride will be the newly-revealed Cadillac DPi-V.R racer, a Dallara-chassis car powered by a 6.2-liter pushrod V8 loosely related, Cadillac claims, to the engine in the current CTS-V. You can read all about the DPi-V.R right over here. Remember, Gordon has a total of 93 NASCAR wins to his name, as well as four titles. He knows his way around Daytona pretty well, too, having won the 500 three times. He's also dabbled in endurance racing once before, in the 2007 24 Hours of Daytona with Taylor, Angelelli and Jan Magnussen in a WTR Riley-Pontiac car. They ended up on the podium, so you can say Gordon's inaugural and only outing in endurance racing so far was a success. It's been a decade, so we'll see if he's rusty, although knowing about how competitive champions are, we think he'll blow out the cobwebs and get right down to work. You can read Gordon's statement over at his personal site. Related Video:

Cadillac will kill the plug-in ELR

Johan de Nysschen, president of General Motors' Cadillac division, says Caddy's ELR extended-range plug-in won't have any future generations, Automotive News (subs. req.) says. The publication previously reported that the car would be around for another couple of years, but even that's questionable, and the model could be yanked even sooner. Cadillac spokesman David Caldwell confirmed that there won't be a second-generation ELR. "Subsequent generations of the car will not be developed," he wrote in an e-mail to Autoblog. "It's available currently as a 2016 model, and there's no change to that status." The model debuted in late 2013 and used a version of the powertrain in the Chevrolet Volt. The main problem, of course, was that the car had a $76,000 price tag that proved too much for most automobile buyers to stomach. Last year, GM sold 1,024 ELRs, down 22 percent from 2014's totals. By comparison, the Chevy Volt moved more than 15,000 units, and that itself was still down 18 percent from year-earlier figures. The merciful end to the ELR shouldn't be much of a surprise, as Cadillac Chief Marketing Officer Uwe Ellinghaus went on the record in December of essentially calling the model a dud. It's a far cry from the excitement, though, that the concept model of what was then called the Converj was unveiled to the public at the Detroit Auto Show in 2009. For those feeling misty-eyed or nostalgic, though, check here for Autoblog's First Drive impressions of the extended-range plug-in.
