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 confirms 'Blackwing' name, manual gearboxes for pumped-up CT4-V, CT5-V

Cadillac officially confirmed Tuesday that the high-output variants of its new CT4-V and CT5-V sedans will be dubbed "Blackwing," sharing a nameplate with GM's stillborn twin-turbocharged V8. As an added bonus, company representatives said for certain that both of Cadillac's new super-sedans will be offered with a manual transmission, confirming long-standing rumors to that effect.  "The Blackwing name has come to represent the very best of Cadillac performance engineering, craftsmanship and technology," said Cadillac chief engineer Brandon Vivian. "The new CT4-V Blackwing and CT5-V Blackwing build on the brand’s respected legacy of ultimate-performance driving experiences and elevate them even further." Cadillac says the two Blackwing sedans, which are successors to the critically acclaimed ATS-V and CTS-V, will represent "the apex of Cadillac performance and driver engagement." The company also remained mum on just what to expect in terms of capability, teasing only the fact that both the CT4-V and CT5-V Blackwing posted quicker lap times in testing at Virginia International Raceway earlier this year than their predecessors did.   Rumors have pointed to the CT5-V Blackwing making use of the company's supercharged 6.2-liter V8, which also powered its predecessor. The 6.2 shares its architecture with the company's flagship, naturally aspirated V8, making it an economical choice for powering performance cars. The smaller CT4-V is likely to be motivated by a turbocharged 6-cylinder. They will also be available in limited numbers, though Cadillac's announcement did not elaborate on just how many (or few, as the case may be) will eventually be built, or how many model years to expect. The CT6-V, which carries the 4.2-liter V8 that shares the "Blackwing" name, saw only limited production before being axed.  The V8 itself may find a new home down the road, but for the time being, it's toast.  Cadillac assured us that more information on the new CT4-V and CT5-V Blackwing will be come along soon enough. For now, at least we know what they're going to be called.  Related Video:    

Cadillac back on track with 600-hp ATS-V.R racer in FIA GT3 spec [w/video]

There was already a rumor brewing that Cadillac might eschew the CTS as its racecar next season in favor of the ATS Coupe. It turns out that is absolutely the case, and now we know just what this 600-horsepower, future racer looks like. The coupe might not be limited to competing in just the US, though, because it's built to FIA GT3-specifications, meaning that this Caddy is also eligible to race in over 30 series worldwide against the likes of Bentley, McLaren, Audi and other premium brands.
The heart of this massively winged Cadillac is an engine dubbed the LF4.R. It's based around the unit in the production ATS-V and CTS Vsport but with larger turbos, bigger intercoolers, side exhausts and other tricks. Cadillac claims it makes a monstrous 600 hp and 520 pound-feet of torque in unrestricted form.
As the photo above shows, the ATS-V.R also wears an aggressive aero kit with a carbon fiber front splitter, and a wing at the back that could probably double as a picnic table in a pinch. The dry weight of the whole package is quoted at about 2,900 pounds, which is around 700 pounds less than the street version.
