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 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.

Cadillac upgrades ATS sedan to match new coupe

The big news when it comes to the Cadillac ATS for 2015 is surely the addition of the new coupe model, but that doesn't mean that Cadillac has forgotten about the sedan as well. In fact GM's luxury brand has rolled out a few choice enhancements for the four-door to bring it more in line with the new coupe.
Among those changes that we spotted a couple of weeks ago is a new front fascia that incorporates the brand's new wreath-less emblem, and a sleeker front bumper. The interior has been upgraded as well with new trim options as well as some new tech including Siri Eyes Free functionality, dictated text messaging and optional inductive smartphone charging.
Though the ATS Coupe does away with the base engine, sedan buyers can still opt for the 2.0-liter four with 202 horsepower and 191 pound-feet of torque. The 3.6-liter V6 carries over unchanged at 321 hp and 275 lb-ft, but the 2.0-liter turbo four gets the upgraded torque rating of 295 lb-ft (the highest in the range) to go with its 272 hp. Some new color choices are also among the upgrades you can read more about in the press release below.
