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 420-hp twin-turbo V6 for 2014 CTS [w/videos]

The 2014 CTS will break cover next week at the New York Auto Show, but Cadillac has released a few details of what we can expect to find under the car's hood. As we saw in some spy shots back in January, the biggest news for the midsize Caddy will be a twin-turbocharged V6 producing a whopping 420 horsepower and 430 pound-feet of torque.
This LF3 engine will be paired to a new eight-speed automatic transmission, which will help balance performance and fuel economy. We still don't know how much the 2014 CTS has grown in terms of size and weight, but General Motors says that new sedan will return 17 miles per gallon in the city and 25 mpg highway with the new engine to go with a 0-60 mile per hour time of 4.6 seconds - that means the new CTS will have the fuel economy close to the current base model sedan and acceleration not too far from the current CTS-V. General Motors also confirmed that this twin-turbo V6 will be available in the 2014 XTS this fall.
The next-generation CTS will carry over the 3.6-liter V6 from the current car (likely as a base engine) and also add the 2.0-liter turbo four-cylinder from the ATS. Check out all the details on this new engine and watch a few videos (including GM's nifty tilt rig) by scrolling below.

Cadillac Rear Camera Mirror | 2017 Autoblog Technology of the Year Finalist

We give Cadillac a lot of credit for being the first to make good on the promise to replace mirrors with cameras and displays. That was good enough to earn the Cadillac Rear Camera Mirror a place on our 2017 Technology of the Year awards shortlist for new features. The idea behind this system is relatively simple; what perhaps took more doing was getting the regulations in place to allow a video feed to replace the government-mandated mirror. The hardware and that rules compliance starts with what looks like a normal rearview mirror – because it defaults to being a mirror until you switch on the display or in the event the system somehow fails. Flip the little toggle at the bottom of the mirror – the one normally used to switch from day to night mode – and the reflection is replaced by a very crisp feed from a camera at the back of the vehicle. This live stream gives you a wide-angle view of what's behind, without obstruction from back-seat passengers, headrests, or any bodywork. The camera is even shielded from weather and has a coating to shed water. What you see doesn't exactly look like a normal reflection, but the quality is good enough and you see more than you would normally with something aimed through today's small rear windows. But because it isn't actually a reflection, you have to make some adjustments. When your eyes are focused down the road, glancing at a mirror gives you a view the same distance away but in the rear. With the rear camera mirror, a glance back requires your eyes to first refocus on the display, which takes a moment. And unlike a normal mirror, which you look through at an angle, this display is angled toward the driver but projecting an image that looks straight back – no matter how you move it, the image doesn't change like a mirror's would. And because it's an image and not a reflection, you can't choose what's in focus and lose your sense of depth perception. It's not clear whether objects in mirror are closer or farther than they appear. And there are other limitations. For instance, while the display balances bright lights and dark surroundings well at night, it is tricked by LED headlights, which flicker at a rate faster than the camera shoots. The result is a distracting strobe effect like you get when you point a smartphone camera at any LED light source. For those with migraine sensitivity, this kind of fast flashing can cause real problems.
