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.

2015 Chevy Silverado, GMC Sierra recalled for steering issues

DETROIT — General Motors Co is recalling more than 1 million pickup trucks and sport utility vehicles in the United States due to issues with a temporary loss of power steering, the National Highway Traffic Safety Administration said. The recall is for 2015 models. They are: the Chevy Silverado 1500, Suburban and Tahoe, GMC Sierra 1500, Yukon and Yukon XL and Cadillac Escalade. The problem may cause difficulty steering the vehicle, especially at low speeds, increasing the risk of a crash, the auto safety regulator said in a document dated Sept. 12. The document did not highlight any reports of accidents and injuries, because of the power steering issue. GM dealers will update the power steering module software, free of charge for owners of the affected vehicles. In 2014, the No.1 U.S. automaker had recalled nearly 800,000 pickup trucks worldwide because of the same problem. GM did not immediately respond to a request for comment.Related Video:

2020 Lincoln Corsair vs 2020 Cadillac XT4 | How they compare on paper

The 2020 Lincoln Corsair compact crossover was introduced this year to replace the aging MKC. Our first impressions are that it's a thoroughly competent luxury machine, but where it fits in the market is interesting. Given its size and price tag, the Corsair basically slots in-between compact segments, with vehicles like the Audi Q3 below and Audi Q5 above. It's a distinctive position to be in, but not a unique one, as there's another comparably sized and priced SUV -- and an American rival, no less. The Cadillac XT4 was launched just last year to be its company's smallest crossover, boasting compelling design and ample technology features.  So which is better? To give you some idea, let's take a look at each vehicle's horsepower, torque, fuel economy, space, pricing and some slightly more subjective aspects about their luxuriousness and feature sets. You'll find all the nitty gritty numbers below, followed by more detailed analysis. And if you'd like to compare other luxury crossovers, be sure to check out our comparison tool. Engines, drivetrains and driving impressions Both the Corsair and XT4 come standard with turbocharged 2.0-liter four-cylinder engines, but the Corsair's is more potent with 250 horsepower and 275 pound-feet compared with the 237 horsepower and 258 pound-feet of the Cadillac. And to seal the deal, the Corsair has an optional turbo 2.3-liter engine with 280 horsepower and 310 pound-feet of torque. That's not only vastly better than the Cadillac, but one of the most powerful outputs in the compact luxury SUV segment. Both vehicles have standard front-wheel drive with optional all-wheel drive on the base engines. The 2.3-liter Corsair has all-wheel drive standard. The Cadillac does boast an extra cog in its transmission over the Corsair's eight-speed automatic, but there's not necessarily an advantage or disadvantage to be gleaned from that. When it coes to fuel economy, the Cadillac is victorious with a 26 mpg combined rating for the front-drive model, with the front-drive 2.0-liter Corsair coming just behind with 25 mpg combined. It's a three-way tie for third with the all-wheel-drive XT4, all-wheel-drive 2.0-liter Corsair and 2.3-liter Corsair all returning 24 mpg combined. Of course, the all-wheel-drive Corsairs have a small advantage here in that it delivers more power and torque than the Cadillac with the same fuel economy.
