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 Cadillac ATS Coupe First Drive

Save for a few years of its century-plus existence, Cadillac has offered its unique brand of American elegance in two-door, fixed-roof bodystyles. Most of these cars were big, floaty barges, of course, though its most recent offering was the wedge-shaped CTS Coupe. But whereas the CTS Coupe was a statement car – angular and severe, with somewhat limited appeal except to design snobs and provocateurs – the ATS Coupe represents a return to form for Cadillac, with a proper three-box (engine-cabin-trunk) body and a slightly lower price point that should broaden its appeal among a larger swath of the market. Generally speaking, the 2015 ATS Coupe is a two-door version of the sporty ATS Sedan, though, surprisingly, the only common exterior components are the hood, headlamps, and sundry trim pieces on the front fascia (which features a slightly larger grille, a wider lower air intake, and the redesigned, laurel-less Cadillac crest). Even the mirrors are different. The body stretches 0.8 inches in length and 1.4 inches in width, the roof is 1.1 inches lower and the rear windscreen slopes at a flatter, sleeker angle. Interestingly, the windowsills are actually quite a bit lower, further slimming the car. Thanks to its 0.8-inch wider front and rear wheel tracks as well as more tumblehome in the C-pillar area, the coupe sits lower and looks more planted than the ATS sedan, particularly from the rear three-quarter view. Filling the wheel wells is a family of slick 18x8-inch wheels, with 18x9-inchers coming on the rear axle of performance models. Even if all those changes haven't resulted in a wholly new look the way the CTS Coupe departs from its sedan progeny, the ATS two-door is a truly beautiful car that looks considerably better on the road than on a show stand. And for that, Cadillac deserves mighty praise. The ATS two-door is a truly beautiful car that looks considerably better on the road than on a show stand. It is a proper coupe, of course, and as such is saddled with the expected limitations that accompany modern two-door packaging, notably rear seat access and limited rear headroom. Since the floorpan is common to both bodystyles, rear legroom is the same as the sedan's, though headroom shrinks a considerable 1.8 inches, making it hard for even average-sized adults to sit back there without their heads touching the window glass.

Hennessy wastes no time in supercharging the 2015 Cadillac Escalade

The ink is still drying on the all-new 2015 Cadillac Escalade sales brochures, but that hasn't stopped Texas-based Hennessey Performance (HPE) from leaping out of the gate with its own high-performance variant. In stock form, the big fourth-generation Cadillac flagship arrives with a new small block naturally aspirated 6.2-liter Ecotec3 V8 delivering 420 horsepower and 460 pound-feet of torque. Fresh out of the showroom, the 5,900-pound SUV will sprint to 60 mph in 5.9 seconds.
While that is plenty fast for some owners, others don't want to be shamed by a 550 horsepower Mercedes-Benz GL63 AMG or a 510 horsepower Land Rover Range Rover Sport - both will leave the stock Escalade at a stoplight.
The team at HPE has come to the rescue with its HPE550 supercharger upgrade, which includes a belt-driven supercharger, air-to-water intercooler, recalibrated engine management software and a three-year/36,000 mile powertrain warranty. With 6 psi of boost, the direct-injected 6.2-liter is tuned to deliver an impressive 557 horsepower and 542 pound-feet of torque - gains of 32 percent and 18 percent, respectively, over stock. Although HPE isn't releasing performance figures as of yet, our math says that should be enough power to put the two Europeans in the Cadillac's rearview mirror. The company also offers a set of 20-inch lightweight H10 forged monoblock wheels, to further improve performance.
