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.

2021 Cadillac Escalade makes its grand debut among the stars during Oscars week

The 2021 Cadillac Escalade has arrived in high style in Los Angeles during Oscars week. With no January Detroit Auto Show, there’s no better place for the next generation of CadillacÂ’s iconic luxury SUV to be revealed than star-studded L.A. We got to spend some time in and around the Escalade a couple weeks ago, and now we can finally tell you all about it. As expected, the 2021 Escalade is following in the footsteps of all the other full-size GM SUVs by going with an independent rear suspension setup. Just like the Tahoe and Yukon, Cadillac is also making the next-gen magnetic shocks and new air suspension optional equipment. Engineers told us that thereÂ’s hardly any difference underneath the Escalade versus its platform stablemates, and our early impressions of the ride suggest thatÂ’s perfectly fine. Powering the new Escalade is GMÂ’s trusty 6.2-liter V8 or the 3.0-liter turbo-diesel inline-six — both are paired with a 10-speed automatic transmission.   Related: 2021 Cadillac Escalade vs. 2020 Lincoln Navigator | How they compare on paper 2021 Cadillac Escalade ESV will debut at the New York Auto Show   WeÂ’re not surprised to see the oil-burner being offered as an option with the Escalade after itÂ’s been tucked under the hood of the Tahoe and Yukon, but it is a significant addition to the Escalade lineup. GM has never fit a diesel engine to an Escalade before, but engineers tell us that this motor is refined enough for an Escalade buyer. We were surprised by its smoothness in the Silverado, and weÂ’ll wager itÂ’s even more discrete in the luxury SUV. The lovely 4.2-liter twin-turbo V8 Blackwing engine was never mentioned in CadillacÂ’s presentation to us. We asked, but thereÂ’s no news to be had on the Blackwing front, as Cadillac shrugged us off. Arguably, the most important aspect of the new Escalade is its interior. When the redesigned Lincoln Navigator came out, it made the aging Escalade look like a boring dinosaur. Cadillac knew this interior had to be extraordinary to compete, and itÂ’s taken an interesting approach.  Do you recall the Cadillac Escala concept? If so, thatÂ’s exactly what Cadillac has done with the EscaladeÂ’s interior. The tri-screen layout of the EscalaÂ’s concept dash has been translated into a final production design, and it looks spectacular in person.

GM’s move to Woodward is the right one — for the company and for Detroit

Back in 2018, Chevy invited me to attend the Detroit Auto Show on the company dime to get an early preview of the then-newly redesigned Silverado. The trip involved a stay at the Renaissance Center — just a quick People Mover ride from the show. IÂ’d been visiting Detroit in January for nearly a decade, and not once had I set foot inside General MotorsÂ’ glass-sided headquarters. I was intrigued, to say the least. Thinking back on my time in the buildings that GM will leave behind when it departs for the new Hudson's site on Woodward Avenue, two things struck me. For one, its hotel rooms are cold in January. Sure, itÂ’s glass towers designed in the 1960s and '70s; I calibrated my expectations accordingly. But when I could only barely see out of the place for all the ice forming on the inside of the glass, it drove home just how flawed this iconic structure is.  My second and more pertinent observation was that the RenCen doesnÂ’t really feel like itÂ’s in a city at all, much less one as populous as Detroit. The complex is effectively severed from its surroundings by swirling ribbons of both river and asphalt. To the west sits the Windsor tunnel entrance; to the east, parking lots for nearly as far as the eye can see. To its north is the massive Jefferson Avenue and to its south, the Detroit River. You get the sense that if Henry Ford II and his team of investors had gotten their way, the whole thing would have been built offshore with the swirling channel doubling as a moat. This isnÂ’t a building the draws the city in; itÂ’s one designed to keep it out. Frost on the inside of the RenCen hotel glass. Contrasted with the new Hudson's project GM intends to move into, a mixed-use anchor with residential, office, retail and entertainment offerings smack-dab in Detroit's most vibrant district, the RenCen is a symbol of an era when each office in DetroitÂ’s downtown was an island in a rising sea of dilapidation. Back then, those who fortified against the rapid erosion of DetroitÂ’s urban bedrock stood the best chance of surviving. This was the era that brought us ugly skyways and eventually the People Mover — anything to help suburban commuters keep their metaphorical feet dry. The RenCen offered — and still offers — virtually any necessity and plenty of nice-to-haves, all accessible without ever venturing outside, especially in the winter, but those enticements are geared to those who trek in from suburbia to toil in its hallways.
