Reuss says Cadillac CT6-based Buick could happen

Could the upcoming Cadillac CT6 and its Omega platform spawn a Buick variant? According to General Motors' product chief Mark Reuss, it could potentially be in the cards, but "not yet." "We're working on that," Reuss told Automotive News at the 2015 New York Auto Show. While there hasn't been a large, rear-drive Buick on dealerships since the Roadmaster in 1996, the company gave a big hint that it could head in that direction with the Avenir Concept, shown earlier this year at the Detroit Auto Show. As Automotive News explains, a rear-drive Omega-platform Buick could be a real hit in China, where consumers buy 13 Buicks for every one Cadillac. That move would be a big help to GM's bottom line, too, as it'd significantly increase the Omega platform's economy of scale. If a large Buick based on the CT6 were to head to China, though, it likely wouldn't be a simple case of badge engineering (thank God). Reuss hinted to Automotive News that while the mixed-material construction of the CT6 platform "is very flexible," doing an "identical version of that platform or not is a different conversation." What are your thoughts? Should Buick adopt the Omega platform for an Avenir-based sedan? Should that vehicle be sold here in the US, or should it be a China-only offering? Have your say in Comments.

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 adds torque-number badging to most new models starting in 2020

Few phrases describe huge swaths of America better than a phrase spotted on the back of a top-fuel dragster at an NHRA event: "You can never have too much horsepower or ammunition." If Cadillac CEO and wily Canuck Steve Carlisle has his way, the revised phrase would substitute "torque measured in Newton-meters" for "horsepower." Starting with the 2020 model year, America's luxury brand will add torque figure badges to CT and XT models, beginning with the XT6. The badge above kinda almost sorta represents the torque produced by the luxury crossover's 3.6-liter V6. That badge did not appear on the XT6 we photographed at the Detroit Auto Show. In U.S. parlance, twist in the XT6 comes to 271 pound-feet. Translated to Newton-meters, that's 367 Nm. Then round that up to the nearest 50, which Cadillac will do, and one arrives at 400. True, the rounding prevents a future of number jumbles like the 2020 XT6 367 vs. the 2021 XT6 419T. Nevertheless, we don't know why Cadillac is rounding to the nearest 50 instead of the nearest 25, since 50 Nm is about 37 lb-ft and could conceal a decent torque increase between model years. A "T" denotes turbocharging, and we imagine there'll be designations for hybrids and electric cars. We think most modern attempts at engine-based nomenclatures soon get as complicated as ciphers or come unmoored from their original scheme. And based on our experience with The Average Car Buyer, they don't care. A bigger number, no matter what that number represents, means more, which is the important thing. Because America, right? Maybe not. Carlisle said, "We're not talking about displacements any more," and the new badging will give consumers "a clear understanding of the power differences across the lineup." The brand believes torque provides a better comparison between ICE, hybrid, and EV powertrains and "the balance between fuel economy and performance." As for the immigrant unit of measurement, Carlisle told CNET, " It's metric, it's universal, it's global, we have to think about all the markets that we're doing business in." Oh, and, "Engineers certainly prefer Newton-meters." The new nomenclature will not be applied to V-series models or the Escalade, because the CEO holds that "special cars get special names." We should probably take a moment to reassure the CT and XT models that Steve Carlisle thinks you're all special, too. Just a different kind of special.
