Cadillac's Johan de Nysschen clarifies a few points on the brand's future

Last week, Motor Trend ran coverage on a journo roundtable with Cadillac president Johan de Nysschen. During the roundtable, de Nysschen cited a few reasons for the decline in sedan sales, including gas prices, "young consumers" — read, millennials — less interested in driving dynamics than lifestyle accessories, and the state of U.S. infrastructure. Jalopnik homed in on the last two reasons, and those became the story, including here in our post on the roundtable. So de Nysschen called Jalopnik to add more context. The original reaction pieces painted de Nysschen's rationales as an excuse for sporty sedans not selling well, when the issue is Cadillac's sporty sedans not selling well. His main clarification: "I wasn't advocating the idea that the world is black and white, that if you're a young buyer a millennial or a teenager that you don't enjoy driving." On that note, it would be ridiculous to deny millennial and sedan-segment bugbears; de Nysschen has market research and the industry-wide, rabbit-like crossover breeding program to back him up. Yet even as he touted the success of the XT5, noting that it's "the third-best-selling luxury nameplate in the U.S. after the Lexus RX, and the Mercedes C-Class," he could add, "But the irony is not lost on me that the C-Class is a sedan." The circumstances laid out in the follow-up piece inject more likely color into the situation: the brand's onetime, singleminded focus on the U.S., followed by a singleminded focus on China that left the U.S. market wanting for attention. We could add to that: years of lackluster products and awful attempts at volume and brand engineering under the old GM at the same time that downsized premium luxury products, crossovers, and SUVs began their rocketship trajectories; trying to live off the Escalade success; and the carmaker's desire not to offend its older, traditional buyers while concurrently wooing "coastal influencers." De Nysschen also acknowledged that Cadillac interiors aren't where they need to be, saying, "We recognize that's where we want to improve." The result, as de Nysschen put it, "We're playing with the hand that we've been dealt.

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.

GM pauses 3.0-liter turbodiesel production due to a supplier shortage

General Motors confirmed it has temporarily stopped taking orders for trucks and SUVs equipped with the 3.0-liter Duramax turbodiesel six-cylinder engine. It blamed the last-minute pause on a supplier-related shortage. Website TFL Truck first reported the news, and a representative from General Motors quickly confirmed it. The spokesperson explained the issue is due to a "temporary part shortage" and added that production will resume "as soon as possible," meaning the Duramax engine (which is called LM2 internally) is not going away permanently. Additional details are not available, so we don't know if the issue is related to the ongoing chip shortage. Rather than delay deliveries and create a backlog, General Motors is reportedly asking its dealers to encourage buyers who want a turbodiesel engine to instead select either the 5.3-liter V8 or the 6.2-liter V8, depending on the model selected. Both are gasoline-powered units. There's no word yet on when Duramax production will resume. The shortage affects several models, including Chevrolet's Tahoe, Suburban, and Silverado 1500 and GMC's variants of these trucks. Cadillac's Escalade is temporarily diesel-less as well. Heavy Duty variants of the Silverado and the Sierra are not affected because they're powered by a different Duramax engine with eight cylinders. Motorists seeking a full-size SUV powered by an efficient turbodiesel engine are temporarily out of options because the Tahoe/Yukon and the Suburban/Yukon XL had the segment to themselves. The Duramax was surprisingly popular, too: in May 2021, GM Authority reported that the turbodiesel straight-six represented 8% of Suburban sales and 6% of Tahoe sales. Installed in a rear-wheel-drive Tahoe, the engine returns 21 mpg in the city, 28 mpg on the highway, and 24 mpg in a combined cycle, figures that make the body-on-frame behemoth more efficient than the unibody, front-wheel-drive Chevrolet Blazer that's 20 inches shorter and approximately 1,700 pounds lighter.
