Johan de Nysschen tells his side of the story

Automobile snagged time with ex-Cadillac, Infiniti, and Volkswagen of America boss Johan de Nysschen. General Motors decided to part ways with de Nysschen on April 18, 2018, after the German spent four years in charge of America's luxury brand. The longtime auto exec is a polarizing figure for enthusiasts, who seem to take a mostly negative view of his work at Infiniti and Cadillac. However, there's no denying de Nysschen is frank, and in the Automobile interview he puts an insider's perspective on a big bag of issues we can only speculate on. One of the biggest bombshells in the interview was that it wasn't de Nysschen's idea to move Cadillac to New York: "When I was recruited, I was informed that the company would relocate to New York," he said. Previous GM CEO Dan Ackerson had made the decision before hiring de Nysschen, then Ackerson let his new hire make the announcement. The big change came only two years after de Nysschen had taken over Infiniti after insisting Nissan's luxury brand move to Hong Kong. De Nysschen explained Cadillac's NYC move with the same rationale as Infiniti's Hong Kong move, so everyone assumed the new guy was doing his usual. He explains in the interview that after the move, "Folks who rooted for Detroit felt betrayed. Cadillac had an enemy." And that became a problem. He has nothing bad to say about GM or Cadillac, believing on the contrary that "GM is in a good position going forward." But he brought clarity to some of Cadillac's struggles. Among the issues was GM's "very vigorous" post-bankruptcy test for green-lighting a project. Another was the lack of specialization for the luxury arm. "Engines were generically developed with the Chevy brand in mind," he said, "and, then, 'Okay, well, yeah, it's good enough for Cadillac.'" That carried over into haphazard technology rollouts. "GM didn't have a specific technology roadmap aligned to particular brands," he said. "The process was, as they were developing new technologies, they would look at what product's launch date would be aligned with the maturation date and market readiness of a technology and go with it, whether Buick, Chevy, or what have you." De Nysschen worked to end such generalized approaches, which is how we get Cadillac taking the GM lead on technology and electrification.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Cadillac clears camo off the XT3 revealing grille, lighting details

Up until now, every Cadillac XT3 we've seen has been buried under covers and vinyl wraps, but one of our spy photographers recently captured a group of them with significantly less camouflage. As a result, we finally get a relatively clear picture of what the car will look like. The nose blends the look of current Cadillacs with cues from last year's Escala concept. The headlights still appear to stretch up into the top of the fenders like its production brethren, but they don't descend as far down the front fascia, a hint of Escala influence. The grille also features more of egg-crate mesh like that Cadillac concept. In profile, we can see evidence of the XT3's smaller size compared with the XT5, mainly in the lack of any glass area behind the rear door. Other evidence of the smaller size is that our spy photographer reports the cars were being tested alongside the BMW X3 and Mercedes-Benz GLC-Class. The profile also shows that the XT3 will have a hard-edged rear end with a rakish hatch. At the back, there isn't a whole lot to report, but the taillights look like they'll be interesting. There appears to be a horizontal element in the middle of the hatch similar to what we've seen on the Escala and the refreshed XTS. We can also see some lights up on the C-pillar, which indicates that the XT3 will also have tall vertical elements up those pillars like on the Escalade. We expect the XT3 to show up late in 2018. It will likely be powered by a turbocharged four-cylinder of some sort, and because it will probably be based on an existing GM crossover or sedan platform, it will probably have front-wheel drive and/or a front-drive based all-wheel-drive system.
