Cadillac LTS flagship to bow at NY Auto Show

There is widespread agreement across the industry that Cadillac needs a proper, rear-drive flagship sedan that completes legitimately with the Mercedes-Benz S-Class, Audi A8 and BMW 7 Series.
Fortunately, the same view is held within the company, and just such a car - possibly dubbed LTS - is under development. According to a high-level source at Cadillac, the new four-door, which is said to incorporate design cues from the marque's celebrated Elmiraj coupe concept, will debut at the New York Auto Show next April.
If the car needs a cheerleader, surely incoming president Johan de Nysschen is just such a person. De Nysschen doesn't arrive at Cadillac until late in the month, but certainly he will want a proper flagship to do battle with his old foes at Mercedes-Benz and BMW and old friends at Audi and Infiniti.

GM winding down Chevrolet brand in Europe

If you've taken even a cursory look at GM's European strategy and wondered how it can target the market there with both Chevrolet and Opel/Vauxhall, you're not alone. In fact General Motors itself has found it difficult to justify the two-pronged approach. That's why it's essentially pulling Chevy from the European marketplace.
Instead of trying to ply European buyers with what are mostly former Daewoo products rebadged as Chevys, GM will now let Opel (or Vauxhall in the UK) represent its mass-market aspirations. Chevrolet will keep its presence in Russia and other former Soviet markets, and will continue selling certain niche products in Eastern and Western Europe. The Corvette, for example, has long been sold in Europe through Cadillac dealerships, which for its part is currently "finalizing plans for expanding in the European market".
While the shift in strategy is expected to help GM get a stronger foothold in the European market in the long run, in the short term the restructuring will cost it dearly: between $700 million and $1 billion, according to its own estimates, split between the last quarter of this year and the first half of the next.

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.
