GM invests $175 million to replace 3 Cadillac sedans with 2

We've already had confirmation that Cadillac is sunsetting the ATS compact sedan and strong hints that Caddy would discontinue the full-size XTS (pictured above) and midsize CTS, too. Now all three are confirmed, with GM saying it's investing $175 million to build two replacement sedans. GM has already begun installing new tooling at its Lansing Grand River assembly plant in Michigan. That will go toward building two new sedans, which reports suggest are likely to be called the Cadillac CT5 and CT4, or possibly the CT3. It's part of Cadillac's plan to introduce a new vehicle every six months by the end of 2021. A spokesman told the Associated Press that the new cars will debut within that time frame and that the changes won't affect staffing levels at the plant, which employs 2,000 people. Of the three, the XTS is expected to go away entirely, while the CT5 would replace the CTS, straddling the line between a compact and midsize four-door. The CT4 or CT3 would take the spot of the ATS and likely be smaller. That would leave the CT6 as the brand's largest sedan and leave Cadillac with three sedans starting with the 2019 model year. Meanwhile, Cadillac has only one model, its top-selling XT5, representing the all-important and red-hot luxury crossover segment. It's prepping a midsize XT4 crossover for sale later this year as a 2019 model. Cadillac's global sales rose 15.5 percent in 2017, thanks largely to growth in China, but sales in the U.S. fell 8 percent for the year to 156,440 vehicles. Sales of the ATS fell 39 percent, dropped 35 percent for the CTS and 27 for the XTS last year. Related Video:

GM says over 40% of new China launches in next five years will be EVs

SHANGHAI — General Motors is planning an electric car offensive in China with more than 40% of its new launches in the country over the next five years set to be electric vehicles (EVs), the U.S. carmaker said on Wednesday. GM's electric vehicles, many of which will be all-electric battery cars, will be manufactured in China with almost all parts coming from local suppliers, the company said in a statement released at its Tech Day event in Shanghai. Reuters reported earlier on Wednesday that GM was planning to overhaul its Chinese line-up to stem a slide of sales after more than two decades of growth in a country that contributes nearly a fifth of its profit. GM's new China boss Julian Blissett told Reuters that new technologies, such as EVs and cars with near hands-free driving for highways, would play a key role in GM's China initiatives, which are part of a push to get annual sales in the country back to the 4 million peak it hit in 2017. GM did not say in its statement how many new or significantly redesigned models it was planning to launch in China over the next five years. "China will play a crucial role in making our vision a reality," GM CEO Mary Barra said in the statement, referring to its initiative to create what it describes as a future of "zero crashes, zero emissions and zero congestion" through electrification and smart-driving technologies. GM has said it plans to invest more than $20 billion in electric and automated vehicles globally by 2025. It was not clear how much of that investment will be spent in China.

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.
