Cadillac Elmiraj sedan RWD flagship finally caught testing

While we still have no insight as to it being named Elmiraj, STS or some other permutation of the -TS nomenclature ("LTS" has apparently been registered by GM, as well), new spy shots give us proof positive that Cadillac is indeed hard at work on a rear-wheel-drive flagship model. Spied for the very first time in some north country testing, these shots provide a first look at the upcoming range-topper from Cadillac.
Impressively long and large bodywork ride atop new General Motors' corporate Omega rear-drive architecture here. Heavy cladding over camouflage may discourage finding any details, but the overall, sharp-edged and blocky design is clearly reminiscent of what we've seen on the new CTS and the recently debuted ATS coupe. A strong, wheels-at-each-corner stance helps emphasize the length of this stretched Caddy, and everything about the proportions seem spot-on for a new fullsize flagship for the brand.
It's quite possible that Cadillac will ultimately festoon this large sedan with detailing reminiscent of the original Elmiraj coupe, though thus far we've only seen prototypes wearing four-doors.

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.

GM will recall more than 3.3 million vehicles in China for suspension defect

BEIJING (Reuters) - General Motors' joint venture in China, Shanghai GM, will recall more than 3.3 million Buick, Chevrolet and Cadillac vehicles stating Oct. 20 because of a defect with the suspension system, China's market regulator said on Saturday. GM Shanghai said in a text message to Reuters that the suspension arm may be deformed under extreme operating conditions, but there are no known casualties related to the issue. The recall includes cars produced between 2013 and 2018, the State Administration for Market Regulation said in a statement. GM will contact those affected and repair the vehicles free of charge, it said.
