Cadillac tipped to call flagship something other than LTS

Cadillac wouldn't be Cadillac without large sedans in its lineup, and while the XTS has had to hold down that end of the fort all on its own, it won't have to for too long. That's because the luxury brand in the General Motors portfolio is preparing to roll out its new LTS, stylistically previewed by the Elmiraj concept pictured above. Only now, the latest thinking is that the upcoming flagship model may not be called LTS at all.
As Automotive News points out, Cadillac's naming scheme is all over the place at the moment. The ATS slotting below the CTS makes sense (alphabetically), but where do the ELR, SRX and especially the Escalade fit into that naming hierarchy? And how would LTS - as the project has been known until now - sit above the XTS?
Fortunately, Cadillac may be on the case, as two of the division's most recent senior appointments seem keen to rationalize the naming scheme. One is Uwe Ellinghaus, who joined Cadillac as chief marketing officer late last year. Speaking of the brand's nomenclature last spring, Ellinghaus was quoted as saying, "We are aware that this is currently a weakness of the Cadillac brand." And his new boss is bound to agree.

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 toned down ATS Coupe design due to customer feedback [w/poll]

Automakers always face a difficult decision when it comes to styling their cars. Design them too blandly and nobody will get excited about them. But style them too aggressively and they'll often end up turning off potential buyers.
Cadillac, for its part, is no stranger to aggressive design, but when it came to the new ATS Coupe, it elected to tone things down a bit. Speaking with The Detroit News in a wide-ranging interview, Cadillac design director Bob Boniface revealed that the original design for its compact coupe was edgier - closer to that of the CTS Coupe - with a wedgier profile, a more steeply raked beltline and a more severe grille. But potential customers surveyed in clinics apparently didn't like it. They found it looked heavy, inefficient and not fun to drive. So Boniface and his team literally went back to the drawing board and "took as much visual mass out of the car as [they] could." The resulting coupe, while handsome, looks far more similar to its four-door companion than did Cadillac's CTS.
