Cadillac dealers frustrated over Escalade production snarls

Lincoln went through it during the launch of the MKZ last year, Jeep went through something similar with its Cherokee launch, and now the 2015 Cadillac Escalade has apparently caught the bug: dealer delivery delays because of quality control checks. Automotive News reports that Cadillac dealers have been waiting three times longer than usual - a month or more - from the time an Escalade leaves the assembly line to when it gets delivered. Worse, dealers are saying they don't always know where their vehicles are in transit, or when they are set to arrive. The situation has upset customers who have put down deposits and things have gotten so bad that some dealers have reportedly stopped taking pre-orders.
Cadillac says it has the delay, called "dwell time," down to two weeks, and it expects to cut that to a week by the beginning of September. The company said "a lengthy quality-assurance process on some interior parts" has caused the lag, the report citing additional issues with figuring out which vehicles should be delivered first. A spokesman said that more trucks have been put in the distribution system to work through the backlog, but it's clear it's still going to take some time to set things right, with one dealer telling AN that cars ordered in February and March still haven't arrived.
Brand chief Kurt McNeil said additional personnel are at the Escalade's Arlington, Texas factory to speed up the checks, and spreadsheets tracking every order have been distributed to field staff. Even with the snafu, though, the Escalade is Cadillac's best seller through July.

Weekly Recap: Auto execs face life in prison for recall delays under proposed legislation

The stiff punishments are part of broader transportation legislation, but clearly McCaskill has automakers in her sights.
Missouri Senator Claire McCaskill threw down the gauntlet this week, proposing a bill that could send auto executives to prison for life if they were found to have delayed a recall. She also wants to eliminate the limit for fines for auto safety violations, which are currently capped at $35 million.

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.
