Cadillac CT6 production ceases January 2020 as part of D-Ham layoffs

General Motors filed paperwork under the Worker Adjustment and Retraining Notification Act with Michigan's Department of Labor and Economic Opportunity this week, detailing events to come at the automaker's Detroit-Hamtramck Assembly Plant. Starting February 28, 814 salaried and hourly workers at D-Ham, as its called, will be laid off. The 753 workers represented by the UAW will begin receiving offers in January to relocate to facilities in Michigan and Ohio, or buyout offers. As the 4-million-square-foot plant winds down through April 3 to a skeleton crew, the Cadillac CT6 ceases production in January 2020, and the last Chevrolet Impala comes off the line on February 28. The loss of the CT6 represents the end of Cadillac's latest brief, and highly regarded, adventure into flagship sedans. It might also mean the end of the 4.2-liter Blackwing twin-turbo V8 engine, at least for the moment. Both casualties are calamities. The death of the Impala closes the door on a nameplate in production for 52 years since 1957, having started off as a top-tier trim for the 1958 Bel Air known as the Bel Air Impala, once advertised with the line, "Lets you know you're the boss." As part of the new four-year labor agreement with the UAW, GM is keeping D-Ham open to build a new line of battery-electric vehicles, ultimately investing $3 billion and tripling employment to 2,225 workers when fully operational. The agreement described the coming EV as a "van" that would commence production in late 2021, but various reports say what's actually coming is a range of premium EVs in pickup and SUV bodystyles under the program codename BT1. The easy predictions put an electric GMC Sierra and Cadillac Escalade among the EV fold, but not until 2023, according to auto industry forecaster LMC Automotive. Before that, LMC claims an electric van will debut in late 2021, along with a battery-powered rebirth of the Hummer brand in pickup and SUV forms, also in late 2021. 

How Cadillac improved power output in 2016 ELR by 25 percent

Earlier this year, Cadillac announced that the 2016 ELR would come with a big price drop and a powertrain that packs 25 percent more power output. That's a lot more oomph, but it didn't sound like the Caddy engineers made any major changes to the engine or motors. So, what happened? Let's refresh our memories with the numeric details. The 2016 car is 1.5 seconds quicker to 60 miles per hour than the 2014 model (there was no 2015), down to 6.4 seconds. The 2014 put out 295 pound-feet of torque. For 2016, it will be 373 lb-ft. The specific breakdown of the various components in the powertrain has not been disclosed, but from what we can tell, the two electric motors and the 1.4-liter inline-four engine in the new ELR are not that much different than those in the old one. Sam Abuelsamid, senior research analyst at Navigant Research (and former writer here at Autoblog) said that any of the unspecified upgrades would be difficult to tell on a part-by-part basis, but the overall effect will be noticeable. "The changes to the ELR as I understand them are analogous to getting more performance out of a 1965 Mustang with the entry version of the 289 cubic-inch V8. You can replace the carburetor with a larger version that enables more air and fuel to flow into the engine, thus producing more power. The basic engine hasn't changed, but power capability is being unleashed by feeding it more." "Cadillac has changed components in the power electronics to enable more current flow into the motor and thus produce more torque. When you do this in the Mustang, you probably need to replace the rear axle gears and use a beefier clutch to transmit the power to the wheels. Similarly, the ELR probably has some upgraded clutches, bearings, and gears to withstand the increased total output." Cadillac spokesperson David Caldwell told AutoblogGreen in an email that the new ELR does indeed have more than just new lines of code. "One could not 'reflash' a previous ELR to get the performance of a 2016," Caldwell said. "If one only changed software you would not get the performance upgrade fully, as the 2016 creates higher current, more power. So these have been upgraded physically – hardware.

Cadillac planning its own engines, halo cars

Cadillac is in the midst of some big changes. It's got a new chief executive. It's taking some distance from parent company General Motors and moving to a new headquarters in New York. And it's instituting a new naming scheme that will allow not only for a more clear progression in its lineup, but also for more models. But that's not the end of the story. Not by a long shot.
Speaking with Automobile magazine, Cadillac's new president Johan de Nysschen revealed his intention to develop several new models and powertrains. For starters, he does not want Cadillac to continue borrowing engines from the GM parts bin, but intends to develop a new range of engines specifically for the luxury automaker. The program will likely start with smaller-capacity engines but eventually lead to new V8s as well, taking the place of the long-serving Northstar engine that finally ended its lifespan a few years ago after some two decades of production. Along with other technologies, de Nysschen envisions possibly sharing these powertrains with other GM divisions, but developing them first and foremost for Cadillac.
The bigger question, however, is where those engines would go, and de Nysschen had some thoughts to share on that front as well. For starters, the former Infiniti and Audi exec sees room for an even bigger sedan above the upcoming new CT6 that will cap the current range. Maybe even two of them. But that's not all. Johan wants to see Cadillac get (back) into the sports car game with a new halo model or two - something it hasn't really done since the Corvette-based XLR roadster. A pair of new crossovers are also said to be in the works, flanking the SRX on both sides with smaller and larger models.
