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.

GM cutting production at two plants

General Motors is continuing to adjust to excess supply of some of its brands' models. To get production more in line with the vehicles' actual demand, the automotive giant is idling two of its factories in North America in the coming months. The Orion Assembly plant is going to be down from March 9-13, according to an anonymous plant worker and another insider speaking to Automotive News. The factory builds the Chevrolet Sonic and Buick Verano, but there are plenty of both models sitting on dealer lots, including 216 days worth of Sonics, according to AN. The factory already had two idle periods announced to reduce the excess. In addition, downtime is scheduled at GM's "Flex" line at the Oshawa, Ontario, Canada, plant from April 13-17. This affects supply of the Chevrolet Camaro, Impala, Buick Regal and Cadillac XTS. Among them, the automotive giant has the largest supply of Regals ready for dealers with 213 days worth of them, according to AN. The future for the whole Oshawa factory is cloudy in general, though. There are rumors that it could close entirely in the future because the Camaro is leaving and the Regal and XTS might not last much longer than 2017. The Canadian government and the labor union there intend to put up a fight, though.

Why GM will import the Cadillac CT6 PHEV from China

There's a clear-cut reason that General Motors is going to build its upcoming plug-in hybrid CT6 sedan in China. Sure, the car will be sold in China and the US, but the real reason for the "Made In China" stamp is environmental. If an automaker wants to build a new model in China, adding a green powertrain is an easy way to do that. The CT6 will have both a PHEV option as well as standard gas engine versions. David Leone, Cadillac's executive chief engineer, told AutoblogGreen recently that, "[China is] far more receptive to approving localized production of vehicle programs that have new energy vehicle powertrain applications." To put it succinctly, since the CT6 has a PHEV option, it is easier for GM to build all CT6 models in China. Some of them will then be imported to the US. "Most new global Cadillacs will also be produced in China as well. It's our second-largest market in the world." "To bring any new car into China, to produce it, you need government approval," Leone said. "The government isn't interested in bringing many new cars to market that don't have new energy credits. [The CT6] also provides new energy credits that enables it to be an attractive, well-received product in China." Leone said that there are two main markets for the various CT6 models: China and the US. The car will arrive in the 2017 model year, so some time after the end of June 2016. There are other practical reasons to build the PHEV in China, like the cells in the battery pack. Those are provided by LG Chem, which makes some cells in Michigan but more in South Korea. And GM already builds cars in China through its joint venture with SAIC, Shanghai General Motors, or SGM. "In February 2013 we started making the XTS, in summer of 2014 we started making the ATS-L," Leone said. "We will be producing [the CT6] within a number of months. Most new global Cadillacs will also be produced in China as well. It's our second-largest market in the world." The Chinese and US versions of the CT6 will be identical, Leone said. While some Cadillacs sold in China are slightly different than the US versions – the Chinese ATS is 77 millimeters longer, for example – the CTS6 PHEV will be exactly the same in both places, other than slight tweaks to the trim levels. Still, "more of our cars going forward will be the exact same car," he said. That doesn't mean that sales will be the same everywhere.
