GM extending warranties on Cadillac CTS-V and Chevy Camaro ZL1 for supercharger issue

Okay General Motors, we've sat by and watched you recall the compact cars, crossovers and pickup trucks, and aside from reporting on it, we've been fairly quiet. This, though, this will not do. We can almost tolerate the recalls on the bread-and-butter cars, but leave the performance vehicles alone.
According to a report from The Car Connection, GM has discovered a problem with the superchargers of the 6.2-liter V8s found in the Chevrolet Camaro ZL1 and the Cadillac CTS-V. Apparently, the issue rests around the internal bearing shaft grease, which can become contaminated (we aren't sure with what). If left unchecked, it'll first lead to a rattle at idle, which goes away under slight throttle. The real warning stage is when a high-pitched squeal develops, signaling that the bearing shaft has failed. Naturally, severe engine damage is the next step (although it's possible that the engine will also just refuse to turnover, although neither case is desirable).
According to TCC, GM will replace the superchargers on vehicles that have exhibited symptoms of bearing shaft failure free of charge. It will also, allegedly, be extending the warranty on all supercharged ZL1s and CTS-Vs to 10 years or 120,000 miles (whichever comes first), from the date of purchase. Officially, only 2009 to 2013 CTS-Vs and 2012 to 2013 ZL1s are suffering from this issue.

Cadillac: The standard of what?

Cadillac's tagline "Standard of the World" goes back to 1908 when it won the Dewar Trophy. While you might think that the moniker and the trophy have something to do with a feat of racing and daring-do against a cadre of British, French, and German marques, it's nothing of the sort. Rather, Cadillac achieved the trophy because of interchangeable parts. The parts they were producing back then were so well-made that Henry Leland, who established Cadillac, was able to disassemble three Model Ks, mix up the parts, and then put together three functioning cars. This amazed the Brits who handed him the trophy, and the "Standard of the World" was born. During the past several months, Cadillac has been producing news releases that would seem as though the company is the Standard of the World: "Cadillac Global Sales Rise 44.2 percent in January ... 18 percent in February ... 22.1 percent in March. . .40.9 percent in April ... 33.8 percent in May ... 7.2 percent in June." Like the Dewar Trophy being about manufacturing not performance, things are not necessarily what they seem. That is, Cadillac's growth is predicated on performance in China, not in the US. Through June, its China sales are 80,357 vehicles for the first five months of 2017, versus 72,073 in the US. The China number is a 75.4-percent year-over-year increase while the US number is a 1.6-percent decrease. For the entire globe, Cadillac has sold 164,174 vehicles. Of them, 65,250 were the XT5. That was followed by the ATS, at 34,277 units. In the US, the XT5 is doing reasonably well, as it has moved 29,798 units during the first six months. The ATS, conversely, is doing not particularly well, as it is down 26.2 percent with sales at just 7,209 for the year so far. To put that into some sort of context, know that Cadillac has sold 7,370 copies of the generally derided XTS, which is down 24.7 percent. The CTS is down 36 percent at 5,059 units, and the only other car in the lineup (we'll pretend that the ELR doesn't exist anymore and it shortly won't), the CT6 sedan, is up 172.7 percent – but they have sold only 5,397 CT6s. While Caddy talks a good game about competing with the likes of the BMW 5 Series and the Mercedes E-Class, know that those two sedans have been sold 17,036 and 20,783 times this year in the US respectively. So what is Cadillac chief Johan de Nysschen to do? According to Reuters, it is to cull the lineup.

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.
