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.

Junkyard Gem: 1981 Cadillac Eldorado with V8-6-4 engine

Skyrocketing fuel prices caused by geopolitical events in 1973 and 1979 led to gas lines, federal fuel economy requirements, and an increasing reluctance on the part of American car shoppers to buy big, thirsty Detroit luxury machines. General Motors had pulled off some amazing technological feats in the past — the small-block Chevrolet V8 engine and Hydramatic transmission being two extraordinarily successful ones — and so Cadillac's bosses figured that a combination of computer wizardry and clever mechanical engineering would give the 368-cubic-inch Cadillac V8 a cylinder-deactivation system and resulting superior fuel economy. Here's a very rare example of one of those 1981 Cadillacs, found in a California self-service wrecking yard. The idea behind the V8-6-4 was that computer-controlled solenoids would physically disengage the rocker arms for one or two cylinders on each engine bank under low-load conditions, converting the engine from a 368-cube V8 to a 276ci V6 or 184ci V4 (that's 6.0, 4.5 or 3.0 liters, respectively, for the metric-system aficionados among us). This sort of variable-displacement magic is commonplace today, but it was science-fiction stuff in 1981. An "MPG Sentinel" display on the dash would let the driver know how many cylinders were active at the moment, and the car would get Chevy Citation fuel economy with Cadillac luxury. The V8-6-4 was the standard engine in all 1981 Cadillacs (except for the Seville, which had the troubled Oldsmobile diesel engine as the base powerplant and the V8-6-4 as an option). Unfortunately, the V8-6-4 worked about as well as the Oldsmobile diesel: very poorly. Within a few years, most owners of these engines had disconnected the rocker-deactivation solenoids and just drove their cars as regular full-time V8s. This one has the snazzy "Cabriolet Roof Treatment" option, which boasted "textured elk grain" vinyl and could be had in one of 17 available colors. Front-wheel drive gave the early-1980s Eldorado plenty of interior space, despite its more proletarian Olds Toronado origins, and these velour-covered seats made for very comfortable road trips. The price tag started at $17,550, or about $51,650 in 2019 dollars. The 1981 Imperial went for $18,311, and that car was based on the same platform as the lowly Plymouth Volare. Meanwhile, A BMW 733i cost $28,945 and a new Toyota Cressida a mere $11,599. The 1981 Cadillacs were just a little too much ahead of their time, it turned out.

Cadillac ELR regen on demand brakes win 2014 Green Car Technology award

Just like the Oscars, Green Car Journal decided a few years ago to up the number of nominees for its annual award. For the annual "Green Car of the Year" award, given out at the Los Angeles Auto Show each year, there are five finalists. For the "Green Car Technology" award, there are a fantastic ten. At the 2014 Washington Auto Show today, the Cadillac ELR and its regen on demand brakes managed to beat out the nine other finalists to claim the second annual "Green Car Technology" award. What is the purpose of the "Green Car Technology" award? Green Car Journal says it wants to reward "technologies that enable significantly improved environmental performance in vehicles today," which is why only fuel-saving technologies that were "in use on American highways during the award year" can be considered. The Caddy's brakes beat out the Acura Sport Hybrid SH-AWD powertrain, the Audi 3.0-liter turbodiesel engine, the BMW carbon-fiber passenger shell from the i3, the 1.0-liter EcoBoost engine used by Ford, the plug-in hybrid powertrain in the Honda Accord, Hyundai's hydrogen fuel cell technology, the regenerative brakes in the Mazda i-ELOOP, the plug-in hybrid powertrain used in some Porsche models and, finally, the Ram 3.0-Liter EcoDiesel engine. Last year, Green Car Journal gave Mazda's Skyactiv technology the inaugural Green Car Technology award. Cadillac ELR Regen On Demand Wins 2014 Green Car Technology Award Green Car Journal Lauds Cadillac's Electric Car Tech at Washington Auto Show WASHINGTON, Jan. 22, 2014 /PRNewswire/ -- Cadillac's innovative Regen on Demand technology has taken top honors as the winner of Green Car Journal's 2014 Green Car Technology Award™. The prestigious award was presented at a Green Car Journal press conference during the Washington Auto Show's second Policy Day. "Cadillac has cleverly evolved a common electric-drive efficiency system into an intriguing feature that adds a new dimension to the driving experience," said Ron Cogan, editor and publisher of Green Car Journal and CarsOfChange.com. "Ever-increasing efficiency is crucial to our driving future, yet efficiency itself is not an attraction for a great many car buyers.
