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.

GM claims it's first to sell million 30+ mpg vehicles

As we continue to put together all the data for the year-end edition of By The Numbers, General Motors has announced that it sold more than a million vehicles in the US last year that achieved at least 30 miles per gallon on the highway. More impressively, GM managed this feat using multiple strategies including small vehicle size, turbocharged engines and hybrid or plug-in technologies across four brands (Buick, Cadillac, Chevrolet and GMC) accounting for 13 separate models. This number will grow even more in 2013 thanks to cars like the all-electric Spark, the diesel Cruze, the range-extended Cadillac ELR and the Buick Encore compact CUV.
GM's small car sales were up 39 percent last year helping to attain this million-sales mark for 30-mpg models, and almost 40 percent of all GM sales consisted of cars with fuel-efficient I4 engines. In regards to more advanced means of improving fuel economy, GM says that it plans on having 500,000 vehicles with "some form of electrification" on the road by 2017.

Junkyard Gem: 1993 Cadillac Allante

The General's Cadillac Division had lost much of its status as a world-class styling and engineering innovator by the 1980s, while younger rich Americans signed on the line which is dotted for European luxury machines packed full of futuristic technology. Something needed to be done to win back the hearts of those buyers, and that something was the Cadillac Allante two-seater. Here's a final-model-year Allante, complete with one of the very first Northstar V8 engines, found in a Denver yard. The overhead-valve Cadillac V8 engine of 1949 shook up the automotive world, and the double-overhead-cam Northstar V8 of 44 years later had a similar effect. Finally, a high-revving, smooth-running modern V8 to compete with those pesky European and Japanese carmakers! Only the Allante got the Northstar at first, with other Cadillac models following soon after. After the underwhelming power output of the pushrod HT4100 V8s used in the 1987-1992 Allantes, the upgrade from 200 horses to 290 helped boost sales of the '93 to the highest annual figure ever achieved by the model: 4,670 cars. Unfortunately for GM, production costs of the Allante proved to be murderous in the long run. Shortened Eldorado frames were loaded onto specially-fitted 747s in Detroit and flown to Pininfarina's new Allante factory in Italy. After Pininfarina built the bodies, they got loaded onto the 747s, flown back to Detroit, trucked to the Hamtramck assembly plant, and given running gear there. GM called this system the "Allante Air Bridge" and it cost plenty. The cars looked both futuristic and Italian, which they were, but the Allante's price tag stood at heights far above those of the rest of the Cadillac line: $59,975 in 1993, or about $108,500 in 2020 dollars. You could buy a rear-wheel-drive BMW 850Ci with a 282-horse V8 and manual transmission for a mere 10 grand over the Allante's cost that year, or a Jaguar XJS convertible for just $56,750. The Allante had front-wheel-drive and a not-so-modern four-speed automatic transmission, which hurt sales among the enthusiast types who flocked to Cadillac showrooms for the CTS-V a decade or so later. No European machine of 1993 could top the Mars Base appearance of these vertically-arranged, all-pushbutton HVAC/audio controls, though.
