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.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

Cadillac to launch Super Cruise semi-autonomous technology in two years [w/video]

We all know that self-driving cars are coming. It's not so much a question of If so much as When. And when it comes to General Motors products, we now have something of a date to work with, as Cadillac has announced plans to roll out what it is calling Super Cruise technology in an unnamed new model within the next two years. As you would expect, this new tech can speed the car up, slow it down and keep it in its intended lane, but GM isn't expected to release a fully self-driving car, saying that it will still require "an attentive driver."
We're not quite sure what new model Cadillac will use to launch this new technology, but our best guess would be its upcoming LTS sedan. Other possibilities may include a new crossover - we've heard rumors of CUVS coming from Caddy both above and below the current SRX - or entry-level sedan, but those seem less likely than a high-dollar flagship like the LTS.
The next techy bit of kit currently being shown off by Cadillac engineers includes vehicle-to-vehicle and vehicle-to-infrastructure communication, technology which would seemingly allow cars to travel in close proximity to one another, with less danger of collisions. According to our friends at Engadget, GM is working with the University of Michigan to outfit some 120 miles of roads in and around Detroit, MI, with the requisite sensors to make all this technology possible.
