GM recalling 8.4M cars, 8.2M related to ignition problems

General Motors today announced a truly massive recall covering some 8.4 million vehicles in North America. Most significantly, 8.2 million examples of the affected vehicles are being called back due to "unintended ignition key rotation," though GM spokesperson Alan Adler tells Autoblog that this issue is not like the infamous Chevy Cobalt ignition switch fiasco.
For the sake of perspective, translated to US population, this total recall figure would equal a car for each resident of New Hampshire, Rhode Island, Montana, Delaware, South Dakota, Alaska, North Dakota, the District of Columbia, Vermont and Wyoming. Combined. Here's how it all breaks down:
7,610,862 vehicles in North America being recalled for unintended ignition key rotation. 6,805,679 are in the United States.

Cadillac Celestiq flagship EV shows off its tint-shifting smart roof

GM has high hopes for its upcoming Cadillac Celestiq sedan, slated for release in 2023. The flagship EV is being built to help the brand recapture its reign as “the Standard of the World.” As such, itÂ’s expected to arrive packed to the gills with cutting edge, futuristic technology including an all-glass roof that can adjust its opacity anywhere between crystal clear and completely opaque with the mere flick of a switch. These roofs, dubbed SPD-Smartglass, have been designed and manufactured by Research Frontiers of Woodbury, New York, and are based on Suspended Particle Device technology that was originally created as a replacement for the manual sliding window shades aboard commercial aircraft, Research Frontiers CEO Joe Harary told Engadget. Some of the earliest examples of SPD window treatments can be seen on the 2011 Mercedes Benz SLK roadster and in the 2012 Mercedes S Class coupe, which were used to increase headspace while eliminating the physical window shade screens, as well as various McLaren models over the past decade. As the YouTube video below explains, Research Frontiers SPD tech relies on polyiodide nanoparticles to generate its tint effect. Magic Sky Control Using SPD-SmartGlass Technology “SPD technology is smart glass that allows you to change the tint of the glass,” Harary explained. “There's this film that we invented that has little nanoparticles in it, which you can control with a small electrical voltage. So, basically this film... that allows you to dial in whatever tint level you'd like.”  “The crystals are about three to five tenths of a micron in length and they act as induced dipoles so when you apply an electric field to conductive coatings in the film,” Harary continued, “ the particles will line up, and allow light to pass through. Then, when you remove the voltage, their natural tendency is to be in the dark state due to Brownian movement and that causes the glass to tint.”  As the tint partially blocks incoming photons, it also reduces the amount of glare experienced by the driver and the heat trapped within the vehicle — over 99.5 percent of light and 95 percent of heat, per a January press release from the company. The claim is, this allows vehicle occupants to stay comfortable for longer without having to turn on the A/C, as well as keep the interior up to 18 degrees Fahrenheit cooler overall, Harary said.

2020 Cadillac CT6-V First Drive | A new kind of V

One of the weird tidbits of car news in the past year was the change in naming for the 2020 Cadillac CT6-V. When it was first revealed, it was called V-Sport, the term previously used for Cadillacs with more moderate performance upgrades than the full-blown V cars that possessed massive power outputs and serious track-going capabilities. But then, before the car in question went on sale, Cadillac changed the name to match the equally moderately sporty CT4-V and CT5-V that officially downgraded the V name. So what should we make of this CT6-V, then? Is it a hardcore performance machine like the old V cars? Or is it what we’re expecting of the new V cars: a lightly upgraded version of the base car that isnÂ’t particularly distinguished? As it turns out, the CT6-V sits between these two extremes to create a car thatÂ’s involving and exciting for the driver without compromising the CT6Â’s refinement and luxury. Mechanically, the CT6-V is ultimately closer to its full-bore V predecessors. The highlight is the “Blackwing” twin-turbocharged 4.2-liter V8 that makes 550 horsepower and 640 pound-feet of torque. Besides giving the engine prodigious output, Cadillac borrowed some pages from the AMG handbook: the turbocharger is nestled in between the cylinder heads, just like the current 4.0-liter AMG V8, and each engine is hand-built start to finish by one of six engine builders. The builderÂ’s name is even featured in the engine bay. TheyÂ’re special details that fit the idea of the old V cars, but the fact that a version of the same engine is in the Platinum CT6 does make its inclusion in the CT6-V seem less special, even if its output is notably less at 500 horsepower and 574 pound-feet of torque. Setting aside the details, the engine performs well in the real world. ItÂ’s astonishingly smooth, exactly what you want from a fast flagship. It also emits a unique exhaust note thatÂ’s both raspy and growly. You wonÂ’t mistake it for a pushrod powerplant. The power and torque provide a prominent push at all points in the rev band after a brief moment for the turbos to spool up. ItÂ’s just a shame there isnÂ’t much of a rev band, as the engine redlines at 6,000 rpm, which is easy to hit thanks to the engineÂ’s creamy character. ItÂ’s so low one wonders why Cadillac bothered developing a double-overhead-cam engine at all. The V8 is coupled to a 10-speed automatic transmission and all-wheel drive. The 10-speed is perfectly fine when cruising around town.
