Cadillac's Blackwing V8 was the best engine at the worst time

It should be clear that GM knows how to innovate and engineer excellent products when it wants to. Cadillac's 4.2-liter twin-turbo Blackwing V8 is recent proof of that. Yet, as related in an extensive Road & Track piece, the Blackwing became victim to some of The General's bugbears, like the reticence to — for whatever reasons — unleash its excellence everywhere, fund that excellence, and be consistent with that excellence over the long term beyond the Corvette and full-sized pickups and SUVs. The R/T story relates tales told by "several people deeply involved with the Blackwing project" about how an engine 18 years in the making was deprived of its reasons for being in less than three. Starting around 2000, GM spent a dozen years building Cadillac up to the point where the American luxury brand could rationally flip to the chapter called, "Taking the Fight to the Germans, but for Real this Time." The first steps in the plan meant an exclusive platform and an exclusive engine. The platform was called Omega. You know the engine's name. They were going to be the aluminum-blocked fist and velvet glove enabling Cadillac to break on through to the other side of luxury — proper luxury to global standards, that is — with a range of beautiful and dynamic crossovers and sedans. An engineer involved in the project estimates GM poured $16 million into the Blackwing's clean-sheet development. Many more seven-figure sums went into creating the first sedan on the Omega platform, the CT6. The automaker dropped millions again poaching ex-Audi and Infiniti chief Johan de Nysschen, and moving Cadillac's headquarters to New York City in 2014. Further pallets of cash funded the development and debut of the Escala concept at Pebble Beach in 2016. In 2018, GM revealed its dramatically named DOHC twin-turbo V8. Considering what came before, the Blackwing clearly wasn't designed for cars. It was designed for world domination. However, against the backdrop of plummeting sedan sales, the CT6 didn't sell like GM had hoped. The automaker hesitated to marshal another fleet of Brinks trucks to fund entries into a cratering bodystyle. Removing sedans from the world domination equation created more difficult math for the crossovers and the Escala.

Cadillac Super Cruise gets system enhancements, more compatible highways

Cadillac is updating Super Cruise to make it available to use on more highways, and it will offer better performance, too. Previously, Super Cruise worked on about 130,000 miles of highways across the continent. This update expands that to 200,000 miles. That's because GM has mapped that many more miles to be compatible with its lidar mapping system. As for the performance update, Cadillac says there will be enhancements to the driver monitoring system. That's the key feature that separates Super Cruise from all the other systems out there, making it a truly hands-free experience. It's able to quickly tell whether your eyes are on the road, and it reacts accordingly. We asked for details about the improvements, but all Cadillac would tell us is that there are "slight refinements to the driver attention system to even more accurately detect driver attention." Perhaps it's related to reports of sun-related issues plaguing the infrared monitoring camera. We can't tell you for sure. As for the extra miles, Cadillac says some added highways now include limited intersections and traffic control devices. Basically, there may be a stoplight or some cross traffic thrown into the mix now. Since GM has actually gone and mapped these areas, the car will tell you to take back control when approaching a railroad crossing, pedestrian crossing, stoplight or stop sign. Cadillac included a map (above) depicting the original and new Super Cruise compatible highways. You'll notice there are a lot more highways in the midwest and southeast, in addition to almost being able to cross the entirety of Canada now. Things are still a bit sparse in the western part of the country, but there aren't as many highways out there anyway. Owners of 2018 and 2019 Cadillac CT6s can expect to get the upgrade, but it's not as easy as you may think. Folks will have to take their CT6 in to the Cadillac dealer, where the "system enhancement" will take place. However, that enhancement doesn't include the additional miles. Cadillac says that update will be sent out over-the-air throughout the summer and fall. Updates for Super Cruise seem to be coming out with regularity. Last year Cadillac updated the system for easier activation, better lane placement (for passing large vehicles) and added gauge cluster messages for more information. We happen to love using the technology here at Autoblog, and gave it our 2019 Technology of the Year award.

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.
