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 introducing V2V communications on 2017 CTS sedans

While Audi has introduced vehicle-to-infrastructure technology in select cars in select cities, Cadillac is focusing on vehicle-to-vehicle (V2V) communications, and it all starts with the CTS sedan. Starting this month, the company will be adding V2V equipment to 2017 models. The feature will be standard on cars in the US and Canada. These V2V devices will allow these new Cadillacs to communicate with each other up to 980 feet away. The cars will be able to transmit and receive information on speed, direction, and location. An example of how this data can be used is in detecting a car coming up a side street that could pose a possible collision risk. The cars will also be able to transmit data about brake use, hazard lights, and low traction situations for advance warning of hazards. The warnings can be displayed on the instrument panel and heads-up display. Currently, the system only communicates with other CTS sedans equipped with the technology. According to Chris Bonelli at Cadillac part of the reason is that the CTS will be the only car with the equipment on US roads at the moment, but it also isn't currently set to communicate with other cars if they were to be offered right away. However, he said that the company is absolutely willing to work with other companies to make the system compatible if or when other cars are offered with the technology. This V2V system also doesn't send data to any sort of network, instead only communicating with nearby cars. For the time being, this precludes the possibility of receiving road condition information from cars that are farther away. But as Cadillac points out, it should work under any conditions with no delay since it isn't dependent on information from a network. As far as security is concerned, Bonelli told us that the Cadillac system does have firewalls and other security measures to keep it protected from interference. He also said the cars don't store any data they receive. In addition, none of the data could be used to identify a particular person. The cars use a radio frequency set aside by the government for this use. The introduction of this technology also puts Cadillac well ahead of proposed legislation by the Department of Transportation. The organization wants this type of short-range V2V communications equipment to be a standard feature by 2023, believing the technology could prevent many injuries and deaths due to crashes.

GM recalling 117,000 sedans, crossovers, SUVs, pickups and vans

General Motors has issued a stop-sale to dealers and has notified the National Highway Transportation Safety Administration of its intention to recall 117,000 vehicles in the United States, Canada and Mexico. Of those vehicles, only 4,500 are at dealerships.
The affected vehicles include the Cadillac CTS and Chevrolet Impala sedans, fullsize SUVs (Cadillac Escalade, Chevy Tahoe and Suburban and GMC Yukon and Yukon XL), Lambda-platform crossovers (Chevy Traverse, Buick Enclave and GMC Acadia), heavy-duty pickups (Chevy Silverado HD and GMC Sierra HD) and fullsize vans (Chevy Express and GMC Savana). The sedans and body-on-frame SUVs include model years 2013 and 2014, while the CUVs, heavy-duty pickups and vans are limited to MY2014.
GM confirmed the recall to Autoblog via an emailed statement (which we've included below). According to the statement, the issue at hand in what is the company's 69th recall of 2014 covers the chassis-control module. Automotive News is reporting that a problem in the chassis-control system could cause a short in the module, which could cause the engine to stall or fail to start. The fault could also affect the trailer-brake control, provided it's equipped.
