New V6 engines are only the start at Cadillac

Cadillac debuted its new family of V6 engines Friday, but that's not all General Motors' luxury brand has in store for the coming years. The six-cylinder powerplants will certainly help Cadillac in the near term, but they're just two of the many parts of the company's future strategy. GM has invested $12 billion in Cadillac to help the brand grow over the next five years, and the company will launch eight new products between now and 2020. That all starts with the launch of the CT6 flagship later this year – a fullsize luxury sedan we'll see for the first time in New York on March 31. The CT6 will introduce several new features and technologies to the Cadillac range, and with its launch also begins the slow restructuring of Cadillac's model-naming system. The new nomenclature means CT and XT badges for cars and utilities, respectively. Cadillac says that of the eight new vehicles it plans to launch by 2020, five of them will be first-time offerings in market segments where the brand currently does not play. But it's not just about new products – new powertrains are an important part of the Cadillac story, too. After the new V6 engines – a naturally aspirated 3.6-liter and a twin-turbocharged 3.0-liter engine – launch later this year in the 2016 ATS, CTS and CT6, the company says it has a strategy for V8 power – possibly a twin-turbo application – as well as future electrification. Cadillac also says it's working on adding four- and six-cylinder diesel powertrains, though it's unclear which vehicles will make use of those engines. This new six-cylinder engine family is indeed important, with Cadillac's chief engineer, David Leone, calling it the "most advanced V6 in the industry." With 335 horsepower, the 3.6-liter engine is the highest output, naturally aspirated V6 powerplant Cadillac has done – and that's SAE-certified, and on regular fuel. Beyond that, the 3.0-liter mill (pictured at right) marks the first application of GM's active fuel management system on a twin-turbocharged engine. This means that when full power isn't necessary, the TTV6 can run as a 2.0-liter V4 in order to save fuel. New transmissions are also part of the V6 engine story. GM's all-new eight-speed Hydra-Matic 8L45 gearbox will be paired to the 3.6-liter V6, and the 3.0-liter TTV6 will use the company's existing 8L90 transmission that is already found in the Chevrolet Silverado and GMC Sierra pickups (with the 6.2-liter engine).

GM recalls select Tahoes, Yukons, Escalades for rear driveshaft issue

GM is recalling a number of its full-size SUVs due to an issue with the rear driveshaft assembly that could ultimately result in driveshaft failure. The actual number of total vehicles involved in the recall is small at just 1,789, but it’s spread out across the entire 2021 model year full-size GM vehicle lineup. That means a small number of every model is being recalled, including the Chevrolet Tahoe, Suburban, GMC Yukon, Yukon XL and the Cadillac Escalade and Escalade ESV. GM traced the issue back to certain driveshaft assemblies with ball bearings that were not properly heat treated. If theyÂ’re not properly heat treated, GM says that the balls may deform over time, causing noise and vibration. Continue to drive in this condition, and GM says the affected joint in the driveshaft assembly could seize, causing loss of drive power. However, the problem wonÂ’t present itself all at once, as GM says there will be a gradual increase of noises and vibrations before total failure. For those few owners with affected vehicles, GM says that it will replace the left and right rear driveshaft assemblies with properly-built units. Per usual with recalls, this will be done at your local dealership at no cost to the owner. If you have one of the recalled SUVs, expect to be notified mid-March. Related video:

Will attaching the electrodes re-animate Cadillac?

This announcement last week from General Motors —"Cadillac will be GM's lead electric vehicle brand"— followed quickly by the surprise reveal Sunday night of a Cadillac EV crossover, leads one to wonder whether this is a case of GM pulling out the defibrillator and hoping a full-on jolt of electricity will revive Cadillac from its ongoing diminution in the market. In 2018, Cadillac U.S. sales were 154,702 vehicles, which was down from the 156,440 it had sold in 2017. And the 2017 sales were down significantly from the 170,006 vehicles delivered by Cadillac in 2016. And that is down from the 175,267 sales of 2015. Sure, part of Cadillac's problem — one shared by some other OEMs — is that its sedans aren't selling. But if we put those to the side, realize that in 2018 sales of the venerable Escalade were down by 2.2 percent. Admittedly, that rig is a little old in the grille, and it's suddenly gotten strong competition from the Lincoln Navigator, so a sales decline isn't too surprising. But the XT5, the compact lux vehicle that was launched in 2016 as a model-year 2017 product, had an 11.3 percent decline in a segment that is doing nothing but growing. This is not promising. Although the argument at GM HQ might be that Cadillac can reinvent itself as a Tesla fighter, one of the things that isn't often noted about Tesla vis-a-vis other OEMs is that while sedan sales are generally down, Tesla, which had an estimated 2018 sales volume of 197,680 (according to Cleantechnica.com), made its numbers primarily with the Model 3 and Model S, both sedans, as it has just the Model X crossover. So it isn't just about vehicle architecture. It is going to take more than an electric SUV to change Cadillac's performance. But here's where circumstances can fall in Cadillac's favor. Scale can be highly beneficial to Cadillac versus Tesla. The Chinese market, even though it is weakening of late, will be largely predicated on "New Energy Vehicles," which means electrified and fully electric. And while Tesla only just now broke ground on a factory in China, LMC Automotive reports that as of December 2018, SAIC GM is already well-established there and is the third-largest vehicle manufacturer in China (behind SAIC Volkswagen and FAW Volkswagen). Cadillac is going to be able to take advantage of GM's global efforts in developing EVs, so soon the Cadillac showroom could be filled with an array of luxury EVs that may make even Tesla loyalists take another look.
