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).

2022 Cadillac CT5-V Blackwing will get carbon fiber seat backs

Cadillac is putting the finishing touches on the 2022 CT5-V Blackwing, the high-performance sedan that will pick up where the CTS-V left off. It announced the model will be available with carbon fiber front seat backs. Presumably found on the list of extra-cost options, the weight-saving carbon fiber seat backs will stand out with a book-matched design and a laser-etched V-Series logo that will remind the passengers sitting in the back that they're not riding in a regular CT5-V. Interestingly, Cadillac noted the seats will also boast "other customer-centric innovations and features" that will be detailed closer to the sedan's on-sale date. Chairs are hardly on the front lines of automotive innovation, so we're looking forward to learning more about what Cadillac has in store. Drivers will have carbon fiber in front of them, too, because the multi-function steering wheel's bottom spokes will be made with the composite material. Cadillac hinted the sedan's top speed will lie in the vicinity of 200 mph. 2021 Cadillac CT5-V Blackwing spied View 15 Photos Nearly everything else we know about the CT5-V Blackwing comes from a diverse selection of rumors, industry murmurings, and spy shots. We learned earlier in 2020 that it might receive an updated version of the 6.2-liter V8 that powered its predecessor, not the 4.2-liter Blackwing engine it's named after, and leaked images strongly suggest a manual transmission will be available, though we assume Cadillac will also offer an automatic. It might be a six-speed stick, or Cadillac could use a version of the Chevrolet Corvette's seven-speed manual. Our questions will be answered when the 2022 Cadillac CT5-V Blackwing finally makes its debut. It's scheduled to go on sale in the summer of 2021, so its unveiling is likely a couple of weeks away, and Cadillac warned availability will be limited. The smaller CT4 which replaced the ATS, is also in line to get the Blackwing treatment.

Roll pins in recalled 2014-2015 Cadillac CTS V-Sports could crack

General Motors has issued a recall for select 2014-2015 Cadillac CTS V-Sport sedans due to roll pins in the rear differential that could crack. The recall only affects 2,866 vehicles, but it is expected that 100% of those vehicles have the defective parts. According to NHTSA Campaign No. 20V038000, 2014-2015 CTS V-Sports built between July 1, 2013 and May 15, 2015 have roll pins in the rear-axle differential that could "fatigue" and "fracture." If these pins were to break while the vehicle is in motion, it could cause the rear to lock up, which might create a potentially dangerous driving situation. In September 2019, a GM engineer noticed a forum discussion about the problem with the V-Sports, which can be easily identified by their twin-turbo 3.6-liter V6 engines. Because he had dealt with similar issues with his own personal vehicle, he submitted a report, and an investigation was opened the next month. To make good with its customers, GM has promised to replace the rear differentials on all affected vehicles. The recall report says the roll pins in the replacement parts will have "increased strength" and a double-shear design rather than the original single-shear design.  GM plans to send customers recall identification notices starting March 9, 2020.
