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 considering new powertrain options for large SUVs

Aside from the new General Motors offerings, there's not a whole lot of action going on in the fullsize SUV segment. That doesn't seem to be stopping GM from pushing the envelope in the market as Automotive News is reporting that the automaker is looking to introduce some new powertrain options into the Chevy Tahoe (and Suburban), GMC Yukon (and Yukon XL) and the Cadillac Escalade - all have been redesigned for the 2015 model year.
Now, we already know that GM and Ford are collaborating on nine- and ten-speed transmissions for a broad range of applications (including the big SUVs), but this new report says that GM is also considering other options as a way to one-up the competition and, of course, to optimize fuel economy. AN quotes Jeff Luke, executive chief engineer for GM trucks, as saying that "interesting powertrain technologies" are coming including a return of a hybrid SUV and possibly even a diesel engine. Although it sounds like the latter could come down to how customers respond to the 2014 Jeep Grand Cherokee EcoDiesel.

2016 Cadillac ATS-V brandishes 450 horses and 6-speed manual

Details about the hotly anticipated 2016 Cadillac ATS-V are tumbling out, and they look to be everything we could ask for in a high-performance Caddy coupe.
According to Road & Track, the ATS-V will use a version of the twin-turbocharged 3.6-liter V6 from the CTS Vsport, but the wick will be turned up to 450 horsepower and 445 pound-feet of torque. In glorious news for driving enthusiasts everywhere, that potent mill will be available with either a six-speed manual or eight-speed automatic.
According to R&T, the engine has a heap of high-performance tech to let it make the extra ponies, including titanium connecting rods, two water-to-air intercoolers, titanium turbines for the turbos and an additional radiator dedicated to cooling the gearbox and electronically locking differential. Keeping it all planted are a set of Michelin Pilot Super Sport tires, and a suspension with 50 percent more roll stiffness.
