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).

Beast mode on the open road: New presidential limo close to delivery

Signs of the Beast have been seen on the open roads around Milford, Mich., home of GM's Proving Grounds. The Beast, in this case, being the nickname for the next-generation presidential limousine. We've seen this car previously in spy shots while parked or driven, going back to January 2016. This is our spy photographers' latest look at the vehicle, and the first on public roads. Which may be a sign that it is almost ready for delivery. It replaces the current Beast, which has been in use since 2009. And "car" isn't exactly the right word for this rig, as it's actually a unique vehicle with Cadillac styling cues custom-built atop a medium-duty truck frame. There may possibly be more than one Beast 2.0 delivered, because two limos are sent anywhere the president goes, to provide a backup or decoy. The grille has touches of the Cadillac Escala concept car, which is heavily influencing Cadillac's evolving future look. But it's what's inside that intrigues everyone. Here's what we know, or at least has long been rumored, about the current Beast and the new Beast 2.0. 1. It has its own airplane. It and its twin follow the president around the globe aboard a C-17 Globemaster cargo plane. 2. It's heavily armored, with 5-inch-thick glass, 8-inch-thick doors that weigh as much as a commercial aircraft door, and its components include titanium, ceramics, and a bombproof plate that covers the underside. As such, the old Beast was estimated to weigh between 14,000 and 20,000 pounds. You can therefore imagine how it got its name. 3. It's equipped like the Batmobile or the Green Hornet's Chrysler Imperial Crown, with run-flat tires and night-vision gear. It can fire gas canisters out the front bumper. 4. It has a diesel engine because of its weight and size (see the gallery below for a sense of scale). And of course, diesel is less flammable in a firefight. The old Beast supposedly gets 8 mpg. 5. Its Secret Service codename is Stagecoach. 6. There's a shotgun by the driver and God-knows-what in the trunk. 7. It supposedly has a stock of blood in the president's type, along with a defibrillator and other emergency gear. 8. And it's pretty nice inside, by all accounts. Since this is not Trump's own personal vehicle and may well serve his successor, let's assume the gold leaf has been kept to a minimum and it's done up in tasteful leather and wood. But then again, who really knows, outside of the Secret Service and a handful of GM engineers.
