Autoweek divulges details on Presidential limo

Ever since the latest presidential limousine, also known as The Beast, debuted in 2009, we've wondered what's underneath that black Cadillac body. We already know a few details, like the fact it isn't a Cadillac at all, but a very heavy duty truck chassis from General Motors with a body that resembles a super-sized Caddy. Autoweek, however, has managed to extract new details from veteran Secret Service agents about the closely guarded presidential limo. Their methods, of course, are classified.
Designed to be a rolling office, bunker and escape pod all in one, the current presidential limo is far different from previous presidential state cars, which were heavily modified production vehicles. As we would expect, The Beast uses thick, military-grade body armor (eight inches on the doors), an armored fuel tank, special run-flat tires with Kevlar lining, an encrypted satellite phone, a fully sealed cabin with its own oxygen supply and a trunk full of weapons and medical equipment that includes a supply of the President's blood type (in case the car gets cut off from the ambulance that's always present in the President's motorcade).
The Beast also comes with a Halon fire-suppression system, night vision and is powered by a V8 engine, which we already knew runs on gas and not diesel, that returns an EPA-unfriendly estimated 3.7 miles per gallon. The Secret Service operates a fleet of 12 limos and each Beast costs $1.5 million. Lastly, AW estimates that the 18-foot-long state car weighs 15,000 pounds, and each Secret Service agent that drives the car must be specially trained to maneuver such a massive vehicle.

Cadillac president de Nysschen says electrification coming 'across the spectrum'

We like to pick on new Cadillac president Johan de Nysschen for his insistence, many years ago, when he was president of Audi of America, that plug-in vehicles are for idiots. Listening to him give the keynote address at the Washington Auto Show today, you wouldn't know he ever said anything negative about an electric vehicle. Instead, he sounds something like a EV-angelist. De Nysschen said that Cadillac will be able to benefit from GM's considerable expertise in plug-in technology, which he said would be "applied across the spectrum of our portfolio." GM's electric committment will help in "making electrification commonplace." With the plug-in ELR already on the road, de Nysschen said that the company's next step in advancing powertrains will be the introduction of stop/start technology – which de Nysschen called an "important system to reduce fuel consumption and CO2 emissions" – into a Cadillac for the first time later this year. Without giving any specific details, de Nysschen said that Cadillac will introduce eight new models (not necessarily plug-ins) by the end of this decade, including five that "will take Cadillac into market segments where the brand is not even present today." These new vehicles will likely be much lighter than today's vehicles, de Nysschen said, because "weight reduction today is critical to automotive design, it helps to improve fuel efficiency and contributes to desireable vehicle dynamics." The key is to reduce weight without compromising safety or comfort and to use the right material – steel, aluminum, carbon fiber – in the right place at the right time. It was a not-so-subtle jab at Ford and its new aluminum F-150. "In the pursuit of weight reduction, some manufacturers have also opted for abandoning steel and have gone for an all-aluminum approach," he said. "At Cadillac, we believe that different materials each present particular advantages in specific applications. There is no single material that represents the optimum balance of the conflicting objectives of every single application." Related video:

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).
