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.

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.

2015 Cadillac Escalade

Cadillac has been an interesting story in the auto industry over the past several years. Its comeback bid may be well over a decade old, but it's only recently that the Wreath and Crest has transformed from the auto industry's retirement home into its hot new thing. Today's Cadillac is a powerful marque working to instill passionate design, sound driving dynamics and cutting-edge technology into each model it builds, with vehicles like the ATS and redesigned CTS leading the charge.
Now, its latest model has arrived. This fourth-generation Escalade is among the most important new Cadillacs since the division's renaissance kicked into high gear. It's the brand's de facto flagship, and the first vehicle many young people think of when hearing the name "Cadillac." In the past, the Escalade was the chosen vehicle of the rich, flashy and famous. It's suffered over the past few years, though, particularly as new and more luxurious competitors have come to the fore.
With this latest redesign, General Motors is aiming to retake the spotlight as purveyors of the market's premier luxury SUV. To find out if it's been successful, I ventured down to the South Carolina Lowcountry to test the all-new 2015 Escalade.
