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 ATS to go racing in 2015 as CTS.V.R replacement

Cadillac has been racking up victories with the CTS.V.R in Pirelli World Challenge racing for two model generations now, including recent GT class championships in 2012 and 2013. However, even winning racers eventually have to retire, and it looks like the CTS may be taking a bow at the end of the season. In its place, Caddy is reportedly working on a new racecar based on the ATS Coupe, and it might even get to compete internationally.
According to Racer, Pratt & Miller Engineering is leading the development and is already lapping the ATS racecar in Michigan for testing. It reportedly drops the CTS' V8 in favor of a twin-turbocharged V6 powering the rear wheels. Since this is the same team behind the hugely successful Corvette Racing program and the current CTS.V.R, the latest car appears to be in good hands.
The new model would also adhere to GT3 rules, according to Racer, and that might signal a big change for Cadillac's motorsports program. It means that the ATS could be sold to teams in the numerous series around the world that accept these vehicles. That would broaden the luxury coupe's exposure and put it up against GT3 racecars from premium brands, like Bentley, Porsche and McLaren. If it wins, the change could be a marketing bonanza for the brand.

Cadillac back on track with 600-hp ATS-V.R racer in FIA GT3 spec [w/video]

There was already a rumor brewing that Cadillac might eschew the CTS as its racecar next season in favor of the ATS Coupe. It turns out that is absolutely the case, and now we know just what this 600-horsepower, future racer looks like. The coupe might not be limited to competing in just the US, though, because it's built to FIA GT3-specifications, meaning that this Caddy is also eligible to race in over 30 series worldwide against the likes of Bentley, McLaren, Audi and other premium brands.
The heart of this massively winged Cadillac is an engine dubbed the LF4.R. It's based around the unit in the production ATS-V and CTS Vsport but with larger turbos, bigger intercoolers, side exhausts and other tricks. Cadillac claims it makes a monstrous 600 hp and 520 pound-feet of torque in unrestricted form.
As the photo above shows, the ATS-V.R also wears an aggressive aero kit with a carbon fiber front splitter, and a wing at the back that could probably double as a picnic table in a pinch. The dry weight of the whole package is quoted at about 2,900 pounds, which is around 700 pounds less than the street version.
