Cadillac CT6 beefs up with 400-hp twin-turbo V6

Cadillac's engine lineup is set to get a makeover led by the potent powerplants under the hood of the CT6. Our man Steven Ewing is onsite at an event in Detroit reporting all the details. Here's what we know so far: The CT6's top engine will be a 3.0-liter twin-turbo V6. It's the first twin-turbo with cylinder deactivation, which essentially makes the V6 able to convert to a V4 unit. Power will be 400 horsepower at 5,500 rpm and 400 pound-feet of torque at just 2,500 rpm. No word on what a potential CT6-V would get. The CT6 will also have a naturally aspirated V6 that Cadillac is claiming to be all-new. It's rated at 335 hp at 6,800 rpm and 284 lb-ft at 5,300 rpm. That's an improvement of 14 hp and nine lb-ft compared with today's 3.6-liter V6, and fuel economy increases nine percent. Cadillac says it's the highest output for a naturally aspirated V6 that's SAE-certified and runs on regular fuel. Both of these V6s will have stop/start technology and will be paired to with eight-speed automatic transmissions. The 3.6-liter V6 will also be used in the 2016 CTS and the 2016 ATS. Meanwhile, Ewing reports that Cadillac says the ATS-V is actually more powerful than initially announced, though there are no numbers to flesh that claim out as yet. The brand also plans to offer four- and six-cylinder diesel engines in various vehicles and new V8 options. The CT6 bows at the New York Auto Show. It will use an aluminum-intensive body that reduces weight by 198 pounds compared with a steel setup and continues Cadillac's creased design language used on the CTS and ATS models. The CT6 goes into production late this year in Detroit.

Cadillac won't replace XTS after 2019

Cadillac wouldn't be Cadillac without a large sedan, but the definition of just which model fits that bill changed last week. Before the New York Auto Show, that role fell to the XTS. After the New York Auto Show, though, the focus shifted to the CT6. So what's to become of the XTS now that the CT6 has emerged? According to the latest intel, it'll live out the rest of its lifecycle until around 2019, but then drive off to its own funeral like so many limousines and hearses that were built off its platform. This was learned based on comments made by Cadillac chief Johan de Nysschen at the closed-door unveiling of the CT6 in Manhattan: "Ultimately, a car like XTS when it reaches the end of its lifecycle, will not be replaced." That'll be bad news for the livery business that – in the post-Town Car era – has come to rely on the XTS as the basis for its stretch jobs. "We will not have a car that will lend itself to these kind of modifications and we will probably withdraw from those markets," de Nysschen told GM Inside News. That's not all the new Cadillac boss had to say, though: he also indicated that the replacements for the ATS and CTS will be positioned differently from the current models: "As we move into the future refining our sedan portfolio, there will be no direct successor to the CTS. There will be no direct successor to the ATS. There is no point to renaming those cars because in the future those cars will disappear." Based on Johan's comments and those we've heard until now, we'd expect the replacement for the ATS to move down a size to take on the likes of the Audi A3 and Mercedes CLA, and the CTS' successor to move down half a size class as well to give the new CT6 a bit more breathing room, and possibly an even larger flagship sedan to be positioned above them all.

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.
