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.

U.S. new-vehicle sales in 2018 rise slightly to 17.27 million [UPDATE]

DETROIT — Sales of new vehicles in the U.S. rose slightly in 2018, defying predictions and highlighting a strong economy. Automakers reported an increase of 0.3 percent over a year ago to 17.27 million vehicles. The increase came despite rising interest rates, a volatile stock market, and rising car and truck prices that pushed some buyers out of the new-vehicle market. Industry analysts and automakers said strong economic fundamentals pushed up sales and should keep them near historic highs in 2019. "Economic conditions in the U.S. are favorable and should continue to be supportive of vehicle sales at or around their current run rate," Ford Chief Economist Emily Kolinski Morris said after the company and other automakers announced their sales numbers Thursday. That auto sales remain near the 2016 record of 17.55 million is a testimonial to the strength of the economy, said Mark Zandi, chief economist at Moody's Analytics. The job market, he said, has created new employment, and wage growth has accelerated. "That's fundamental to selling anything," he said. "If there are lots of jobs and people are getting bigger paychecks, they will buy more." The unemployment rate is 3.7 percent, a 49-year low. The economy is thought to have grown close to 3 percent last year, its best performance in more than a decade. Consumers, the main driver of the economy, are spending freely. The Federal Reserve raised its key interest rate four times in 2018 but is only expected to raise it twice this year. Auto sales also were helped by low gasoline prices and rising home values, Zandi said. It all means that people are likely to keep buying new vehicles this year even as they grow more expensive. The Edmunds.com auto-pricing site estimates that the average new vehicle price hit a record $35,957 in December, about 2 percent higher than the previous year. It will be harder for automakers to keep the sales pace above 17 million because they have been enticing buyers for several years now with low-interest financing and other incentives, Zandi said. He predicts more deals in the coming year as job growth slows and credit tightens for higher-risk buyers. Edmunds, which provides content, including automotive tips and reviews, for distribution by The Associated Press, predicts that sales will drop this year to 16.9 million.

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.
