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.

Here's what else you could buy for the average new-car price of $40,573

Autoblog may receive a share from purchases made via links on this page. Pricing and availability are subject to change. The average price of a new car in America hit a new record in December 2020: $40,573. Not that we're surprised — the average has been over $35,000 for the past few years — but seeing that baseline figure crest 40 large is still a sticker-shock to the system. So, as we do every once in a while, we put our collective heads together and came up with a list of alternatives that you could choose to buy for that sum, new or old, classic or practical. Now, let's be crystal clear about one thing here. We're not actually recommending you make this type of decision. That said, we wouldn't blame you if you did. Managing Editor Greg Rasa: $40,000 will buy a fully loaded Camry or moderately equipped crossover. Or, for $39,997, to be exact, one could go motoring in a fine British automobile. This 2006 Aston Martin DB9 Volante in Alabama has 21,452 miles on it, and depreciation has worked its cruel magic: It is listed for less than one-quarter of its $168,000 starting MSRP when it was new. A check of other used DB9s nationwide indicates this is a fair price. This Aston's CarFax reveals two owners. (One, really, as the second was a dealership. Looks like it got traded in for a Porsche.) If you're understandably concerned about reliability, its service history indicates no surprises to date. Remember, it has a 450-horsepower 5.9-liter V12. And spring is coming. Of course a used Aston Martin is riskier than a new Camry. But as Louis Prima sang, "Enjoy yourself, it's later than you think." What price beauty? Less than $40 grand. Associate Editor Byron Hurd: This price point opens up a ton of options in the "nearly new" luxury space, including a few good enthusiast picks, but my nod here goes to the Cadillac ATS-V. The discontinued, M3/M4-rivaling, 465-horsepower sport sedan and coupe can be had all day long in this price range with low miles. In fact, the real challenge is finding one in the spec you want, since it's one of those old-fashioned cars that actually presented the buyer with choices. Here's a clean, six-speed sedan in an actual color for less than our target price, for example. Coupes are more plentiful than sedans, especially in interesting colors, but there are plenty of them out there.

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:
