2016 Cadillac CT6 to get an aluminum body?

Well this is interesting: A hot-off-the-press report in Automobile claims the coming Cadillac CT6 will have an aluminum body. Most write-ups on the CT6 claim it will have a body that's a combination of aluminum and high-strength steel - Automobile itself wrote of "high-strength steel, aluminum, and steel stampings" in October. An all-aluminum body would be quite the reversal, contradicting the last four months of reportage and company statements on the matter. Mark Reuss, EVP of global development at General Motors, told The Detroit News in October, "We will create with the CT6, the world's most advanced body structure... [and] it's not aluminum. It's a stronger, smarter, safer premium luxury vehicle." It echoed the earlier Automobile story in saying the CT6 would use GM's "patented welding technology with high-strength steel, aluminum and steel stampings and castings." That same month, the Wall Street Journal ran a piece titled, "GM Won't Follow Aluminum Strategy in Future Cars," in which Reuss said, "making big statements around all carbon fiber, all aluminum, all magnesium, they're very interesting," and that GM wouldn't be doing it. That piece also circled back to a material mix and GM's special welding process, saying the CT6 "will have a body made of aluminum, high-strength steel and other materials, and will be 100 kilograms (220 pounds) lighter than a similar-sized car made of high-strength steel." We don't know what kind of body Cadillac's new assault on luxury is going to wear, but now we can't wait to find out.

2017 Cadillac CTS-V Drivers' Notes | V is for velocity

The 2017 Cadillac CTS-V is as close to a four-door Corvette Z06 as you're ever likely to get. Underneath the carbon-fiber hood rests one hell of an engine, a 640-horsepower supercharged V8. It's only slightly less powerful than what you'll find in the Corvette. Thanks to GM's chassis wizards, the car's handling is an equal match for the powerful engine. This particular car packs in a number of options, including Recaro seats and the performance data recorder that allows owners to measure lap times and record video. The most expensive option is the $6,950 Carbon Black Package. This nets you a carbon fiber hood vent, front splitter, spoiler and rear diffuser. This car isn't cheap, but it does undercut the less powerful Audi RS7 and Mercedes-AMG E63 S. Associate Editor Joel Stocksdale: This is a seriously fun, if also flawed, car. And the biggest contributor to the fun is the big lump of V8 under the hood. The supercharged 6.2-liter makes 640 horsepower, but Cadillac could've left the number off and just called it "effortless." The gentlest pressure on the gas pedal will result in you picking up an extra 10 mph without ever noticing. And when you stomp on it, you get this huge and immediate surge of acceleration. It's truly giggle-inducing. Although the CTS-V is big and heavy, it handles the power well. It gives you enough info on what's happening so you feel in control, and the chassis is impressively composed. The only real weak points I can find on the CTS-V (besides the low gas mileage) are the interior controls. They are abysmal. The infotainment screen is pretty poor, with a clutter of information at the main screen, and difficult-to-find commands for getting to other menus. But worse than that are the climate and volume buttons. They're all touch-sensitive spots on the center stack. They're not very responsive, and the vibratory feedback it provides isn't noticeable while driving. It doesn't help that the feedback feels pretty inconsistent, too. For me, I think I could learn to live with the infotainment, simply because I love the way the rest of the car feels and drives. But, Cadillac, you need to get to updating this ASAP. Associate Editor Reese Counts: OK, Cadillac's infotainment system sucks. Let's get that out of the way. Touch capacitive interfaces don't work well in cars. This does have the old version of CUE, so I'm hoping the next-gen system will fix some of the interface issues. Like Joel, this wouldn't turn me off from buying the car.

Cadillac's 4.2-liter Blackwing V8 to die with the CT6?

Cadillac's 4.2-liter twin-turbo Blackwing V8 debuted only last year, popping up in the CT6 V-Sport — now the CT6-V — with 550 horsepower and 627 pound-feet of torque. The engine's been stymied in every attempt to power a different Cadillac model since then. Its only two use cases have been a first and second run of the original, limited-edition super sedan and the CT6 Platinum V8 trim at a slightly detuned 500 hp and 553 lb-ft. Motor Trend cites "a highly placed source at GM" as saying that the Blackwing won't go into the coming high-performance version of the CT5-V nor in the next-gen Escalade. Left without options, there's a chance the Blackwing will die with the CT6, itself a sedan with its grille on the executioner's block just waiting for the bite of an ax that might or might not shortly fall. Cost-cutting has been tagged as the reason for this misfortune; Cadillac's sales malaise and lack of clarity as to how to turn sales around led GM to downsize the brand's allowance. The parent company chose to build the new CT5 on the Alpha platform used for the erstwhile ATS and CTS instead of the Omega platform underpinning the CT6. Along with that choice, the MT report says expense reasons nixed fitting the Blacking V8. We know the lower-tier V series CT5 will work with a twin-turbo 3.0-liter V6 making 355 hp and 400 lb-ft. When we heard spy video of the upper-tier V series CT5 out testing, the engine sounded like the 6.2-liter supercharged V8 that would be a carryover from the last model.  The XT6, also rumored to get some V sauce, simply can't fit the V8. Instead of sitting on the Omega platform as once planned, the XT6 rides on the C1XX architecture under other GM products like the Buick Enclave and Chevrolet Traverse. The C1XX engine bay doesn't have room for a stouter V6, much less a hi-po V8. The next-gen Escalade ruled itself out due to price issues in back, not in front. MT writes that the independent rear suspension supporting GM's next-gen full-sized SUV quartet has burned through cash in development, putting engineers a few direct deposits short of the funds needed to massage Blackwing installation. Earlier this year at least one report said the twin-turbo DOHC V8 could serve the top-spec next-gen Escalade. More recent reports of a performance-heavy next-gen Escalade have predicted the 6.2-liter supercharged LT4 V8 from the Chevrolet Camaro ZL1 and Corvette Z06.
