Cadillac CT6 uses aluminum to save 200 pounds

In Cadillac's recently launched ad campaign, the luxury brand's tagline is "Dare Greatly," and the two words suggest a brand willing to take big swings, even if they don't always connect. From what the company is promising, the forthcoming CT6 seems like an embodiment of that new motto. With an eventual range of turbocharged engines, reportedly including a turbo V8, a possible plug-in hybrid and streaming rearview mirror, the sedan is certainly pitched as tech showcase. Of course, extensive use of aluminum is practically mandatory to play in the luxury field these days, and Caddy is proving its latest creation can do that too. Despite the weighty appearance of the sedan's squared-off exterior, 64 percent of the CT6 is aluminum, including the entire exterior. Caddy claims that using so much of the lightweight metal sheds 198 pounds off the scales compared to using conventional steel. There still is some steel in the CT6; although it's predominately the high-strength variety. The engineers use the heavier metal for portions around the cabin and B-pillar for added safety. Cadillac also claims using steel "close-out panels" on lower portions of the sedan make the cabin quieter without needing as much sound deadening. The buildup to the CT6's public unveiling has been a long time coming after Cadillac pinned the flagship (for now) sedan's debut at the New York Auto Show nearly a year ago. When the sheet finally comes off on March 31, we get the first good idea about just how great Caddy's latest act of daring really is. Cadillac CT6 Elevates the Science of Mass Efficiency 2015-03-13 Technology DETROIT – Cadillac will use an advanced mixed-material approach for the lightweight body structure of the upcoming CT6 range-topping sedan. The structure is aluminum intensive, but the new Cadillac also includes 13 different materials customized for each area of the car to simultaneously advance driving dynamics, fuel economy and cabin quietness. The CT6 will debut March 31 at the New York International Auto Show and go into production late this year at General Motors' Detroit-Hamtramck assembly plant. "This is the rocket science of automobile construction and manufacturing today," said Cadillac President Johan de Nysschen.

The biggest gas-guzzlers of 2024: 'The Meanest List' is the opposite of greenest cars

In some circles — especially some automotive circles — bigger is better. This explains the Hummer, for example. In its so-called “Meanest List” of a dozen models, the American Council for an Energy-Efficient Economy (ACEEE) makes no apologies for berating “the worst-performing mass market automobiles” sold in 2024 in the U.S. The most diminutive car on the list is a Chevy Corvette Z06. At the top of this particular heap is the Mercedes-Benz AMG G63, a gas-powered SUV that the environmental agency says was “the worst-performing vehicle of the more than 1,200 models assessed by Greener Cars and has an annual fuel cost over $4,000.” Not to mention its MSRP of around $184,000. Rank Make & Model Powertrain Green Score MSRP Estimated Annual Fuel Cost* 1 Mercedes-Benz AMG G63 Gas 20 $184,000 $4,242 2 Ram 1500 TRX 4x4 Gas 22 $98,335 $3,819 3 Ford F150 Raptor R Gas 24 $79,975 $3,777 4 Cadillac Escalade V Gas 26 $152,295 $3,388 5 Dodge Durango SRT Gas 26 $74,995 $3,332 6 Jeep Wrangler 4dr 4X4 Gas 27 $35,895 $3,260 7 Jeep Grand Wagoneer 4x4 Gas 28 $91,945 $3,058 8 Mercedes-Benz G550 Gas 28 $143,000 $3,186 9 GMC Hummer EV SUV EV 29 $98,845 $1,746 10 GMC Sierra Gas 29 $37,700 $3,069 11 Chevrolet Corvette Z06 Gas 30 $114,395 $3,169 12 Mercedes-Benz Maybach S680 Gas 30 $234,300 $3,031 *ACEEE analysis using EIA data of the annual cost of driving 15,000 miles In terms of numbers, the dirty dozen of the meanest includes seven SUVs and three trucks. Lonely at the middle of the list is the sole electric, the GMC Hummer EV, which weighs in at 9,000 pounds. The council notes that “though EVs have lower emissions than similarly sized gasoline models, the Hummer demonstrates that size and efficiency, not just fuel source, are important factors in a carÂ’s environmental impact.” ItÂ’s also worth reminding prospective buyers that the average fuel cost of a vehicle on the “Greenest List” eats up only a fifth of the fuel cost of a vehicle on the Meanest List, “showing that greener options can also be more affordable.” The ACEEE also put out a "Greener List" of efficient gasoline and hybrid cars that don't require plugging in.  By the Numbers Green Cadillac Chevrolet Dodge Ford GMC Hummer Jeep Maybach Mercedes-Benz RAM Emissions Fuel Efficiency Green Automakers Truck SUV Electric Hybrid

2021 Cadillac Escalade First Drive | Opulence at a cost

The Cadillac Escalade is one of the most recognizable cars in America, both on the road and in the minds of consumers. It is equal parts profit machine and pop culture icon, and it sits atop GM’s heavy-hitting hierarchy of body-on-frame SUVs. Sure, Cadillac may hold most of the cards in the luxury SUV marketing game, but itÂ’s not the only player. For starters, the Lincoln Navigator is quite good, and it takes a very similar approach to truck-based luxury. Both are flashy, cushy and high-tech, and their tuning acknowledges that driving dynamics will never be the strong suit of vehicles this large – though ride comfort certainly can be. To make matters worse, the Europeans are getting serious about their three-row SUV game, and while they may not offer the same body-on-frame capability you get from the Americans, they more than make up for it with brand prestige and state-of-the-art engineering. With such solid competition, Cadillac was not in a position to just phone in the EscaladeÂ’s redesign. The highlight of that effort is a new platform, shared with the new Chevrolet Tahoe and GMC Yukon, that finally features an independent rear suspension. There's also the gorgeous and tech-rich interior featuring a 38-inch curved OLED dash screen, a new diesel engine option and – stop us if youÂ’ve heard this one before – Super Cruise. While the Escalade does share its fundamentals with the Tahoe and Yukon, the Cadillac-branded variant of GMÂ’s big truck platform always gets special treatment. Only the very base model is available without a leather interior, for example, and the aforementioned in-cabin tech is exclusive to the Escalade. YouÂ’re also limited to just two engine options: the standard 420-horsepower V8 that's the range-topping option on GM's other SUVs, and the new 3.0-liter Duramax turbodiesel inline-six that's good for 277 hp and a V8-matching 460 pound-feet of torque. Both are paired with GMÂ’s 10-speed automatic transmission, and thereÂ’s no price difference, regardless of trim.   Like CadillacÂ’s other offerings, the 2021 Escalade has a split trim hierarchy. Above the base model, you can choose one of two paths: Premium or Sport. The Premium Luxury and Premium Luxury Platinum are your more traditional, flashier options, with lots of chrome and a rich, warm interior. The Sport and Sport Platinum are for those who prefer a more modern, subtle aesthetic, with blackout exterior trim and more subdued interior finishes.
