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.

May 2016: FCA wins, Ford and GM stumble on weak car volumes

The May 2016 sales numbers are in, and it looks as though FCA is getting some vindication for boldly cancelling two slow-selling car models. Meanwhile, Ford saw overall sales dip and GM's May volume took a big dive versus the same month in 2015. While Marchionne's decision to axe the Chrysler 200 and Dodge Dart has drawn criticism as being short-sighted, it's working for FCA so far. Although the Dart and 200 aren't out of production yet and no capacity has been shifted to crossover or trucks, May's numbers show that the emphasis on Jeep and Ram models makes sense right now. FCA's US sales rose 1 percent last month compared to May 2015, putting the year-to-date total at 955,186 vehicles, an increase of 6 percent compared to the same period last year. Standouts included the Jeep Renegade, Compass, and Patriot, and the Fiat 500X. Ram pickup sales were down 3 percent. And your fun fact is that Alfa Romeo sales were up precisely 10 percent, for a total of 44 4Cs sold versus 40 in the same month last year. At FoMoCo, the Ford brand took a hit to the tune of 6.4 percent from May 2015 to 2016, registering 226,190 sales last month. Lincoln showed improvement on its modest numbers, going from 9,174 to 9,807, a 6.9 percent increase. Overall, Ford was down 5.9 percent for the month to 235,997; despite the slump, year-to-date total Ford sales are up 4.2 percent to 1,112,939. Strong sellers included Escape, Expedition, F-Series, and Transit - big stuff. Most small and/or efficient models (Fiesta, Focus, Fusion, C-Max) saw sales slides. Fusion sales were also down, likely due to effects of model changeover to the freshened 2017 model. Ford has promised four new crossovers and SUVs by 2020 and if things keep trending this way the company will be able to sell them, but things could change in the next four years. GM saw the worst of it for domestic brands. Retail and fleet sales were down for each of the four divisions, with the May 2016 total dropping 18 percent to 240,450 vehicles. GM's year-to-date sales are down 5.0 percent in 2016 to 1,183,705. Both the Sierra and Silverado were down significantly, and the majority of Chevy, Buick, GMC, and Cadillac nameplates saw sales decreases, with both small cars and larger utilities included. Not even big stuff could help GM this month, it seems. We'll have more on the rest of the industry's May sales as those figures trickle in.

Cool car technology is cool until it breaks

Ah, technology – the beautiful date that impresses all your friends but costs you a fortune to keep happy, up-to-date, and working. Automotive News puts some numbers to the economic toll we're paying to jockey this technological Trojan horse, an analysis it sums up with "Technology is great - until you have to replace it." Back in 2000, for instance, you could replace a Cadillac Escalade taillight lens for $56.08, or replace the entire unit for $220.49. Crack the rear lens on your 2015 Escalade and you have to buy a new unit for $795 - there's no such thing as just replacing a lens anymore. What about headlights? It was $210 for an Escalade headlight in 2000, it's $1,650 for the current unit (pictured). This is nothing we didn't know, these are just hard numbers to demonstrate it. Edmunds recently provided the same with its sledgehammer-bashing of the 2015 Ford F-150, Tesla Model S buyers have been shrieking about repair costs to their electric sedan's all-aluminum bodywork, and used-car sites are full of articles about which expensive-to-repair features to steer clear of if you want to avoid big repair bills. Those expensive bits increase the price of a car - Kelley Blue Book says the average price of a car is now more than $33,000 - and that raises rates for repairs and insurance. This comes in spite of some carmakers that have been collaborating with insurance companies and repair shops at the design stage in order to engineer parts that are easier and less expensive to replace. But the tech can have its cost-saving benefits: a 2011 study by the Highway Loss Data Institute found that Volvos fitted with that company's City Safety feature "filed 27 percent fewer property-damage liability claims" than luxury SUVs without it, and just last month the Insurance Institute for Highway Safety called adaptive headlights one of the top four crash-preventing technologies on cars today (after coming out against them in 2006). So yes, the technology costs a mint when it needs to be fixed - but being able to avoid an accident in the first place might make it worth it.
