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.

J.D. Power study sees new car dependability problems increase for first time since 1998

For the first time since 1998, J.D. Power and Associates says its data shows that the average number of problems per 100 cars has increased. The finding is the result of the firm's much-touted annual Vehicle Dependability Study, which charts incidents of problems in new vehicle purchases over three years from 41,000 respondents.
Looking at first-owner cars from the 2011 model year, the study found an average of 133 problems per 100 cars (PP100, for short), up 6 percent from 126 PP100 in last year's study, which covered 2010 model-year vehicles. Disturbingly, the bulk of the increase is being attributed to engine and transmission problems, with a 6 PP100 boost.
Interestingly, JDP notes that "the decline in quality is particularly acute for vehicles with four-cylinder engines, where problem levels increase by nearly 10 PP100." Its findings also noticed that large diesel engines also tended to be more problematic than most five- and six-cylinder engines.

Cadillac CT4 and CT5 high-performance V cars spied

This summer, Cadillac teased much more impressive V-series models than the lukewarm CT4-V and CT5-V. Now we get a better look at both super sedans, each one boasting more aggressive, but subtle visual upgrades. Normally we would talk about the visual changes to each car individually, but the changes are nearly identical between the cars. They both get deeper chin spoilers and lower side skirts. The lower grille opening now features slatted sections on either end. The headlights, main grille and hood all look unchanged from the regular V models. The same goes for the rear bumpers and tailpipes. The rear spoilers on both are much taller, though. The wheels on the CT4 look about the same as the CT4-V, but the CT5 wheels look a bit different with more detail. We also get a good look at the wheel-filling brakes. Cadillac hasn't said anything concrete about the specifications of the hotter CT4 and CT5 models, except that they'll definitely be faster than the revealed V models. One thing we do know, thanks to our spy photographer's video from earlier this year (shown above), the CT5 will get a V8. Our bet is on it being the Blackwing twin-turbo V8 that's available in the CT6-V and CT6 Platinum. It would probably have at least the same output at the CT6-V at 550 horsepower and 640 pound-feet of torque. Expect the 10-speed automatic transmission to carry over with it. This drivetrain would also open up the possibility of all-wheel drive. As for the fast CT4, it could potentially revive the ATS-V's twin-turbo V6 with 464 horsepower and 445 pound-feet of torque. It would probably also get a 10-speed automatic and maybe all-wheel drive as an option.
