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.

GM announces 6 recalls covering nearly 720k cars

General Motors has announced yet another sprawling recall campaign, with six separate elements covering 717,950 vehicles on US roads. At this point in 2014, it's starting to seem like there are more days with a GM recall than without. Perhaps most troubling about this latest volley, though, is that every vehicle is from the past few years, indicating that GM's quality woes may not be limited to pre-bankruptcy vehicles.
The largest element of this latest campaign covers 414,333 units, and includes the 2011 to 2012 Chevrolet Camaro, 2010 to 2012 Chevy Equinox, GMC Terrain and Cadillac SRX and the 2011 to 2012 Buick Regal and LaCrosse. Only vehicles with powered, height-adjustable seats are covered. In these particular cars and crossovers, the bolt that secures the height adjuster actuator may loosen of its own accord and in some cases fall out completely. If this happens, the seats will be able to move both up and down. GM claims the vehicles are safe to drive, provided drivers don't vertically adjust their seats. This particular issue has caused one crash and three injuries.

Ghostbusters' new Ecto-1 is an oddly uninspiring '82 Caddy

The Ghostbusters, or at least the movie franchise, will emerge from Hollywood's cobwebs this summer, but instead of the iconic 1959 Cadillac known as Ecto-1 that delighted big screen audiences in 1984, the new model may leave some scratching their heads. That's because this latest Ghostbusters draws its vehicular inspiration from a decidedly less interesting period in American automobile production: the 1980s. Starring alongside Kristen Wiig, Melissa McCarthy, Kate McKinnon, and Leslie Jones is a 1982 Cadillac DeVille hearse. The studio dressed up this tired Caddy to look the part, but something's amiss. Instead of the flamboyant fins and shiny chrome, the '82 is decidedly pedestrian and uninteresting. Even in 1982, it was kind of a dull choice for luxury car buyers. There's a reason Murilee Martin deemed the '70s and '80s the "malaise era." Built a couple of years before the original, Academy Award-winning Ghostbusters hit cinemas, the '82 DeVille represents one of Cadillac's lowest points bar the Cimarron. Under its hood might be Cadilac's new-for-1982 HT 4100 V8 engine, which featured what the brand referred to as "digital" fuel injection. With 135 horsepower and 190 pound-feet of torque, the DeVille didn't win stoplight races back then. Oddly, the V6 engine that came standard in the '82 Sedan DeVille produced the same horsepower but delivered an extra 15 torques, which made it both faster and more fuel efficient than the V8. These were bad times for General Motors, clearly, but the gas engines paled in comparison to Cadillac's first diesel. The company's LF9 5.7-liter diesel V8 was optional on the DeVille and we pity the unlucky buyers who checked that box. Generally credited as the engine that made "diesel" a haunted word in Detroit for 30 years, the 350-cubic-inch unit might actually be fitting for the Ghostbusters. On the bright side, the '82 is new enough that it may have carried a box or two of Hi-C's stellar, Ghostbusters-inspired Ecto Cooler. Maybe the mortician took his kid to Kroger one time, you never know. Fitting in In the original 1984 Ghostbusters, the '59 Caddy was a forlorn and forgotten piece of machinery waiting for a new lease on life. Character Dr. Ray Stantz picks it up and admits in the film that it needs "some suspension work and shocks ...
