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.

2016 Cadillac ELR gets more power, $9,000 price drop

Cadillac has announced a series of updates to the ELR for 2016 that promises to make the plug-in hybrid luxury coupe a more desirable proposition. Perhaps chief among them is a price drop of $9,005 compared to the slow-selling 2014 model. The news follows an announcement yesterday that the Chevy Spark would get a $1,500 price drop. Cadillac is quoting a net price for the updated ELR at $58,495, which is obviously substantially less than the $75k it was asking for the previous version. But it's important to note that the new price is listed after US federal tax credits. The 2014 model came in at $67,500 after the full $7,500 tax credit, so math tells us that Cadillac has slashed the price on the 2016 ELR rather dramatically by about nine grand with a new MSRP of $65,995. One big upgrade on the performance front is a 25-percent boost in output from the hybrid powertrain that marries a pair of electric motors to a 1.4-liter inline-four gasoline-burning generator. The increase is said to be enough to drop 1.5 seconds off the 0-60 time, now quoted at 6.4 seconds. It'll travel for up to 39 miles on electric mode alone, but with the generator spooled up will go up to 330 miles before needing to stop. The engine management software has also been updated and the regenerative braking system reconfigured as well, but GM's luxury division didn't stop at the powertrain, fitting the 2016 ELR with a raft of other enhancements. Visually there's a new grille with the marque's latest emblem embedded. The suspension has been stiffened, the steering recalibrated and the brakes optimized for better feel. Cadillac is also throwing in the previously optional Driver Assistance package of active safety systems as standard, with adaptive cruise control available as an option. And the infotainment system comes with OnStar, 4G LTE connectivity and on-board Wi-Fi. There's even a Performance Package available with 20-inch performance tires offering 10-percent better lateral grip, four-piston Brembo brake calipers up front to help reducing stopping distances by 12 percent, recalibrated dampers and steering and a thicker-rimmed steering wheel. Because of the higher rolling resistance tires, however, the Performance Package kills four miles off of the electric driving range.
