How Cadillac improved power output in 2016 ELR by 25 percent

Earlier this year, Cadillac announced that the 2016 ELR would come with a big price drop and a powertrain that packs 25 percent more power output. That's a lot more oomph, but it didn't sound like the Caddy engineers made any major changes to the engine or motors. So, what happened? Let's refresh our memories with the numeric details. The 2016 car is 1.5 seconds quicker to 60 miles per hour than the 2014 model (there was no 2015), down to 6.4 seconds. The 2014 put out 295 pound-feet of torque. For 2016, it will be 373 lb-ft. The specific breakdown of the various components in the powertrain has not been disclosed, but from what we can tell, the two electric motors and the 1.4-liter inline-four engine in the new ELR are not that much different than those in the old one. Sam Abuelsamid, senior research analyst at Navigant Research (and former writer here at Autoblog) said that any of the unspecified upgrades would be difficult to tell on a part-by-part basis, but the overall effect will be noticeable. "The changes to the ELR as I understand them are analogous to getting more performance out of a 1965 Mustang with the entry version of the 289 cubic-inch V8. You can replace the carburetor with a larger version that enables more air and fuel to flow into the engine, thus producing more power. The basic engine hasn't changed, but power capability is being unleashed by feeding it more." "Cadillac has changed components in the power electronics to enable more current flow into the motor and thus produce more torque. When you do this in the Mustang, you probably need to replace the rear axle gears and use a beefier clutch to transmit the power to the wheels. Similarly, the ELR probably has some upgraded clutches, bearings, and gears to withstand the increased total output." Cadillac spokesperson David Caldwell told AutoblogGreen in an email that the new ELR does indeed have more than just new lines of code. "One could not 'reflash' a previous ELR to get the performance of a 2016," Caldwell said. "If one only changed software you would not get the performance upgrade fully, as the 2016 creates higher current, more power. So these have been upgraded physically – hardware.

Cadillac ELR regen on demand brakes win 2014 Green Car Technology award

Just like the Oscars, Green Car Journal decided a few years ago to up the number of nominees for its annual award. For the annual "Green Car of the Year" award, given out at the Los Angeles Auto Show each year, there are five finalists. For the "Green Car Technology" award, there are a fantastic ten. At the 2014 Washington Auto Show today, the Cadillac ELR and its regen on demand brakes managed to beat out the nine other finalists to claim the second annual "Green Car Technology" award. What is the purpose of the "Green Car Technology" award? Green Car Journal says it wants to reward "technologies that enable significantly improved environmental performance in vehicles today," which is why only fuel-saving technologies that were "in use on American highways during the award year" can be considered. The Caddy's brakes beat out the Acura Sport Hybrid SH-AWD powertrain, the Audi 3.0-liter turbodiesel engine, the BMW carbon-fiber passenger shell from the i3, the 1.0-liter EcoBoost engine used by Ford, the plug-in hybrid powertrain in the Honda Accord, Hyundai's hydrogen fuel cell technology, the regenerative brakes in the Mazda i-ELOOP, the plug-in hybrid powertrain used in some Porsche models and, finally, the Ram 3.0-Liter EcoDiesel engine. Last year, Green Car Journal gave Mazda's Skyactiv technology the inaugural Green Car Technology award. Cadillac ELR Regen On Demand Wins 2014 Green Car Technology Award Green Car Journal Lauds Cadillac's Electric Car Tech at Washington Auto Show WASHINGTON, Jan. 22, 2014 /PRNewswire/ -- Cadillac's innovative Regen on Demand technology has taken top honors as the winner of Green Car Journal's 2014 Green Car Technology Award™. The prestigious award was presented at a Green Car Journal press conference during the Washington Auto Show's second Policy Day. "Cadillac has cleverly evolved a common electric-drive efficiency system into an intriguing feature that adds a new dimension to the driving experience," said Ron Cogan, editor and publisher of Green Car Journal and CarsOfChange.com. "Ever-increasing efficiency is crucial to our driving future, yet efficiency itself is not an attraction for a great many car buyers.

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.
