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.

Man trapped in Cadillac XLR for 14 hours after battery dies

A 75-year old Cleveland man ended up trapped in his 2006 Cadillac XLR for 14 hours last month, according to a story reported by the Detroit Free Press. The owner of the car, Peter Pyros, hopped into his roadster to back out onto his driveway, but he quickly learned that the battery was dead. He was "trapped" because the doors use an electric button to activate the door latch to open the door. Since the battery was dead, the buttons did nothing. Now, GM planned for an eventuality like this by placing a manual door release handle on the ground next to the seat. It's marked with a red diagram of the driver-side door opening. There's also a section about it in the owner's manual. The only problem here, was that Pyros says he didn't know the release was there, and he didn't have his owner's manual in the car. Because of this, Pyros may not have made it out alive if not for a neighbor coming to his rescue. "I came to the conclusion that I was going to die ... I was at peace with it. I asked God to help me twice, then I said, 'OK, God if this is the way I'm supposed to die, I will die,'" Pyros said to reporters. There's every chance he could have died in the car, too. Temperatures in Cleveland hit 77 degrees the day he was in the car, and he said it was unbearably hot and difficult to breathe after only 30 minutes sealed inside. Pyros reportedly tried yelling, pounding on and even trying to break the car's windows without success. At one point, Pyros wrote a note to his nephew explaining what happened if he ended up dying. What eventually saved him was a curious neighbor who came to investigate after he noticed his garage door was still open late at night. His neighbor called the police after he found him in the car, and emergency personnel actually ended up charging his car's battery up enough to get the electric door release to work. Of course, after everything settled down, there are now lawyers involved. They're going after GM, with an argument accusing the automaker of not making the emergency latch more obvious both in the car and in the owner's manual. GM doesn't appear to be having any of it. Here's its statement on the matter: "Because this varies by make and model, drivers should review the door lock section of their owner's manual, and follow up with their dealer or customer assistance center if they have any questions," GM spokesman Tom Wilkinson wrote to the Free Press. This type of door release isn't particularly uncommon for GM vehicles.
