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.

Ward's reveals annual 10 Best Engines list for 2013

Ward's Auto has released its annual 10 Best Engines award winners. The 2013 list covers the full width and breadth of the internal combustion spectrum, from a spate of efficient four-cylinders to the most powerful production V8 on the planet. As always, the entries must be available in a production vehicle in the first quarter of 2013 with an MSRP of less than $55,000. The supercharged 3.0-liter V6 from the Audi S5 held on for the fourth consecutive year, and BMW earned two spots on the list with its turbo 2.0-liter four-cylinder and turbo 3.0-liter inline-six.
Ford pulled in two awards for its 2.0-liter EcoBoost four-cylinder and and the supercharged 5.8-liter V8 from the Shelby GT500. Honda matched BMW and Ford with two wins of its own. Wards awarded the 2.4-liter four-cylinder from the Honda Accord Sport as well as the 3.5-liter V6 from the Honda Accord. Chrysler, General Motors and Subaru each garnered a spot on the list as well for the 3.6-liter V6 in the Ram 1500, the turbo 2.0-liter four-cylinder in the Cadillac ATS and the 2.0-liter four-cylinder the Subaru BRZ, respectively.

Cadillac ELR update delayed over autonomous drive systems issues

Rumors had been circulating that the 2016 Cadillac ELR would bow in Los Angeles recently, featuring, in Cadillac's own words, "engineering enhancements." The rumors and that quote are as far as it got – the updated ELR pulled a no-show in LA, and no one outside of the brand appears to know when it will appear. GM Inside News says its sources at Cadillac pinned the ELR's absence on some autonomous driving features not being ready to reveal. According to GMI, Cadillac insiders say the upgraded ELR will be a "highly autonomous vehicle," and the company needs more time to gets its systems polished. The site says "it's not unreasonable to assume that ELR will be [the] vehicle" that gets Cadillac's Super Cruise technology, but that seems a lot more involved than "engineering enhancements," and in September Cadillac said we'd see it sometime in the next two years. It's possible the wait for the 2016 ELR and its secrets might only be a couple of months: the next-generation Chevrolet Volt, which shares a platform with the ELR and whose engineering updates we know quite a bit about, is scheduled to appear at the 2015 Detroit Auto Show in January.
