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.

Lutz dishes dirt on GM in latest Autoline Detroit

Autoline Detroit recently played host to Bob Lutz, and, as is always the case, the former General Motors vice chairman dished out some great commentary. Lutz was promoting his new book Car Guys vs. Bean Counters: The Battle for the Soul of American Business, and talk quickly turned to his role as it related to product development and high-level decision making at GM. While on the topic of brand management, Lutz revealed a few rather interesting tidbits about his former employer:
All Chevrolet vehicles were required to have five-spoke aluminum wheels and a chrome band up front, as part of the Bowtie brand's overall image.

2020 Cadillac CT5 prototype shows off more lighting details

The elusive 2020 Cadillac CT5 luxury sports sedan has once again been spotted by a spy photographer. This time, we get to see it from all angles, whereas last time we only saw it from the front. It still has quite a bit of fake body work, and it's very clear Cadillac still hopes you'll think this is a Charger, from the big hood scoop to the fake full-width taillights. Digging past those misdirects, we can find some new details about the car. First, the car's front lighting has developed further. There are production-ready headlights fitted that appear to have some sort of LED illumination. These production lights also fit the shape we saw on the last prototype, so they'll end high up on the body, extending slightly horizontally toward the grille. There's still a section that extends back along the fender, seeming to bridge the gap between current Cadillacs and the Escala concept from which this car takes inspiration. Another addition are the vertical LED accent lights. This is another trademark feature of both current Cadillacs and the Escala, but they were absent from the last prototype we saw. We also get a look at some of the grille's details. Instead of slats, this CT5 has a plastic mesh of small rectangles. The pattern is reminiscent of brickwork. These photos also give us our first look at the back of the CT5. It looks like a fairly typical Cadillac. It's much more conservative than the front end. There are some angular cutouts in the bumper to allow exhaust gases out. The taillights have the current Cadillac look with the top curving over the rear fender. We can't tell if there will be a horizontal element like on the Escala, due to the fake lights. We're expecting the CT5 to be shown sometime next year in time for the 2020 model year. Odds are it will use off-the-shelf Cadillac engines including the turbocharged 2.0-liter four-cylinder, naturally aspirated 3.6-liter V6, and the twin-turbo 3.0-liter V6. Now that Cadillac has revealed its twin-turbo 4.2-liter V8, we'll be interested to see if that shows up in a future CT5-V.
