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.

[UPDATE] Cadillac Blackwing gets ticket to Italy, to go to work in a supercar

UPDATE: It seems MAT's belief it had secured a supply of Cadillac's 4.2-liter Blackwing V8 was premature, and based on a handshake deal before GM sold its Turin engine center to Italy's Punch Group. Shortly after Hagerty ran the story, GM sent a statement to the outlet reading, in part, "We do not have an agreement in place with Manifattura Automobili Torino (MAT) to provide or sell the Blackwing engine. ... Our team is following up with MAT president Paolo Garella to discuss the misunderstanding." MAT also submitted a statement to Hagerty, saying, in part, "We thank GM for the clarification. Although a signed agreement was not finalized between the parties, we were under the impression that our counterpart was committing to making this engine available to MAT at conditions yet to be defined. ... We hope that this misunderstanding will not compromise our relations with GM and possible future collaborations." The original article follows: Some necessary cost-cutting at Cadillac led to switching the new CT4, CT5, and Escalade to older platforms. The revised architecture plan meant Cadillac's newest top-tier products couldn't fit Cadillac's newest top-tier engine, the 4.2-liter twin-turbo DOHC V8 known as Blackwing. That engine would serve limited duty at full power in the now-dead CT6-V, and at reduced output in the CT6 Platinum V8 trim before ending its bright, brief domestic life. But the story isn't over, the rebirth of Blackwing coming from a most surprising locale: Turin, Italy. Before the canceled Geneva Motor Show, Hagerty spoke to Paolo Garella, CEO of Manifattura Automobili Torino; that's the company better known as MAT, makers of the New Stratos and contract engineering house for boutique screamers like the Aspark Owl electric hypercar, Apollo Intensa Emozione, and SCG003C. Garella told the outlet, "We have an agreement with General Motors" for a supply of Blackwings, which would be developed and built at the General Motors Propulsion Engineering Center (PEC) in Turin. Since 2005, the PEC has been used to develop GM's global diesel engines and electronics. MAT's plan is to put the V8 into a new limited-run car MAT is creating from its own design. Then another surprising turn: Belgium-based global auto supplier Punch Group bought the PEC, with plans to work with GM on projects in progress until at least the end of 2021. Nothing changes as far as MAT is concerned, except perhaps a chance for an even closer collaboration with Punch Turin.
