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 introducing V2V communications on 2017 CTS sedans

While Audi has introduced vehicle-to-infrastructure technology in select cars in select cities, Cadillac is focusing on vehicle-to-vehicle (V2V) communications, and it all starts with the CTS sedan. Starting this month, the company will be adding V2V equipment to 2017 models. The feature will be standard on cars in the US and Canada. These V2V devices will allow these new Cadillacs to communicate with each other up to 980 feet away. The cars will be able to transmit and receive information on speed, direction, and location. An example of how this data can be used is in detecting a car coming up a side street that could pose a possible collision risk. The cars will also be able to transmit data about brake use, hazard lights, and low traction situations for advance warning of hazards. The warnings can be displayed on the instrument panel and heads-up display. Currently, the system only communicates with other CTS sedans equipped with the technology. According to Chris Bonelli at Cadillac part of the reason is that the CTS will be the only car with the equipment on US roads at the moment, but it also isn't currently set to communicate with other cars if they were to be offered right away. However, he said that the company is absolutely willing to work with other companies to make the system compatible if or when other cars are offered with the technology. This V2V system also doesn't send data to any sort of network, instead only communicating with nearby cars. For the time being, this precludes the possibility of receiving road condition information from cars that are farther away. But as Cadillac points out, it should work under any conditions with no delay since it isn't dependent on information from a network. As far as security is concerned, Bonelli told us that the Cadillac system does have firewalls and other security measures to keep it protected from interference. He also said the cars don't store any data they receive. In addition, none of the data could be used to identify a particular person. The cars use a radio frequency set aside by the government for this use. The introduction of this technology also puts Cadillac well ahead of proposed legislation by the Department of Transportation. The organization wants this type of short-range V2V communications equipment to be a standard feature by 2023, believing the technology could prevent many injuries and deaths due to crashes.

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.
