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 and Buick boost GM's return to growth in China

BEIJING — General Motors on Monday said continued market recovery from the COVID-19 crisis helped its China vehicle sales grow 12% on year in July-September, marking the Detroit automaker's first Chinese quarterly sales growth in two years. The second-biggest foreign automaker in China by units — after Germany's Volkswagen AG — said on Monday it had delivered 771,400 vehicles in China in the third quarter. That followed a 5% fall in the second quarter, when parts of China were still emerging from virus-busting lockdown measures. GM has a Shanghai-based joint venture with SAIC making Buick, Chevrolet and Cadillac vehicles. It has another venture, SGMW, with SAIC and Guangxi Automobile Group, producing no-frills minivans and which has started manufacturing higher-end cars. Sales rose 26% for cars under its mass-market Buick brand in the third quarter versus the same period a year earlier, while those of premium brand Cadillac jumped 28%, GM said in a statement. Sales of its mass-market Chevrolet marque fell 20%. Sales of no-frills brand Wuling grew 26%, whereas those of mass-market Baojun vehicles tumbled 19%. "GM's compact models returned to four-cylinder engines and that helped sales growth," said LMC Automotive senior analyst Alan Kang, referring to an attempt to market cleaner but noisier three-cylinder versions. "Cadillac also has a more complete lineup this year." China's biggest automakers' association expects overall car sales to grow by double digits in July-September versus a year earlier. Makers such as Toyota, Honda and Geely saw sales jump in the just-finished quarter. GM has seen its China sales suffer in a crowded market and slowing economy. To revive its fortunes, it plans to have electric vehicles (EVs) make up over 40% of new models in the next five years in China, where the government promotes greener cars. The automaker's Wuling Hong Guang MINI EV, a micro two-door EV with a starting price of 28,800 yuan ($4,200), was China's biggest-selling EV in August. GM's sales fell 15% in 2019 from a year earlier to 3.09 million vehicles. The automaker delivered 3.65 million vehicles in 2018 and 4.04 million in 2017. Related Video:

All-new 2019 Cadillac XT4 crossover debuts in New York

Cadillac spent years and years improving its mainline sedans, the CTS and ATS, turning them into awfully good impressions of BMWs from a few years before. The thing is, great sedans aren't selling, and crossovers sure are. Cadillac's XT5 is the only crossover in the lineup, something that's had American Cadillac dealers gnashing their teeth and wailing — although anyone they can upsell into an Escalade can staunch the bleeding. That brings us to the new XT4, which is smaller than the XT5 but even sharper than its bigger sibling. Let's take a closer look at this new two-row luxury crossover. For one, it's based on what Cadillac calls a unique platform. That may be true, technically, although it's likely related to the Equinox/Terrain on some level. Platforms are becoming quite flexible: Look at Volkswagen's MQB, under everything from Euro hatches smaller than our Golf to the three-row Atlas. Whatever else it is underneath the skin, all XT4s will share one powertrain: the corporate 2.0-liter turbocharged inline-four, paired to a nine-speed automatic transmission. View 14 Photos The engine puts out a healthy 237 horsepower and 258 pound-feet of torque, putting it just a hair underneath its closest domestic rival, the Lincoln MKC with the 2.0-liter EcoBoost. Of course, the 2.3-liter MKC beats the XT4 handily, but that's another story. Power is produced with the help of a twin-scroll turbocharger. All-wheel drive is available, with a driver-selectable rear axle disconnect to save a small amount of rolling friction. Cadillac estimates it'll be good for 30 MPG on the freeway, but we haven't seen official results to confirm that. A few other changes that'll affect driving: electro-hydraulic brake assist, a first for Cadillac and mainly a fuel-saving measure; and Continuous Damping Control, which alters the damper's valve continuously based on a number of parameters. It's almost certainly used here because it's lighter and less expensive than air suspension or MagneRide, and it is optional on XT4. CDC or no, all XT4s utilize a front strut and five-link rear suspension. All XT4s also ride on 18-inch wheels in various designs. The trim strategy is mildly interesting. The base model is the Luxury, and then you can choose a Sport (black exterior trim, unique wheels) or a Premium Luxury (bright trim and satin-brushed accents). The interior options are suitably upscale and premium, and we'll have more to say about them a little later when we can see this car up close.
