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.

2015 Cadillac ATS Coupe favors cleanliness over radical lines

Though you might not know it from looking at vehicles like the XTS and Escalade, if you take a broader look at history, you'll see that Cadillac models have gotten a lot smaller from the tail-finned highway cruisers of old. At least when it comes to coupes, anyway. The Eldorado, in particular, kept getting smaller until it disappeared, its place taken in recent years by decidedly more compact XLR, CTS Coupe and ELR hybrid. What you see here, however, is Cadillac's smallest coupe yet.
Revealed today at the Detroit Auto Show is the new 2015 Cadillac ATS Coupe, the brand's first compact two-door coupe, and the first production car to wear the brand's all-new crest. It shares the same platform and wheelbase as the existing ATS sedan, but packs a wider track and unique bodywork that's decidedly more conservative and less unique in its angular styling than the CTS Coupe that it's likely to ultimately displace in the Cadillac lineup. Styling aside, the all-American luxury marque has engineered the ATS Coupe with a focus on reducing weight to the benefit of both performance and fuel economy, giving it near 50/50 weight balance front to rear with underbody aerodynamic elements helping it cheat the wind.
Buyers will be able to choose between two engines: a 2.0-liter turbo four and a 3.6-liter V6.

GM considering new powertrain options for large SUVs

Aside from the new General Motors offerings, there's not a whole lot of action going on in the fullsize SUV segment. That doesn't seem to be stopping GM from pushing the envelope in the market as Automotive News is reporting that the automaker is looking to introduce some new powertrain options into the Chevy Tahoe (and Suburban), GMC Yukon (and Yukon XL) and the Cadillac Escalade - all have been redesigned for the 2015 model year.
Now, we already know that GM and Ford are collaborating on nine- and ten-speed transmissions for a broad range of applications (including the big SUVs), but this new report says that GM is also considering other options as a way to one-up the competition and, of course, to optimize fuel economy. AN quotes Jeff Luke, executive chief engineer for GM trucks, as saying that "interesting powertrain technologies" are coming including a return of a hybrid SUV and possibly even a diesel engine. Although it sounds like the latter could come down to how customers respond to the 2014 Jeep Grand Cherokee EcoDiesel.
