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 recalls ELR coupe over stability control problems

Cadillac is recalling about 656 2014 ELR models made between September 26, 2013 and February 14, 2014, because of a fault with the electronic stability control system. On cars without adaptive cruise control, it's possible that diagnostics could prevent the system from telling the driver if ESC is on or off.
Cadillac has a software fix ready and repairs begin on April 17. Alan Adler, General Motors' recall and legal spokesperson, tells Autoblog that only about 55 of the affected cars are in the hands of owners. The rest are either on dealer lots or still at the factory. There have been no reported injuries or crashes caused by the fault.
The correction for the stability control system involves a software recalibration of the electronic brake control module that takes around 20 minutes to perform. While they use the same platform, the Chevrolet Volt isn't involved in this recall because it "uses a different a brake control module," said Adler.

2020 Cadillac CT4 spy shots reveal sedan-heavy approach in age of SUVs

You're looking at some pictures of the 2020 Cadillac CT4, which will be smaller than the upcoming CT5. And since they're both smothered in similar-looking camouflage, which is specifically intended to confuse, you might think they look pretty similar. In isolated photos, it's sometimes hard to tell which sedan you're looking at. In fact, when we first saw this car recently, we also thought it was a CT5. Here's how we know they're actually two different cars. Some background: The CT5 is slated to replace the CTS, and to try and find the balance that the old car couldn't achieve in the lineup. Cadillac's former CEO previously stated that this car would also fill in for the ATS, which is on its way out. Whatever it ends up being, it'll have to make a clear case for itself against the CT6 — it can't be too close in size and opulence, or they'll hurt each other in sales. And the CT5 can't be too small, or it will struggle against traditional midsize luxury cars. The CT4 could further complicate matters for the exact same reasons, just in a smaller package. How small can Cadillac make it? It seems poised to replace the wonderful-to-drive ATS, which was as allergic to sales as the XTS. This will give Cadillac a three-sedan lineup: CT4, CT5, and CT6. Let's hope there's enough differentiation between them to prevent consumer confusion and sales cannibalization — and that consumers understand the CT6's promotion via attrition to top dog in the sedan lineup. With all that out of the way, let's look more closely at the CT4 (above left) and CT5 (right). The CT4's greenhouse stops closer to the centerline of the rear wheels than the CT5's. That gives the CT5 a visually longer, leaner look, more of a semi-fastback arrangement. The CT5's rear vanity window should resemble the CT6's, with a glass element behind the door opening. The CT4 will have a more conventional vanity window in the door, like the ATS. Perhaps the quickest "tell" is the size of the side-view mirrors, which are rounder in the CT4 and leaner in the CT5. Out back, the CT4 has a lower cutout for the license plate than the CT5. The exhaust outlets are also different, although that may change for production. Remember, the big full-width rear lights are probably misdirection on the part of the GM camo team. The entire rear decklid of the CT4 has more roundedness to it, while the CT5's extra width gives it more room up top to spread the decklid out a little flatter.
