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.

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 upgrades ATS sedan to match new coupe

The big news when it comes to the Cadillac ATS for 2015 is surely the addition of the new coupe model, but that doesn't mean that Cadillac has forgotten about the sedan as well. In fact GM's luxury brand has rolled out a few choice enhancements for the four-door to bring it more in line with the new coupe.
Among those changes that we spotted a couple of weeks ago is a new front fascia that incorporates the brand's new wreath-less emblem, and a sleeker front bumper. The interior has been upgraded as well with new trim options as well as some new tech including Siri Eyes Free functionality, dictated text messaging and optional inductive smartphone charging.
Though the ATS Coupe does away with the base engine, sedan buyers can still opt for the 2.0-liter four with 202 horsepower and 191 pound-feet of torque. The 3.6-liter V6 carries over unchanged at 321 hp and 275 lb-ft, but the 2.0-liter turbo four gets the upgraded torque rating of 295 lb-ft (the highest in the range) to go with its 272 hp. Some new color choices are also among the upgrades you can read more about in the press release below.
