Cadillac may not build Elmiraj coupe

Despite the fact that most everyone who has laid eyes on the Cadillac Elmiraj concept coupe loves it, General Motors insiders are still trying to prove the business case to build the car. And it's certainly not a guarantee.
"I want to see this car go into production badly. Very badly," Ed Welburn, GM's Global Head of Design, told Autoblog. But the Cadillac design studio is busier than it's ever been before, and the company is working on prioritizing which cars deserve to get the billion-dollar price tag needed to research and develop a new model.
No matter what happens, Welburn says the car has made its mark on Cadillac

Cadillac XT4-V on the way?

An anonymous photographer sent Cadillac Society two tightly cropped images of an XT4 crossover wearing two surprising badges. On the right, above the taillight, there's a 2.7 badge, In the lower right corner there's a V Series badge — the full-fat, multicolored V badge, not the monochrome V-Sport version. The images — assuming they're real — elicit more questions and no answers, the first being, is this the XT4 V-Sport that's been rumored since last October? Back then, GM Authority discovered front and rear images of such a vehicle hiding in plain sight, on a Cadillac site landing page. The backside of a thick-hipped XT4 is graced with the old V-Sport badge. We know the carmaker has split its V Series cars into two tiers, the lower intended to be less intimidating than before, the upper tier the continuation of the mongo V Series cars we've known and loved. The hints have been that the entry level will be called V Series, while the upper level takes the name "Blackwing," after the name of Cadillac's new 4.2-liter, twin-turbo V8 engine. With Mark Reuss himself having said, "We got rid of all the V-Sports," this supposed XT4-V offers more proof that V Series effectively represents a new V-Sport line. The only cosmetic giveaways to increased performance we can see are a carbon fiber trim in the license plate area, and an exhaust treatment similar to that on the recently introduced CT4-V. We're not certain what the 2.7 badge means for V branding on crossovers. The standard XT4 wears a 2.0 badge on the tailgate, representing its 2.0-liter four-cylinder with 237 horsepower and 258 pound-feet of torque. The XT5 gets a number, too, but the XT6 does not. GM's 2.7-liter four cylinder with 311 hp and 348 lb-ft first showed up in the Chevy Silverado, will get 320 hp and 369 lb-ft in the coming CT4-V, and has been predicted for the XT4-V. However, V cars — both Sport and Series — have never worn displacement badges. The new CT4-V and CT5-V go without numerical identifiers on their decklids. If there is an XT4-V on the way this year, we only have a few months before we see it and get some answers.

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.
