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.

Ringbrothers drops more hints about its wild SEMA creations

Ringbrothers isn't finished teasing its SEMA creations. First we got a sliver of rear quarter on a 1969 Chevrolet Camaro that revealed a bundle of carbon fiber and SEMA-obligatory deep-dish wheels. The Wisconsin tuner's now announced its litter of cars headed to the show and a few specs, along with two shadowy drawings. The Camaro, christened with the name Valkyrja and a two-tone paint job, gets stretched in two directions with severe fender flares to widen the body and an extended wheelbase. We're not sure what's happening with the Camaro's snout in the drawing, but under that bulging hood we'll find a 416-cubic-inch LS V8 from Wegner Motorsports. Wegner built the 416-cu-in supercharged LS3 V8 that powered Ringbrothers' 1,000-hp G-Code Camaro in 2016.  The second member of the gang is a 1969 Ford Mustang Mach 1 dubbed Unkl. The exterior begs for attention with a deep blue sea paint job, deep front chin spoiler, bulging hood, yellow brake calipers, and what looks like a racing number inside a roundel on the doors. Unkl gets its motivation from a 520-cu-in Boss V8 built by Kaase Racing Engines, rumored to throw about 800 hp.    Finally, Ringbrothers is bringing its Cadillac Madam V for another Las Vegas go-round after giving the custom coupe some updates. The Madam V is a 1948 Cadillac Series 62 fastback coupe body placed atop an ATS-V chassis, first shown in 2016. The firm didn't elaborate on the changes, so all we can expect for now are the coupe's postwar good looks mixed with new-millennium engineering, and a 3.6-liter twin-turbo V6 with 464 hp under that exceptionally long hood.    For any in attendance at the show, the Valkyrja Camaro debuts at the BASF booth on Tuesday, Nov. 5, 2019 at 9:30 a.m., the Unkl Mustang gets revealed a couple hours later at the Flowmaster/Holley booth, and the Madam V Cadillac will be on display throughout the show at the Ringbrothers booth.

Cadillac XT4 crossover reveals its lighting

The upcoming Cadillac XT4 compact crossover has once again been spotted, this time with less camouflage and an update to its lighting. Specifically, the little crossover is sporting production lighting front and rear, and it's sure to make the luxury SUV one of the boldest-looking Cadillacs. Part of the reason for this comes from the taillights. As we suspected from the last set of spy shots, the XT4 will have highly distinctive lights that run the full height of the C-pillar. Though it's a similar design to that of the Escalade, it's made more interesting by the significant forward rake of the rear pillar. Not only that, but that pillar is quite thick, too. The look is actually reminiscent of the old CTS wagon. Moving around the side, the reduced camouflage reveals that the doors and quarter panels are fairly conservative and lacking in many creases or bulges. We can make out the edges of what will likely be black plastic fender flares and rocker panel cladding. Finally reaching the front, we see that the headlights are similar to those of many current Cadillacs, including the recently refreshed XTS sedan. The main part of the lamp starts high up and is slightly horizontal like the Escala concept, but they extend over the fenders and a strip of LEDs descends down the front. A previous report noted the XT4 will be built in Kansas on the Chevy Malibu platform. That means it will be a front-drive-based vehicle likely offering both front- and all-wheel-drive. Under the hood will probably be at least one turbocharged four-cylinder engine, with a second, more powerful upgrade option a possibility. We expect to see the fully revealed model to show up by the end of 2018.
