Hennessy wastes no time in supercharging the 2015 Cadillac Escalade

The ink is still drying on the all-new 2015 Cadillac Escalade sales brochures, but that hasn't stopped Texas-based Hennessey Performance (HPE) from leaping out of the gate with its own high-performance variant. In stock form, the big fourth-generation Cadillac flagship arrives with a new small block naturally aspirated 6.2-liter Ecotec3 V8 delivering 420 horsepower and 460 pound-feet of torque. Fresh out of the showroom, the 5,900-pound SUV will sprint to 60 mph in 5.9 seconds.
While that is plenty fast for some owners, others don't want to be shamed by a 550 horsepower Mercedes-Benz GL63 AMG or a 510 horsepower Land Rover Range Rover Sport - both will leave the stock Escalade at a stoplight.
The team at HPE has come to the rescue with its HPE550 supercharger upgrade, which includes a belt-driven supercharger, air-to-water intercooler, recalibrated engine management software and a three-year/36,000 mile powertrain warranty. With 6 psi of boost, the direct-injected 6.2-liter is tuned to deliver an impressive 557 horsepower and 542 pound-feet of torque - gains of 32 percent and 18 percent, respectively, over stock. Although HPE isn't releasing performance figures as of yet, our math says that should be enough power to put the two Europeans in the Cadillac's rearview mirror. The company also offers a set of 20-inch lightweight H10 forged monoblock wheels, to further improve performance.

Cadillac explains origins of Lyriq EV name

We feel for Cadillac, a brand we're inclined to dub the Alex Rodriguez of the automotive world — so much obvious talent, its gifts warped by repeated questionable moves and an inability to conclusively close the deal on The Big Stage. And as with Rodriguez, the expectations are so high at the same time the disappointment is so entrenched that Cadillac gets no benefits of any doubts, the commentariat ruthless with criticism for anything less than an out-of-the-park home run. This latest news, like the Newton-meter torque-based naming scheme initiated earlier this year, likely won't help. GM Authority asked Cadillac about the origin of the Lyriq name for the coming battery-electric crossover. Global head of brand strategy Phil Dauchy explained three threads that went into the new moniker. In no particular order, one thread is that "Cadillac," according to Dauchy, gets more mentions in song lyrics than any other brand, including non-automotive brands. The Music Lyrics Database, while not exhaustive, supports the case: Cadillac has 31 pages of lyric mentions among bands from Rancid to Weird Al Yankovic, beating every other brand we could think of. So ... lyrics into Lyriq. The second thread is rolled up with Cadillac's move to proper names instead of alphanumerics for the sedan and crossover lines, all of those names to end in "iq," as well as the push into electric vehicles. Dauchy told GMA the nomenclature overhaul and the two-letter suffix "[signal] that Cadillac is bringing a different type of vehicle to market, one that works in concert with man, nature, and machine." He's bullish on swaying the public with the product, adding, "When you see [the Cadillac Celestiq], its size, presence and scale all connote the emotion associated with the name." The final thread that went into the Lyriq name the alliteration of brand and model names. As GMA phrased it, perhaps unsettlingly, "With Cadillac and the model name both ending in an 'ick' sound, these names roll off the tongue quite well." This brings up a question raised in a number of comments about the Lyriq, which asks whether the last syllable is pronounced "ick" or "eek." Until now, I've pronounced the coming crossover with an "eek" at the end. "Lyr-eek" strikes me as more luxurious, and "Celest-eek" sounds better to me than "Celest-ick," that latter model being the flagship EV that follows the Lyriq. Of course, it also makes me wonder if I've been pronouncing "Cadillac" correctly.

Steve Carlisle replaces Johan de Nysschen as head of Cadillac

Johan de Nysschen, a longtime automotive industry executive, is out the door at Cadillac after four years at the helm of GM's flagship luxury brand. Steve Carlisle will replace de Nysschen as General Motors senior vice president and president, Cadillac. Carlisle previously served as president and managing director of GM Canada. Travis Hester will replace Carlisle in that role, starting immediately. "We appreciate Johan's efforts over the last four years in setting a stronger foundation for Cadillac," said General Motors President Dan Ammann. That strong foundation is mostly seen overseas. Cadillac has seen record sales in China under de Nysschen's watch, but has continued to flounder in its home market of the United States with market share significantly lower than rival brands like Audi, BMW, Lexus, and Mercedes-Benz. Growth in the U.S. market is mostly happening with crossovers and SUVs, and Cadillac has been trailing its German and Japanese rivals on that front. The brand-new XT4 is seen as a big potential sales booster for the automaker, but its late arrival has already hurt the brand's sales figures here in America. "Looking forward, the world is changing rapidly, and, beginning with the launch of the new XT4, it is paramount that we capitalize immediately on the opportunities that arise from this rate of change," said Ammann. "This move will further accelerate our efforts in that regard." Carlisle will report directly to Ammann in his role as the head of the Cadillac brand. Related Video:
