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.

GM pauses 3.0-liter turbodiesel production due to a supplier shortage

General Motors confirmed it has temporarily stopped taking orders for trucks and SUVs equipped with the 3.0-liter Duramax turbodiesel six-cylinder engine. It blamed the last-minute pause on a supplier-related shortage. Website TFL Truck first reported the news, and a representative from General Motors quickly confirmed it. The spokesperson explained the issue is due to a "temporary part shortage" and added that production will resume "as soon as possible," meaning the Duramax engine (which is called LM2 internally) is not going away permanently. Additional details are not available, so we don't know if the issue is related to the ongoing chip shortage. Rather than delay deliveries and create a backlog, General Motors is reportedly asking its dealers to encourage buyers who want a turbodiesel engine to instead select either the 5.3-liter V8 or the 6.2-liter V8, depending on the model selected. Both are gasoline-powered units. There's no word yet on when Duramax production will resume. The shortage affects several models, including Chevrolet's Tahoe, Suburban, and Silverado 1500 and GMC's variants of these trucks. Cadillac's Escalade is temporarily diesel-less as well. Heavy Duty variants of the Silverado and the Sierra are not affected because they're powered by a different Duramax engine with eight cylinders. Motorists seeking a full-size SUV powered by an efficient turbodiesel engine are temporarily out of options because the Tahoe/Yukon and the Suburban/Yukon XL had the segment to themselves. The Duramax was surprisingly popular, too: in May 2021, GM Authority reported that the turbodiesel straight-six represented 8% of Suburban sales and 6% of Tahoe sales. Installed in a rear-wheel-drive Tahoe, the engine returns 21 mpg in the city, 28 mpg on the highway, and 24 mpg in a combined cycle, figures that make the body-on-frame behemoth more efficient than the unibody, front-wheel-drive Chevrolet Blazer that's 20 inches shorter and approximately 1,700 pounds lighter.

2021 Cadillac Escalade shown inside and out in leaked photos

Fresh off the official reveals of the all-new 2021 Chevrolet Suburban and Tahoe, here come leaked images showing the redesigned version of their upmarket sibling, the Cadillac Escalade, inside and out. The images were posted on Instagram by user @allcarnews, with a hat tip to Jalopnik, and give us our best look yet at the unadorned exterior and the new interior.           View this post on Instagram                       A post shared by A L L C A R N E W S (@allcarnews) on Dec 11, 2019 at 12:22am PST Let’s start with the body design of the large luxury SUV, with bears strong echoes of both the aforementioned Suburban and Yukon, albeit with a chrome stripe along the lower doors and chrome trim framing the windows. Then thereÂ’s the redesigned grille, which looks like a larger-maw version of the XT6Â’s grille and adopts the same horizontal LED headlights. Instagram commenters also liken the exterior to the new XT6, CadillacÂ’s smaller three-row crossover, and even the Hyundai Palisade. The swept-back, slightly tapered rear end in profile even reminds us a little of the Lincoln Aviator. All of which will beg the question of whether Cadillac has done enough to distinguish its flagship SUV to compete against the Lincoln Navigators of the world.             View this post on Instagram                   (UPDATED) LEAKED: 2021 Escalade ? _____________________________________ [12/11/19] (NEW INTERIOR SHOTS) CadillacÂ’s Escalade for 2021 has been leaked and well.. the exterior is subjective.. What I will point out is the side profile which is unfortunately still identical to the Tahoe & Suburbab albeit with a chrome bar on the bottom and chrome window frame trim. The rear gets full sized LED verticals taillights again, but now more integrated into the rear. The front is big and loud but looks like a blown up XT6. After reading your comments, it seems a mixed bag, especially with the horizontal headlights (which i lightened to show the elements) but the massive verticals LED DRLÂ’s remain thankfully. ???????????? ???????????? ???????????? ????????? ? @Allcarnews Spec Sheet: Powertrain wise there will be a carry over 6.2L 420HP+ V8 paired to a 10 speed auto gearbox. A supercharged V8 version (or TT V8) will be coming in the future with up to 650HP in some sort of V designation. Expect blacked out wheels, trim and grille. ? ???????????? ???????????? ??????????? But..
