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.

Twin-turbo Cadillac CTS coming

Cadillac ATS coupe and sedan get Midnight Editions

Horror stories and fairy tales make a mint by having the scariest things happen at midnight, but automakers make a mint by marketing midnight. Chevrolet busted out a Silverado Midnight Edition early this year, followed shortly thereafter by an Impala Midnight Edition. In between those two we got the Cadillac CTS Midnight Edition, and now comes an ATS following in the zero-dark-thirty tradition, according to GM Inside News. The ATS Midnight Edition will add $1,695 to the sedan price and $600 to the coupe. For that cash outlay you get black chrome on the grille, around the windows, and on the rear fascia, 18-inch "After Midnight" wheels, "sueded microfiber" trim on the steering wheel and shifter, plus the Cold Weather Package with a heated steering wheel and heated front seats. Just those few exterior changes make a big difference up front, increasing the appeal and aggression of the sports sedan without being ostentatious. You can't go dark with just any old ATS, though. The package is limited to rear- and all-wheel-drive versions of the Performance trim. And the color palette is reduced to four hues: Crystal White Tricoat, Red Obsession Tintcoat, Phantom Gray Metallic, and Black Raven. The three possible interior combos are Light Platinum with Jet Black accents, Morello Red with Jet Black accents, and Jet Black with Jet Black accents.
