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 CT6 shows its face in 2015 Oscars ad [w/video]

Have you been watching the 2015 Oscars? No? Then you've missed your very first look at Cadillac's long-awaited flagship, the imaginatively named CT6. Don't worry folks, we've got the entire spot, titled The Daring: No Regrets, available below. Marking the start of the new Dare Greatly campaign, the 60-second spot will be joined by three others during the Oscars' broadcast, and features a number of unconventional luminaries from the worlds of fashion, finance, technology and film, contrasting their common beginnings with their exceptional accomplishments. It's a powerful spot... and then the CT6 arrives. Asking "How dare a 112-year-old carmaker reinvent itself," a white CT6 is spotted (viewed through what looks like a bad Instagram filter) cruising slowly down a New York (we assume) street. The car itself is big and wide – properly American and Cadillac in its proportions – and features a very handsome evolution of the latest CTS' styling, with a new take on the brand's distinctive headlight and grille design. Have a look at the photo above, watch the ad and let us know what you think of both the commercial and the car that stars in it, down in Comments.

Buy a Mosler Twinstar, the V16 Cadillac you almost wanted [w/video]

Cadillac was once famous for opulent, V16 luxury vehicles, but this bizarre 16-cylinder 1999 Eldorado that's for auction on eBay Motors isn't much like its ancestors. Dubbed the TwinStar, this beast features a Northstar V8 with 275 horsepower to drive the front wheels and a second Northstar with 300 hp is in the trunk to spin the rear axle. Each mill has its own four-speed automatic gearbox, and the result is a total of 575 hp of all-wheel drive fury in an incredibly weird package. The TwinStar's interior and exterior certainly don't hide the odd powertrain setup. To fit the engine in the trunk, the builders pushed the rear wheels further back and lengthened the wheelbase. There are also scoops low on each side to funnel air to the V8. Inside, there's a second ignition on the side of the center stack, and a digital instrument cluster replaces the glove box. It's sure to confuse any passenger you can convince to take a ride in this thing. Mosler, the supercar company known for models like the MT900, built five TwinStars, according to the auction. The seller links to the original review by Car and Driver, and the magazine noted that the sensation of the two engines working in tandem was rather odd. However, the TwinStar was a capable performer and ran to 60 in 5 seconds in its test. If you want to start your new year with the oddest vehicle possible, the TwinStar's auction sits at $5,600 with the reserve not met as of this writing, and it ends January 2, 2016, at 8:00 PM ET. If you can't wait that long, the dealer lists the car online for $39,900. There's also a spirited conversation on Bring a Trailer about this automotive oddity.
