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.

Autoblog's ultimate holiday rides

Over the hills and through the woods, it's the time of year when many of us visit family and friends for the holidays. But getting there can be a chore. It's cold and snowy across much of the United States, and even if the climate is favorable, the drive to grandmother's house often is not. Think back to holiday road trips of yore: They probably included crying babies, antsy children, hungover adults and frequent bathrooms stops all around. Now, we're all at different life stages here at Autoblog, and the perfect car for one staffer might be as useful as a team of Budweiser Clydesdales to another. Some of us bounce from family event to family event with children and a labrador in tow, while others prefer a quieter, simpler holiday. But whatever the endeavor, we all need wheels. With that in mind, here is the unofficial Autoblog list of the ultimate cars in which to tackle the holiday season. 2015 Ferrari FF To borrow a chestnut from Top Gear presenter James May, "As you'd expect, I've done this properly." That oddly voluptuous ruby bolide in the photo above? It's a 2015 Ferrari FF – all 652 all-wheel-driven horsepower of it. What makes a Ferrari the ideal for holiday time in PaukertLand? My Midwestern winter breaks are wonderful, but they're typically frenetic and slushy, involving a lot of schlepping from house to house and even city to city, not to mention inevitable last-minute runs for forgotten presents and dinner ingredients. Needless to say, a powerful V12 is a welcome ally for such duties. And this one isn't just a friend when the road is clear. The FF has been gifted Ferrari's novel 4RM AWD system, and despite sitting lower to the ground than, say, an SUV, it's a pretty effective tool for real winter driving, especially when outfitted with a set of snow tires. Unlike other Ferraris, it's also a rather practical thing, with legitimate seating for four adults and 15.9 cubic feet of cargo space – that's precisely as much room as a Mercedes E-Class – and you can fold the rear chairs and cram 28.2 cubes-worth of holiday cheer in the back. Okay, so it's far from cheap and fuel economy isn't that great, but who cares? Just drop a paddle-shifted gear or two, bury the throttle and Repeat The Sounding Joy. Ain't the holidays grand? – Chris Paukert Executive Editor 2015 Chevrolet Tahoe My Mom gives out more presents than any other human being I've ever encountered.

2015 Cadillac Escalade blings its way into LA

The new Cadillac Escalade sauntered out onto the Los Angeles Auto Show stage, showing off its new familial face and redesigned interior. That exterior, with its slim, wrap-over headlights and tall, vertical taillights (both made up of LEDs) is a subtle but significant departure from the past styling of General Motors' flagship SUV.
And while there's no shortage of stuff to discuss about the Caddy's exterior, its cabin is where the big changes happen. Aside from the column-mounted shifter, the cabin receives a heavy going-over, receiving Cadillac's new CUE infotainment system and a significant upgrade to the materials. Comparing it to furniture, Eric Clough, Cadillac's director of design for interiors, said, "An exceptional level of craftsmanship has gone into the redesign of the 2015 Cadillac Escalade, and it all centers on the premium materials and extensive use of cut-and-sew live stitching."
Under hood sits a 420-horsepower, 460-pound-foot, 6.2-liter V8. Fitted with direct injection and active fuel management, fuel economy for the big Escalade should get a much-needed boost beyond the current model's 14-city and 18-highway miles per gallon, although official numbers haven't been published quite yet. A six-speed automatic is the sole gearbox choice. Cadillac has also fitted the new Escalade with GM's magnetic ride control system, which should deliver a more refined ride than its predecessor.
