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.

New Takata problem results in recall of 414 GM vehicles

An airbag-inflator rupture discovered by Takata during testing has resulted in a new recall affecting 414 vehicles from General Motors, including 395 of them in the US. This latest campaign covers 2015 model-year examples of the Buick LaCrosse, Cadillac XTS, Chevrolet Camaro, Equinox, Malibu, and GMC Terrain. There are no reported breaks in any of these vehicles on the road, and the company estimates only one percent of them actually have the faulty parts. According to documents submitted to the National Highway Traffic Safety Administration (as a PDF), one side-airbag inflator failed a cold test at -40 Fahrenheit "releasing high pressure gas and propelling the separated components apart." The supplier told GM about the failure the next day. In these vehicles, the safety device might not only burst but the bag could inflate incorrectly, as well. GM and Takata say that a cause is not yet known, but they are "conducting an investigation." GM will begin notifying affected owners via overnight mail on Oct. 19. Dealers will replace the side airbag modules on all of the affected vehicles with new components outside of the suspect lot. All of the removed parts will also be collected for further study. Takata's faulty front airbag inflators have resulted in a serious scandal for the supplier. Initial figures indicated 34 million US vehicles are need of repair, though more recent figures have knocked that down to 23.4 million bad parts in 19.2 million automobiles. GM was already among the dozen automakers with models to fix, and some of its pickups were affected, along with the Saab 9-2X and Pontiac Vibe. GM Statement: General Motors is recalling 395 cars and crossovers in the U.S. because one of the front seat side air bags inflators may be defective. In the event of a deployment, the air bag's inflator may rupture and the air bag may not properly inflate. The rupture could cause metal fragments to strike the vehicle occupants, potentially resulting in serious injury or death. GM is unaware of any incidents involving vehicles with these components, which were part of a lot in which one inflator failed acceptance testing at the supplier. Dealers will replace the side air bag module or modules in affected vehicles. Including Canada, Mexico and exports, the total population of the recall is 414, GM estimates 1 percent of the recalled vehicles may have the defect.

2016 Cadillac CT6 First Drive [w/video]

Cadillac moved to New York, renamed its cars and crossovers, and made cutting-edge technology one of its pillars. It's fighting hard to attract new customers and kill its outdated reputation as an old-man car brand in the United States. Change happens slowly, and then sometimes, all at once. Enter the 2016 Cadillac CT6. This is Cadillac's range-topping sedan. It's almost as long as the Mercedes S-Class and BMW 7 Series, yet in some configurations, it's lighter than their smaller siblings, the E-Class and 5 Series. The CT6 is a rolling showcase of General Motors' latest and best technologies, with potential breakthrough features like Super Cruise semi-autonomous driving waiting in the wings. It comes in a wide variety of flavors. The CT6 starts as low as $54,490 with a four-cylinder engine and rear-wheel drive, which is the car that Cadillac hopes will be cross-shopped with the mid-tier Germans. The top-end CT6 Platinum with all-wheel drive and the 404-horsepower V6 begins at $84,460, and it could make S-Class and 7 Series buyers rethink American luxury. Put simply, the CT6 means everything to Cadillac, but it will mean different things to its customers. It can be the executive chauffeur with all the backseat accouterments. Or it can be the massive yet somehow kinda sporty and nimble rear-wheel-drive sedan that weighs only 3,657 pounds. We tried both versions and came away impressed with both the strategy and the execution. It's a little strange to think that Cadillac doesn't offer a V8 in its biggest sedan. Taking the wheel on a sunny, cool day in rural San Diego County, we wonder if a 2.0-liter four-cylinder engine has what it takes to really move this giant. Our concerns quickly dissipate – this engine is also under the hood of the Chevy Camaro, and its 265 hp and 295 pound-feet of torque are more than up for the task. The big sedan handles curvy mountain roads adeptly. There's not a lot of roll for a car this size, even when we're aggressively whipping through tight turns. This poise comes from the CT6's rigid, lightweight aluminum and steel structure called Omega. We switch through the driving modes but settle on sport for the dash to the lunch spot. The steering is surprisingly tight and the brakes have strong response with little pedal travel. After a quick bite in an old mining town called Julian, we take off in the spotlight CT6, the Platinum trim, powered by the 3.0-liter twin-turbo V6. It's an enjoyable car to stretch out on the highway.
