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 recalling 2013 Buick LaCrosse, Cadillac SRX over transmission software

The National Highway Traffic Safety Administration has issued recalls for the 2013 Buick LaCrosse and 2013 Cadillac SRX due to a problem with the software for the transmission controller. On about 27,000 SRX and LaCrosse models, the transmission could accidentally be shifted to Sport mode, which would reduce the amount of engine braking drivers experience.
NHTSA says this could increase the risk of a crash, but, fortunately, the required fix is simply an update to the software.
While we're on the subject of General Motors vehicle recalls, a small number (48) of compressed natural gas versions of the 2011 Chevrolet Express are also being recalled for a potential risk of fire or explosion. Yikes. Both official recall notices are posted below.

Corvette's Performance Data Recorder headed to other cars, will Cadillac ATS-V be first?

For 2015, the Chevrolet Corvette Stingray gained a novel piece of high-performance technology: The Performance Data Recorder. This trick system combines video from a front-mounted camera with in-car data and GPS information to help drivers record and study their lap times, complete with data overlays. While it's a clever tool for track days, it's also finding popularity as a built-in dash cam of sorts. To this point, the technology has been a Corvette exclusive, but General Motors' executive vice president of global product development, Mark Reuss, has confirmed to Autoblog that it will soon be available in other vehicles.
At a media luncheon on Thursday, we asked whether GM was keen to expand usage of the technology to other models, and if we could expect to see something soon. Reuss coyly replied, "What's soon?" When we suggested the 2016 Cadillac ATS-V (which is scheduled to debut at next week's LA Auto Show), he replied, "There will be other uses, and it won't be that far away. How's that?"
Certainly not an outright confirmation, but we wouldn't be at all surprised to see the next high-po Cadillac roll under the klieg lights at the Los Angeles Convention Center next Wednesday brandishing more than just 450 horsepower.
