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 teases production ELR ahead of Detroit Auto Show

General Motors has just confirmed that the 2014 Cadillac ELR will make its official debut next month at the 2013 Detroit Auto Show. We've already seen the ELR testing earlier this year using the same range-extended electric drive system as the Chevrolet Volt, and based on the shadowy image above, we're happy to see that the coupe's styling has stayed pretty true to 2009 Converj Concept.
The two-door ELR will be built alongside the Volt at GM's Detroit-Hamtramck plant starting later next year. Aside from this info, Cadillac has remained tight-lipped on the specific details of the car. But all that will all change on January 15.
Until then, all we have to offer you is the press release posted after the jump.

GM recalling 524k vehicles over hood latches and toe link nuts

Just hours after confirming to Autoblog its intention to recall 97,540 vehicles in the US (117,651 in North America) for a possible manufacturing defect in the chassis control module of several models, General Motors is issuing two more campaigns that affect another 379,401 units in the US (524,384 in North America).
One campaign covers 290,107 US examples of the 2010-2015 Cadillac SRX and the 2011-2012 Saab 9-4X because the "rear toe link adjuster lock nuts" may be improperly torqued. If not up to spec, the toe adjuster link could separate and allow the wheel to shift while driving, making the handling unstable. GM says that it knows of three crashes and two injuries as a result of this problem. Dealers are inspecting the nuts and installing a new link assembly, if necessary. Autoblog first reported about this potential issue when it showed up on a list of recalls from Transport Canada.
The second recall is for 89,294 examples of the 2013-2015 Chevrolet Spark in the US manufactured from January 17, 2012, through July 29, 2014. According to GM, "corrosion can cause the secondary hood latch striker to stick in the open position." If this happens, and the primary latch also isn't engaged for some reason, the hood could fly open while driving. About 13,000 of these affected Sparks are at dealers and are being held until repaired. The fix requires replacing the hood striker. GM isn't aware of crashes, injuries or fatalities caused by this problem.
