Watch this 650-hp Hennessey Jeep Grand Cherokee go from 0-60 in 3.9 seconds

Hennessey Performance Engineering has created an HPE650 package for the Jeep Grand Cherokee SRT fitted with the 6.4-liter Hemi engine. When it leaves the showroom floor it has 470 horsepower and gets from 0-60 miles per hour in 4.8 seconds. When it leaves Hennessey's garage floor after the upgrade it has 650 horsepower - 530 hp at the wheels, according to Hennessey - and gets to 60 mph in 3.9 seconds on its way to running the quarter-mile in 12.6 seconds.
There's more than just a Roots-type supercharger bolt-on, with ported cylinder heads and high-flow headers among the many changes made to the engine. You can watch this pre-2014 facelift silver model prove its spec sheet on the drag strip in the video below.

NHTSA closes investigation into Jeep Liberty fires

The investigation that the National Highway Traffic Safety Administration opened into the Jeep Liberty in October 2013 has been closed. NHTSA received two (!) complaints about fires starting in the driver's door, thought to be caused by the master power window switch. The initial estimate was that 80,000 Libertys could be roped into a possible recall, but according to a report in the Detroit News the agency examined records for 425,000 Chrysler products that used the same window switch, including the Dodge Nitro and Chrysler Town & Country minivan.
After canvassing 265 warranty claims related to the master switches, NHTSA concluded that the rate of fires compared to the "large population of vehicles" was rather low, and that there was no trend pattern behind the few issues it did find. Perhaps with that, and the closure of the trailer hitch investigation, the Liberty can finally rest in peace.

Fiat/PSA's dominance in small vans hangs up EU's merger approval

BRUSSELS — EU antitrust regulators are concerned about Fiat Chrysler and Peugeot / PSA's combined high market share in small vans and may require concessions to clear their $50 billion merger, people familiar with the matter said. The companies, which are seeking to create the world's fourth biggest carmaker, were told of the European Commission's concerns last week. If Fiat and PSA fail to dispel the European Commission's doubts in the next two days and subsequently decline to offer concessions by Wednesday, the deadline for doing so, the deal would face a four-month-long investigation. The EU competition enforcer, which has set a June 17 deadline for its preliminary review, declined to comment. Fiat was not immediately available for comment while PSA had no immediate comment. Hiving off overlapping businesses, usually a regulatory demand to ensure more competition, could prove tricky for the carmakers because of the technicalities. Fiat and PSA are looking to merge to help offset slowing demand and shoulder the cost of making cleaner vehicles to meet tougher emissions regulations. The deal puts under one roof the Italian carmaker's brands such as Fiat, Jeep, Dodge, Ram, Maserati and the French company's Peugeot, Opel and DS.
