Here's what it'll take to build a Jeep Grand Cherokee Hellcat

Let's get one thing straight: We want a 707-horsepower Grand Cherokee Hellcat to happen. Badly. The latest report from Motor Authority is encouraging; the bonkers SUV supposedly has a codename, Project K, and has been given the green light for production. Fingers crossed. You might be wondering why the Trackhawk isn't already a thing. Hellcat engines exist, SRT Grand Cherokees exist, so just combine the two, right? It's not quite that easy. Here, we outline what needs to happen, why it should be the quickest Hellcat vehicle out there, and why it won't come anywhere near 200 miles per hour. How To Build A Hellcat Jeep The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged V8. The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged Hellcat V8. Breathing is important on two counts: pulling in enough air for the combustion to put out 707 hp, and then cooling the various heat exchangers once the engine is up to temperature. Dodge did it with the Charger and Challenger, it can do it with the Jeep. This is one place where the Grand Cherokee's larger frontal area might be a boon, as it gives the engineers more surfaces through which to suck air. Once you generate the 707 horsepower and 650 pound-feet of torque, it has to get to the wheels somehow. Jeep's current SRT all-wheel-drive system will at least need some beefing up to handle the torque. It could require a more complete re-engineering. We at least know the ZF-supplied eight-speed auto, used in the Dodge Hellcat models, is up to the task. The Hellcat engine should fit in the Grand Cherokee, as it's about the same size as the 6.4-liter currently in SRT Jeeps, but the Hellcat is taller because of its supercharger. The hood may need to be raised or at least resculpted for clearance, as well as to address those cooling needs. Quicker Than Everything, But Not Faster 200 mph? We're skeptical, from both a physics standpoint and a legal one. A reminder of the quick/fast distinction: quick is acceleration, fast is road speed. The Jeep's all-wheel drive will help put the Hellcat engine's power to the ground in a more manageable way than the Charger and Challenger do through just the rear wheels. That means better acceleration times than the Dodges (11.0 seconds in the quarter-mile for the Charger Hellcat, 11.2 for its Challenger sibling).

Chrysler recalls 468,700 Jeep Grand Cherokees, Commanders over rollaway risk

Chrysler has issued a recall covering a combined 469,000 units of the 2005-2010 Jeep Grand Cherokee and the 2006-2010 Jeep Commander (inset). Of that number, 295,000 are in the US, roughly 33,000 in Canada and Mexico and the remainder in other markets. It seems an electrical fault in the transfer case can allow the affected SUVs to shift into neutral on their own, while an Associated Press report says that Chrysler had "found cracks in a circuit board that turns the four-wheel-drive system on and off." The issue was discovered when an owner started his car remotely and it rolled away.
Chrysler is expected to begin notifying owners in June 2013, who can then take their cars to dealers. The dealer will reflash the final drive controller free of charge. There's a bulletin from the National Highway Traffic Safety Administration below with more information.

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.
