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 recalling nearly half a million Durangos and Grand Cherokees

Rule number one of public relations – save the bad news for Friday. Fiat Chrysler has adhered to that, announcing today that it'd be voluntarily recalling 467,480 SUVs. This latest recall could actually be thought of as a continuation of a September 2014 recall, relating to the fuel-cell relay. In that case, some 188,723 Dodge Durango and Jeep Grand Cherokee CUVs from model year 2011 were recalled. And this time, it's the Durango and GC in trouble again. FCA is adding crossovers from model years 2012 and 2013 to the fuel-pump recall, although only diesel-powered Jeeps with the 3.0-liter V6 that were sold outside of North America are affected this time around. As with the previous recall, deformities in the fuel-pump relay, which could affect its functioning. In most cases, FCA reports that the affected vehicles simply won't start, although they also could be prone to stalling. A new relay circuit will be installed that promises increase durability. Of the 467,480 vehicles being recalled, 338,216 were sold in the US market, 18,991 went to Canada and 10,829 were shipped south of the border, to Mexico. Outside of the NAFTA region, FCA is recalling 99,444 vehicles. No injuries or accidents have been associated with this recall. Statement: Fuel-Pump Relay February 27, 2015 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 467,480 SUVs worldwide to install new a relay circuit that improves fuel-pump relay durability. FCA US engineers have determined a condition identified in a previous investigation may extend to additional vehicles. The previous investigation, which led to a recall, traced a pattern of repairs to fuel-pump relays that are susceptible to deformation. This may affect fuel-pump function, preventing a vehicle from starting, or leading to engine stall. Of the two scenarios, the no-start condition is the more common. FCA US is unaware of any related injuries or accidents. The fuel-pump relay is located inside the Totally Integrated Power Module (TIPM), which also helps manage other vehicle functions. None of these other functions, including air-bag deployment, is affected by the fuel-pump relay. The new campaign affects an estimated 338,216 vehicles in the U.S.; 18,991 in Canada; 10,829 in Mexico and 99,444 outside the NAFTA region. Covered are model-year 2012 and 2013 Dodge Durango full-size SUVs and non-NAFTA 2011 Jeep Grand Cherokee mid-size SUVs equipped with 3.0-liter diesel engines.

Jeep 'trailer hitch' recall repair rates lag amidst reports of new death

The problem with exploding fuel tanks in the 1993-1998 Jeep Grand Cherokee and 2002-2007 Jeep Liberty in some rear collisions continues to be a problem for FCA US, formerly Chrysler. The campaign to fix the utility vehicles was first announced in June 2013 after 51 claimed fatalities, and the fixes reportedly began in January 2014. However, there continue to be new deaths blaming the problem in unrepaired models, according to The Detroit News, citing data from the Center for Auto Safety. The automaker initially refused NHTSA's pressuring to conduct a recall because the models met applicable crash standards when they were manufactured, but eventually, there was a compromise to inspect and fix about 1.56 million Jeeps. With the fuel tank located between the rear axle and bumper, the unusual fix was to install a trailer hitch for extra protection. The National Highway Traffic Safety Administration later agreed that the change would provide added safety in lower to medium speed crashes, but not high-speed crashes. The most recent fatality, according to The Detroit News, occurred on a Michigan freeway in November 2014 when a pregnant woman in a 2003 Liberty was rear-ended when traffic slowed. Her Jeep impacted the vehicle in front, rolled over and a fire resulted. The family reportedly plans to file a lawsuit against FCA. At issue has been the rate at which the vehicles are being fixed. In July 2014, the automaker estimated it could have all of the vehicles repaired by March 2015 thanks to additional hitch supplies. But by November, NHTSA claimed that only three percent of the recalled models had been fixed. FCA says it continues to work to notify owners, though. According to Chrysler spokesperson Eric Mayne to Autoblog, "We are processing approximately 1,200 vehicles per day. Every owner who schedules service is receiving service. As of Jan. 8, that total was 193,490." The company has also mailed out over two million notifications to owners, more than the number officially called in. Given the age of these Jeeps, many of them have had multiple owners, and historically, the older a vehicle is, the less likely the recall fixes are to be carried out. FCA is currently creating a video urging people to have the hitch installed to be released soon.
