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).

25,000 Jeep Grand Cherokee, Dodge Durango SUVs recalled over brake feel

Chrysler has announced that it is recalling over 25,000 Jeep Grand Cherokee and Dodge Durango SUVs from several markets over concerns about brake feel under hard braking. The affected models are from the 2012 and 2013 model years, although the actual dates of production aren't available. 18,700 are in the US, while 825 are in Canada, 530 are in Mexico and a further 5,200 outside of North America.
According to a statement, Chrysler was informed of the issue by a component supplier for the Ready Alert Braking system, which primes the brakes in anticipation of an emergency stop. A component in the system was restricting the flow of brake fluid too much.
As Chrysler is quick to point out, the way the brakes functioned was in compliance with regulations and there are no reported cases of drivers losing braking power. Instead, the issue rests with what Chrysler calls a pedal feel that "was not consistent with customer expectations." So it would seem Chrysler is being proactive and fixing a problem not because there's a legal issue at work, but simply because it doesn't feel the way the manufacturer wants it to. Well done.

Marchionne says no offers are on the table for Fiat Chrysler

MONZA, Italy (Reuters) - Fiat Chrysler (FCA) has not received any offer for the company nor is the world's seventh-largest carmaker working on any "big deal", Chief Executive Sergio Marchionne said on Saturday. Speaking on the sidelines of the Italian Formula One Grand Prix, Marchionne said the focus remained on executing the company's business plan to 2018. Asked whether FCA had been approached by someone or whether there was an offer on the table, he simply said: "No." The company's share price jumped to record highs last month after reports of interest for the group or some of its brands from China. China's Great Wall Motor Co Ltd openly said it was interested in FCA, but had not held talks or signed a deal with executives at the Italian-American automaker. The stock move was also helped by expectations that the company might separate from some of its units. Marchionne reiterated on Saturday that FCA was working on a plan to "purify" its portfolio and that units, such as the components businesses, would be separated from the group. He hopes to complete that process by the end of 2018. "There are activities within the group that do not belong to a car manufacturer, for example the components businesses. The group needs to be cleared of those things," he told journalists. Asked whether an announcement could come this year, Marchionne said it was up to the board to decide and that it would next meet at the end of September. He said the time was not right for a spin-off of luxury brand Maserati and premium Alfa Romeo and the two brands needed to become self-sustainable entities first and "have the muscle to stand on their feet, make sufficient cash". "The way we see it now, it's almost impossible, if not impossible, to see a spin-off of Alfa Romeo/Maserati, these are two entities that are immature and in a development phase," he said. "It's the wrong moment, we are not in a condition to do it." He said the concept of separating the two brands from FCA's mass market business made sense and did not rule out this happening in future, but not under his tenure, which lasts until April 2019. "If there is an opportunity in future, it would certainly happen after I'm gone. It won't happen while Marchionne is around," he said.
