The Hemi deserves to die | Opinion

Hi. I'm Byron and I love V8s. I want them to stick around for a long, long time. But not all V8s are created equal, and I will not mourn the passing of the modern Hemi. You shouldn't either. While we may agree that its death is untimely, if you ask me, that's only because it came far too late.  Stellantis’ announcement of its new, turbocharged inline-six that is all but guaranteed to kill off the Hemi V8 has led to quite a few half-baked internet takes. The notion being suggested by some, that automotive media were brainwashed into believing the Hemi was in need of replacement, is so far divorced from reality that I openly guffawed at the notion. Journalists have been challenging Chrysler, FCA and now Stellantis for years to deliver better high-performance engines. The response has always been the same: “Why?” Why replace a heavy V8 with a lighter, all-aluminum one? Why repackage powertrains for smaller footprints and better handling vehicles? Why be better when “good enough” sells really, really well? I too mourn the departure of good gasoline-burning engines, but since when was the Hemi one? HereÂ’s a quiz: Name every SRT model with an all-aluminum engine. TimeÂ’s up. If you named any, you failed. They donÂ’t exist. This isnÂ’t GMÂ’s compact, lightweight small-block, nor is it a DOHC Ford Coyote that at least revs high enough to justify its larger footprint. The Hemi is an overweight marketing exercise that happened to be in the right place at the right time. That time was 2003, when Chrysler was still Chrysler — except it was Daimler-Chrysler and the "merger of equals" was doing a bang-up job of bleeding the company's cash reserves dry while doing virtually nothing to address its mounting legacy costs. "That thang got a Hemi?" was emblematic of the whimsical, nostalgia-driven marketing of the colonial half of the "marriage made in heaven." That was 20 years ago. 20 years prior to that, emissions-choked American V8s were circling the drain faster than a soapy five-carat engagement ring in a truck stop sink.

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).

Updated 2014 Jeep Grand Cherokee ace same controversial moose test it failed in 2012 [w/video]

Some background: one of the more scandalous international incidents of he-said/he-said from 2012 was when Swedish magazine Teknikens Varld put the Jeep Grand Cherokee through its "moose (or elk) test" and reported that the SUV nearly rolled over. That lead to a whole lot of accusations and rebuttals: more than one website and Chrysler's own blog reported that the Jeep was overloaded; Chrysler said Teknikens printed the magazine then let Chrysler respond, Teknikens answered all of the charges in a lengthy post and said Chrysler was given a chance to comment before it went to print; when Chrysler sent investigators to oversee the test and the Jeep didn't go up on two wheels as it did in the first test, furthermore all four wheels stayed on the ground when Auto Motor und Sport tested a Grand Cherokee in the same way.
Teknikens then re-ran the test with a new vehicle and said it's been doing this test since the 1970s, uses the loading information that Chrysler provides to the Swedish motor authority and the previous Grand Cherokee passed with no problem. In the second test, the Jeep failed again, then it gave Chrysler engineers access to the car's electronics and ran the test again. In that second round the Grand Cherokee didn't repeat the lurid two-wheel action, but in eleven runs it blew out front left tire seven times. Chrysler still objects to the results of all of those tests and maintains that vehicle was safe.
The 2014 Grand Cherokee was given its shot at the gauntlet in the latest round of moose tests, and Teknikens Varld reports that it passed without any problem at all, its stability control working perfectly, controlling motion at low speeds and all the way up to 44.1 miles per hour.
