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 says its 8-speed transmissions will save 700 million gallons

Chrysler Group's TorqueFlite eight-speed transmission could be earning some serious green bragging rights if the company's projections are correct. The recently widely proliferated automatic gearbox, which is now in more than a million vehicles around the world, is poised to save drivers an estimated 700+ million gallons of fuel over the vehicles' lifetimes (an expected cost savings of $2.5 billion). In addition, Chrysler expects a reduction in CO2 emissions by more than six million metric tons. According to Chrysler, and depending on the vehicle, the TorqueFlite can improve fuel economy. The TorqueFlite autobox features particularly close ratios from fifth to eighth gear (see the press release below for the specific numbers), and uses low-viscosity fluid that doesn't need to be replaced. Transmission software adapts to the driving situation to optimize efficiency based on driver behavior, temperature, grade, stability control, and longitudinal and lateral acceleration. The TorqueFlite is capable of handling a variety of duties. As evidenced by the wide range of vehicles Chrysler Group has seen fit to equip with the eight-speed transmission, the TorqueFlite is capable of handling a variety of duties. Since its 2012 introduction, the TorqueFlite has gone from performing cog-swapping duties in Dodge Charger and Chrysler 300 models equipped with the 3.6-liter Pentastar V6 to changing gears in vehicles such as the Pentastar- and Hemi-powered Dodge Durango, Jeep Grand Cherokee and even the Ram 1500 EcoDiesel. For the 2015 model year, the eight-speed is finding its way into even more vehicles with the addition of a third version. In addition to the American-made TorqueFlite 845RE and 8HP70, the new 8HP90 will be manufactured in Saarbrucken, Germany. The 8HP90 is designed for higher torque loads, making it ideal for high-performance vehicles like the 2015 Dodge Challenger SRT Hellcat. The already-in-use 8HP70 will expand its duties to be used in 2015 Hemi models such as the Dodge Charger, Challenger, and Challenger SRT8. You can see the list of those benchmarks in Chrysler's press release below.

Stellantis reports record margins, $7B profits despite chip shortage

MILAN — Automaker Stellantis on Tuesday said it achieved faster-than-expected progress on synergies and record margins in its first six months as a combined company, despite suffering 700,000 units in lower production due to interruptions in the semiconductor supply chain. The company — formed from French carmaker Peugeot PSAÂ’s takeover of the Italian-American company Fiat Chrysler — reported net profit of 5.9 billion euros ($7 billion) in the first half of 2021, compared with a loss 813 million euros during the same period a year earlier, which was impacted by the coronavirus restrictions around the globe. Shipments rose 44% to 3.2 million units, while revenues rose 46% to 75 billion euros. “We are very pleased with the speed with which the new team has begun to execute as one company, as Stellantis,Â’Â’ Chief Financial Officer Richard Palmer told reporters. Semiconductor shortages accounted for 200,000 units of production losses in the first quarter and 500,000 in the second quarter. Semiconductors are used more than ever before in new vehicles with electronic features such as Bluetooth connectivity and driver assist, navigation and hybrid electric systems. Stellantis achieved 1.3 billion euros in cost savings in the first half, mostly by sharing investments in new technologies and platforms, which Palmer said was a faster rate than initially forecast. It aims to achieve 80% of the targeted 5 billion in cost savings by 2024. “These synergies allow us to continue to invest in the electrification strategy, which we talk about every day,” Palmer said. Stellantis, which lags competitors in rolling out electric vehicles, plans to launch 21 fully electric or plug-in gas electric hybrid vehicles over the next two years. North American posted record profitability on global sales of Ram trucks and the strong launch of the Jeep Wrangler 4xe, which was the best-selling plug-in gas electric vehicle in the United States in the second quarter. Stellantis was the market leader in South America and second in Europe. The results were presented on a pro-forma basis, taking into account the performance of each of the carmakers as separate entities during 2020.
