FCA inline-six rumored to be real, headed for Jeep Wagoneer

In September, Allpar reported that that clues being dropped at Fiat- Chrysler headquarters, in the carmaker's factories, and on engineer resumes pointed to the development of an inline six-cylinder engine. The site has just proclaimed the rumor is reality, writing that the straight-six, "turbocharged to meet or beat 5.7 Hemi power ratings, with a smoother torque curve, is on the way." The motor's first outing is expected to be either the next-generation Jeep Grand Cherokee, debuting perhaps next year, or the Jeep Wagoneer, debuting in 2020 or 2021. "Tornado" is the purported codename for the power plant said to be just under three liters in displacement, expanding the family begun with the Global Medium Engine 2.0-liter turbo codenamed Hurricane. Engine bay constraints and a long use horizon mean engineers won't simply add two more cylinders to the GME, however. Allpar says the brief is to keep the Tornado GME-T6 — the alphanumeric for "turbocharged six" — no more than three inches longer than the Tigershark 2.4-liter four-cylinder. That means "major design changes" that could include a space-saving head, more closely spaced cylinders, and no cylinder liners. An FCA division called Comau could be called on for its "SmartSpray" plasma lining technology. Allpar muses that the standard version of the engine for Chrysler, Dodge, Jeep, and Ram could get a single twin-scroll turbocharger. Performance trims for Alfa Romeo and Maserati could get different heads and maybe twin turbos, an SRT version might also get both those tweaks. History shows that the Italian versions would make changes to the block, as well. Even so, the Tornado would be less expensive than any Ferrari-supplied V6. A straight-six would put FCA in company with current adopters BMW and Mercedes-Benz, future users like Jaguar, and perhaps Aston Martin. The engine would span the widest range of use cases in the U.S. carmaker's portfolio, though. Potential applications include being a base engine for Ram trucks, serving double duty as a base engine and 5.7-liter Hemi replacement for the Dodge Charger and Challenger, working in the high-end Jeeps, and as a properly hot trim — with Ferrari-designed heads — in the luxury Italian sports cars. The Alfa Romeo Giulia begs for just such motivation to fill the gap between the 280-hp, $42,695 Ti Sport RWD and the 505-hp, $73,700 Giulia Quadrifoglio RWD. And a twin-turbo inline-six in a Maserati Alfieri would stack up nicely with the Germans.

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).

2.1 million vehicles recalled again over faulty airbags

Fiat Chrysler Automobiles, Honda and Toyota will recall 2.1 million vehicles to fix faulty airbag modules "after the manufacturers' original attempts to fix the defects proved ineffective in some vehicles." These vehicles had all previously been recalled, but the National Highway Traffic Safety Administration found that the airbags could still potentially malfunction. This recall will cover Acura MDX, Dodge Viper, Jeep Grand Cherokee, Honda Odyssey, Pontiac Vibe, Toyota Corolla, Toyota Matrix and Toyota Avalon models made in the early 2000s. NHTSA has reportedly received about 40 reports of airbag deployment in such vehicles, even though the vehicle had not been involved in a crash. Roughly one million of these same vehicles, all from Honda and Toyota, are also subject to recalls due to faulty Takata airbag modules, though this particular recall is for "an electronic component manufactured by TRW" that is separate from the actual airbags from Takata. According to NHTSA Administrator Mark Rosekind: "This is unfortunately a complicated issue for consumers, who may have to return to their dealer more than once. But this is an urgent safety issue, and all consumers with vehicles covered by the previous recalls should have that remedy installed. Even though it's a temporary solution until the new remedy is available, they and their families will be safer if they take the time to learn if their vehicle is covered and follow their manufacturers' instructions. A hassle is much better than a family tragedy." If you're the owner of an affected car, expect to hear more from the official automaker and government channels in short order. In the meantime, we'd suggest getting your car checked and fixed at your local dealer. The official statement and recall information can be found below. Previously Recalled Vehicle Remedies Not Working as Designed; NHTSA Announces Follow up Recall of 2.12 Million Cars and SUVs Saturday, January 31, 2015 Contact: Gordon Trowbridge, 202-366-9550, Public.Affairs@dot.gov WASHINGTON – U.S. Transportation Secretary Anthony Foxx announced today the recall of more than 2.12 million Acura, Dodge, Jeep, Honda, Pontiac, and Toyota vehicles for a defect that may cause airbags to deploy inadvertently. The recalls will provide vehicle owners with a new remedy after the manufacturers' original attempts to fix the defects proved ineffective in some vehicles.
