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).

FCA tries to block sale of Mahindra Roxor, says it's too Jeep-like

This week, FCA filed a complaint intended to stop the sale of the new Mahindra Roxor, claiming the Indian-built off-roader looks too much like a Jeep, particularly the original Willys Jeep from the 1940s. Automotive News reports that FCA is worried about both the Roxor's design and the undercutting of Jeep Wrangler sales with a new, foreign-built model. Late last year, Mumbai-based automaker Mahindra & Mahindra announced it was investing $600 million in a production facility in metro Detroit. It's actually just miles from FCA's corporate headquarters in Auburn Hills. Mahindra & Mahindra plans to start selling EVs in the U.S. and has been spied testing prototype vehicles for the U.S. Postal Service. Roxors are built in India, with the parts shipped to the U.S. for final assembly. The new diesel-powered Roxor isn't road-legal in the U.S. because of safety and emissions regulations. It has a top speed of just 45 mph, so it won't be competing with the Wrangler when it comes to mass-market sales. That said, FCA has a point when it comes to the looks — though years ago, Mahindra actually licensed the design for the original Jeep. It's unclear where that license currently stands.

In Michigan, car hackers could face life imprisonment

Car hackers may not want to mess with vehicles in and around the Motor City. A pair of Michigan lawmakers introduced legislation Thursday that would punish anyone who infiltrates a vehicle's electronic systems with penalties as harsh as life imprisonment. Senate bill 927 says that "a person shall not intentionally access or cause access to be made to an electronic system of a motor vehicle to willfully destroy, damage, impair, alter or gain unauthorized control of the motor vehicle." Offenders will be deemed guilty of a felony, and may be imprisoned for any number of years up to life in prison. The proposed legislation is one of the first attempts nationally to address the consequences for car hacking, which has become a top concern throughout the auto industry. Critics have accused executives of being slow to respond to the threats, which were first known as long as six years ago but gained attention last July when a pair of researchers remotely controlled a Jeep Cherokee. In January, the industry established an Information Sharing and Analysis Center to collectively evaluate security measures and counter breaches. But the Michigan bill isn't noteworthy only because of the life penalty prescribed; it's noteworthy for what's missing in its details. Language in the bill doesn't delineate between independent cyber-security researchers and criminals who intend to inflict harm or havoc. Under its provisions, it's possible Charlie Miller, pictured below, and Chris Valasek, the researchers who demonstrated last summer that the Cherokee could be remotely commandeered and controlled, could face life behind bars. Provisions of the legislation that prevent a person from "altering" the motor vehicle could ensnare car enthusiasts or gearheads who tinker with electronic systems to boost performance, increase fuel efficiency or add aftermarket features. In that context, Senate Bill 927 seems like the latest measure in a running feud between independent researchers, gearheads and big automakers. Car companies don't like third parties poking around their electronic systems and would prefer the researchers not reveal security weaknesses. Researchers, on the other hand, say many carmakers are either slow to fix or unwilling to repair security holes unless they're able to publish their findings.
