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).

Autoblog fan favorite car ads from Super Bowl XLIX

Super Bowl XLIX is in the books, and the New England Patriots emerged victorious. Of course, if you're like us, the big game wasn't so much about the battle between the east coast and west, so much as a fight between the world's automotive advertisers. We collected and collated all of last night's new ads and put them together for you to vote on. And yes, we're limiting this year's contest to last night's new features. That's why you aren't seeing Dodge's epic Wisdom among our collection of commercials, and it's a similar story with Chevrolet's Truck Guy Focus Group series, which highlights the new Colorado. You can still vote for your favorites. We won't be closing the voting on our Super Bowl page, so while the winners and losers are correct as of this writing, it's entirely possible that there could be some changes in the rankings as time goes on. So, without any further ado, here are the winning ads based on your voting. Nissan: With Dad Fiat: Ready For Action Jeep: Beautiful Lands BMW: Newfangled Idea Mercedes-Benz: Fable NASCAR: America Start Your Engines As for those ads that failed to impact you, loyal readers, Toyota was the absolute, undisputed loser. The Japanese brand ran four ads in total – two for Toyota and two for Lexus – and all of them have negative tallies as of this writing. Lexus' Make Some Noise and Lets Play and Toyota's One Bold Choice and My Bold Dad both had very weak showings among the commercials that aired, although they weren't alone. Neither Mazda nor Kia scored particularly well, despite featuring celebrity magic act Penn and Teller and former James Bond, Pierce Brosnan, respectively. Chevrolet was the winner of the losers, as of our writing, recording the fewest downvotes for its audience-punking The Big Game ad. If you want to take a second look at the losing ads, you can head back to our Super Bowl page for the complete collection. But for now, head into Comments and let us know what you think of the results.

'84 MotorWeek Cherokee, Bronco and Blazer comparison indulges your SUV nostalgia

These days, truck-based, full-frame SUVs are somewhat of a rarity on the auto landscape due to the rapid rise in popularity of easier-driving, car-based crossovers. Although, without the gradually building popularity of these chunky, high-riding vehicles decades ago, it's unlikely that America's roads would be filled with so many CUVs today. In its latest dig into the archives, MotorWeek has found a 1984 comparison test of a trio of these early Sport Utility Wagons, as long-time host John Davis called them, that helped get acceptance of this segment going. This is a red, white and blue test of the SUVs from American automakers at the time and pits the Chevrolet Blazer, Ford Bronco and Jeep Cherokee (specifically in Wagoneer guise) against each other. Driving manners and interior usability are considered in the evaluation, but Motorweek actually takes these vehicles off road, too. Among the bigger revelations is the improvement in on-road ability in the past 30 years. While specific 0-60 times aren't given, all three models take around 10 seconds just to get to around 50 miles per hour in the 500-feet on-ramp acceleration test. Check out this clip to see just how far this segment has progressed in the past three decades or just get a blast of nostalgia from these now vintage models.
