Watch this 650-hp Hennessey Jeep Grand Cherokee go from 0-60 in 3.9 seconds

Hennessey Performance Engineering has created an HPE650 package for the Jeep Grand Cherokee SRT fitted with the 6.4-liter Hemi engine. When it leaves the showroom floor it has 470 horsepower and gets from 0-60 miles per hour in 4.8 seconds. When it leaves Hennessey's garage floor after the upgrade it has 650 horsepower - 530 hp at the wheels, according to Hennessey - and gets to 60 mph in 3.9 seconds on its way to running the quarter-mile in 12.6 seconds.
There's more than just a Roots-type supercharger bolt-on, with ported cylinder heads and high-flow headers among the many changes made to the engine. You can watch this pre-2014 facelift silver model prove its spec sheet on the drag strip in the video below.

New Barracuda, Grand Cherokee Trackhawk coming soon

As we write this, Fiat Chrysler Automobiles is conducting a major dealership event in sunny Las Vegas. New vehicles are being announced, redesigned offerings are being teased, and promises are being made to the sprawling company's dealer body. And, as all these announcements are meant to be tip-top secret, they're leaking out left, right, and center. Naturally. FCA is telling its dealers all of the vehicles shown at the Vegas gala will be in showrooms within 12 to 24 months, and that the product offensive will include at least 30 new or significantly refreshed models. Some of those we've known about since FCA boss Sergio Marchionne unveiled his highly ambitious five-year plan in May 2014, while we're hearing about others for the very first time. We've reached out to our sources within FCA, and will update this post as we learn more. It should be noted that while we've tried to rely on concrete sources or corroborations from multiple sources, some of the news here comes from people claiming to have been in attendance and posting in forums like Allpar and Jalopnik's Opposite Lock. Unless corroborated by a mainstream source or confirmed by our own sources within FCA, we're listing each item that comes from a forum. Have those grains of salt at the ready. Chrysler Dodge Durango-sized SUV with stow-and-go was shown. A poster on Allpar Forums claims it had a Durango's interior. New Aspen? Town and Country PHEV confirmed (again). A plug-in minivan was originally announced as part of five-year plan. No news on 200 or 300. Dodge The redesigned Charger will use the Alfa Romeo Giulia's rear-drive platform and, according Automotive News, draw inspiration from 1999's Charger concept car. We're wagering the 24-month time frame specified to dealers will move the new sedan's arrival up from 2018 to mid-2017. Jalopnik's Opposite Lock claims two new Challenger models are coming. Challenger ADR (American Drag Racer) and T/A. ADR should appeal to bracket racers and is more powerful than the SRT Hellcat, while T/A is for track rats, just like Viper T/A. Automotive News claims the legendary Barracuda nameplate will be revived as a Dodge. The Barracuda will be smaller than Challenger, offered as both a coupe and a convertible. Allpar claims it will feature modern styling. A Dodge Durango SRT was announced with 6.4-liter Hemi V8 and rear-drive. Sources within FCA confirmed its arrival with Autoblog. Apparently, dealers were shown an example in B5 Blue.

'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.
