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.

2015 Jeep Renegade

It's no secret that the midsize crossover segment is one of the most hotly contested battlegrounds in the automotive industry. Long have vehicles like the Ford Escape, Honda CR-V and Toyota RAV4 duked it out for those ever illusive consumer dollars. For many customers, though, even something like a Nissan Rogue is too big, whether in terms of price, fuel economy or just plain size.
For those customers, a growing market segment seems poised to fulfill their needs. Compact crossovers and tall wagons like the Nissan Juke and Kia Soul offer the high-riding driving experience with all the utility that comes from their two-box layout. It's an underrepresented segment among manufacturers, with big names like Toyota, Ford, General Motors and Honda lacking a true competitor.
To capitalize on this growing class, Chrysler's Jeep brand has readied this: the Renegade. That's right. Not Jeepster - Renegade. This diminutive off-roader, which rides on Fiat Chrysler's new small-wide 4x4 architecture, represents Jeep's first foray into the subcompact CUV segment as we know it, and it's making its official debut this week, on the floor of the 2014 Geneva Motor Show. Join us as we take a close look at one of Jeep's most important products in some time.

2014 Jeep Compass/Patriot sing their swan songs with a six-speed automatic

Unless the governor, Fiat CEO Sergio Marchionne, gives them a reprieve, the 2014 Jeep Compass and Patriot are expected to meet their makers sometime next year. Should they perish, it's a shame that it would happen just as they've shed the continuously variable transmission that was their major bugbear, and just as the Compass has gotten its best looks yet.
Both will roll with a proper six-speed automatic transmission, courtesy of PowerTech. Noise-resistant gears and tuning by Chrysler boffins should alleviate the unappealing sounds that were given off by the older CVT. Unless, that is, you choose to have either model equipped with Freedom Drive II; the serious off-road package, available on both baby Jeeps, will still come with the CVT. The base transmission on the entry-level Sport trim remains the five-speed manual.
Otherwise, it's minor changes for the Compass, set off by the new 18-inch wheel option, trim pieces around the car and a back-up camera. The Patriot gets seat-mounted airbags, but is carryover otherwise. With their expected demises perhaps a year away, not much has changed otherwise. Engine choices comprise the 2.0-liter four-cylinder with 158 horsepower and 141 pound-feet of torque or the 2.4-liter four-cylinder with 172 hp and 165 lb-ft.
