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 Trailhawk [w/video]

There are two avenues to the world of off-roading. Arguably the more popular is to pick up a second- or third-hand Jeep, Land Rover or pickup truck and go wild with the aftermarket. The opposite approach, though, is to simply buy new, which brings a warranty along with the most up-to-date off-road tech fitted by the factory (despite likely lacking the ultimate capability of an aftermarket-imbued vehicle). That second option has, traditionally, been pricey. Take our long-term Jeep Cherokee Trailhawk, which rings up at just over $38,000. A Ford F-150 SVT Raptor is going to be an even more expensive proposition, while the undisputed kings of luxury off-road performance from the factory – the Range Rover, Toyota Land Cruiser and Mercedes-Benz G-Wagen – will require ownership of a medium-sized oil well. With all due respect to those who take their Trail-Rated Jeep Patriot models off-road, the all-new Renegade Trailhawk is such an exciting proposition because it brings the cost of a warranty-backed off-roader down significantly, while also delivering a degree of trail-rated performance that should easily fulfill the needs of the average enthusiast. Drive Notes Before we get into what it adds, it's worth noting that the Trailhawk trim does have a small impact on the Renegade's on-road abilities. As we said in our original feature, the TH adds a significant amount of weight to the standard CUV, as it tips the scales at nearly 3,600 pounds. That mass, combined with the slightly higher stance, means the off-road model doesn't handle quite as well as a lesser Jeep. It also doesn't feel as fleet of foot, as it retains the same 2.4-liter, 180-horsepower four-cylinder and nine-speed automatic found throughout the Renegade range. Despite the downers, the Trailhawk trim does bring quite a lot to the Renegade package, most notably in the form of a bespoke version of Jeep's Active Drive all-wheel-drive system. The upgraded system features a dedicated 20:1 crawl ratio while the Selec-Terrain system is home to a new Rock setting. Beyond that, Jeep lifted the Renegade's ride height eight-tenths of an inch, increasing overall ground clearance to 8.7 inches and delivering 8.1 inches of wheel articulation. This is complemented by unique front- and rear-fascias, which up the approach and departure angles to 30.5 and 34.3 degrees, respectively, besting the Cherokee Trailhawk's 29.8 degrees and 32.1 degrees.

Chrysler expecting up to 200,000 9-speed transmissions for 3 models this year

Striving for improved fuel economy, we already knew that Chrysler will begin using a nine-speed automatic transmission in some of its new products this year, but what we haven't known is that volume at which this gearbox will be used. According to Bloomberg, Chrysler CEO Sergio Marchionne has been quoted as saying that the automaker expects to sell close to 200,000 units equipped with this new transmission in 2013. Those gear-rich trannies will be spread out across three models, consisting of the redesigned Chrysler 200, the still-unnamed Jeep Liberty replacement and the Dodge Dart.
This transmission should play a pivotal role in making Chrysler vehicles more competitive in their respective segments. Just for comparison, one of the Dart's key competitors, the Toyota Corolla, still uses a four-speed automatic, and a previous report indicates that the next-generation 200 could get up to 38 miles per gallon on the highway, which is better than most non-hybrid midsize sedans on the market. Marchionne says that the new Jeep model is expected during the second quarter of this year, but there is no word as to when the new 200 or nine-speed Dart will debut, but clearly Dodge would like to have the transmission in its compact yesterday. As for that volume figure, it definitely doesn't seem out of reach since the Dart, Liberty and 200 combined for a total of more than 225,000 units in 2012.
How many more gears can we expect in future cars? Probably not many more, since the CEO of transmission-builder ZF, Stefan Sommer, previously stated that nine speeds was the "natural limit" for transmissions.
