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.

These cars are headed to the Great Crusher In The Sky

It happens every year. We bid adieu to some cars and trucks that will be missed, and say good riddance to others wondering how they stayed around so long. Whether they're being killed off for slow sales or due to a new product coming along to replace them, the list of vehicles being discontinued after 2012 is surprisingly long and diverse.
CNN Money has compiled a list of departing vehicles, to which we've added a few more of our own. In the slow sales column, cars like the Lexus HS 250h, Mercedes-Benz R-Class and the full Maybach lineup appear, while the Ford Escape Hybrid, Mazda CX-7 and Hyundai Veracruz are all having their gaps filled with more modern and more fuel-efficient alternatives. Obvious exceptions to the rule include models that still sell in decent numbers like the Jeep Liberty and the Chrysler Town & Country (which will eventually be replaced by a crossover-like vehicle).

2014 Jeep Cherokee: Introduction

When we look back at some of the more shocking product launches of recent yeras, the Jeep Cherokee is certainly high up on the list. And we aren't just talking about its off-the-wall, polarizing design.
For starters, it brought back the iconic Cherokee nameplate - something Jeep enthusiasts have coveted for ages. But beyond that, it brought a new evolution for the Jeep brand. After all, the Cherokee is car-based - using the same compact platform that underpins the Dodge Dart and Chrysler 200. It has a greater focus on technology and refinement than ever before, in an effort to appeal to a new crop of Jeep customers. And powering it all is a new (optional) V6 engine paired with an equally new nine-speed automatic transmission.
Can the Cherokee's car-based roots still allow for a vehicle that's superb when the going gets tough? Will its design still be a love/hate affair in one year's time, or will it start to blend in? Is the powertrain strong enough to not only support the needs of daily driving and road trips, but blaze a few trails as well? We're aiming to answer all these questions, and more, over the next 12 months. Welcome to the Autoblog long-term garage, Cherokee.
