2014 Jeep Patriot and Compass ditch CVT for six-speed auto

It was reported in Automotive News a few months ago, but a new report on Allpar.com adds some details to news that the 2014 Jeep Compass and Patriot will get a six-speed automatic to replace the CVTs they currently use. According to a tip provided to Allpar, the 2014 models will begin production in March and be on sale sometime in the summer. The Jatco-sourced CVT in use until now - Jatco is owned by Nissan and Mitsubishi - has been often criticized, and many won't be sad to see it go.
The incoming six-speed automatic is said to be an all-wheel-drive cog-swapper that's the work of Hyundai and Magna and has been paired with the DynaMax AWD system used in the Hyundai ix35 and Kia Sportage. It won't be the only Chrysler product using a transmission with ties to Hyundai: the six-speed automatic in the Dodge Dart comes from Powertech, which is a wholly-owned subsidiary of Hyundai. With the Patriot and Compass said to be driving down the trail for the last time this year, it will be a short run for the new tranny and the rumored addition of a backup camera and power rear liftgate on the Compass.

Some Jeep Cherokees and Chrysler 200s to get standard stop-start in 2015

Automakers the world over are striving to find ways to make their models more efficient, and Chrysler has a solution for some versions of the 2015 Chrysler 200 and 2015 Jeep Cherokee (2014 model shown). The Tigershark 2.4-liter four-cylinder in the 200 and the 3.2-liter Pentastar V6 in the Cherokee are getting a slight boost later this year thanks to the addition of Chrysler's Engine Stop-Start system as standard equipment. The company predicts modest gains - a three-percent improvement in fuel economy and a three percent reduction in CO2 emissions with the new tech compared to without it. While it's not much, those who sit in traffic a lot may see a difference.
Chrysler's stop/start system uses a high-speed starter motor to restart the vehicle in a claimed a third of a second. It works by detecting when the vehicle comes to a stop and turning off the engine. A more powerful battery maintains all of the model's accessories while it sits. When the driver lets off the brake, the car starts up again to drive away. There is even a button in the cabin to turn the ESS off, if desired.
The Jeep will be the first to receive ESS in the third quarter of this year to coincide with the start of production of the 2015 model-year version. The 200 will follow in the fourth quarter as a rolling change in production.

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.
