An inside look at Mopar's SEMA fleet

Mopar is heading to the SEMA show in Las Vegas with a fleet of customized vehicles that appeal to enthusiasts of all stripes. There's a Dodge Viper ACR concept that follows in the lineage of the supercar's great road racing past, and a custom Ram ProMaster that might just be the ultimate outdoor party machine.
We got an inside look at Mopar's cars that will be on display at the show, which also include a Dodge Challenger T/A concept, two crazy Jeeps and a Ram 2500 Outdoorsman that could change the way you camp. While these are some of our favorites, Mopar is bringing plenty to SEMA, so let us know your top choices in the comments section.

Dirt Every Day tries to find the best 4x4 for under $4k

If you want to build a cheap truck that can still do dirty deeds off the beaten path, it's best to start with solid axles and a solid V8 engine. That sums up the lessons learned after watching the 2014 Cheap Truck Challenge from the Dirt Every Day video crew, who took to the deserts and surrounding areas near Reno, NV, in an attempt to find the best 4x4 for under $4,000. Fortunately for us, the whole sordid journey was captured on video.
This isn't the first time the boys from DED filmed a Cheap Truck Challenge, and this year's festivities pitted together a 1993 Chevy S10 pickup, a 1995 Jeep Grand Cherokee and a 1975 International truck in a series of challenges ranging from donuts to drag races, with plenty of hill-climbing and rock-crawling action in between. We don't want to spoil all the fun, but suffice it to say one competitor was found to be lacking while the other two performed (mostly) well. See for yourself in the video above.

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.
