Jeep gives a trio of customs an encore showing at SEMA

While Jeep certainly had some new customs on display at this year's SEMA show, it wasn't afraid to recycle a few that people might have missed from earlier this year. The maker of many beloved off-roaders already displayed the Jeep Cherokee Dakar, Maximum Performance Wrangler and Wrangler Mojo at the 2014 Easter Safari, but they all made it to SEMA for an encore.
Based around the Trailhawk, the Cherokee Dakar (pictured above) imagines an even more off-road-capable version of the crossover. The concept wears a mix of Silver Steel Stain paint with Flame Red graphics and rides on 17-inch wheels wrapped in 33-inch BFGoodrich Mud Terrain tires. To back up the rugged look, the Dakar is fitted with rock rails and skid plates protecting the oil pan, front suspension, fuel tank and other underbody parts. It also sports prototype parts from Jeep Performance Parts, including a lift kit and fender flares.
The Wrangler is one of the paragons of off-roading, and as the name suggests, the Maximum Performance Wrangler concept is meant to be the ultimate example of what it can do. The custom features locking Dana 60 axles front and rear, a 4:1 Rock-Trac transfer case, prototype 4-inch lift kit and 37-inch Mud Terrain tires over beadlock wheels. To stay on the trails well into the night, a bar of LEDs is mounted above the windshield. And finally, the Mopar Blue exterior kind of makes the vehicle look like the world's toughest blueberry.

How to tune a car right: Part 3, tuning Mopar with OST Dyno

Not long ago, I wrote a story about a pony car tuned with a supercharger. The blower install had been done properly. Then the car's owner bolted on a set of great looking wheels wrapped in good looking but inexpensive rubber. On my first test drive, I couldn't get any of that supercharged sweetness to the ground. It was the perfect ride for parking in a Burger King parking lot on a Friday night. I tooled around on a Sunday drive, shaking my head that someone had spent five figures to get more power the right way, with a clean install, then wiped out the gains so thoroughly that the stock engine would likely have overwhelmed the tires. This got me thinking about the ways people ruin their quest for horsepower, either on the front end by not insisting on a clean install and paying the money for it, or on the back end with supplemental purchases like cheap tires or cheap gas. So I called three tuners, one focused on GM, one on Mopar, one on Ford, to find out what people should know about how to get the best power for their goals, and how to make sure they are able to use all that power. The first interview in this three-part series was with Blake Leonard at Top Speed Cincy in Cincinnati, Ohio, the second with Brandon Alsept at BA Motorsports in Milford, Ohio. This third and last interview is with Micah Doban at OST Dyno in Slippery Rock, Pennsylvania, a family business with more than 40 years of Mopar expertise specializing in Gen III Hemis, but tuning everything from land-speed cars and drag racers to Jeeps The interview has been edited for clarity and concision. Do people who come to OST generally know what they want? Probably 80% of the people who come in simply want more power with no particular ET goal [ET is a kind of bracket handicapped drag racing – ed.]. WhatÂ’s the best way to start a Mopar tune? The first thing is what people often skip, and that's to find a tuner or a shop. People will throw parts on their cars that the Internet said to, then go to a tuner who does things a different way, and [the tuner is] like ‘No we don't like to use these injectors, we don't like these parts.Â’ You have to find someone familiar with the parts that are on your car or that you're planning to put on your car. So having a goal and then finding a tuner who can help you with that goal is proper way to start. Exactly. And a lot of tuners have their own formula – and when I say tuner I mean someone that also does work to the cars.

Jeep Wrangler diesel likely after 2015 model refresh

We automotive journalists aren't always the right people to ask about whether a US-spec vehicle should or should not be offered with a diesel powertrain (hint: the answer is usually "YES"). But when it comes to the iconic, off-road-ready Jeep Wrangler, we aren't the only ones who have been clamoring for an oil-burning engine behind that famous seven-slat grille. To that end, it appears there's good news on the horizon, as Jeep CEO Mike Manley recently told Ward's Auto that the "Wrangler is on the radar to get (a) diesel."
"I'm confident that the Grand Cherokee will show just how large a demand there is for diesel, and I think what that will do is reinforce the need for us to target Wrangler as a vehicle that can take a diesel," Manley told Ward's. The most rugged of Jeeps is scheduled to get an overhaul around 2015-16, and the diesel powertrain will likely be introduced around that time.
This year alone, Chrysler will be adding a diesel engine to the Grand Cherokee SUV, as well as the Ram 1500 pickup and Promaster utility van.
