Jeep Comanche Moab Concept: Hell yeah!

The moment I saw the Jeep Renegade I knew it was a winner, at least in terms of styling. The Renegade's "face" is exactly what small 21st-century Jeeps should look like. It has loads of Jeep's visual heritage DNA – important! – that has been brought up-to-date in the best possible way. (Now if only they could graft that face on to the new-ish Cherokee...). Where the Renegade falls short is what's under the skin. Thanks to misguided marketing, it is saddled with a rather unremarkable USA-spec 2.4L four, undersized tires, so-so ground clearance, an iffy 9-speed automatic, and a questionable (available) low range. I don't mind the independent suspension; in fact I embrace it, as IFS/IRS is the future in terms of off-road suspension design. So, for me, the Renegade is a close-but-no-cigar vehicle, at least as it currently stands. This new Comanche, however, shows how the Renegade can evolve; both as a 4-door SUV, and in terms of how spin-off models can be developed. Big beefy tires, flared out fenders, and great ground clearance are the main ingredients that make this work visually. Still wish for a 3.6L V6 under the hood, but the 2.0L diesel isn't a bad alternative. Anyway, I think a Comanche pickup makes more sense than the predicted Wrangler-based pickup. Why? I'm not big on retro-vehicles in general. Rarely do they survive long term. Besides, the Comanche would be far more civilized and livable. I could see this Comanche pickup as a daily driver much more so than a Wrangler-based pickup. Yeah, I like and value creature comforts over ultimate off-road ability. I think most pickup buyers would agree. Finally, while there is a large devoted Wrangler following who would love a Wrangler-based pickup, I bet this Renegade-based Comanche would bring more new customers into the Jeep tent – especially over a much wider age demographic.

FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.

Jeep rocks the Wrangler Red Rock concept in Vegas [w/video]

The SEMA show may have once been all about dropping rides to the floor, but these days it's at least as much about jacking them up on lifted suspensions. And few show cars – or trucks, we should say – managed to embody that spirit at this year's tuner exposition quite as well as the Jeep Wrangler Red Rock you see here. The concept started out life as a Wrangler Unlimited, but instead of four doors, it has none. Or any roof, for that matter. Just a roll cage and a windscreen. What it does have are 17-inch wheels wearing 35-inch BF Goodrich tires and fitted to a suspension lifted by two inches. It also has a reinforced tailgate, power winch, tow hooks... everything, in short, that you could want or need for off-roading, and little more. As you can see, it also looks the business, with a custom hood, body-color grille, matte-finish bumpers, and a brown leather interior. Handsome as it is, though, its rugged beauty runs more than skin deep: lift off the sheetmetal and you'd find electronic locking differentials, a transfer case, and solid axles fore and aft. A more extreme take on the existing Jeep Wrangler Unlimited Rubicon Hard Rock edition, the Red Rock show truck was done up to honor the organization behind the Easter Jeep Safari that's a favorite among the legions of the Jeep faithful. And while it remains a concept only for the time being, a production version is slated to follow in time to celebrate the event's 50th anniversary next year. Related Video:
