Chrysler Reportedly Adding Pentastar V-6 to 2012 Jeep Wrangler, Ram 1500
Additional power and reduced fuel consumption are apparently in the cards for the 2012 Jeep Wrangler and 2012 Ram 1500. New reports say that Chrysler will continue its rollout of the 3.6-liter Pentastar V-6 by installing it in Jeep’s off-roader and the base Ram truck for the new model year.
Chrysler's steady rollout of the lauded Pentastar V-6 engine will apparently continue with both the 2012 Jeep Wrangler and 2012 Ram 1500. According to new reports, the new 3.6-liter engine will soon serve as the base V-6 engine offering in bothJeep's iconic off-roader and the base Ram truck.
The news is hardly surprising, seeing as Chrysler has aggressively replaced outmoded engines with the new Pentastar across its lineup; in fact, the company claims the Pentastar will account for more than one-third of its engine volume by 2014. We believed the special Wrangler Mojave model served as a swan song of sorts for the outgoing 3.8-liter V-6 before the model scored the Pentastar mill, and it was expected that the Ram 1500 would gain more power in response to the new V-6 engines available in the Ford F-150.
The Toledo Blade reports that Pentastar bound for the 2012 Wrangler will be rated at the same 290 hp and 260 lb-ft of torque as that found in the 2011 Grand Cherokee. That's a much-needed dose of power for the Wrangler, which currently struggles with a minivan-sourced 3.8-liter V-6, which produces just 202 hp and 237 lb-ft of torque. A five-speed automatic transmission allegedly replaces the Wrangler's current four-speed automatic. The Blade suggests 2012 Wrangler fuel economy could climb to 16/23 mpg (city/highway), whereas the 2011 model is EPA-rated at 15/19 mpg.
It also appears that the Pentastar will find its way under the hood of the Ram 1500 pickup truck, according to Ward's Auto. Switching the old base engine -- a 3.7-liter V-6 good for 215 hp and 235 lb-ft -- for the new 3.6-liter V-6 should imbue the Ram with more performance and mildly improved fuel economy. The current V-6, only offered in rear-drive trucks, returns an EPA-estimated 14/20 mpg (city/highway.)
The all-aluminum, 3.6-liter Pentastar V-6 made its production debut in the 2011 Jeep Grand Cherokee. It is more fuel-efficient and more powerful than the outgoing Chrysler V-6 engines it replaces. Headlining technologies include variable valve timing, lightweight integrated exhaust manifolds, and a 10.2:1 compression ratio. In the future, it's rumored that the engine may be upgraded with turbocharging, direct injection, or a variant of Fiat's MultiAir system.
When Chrysler first introduced the Pentastar in 2010, officials asserted that replacing dated V-6 engines with the new Pentastar would raise the company's Corporate Average Fuel Economy (CAFE) rating by two mpg. More power and improved fuel economy? Sounds like a win-win to us.
