According to the latest reports from Kicking Tires, it appears that Chrysler will introduce on the 2012 Jeep Wrangler and Wrangler Unlimited its brand new 3.6-liter V6 powertrain.

Dubbed Pentastar V6, the new engine made its debut on the 2011 Jeep Grand Cherokee, but now is also featured on almost all the models from Chrysler’s lineup, such as the 2011 Dodge Charger, 2011 Journey, 2011 Grand Caravan but also on the 2011 Dodge Durango.

Still, the bad news is that the 2011 Jeep Wrangler will get the old 3.8-liter V6 delivering just 202 hp.

Furthermore, Sergio Marchionne, CEO of Chrysler Group, also confirmed the upcoming Dodge small car. According to Marchionne, the new car will come in a sedan form, and not as a hatchback like the 2011 Caliber, because hatchback are not so popular in America.

The new car will be based on Fiat’s new compact platform, used by the new Alfa Romeo Giulietta.

Same architecture used by the new car will also govern of Chrysler’s C- and D-segment vehicles, both passenger cars and SUVs, for the foreseeable future. The new Dodge sedan will make its debut in 2012, and will be produced at the Belvidere, Ill., Assembly Plant.

Building on the brand’s over 70 years of 4x4 experience and expertise, the Jeep Wrangler is made to deliver superb off-the-road capability. This extraordinary ability of the new Jeep Wrangler is made possible with its body-on-frame design as well as front and rear five-link suspension system. Moreover, the new Jeep Wrangler makes use of live axles and electronic lockers, as well as dynamic six-speed manual and five-speed automatic transmissions.

For the latest version of the Wrangler, engineers at Jeep painstakingly worked to optimize its body-on-frame design ride and sound attributes. These were complemented by new motors and transmissions as well as further suspension calibrations.

Moreover, engineers worked to refine the powertrain mounting system and firewall noise damping, resulting to better cabin audio quality. These refinements were also helped by the fact that the new Wrangler now comes with an cover that could isolate the interior from noises coming from the engine and the road.

Likewise, the engine noise could hardly be heard even when outside the new Wrangler. This is because, all engine accessories – like the power steering pump, air conditioning compressor and alternator – are now mounted securely to the new 3.6-liter V-6 engine using no brackets -- making them less prone to vibration and noise. In addition, engineers also retuned the SUV’s shocks to achieve an optimal balance between on-the-road stability and off-the-road capability.
