It was reported in AutoGuide and allpar that Dodge has a direct-injection 420 hp twin-turbo 3.0 Pentastar engine scheduled for 2014 (also a 370 hp single turbo version). Could this be the engine that replaces the Hemi?

Autoguide:

A company doesn’t usually send out a press release to announce production of a new engine, but these days Chrysler can use all the good press it can get. And good press this most certainly is, as the new Pentastar 3.6-liter V6 marks the first real step in the rebirth of Chrysler.

The new V6 engine will significantly reduce overall costs as Chrysler will replace seven different V6 engines currently used across the company’s lineup with this one motor. Chrysler also claims it will reduce fuel consumption by at least 25 percent. Power output will also increase considerably, with 280-hp and 260 ft-lbs of torque available from the V6 when it debuts later this year in the new 2011 Jeep Grand Cherokee.

Afterwards, it’s slated to arrive in the new mid-size D-Class models, mated to a six-speed Dual Dry Clutch Transmission (DDCT).

But the best news of all is confirmation that Chrysler has built the engine to be compatible with more advanced technologies, meaning that in the future it will get Fiat’s Multiair variable valve timing, direct-injection and turbocharging.

Previously it was thought this technology might only be used in pricey European models (Alfa Romeo perhaps?), but the fact that Chrysler thought to mention it speaks volumes. Perhaps, the company is looking to follow after Ford’s EcoBoost plan and bring a Turbo Pentastar V6 to market as a V8 alternative?"
