Chrysler Pentastar V-6s to get turbos and direct injection, sources say

DETROIT -- Chrysler Group is improving its Pentastar family of V-6s, adding direct injection, turbocharging and other technology to enable smaller displacement engines to power its vehicles.

The Pentastar Upgrade -- or PUG for short -- is part of a strategy to meet tightening corporate average fuel economy standards. Sources say the improvements will boost output and increase fuel economy on the V-6 engines that power most Chrysler vehicles.

Also possible as part of the improvements: the potential for turbocharging what are now naturally aspirated engines. Meanwhile, Fiat's MultiAir variable valve timing technology will remain, sources say.

The first improved 3.6-liter V-6 is scheduled to debut in late 2015 as part of a freshening of the Jeep Grand Cherokee, sources say. A Chrysler spokesman declined to comment on the Pentastar Upgrade project.

Another example will be the redesigned Chrysler Town & Country minivan, due in 2016. Chrysler sources say the new minivan will be powered by an improved 3.2-liter V-6 instead of its current 3.6-liter V-6.

The improved 3.2-liter V-6 will be combined with a nine-speed automatic transmission, as it is in some versions of the 2015 Jeep Cherokee. The powertrain combination, better aerodynamics and weight reductions are expected to boost the minivan's fuel economy at least 25 percent over its current EPA fuel economy rating of 17 mpg city/25 highway, the sources said.

The naturally aspirated 3.6-liter Pentastar V-6 was introduced in 2010 on the 2011 Jeep Grand Cherokee. Chrysler Group has spread the 3.6-liter across most of its lineup, including its top-selling products such as the Ram 1500 and Jeep Grand Cherokee and Wrangler.

Depending on the added efficiency engineers are able to achieve, the improved 3.6-liter engine could help the Ram 1500 regain the gasoline-powered fuel efficiency crown it lost last month to a turbocharged version of the 2015 Ford F-150.

Su Allpar si parla insistemente di aggiornamento del Pentastar (nome in codice PUG che sta per Pentastar UpGrade) con una nuova testa che prevede delle valvole per migliorare la turbolenza a bassi regimi. Qualcuno ha altre novità? Si parla anche di iniezione diretta, ma anche per tale motivo il motore è un pò in stand-by finché non sia utilizzata ovunque la benzina con bassissimo contenuto di solfuro.

Non riesco bene a capire questo pezzo... cosa vuol dire che il Multiair rimarrà? Che non lo mettono ancora?

Pentastar upgrade for 2016 revealed

Chrysler has revealed the upgrades to the Pentastar V6 engine for 2016. They are not earth-shattering, and do not include direct injection; but they do strengthen an already highly competitive engine. In essence, the V6 has been lightened, retuned, and made both more fuel-efficient and more powerful.

Numerous steps were taken to cut pumping losses and internal friction, including switching to a new two-stage valve lift control setup (low valve lift for efficiency at normal speeds, and high lift for power when needed), using a new low-friction coating, and changing the valve timing system.

Changing components made the engine lighter, despite additional features. A different manifold boosted torque in the under-3,000-rpm range, where it spends most of its time for most people, and higher compression and other tuning increased horsepower by five in the Jeep Grand Cherokee, the only 2016 car to get it so far. See our Pentastar Upgrade page for more detail.

Direct injection is still rumored to be on the way, awaiting low-sulfur gasoline mandates in the United States.

Magari ho capito io male, ma non si dice solo che la produzione del V6 verrà concentrata nell'edificio Sud di Trenton, e che la fabbrica nord verrà riutilizzata diversamente?

Immagino produrranno motori elettrici o altri componenti credo
