FCA's Pentastar V6 Could Soon Make Way For A Turbocharged I6

Fiat Chrysler brands including Jeep and Chrysler could be about to ditch the long-serving and respected Pentastar V6 in favour of something new
FCA's Pentastar V6 Could Soon Make Way For A Turbocharged I6

Fiat Chrysler Automobiles (FCA) is planning to retire the ubiquitous Pentastar V6 in favour of a new straight-six with turbocharging.

The Pentastar engine, first released in 2010 to feature in Jeeps, Dodges and Chryslers, has since seen service in everything from the Wrangler to the Dodge Charger. Built in 3.0-, 3.2- and 3.6-litre capacities with up to 305bhp, it’s something of a modern institution.

But, according to a report on the FCA enthusiast website Allpar.com, a new inline-six is being developed that could fill an even broader remit than the Pentastar does. With turbocharging it will match or better the 5.7-litre Hemi V8 for power and torque, be vastly more fuel-efficient and even compact enough to slot into almost any FCA platform.

The target, says the report, is to make the engine just three inches longer – at most – than FCA’s current 2.4-litre four-pot. That will involve counting every millimetre and swapping old-school steel cylinder linings for thinner hardened aluminium, for example. It could also go comparatively long on stroke but narrow on bore, to help shorten the block.

And yet it won’t be a small-capacity engine. Coming in below three litres will bring tax advantages in certain markets around the world while maintaining enough volume to generate big power outputs. Turbocharging could be supplied by either a single twin-scroll snail or twin items in FCA’s more serious performance cars.

The first car likely to get the new engine is the Jeep Wagoneer or, if not that, the next Cherokee. Both would benefit from the natural balance and smooth torque of a turbocharged straight-six – and they would soon be joined by dozens of others.

This is good news. Inline-6 engines are a million times better than V6s.

Just a small error MattKimberley

The subtitle says “Jeep and Chevrolet” but I think you meant Chrysler…

An inline-six in a Jeep would be pretty cool with a manual transmission

You mean like they had from 1987 to 2006 in virtually every model?? The Jeep 4.0 straight six…

Performance straight sixes are something America has never really taken a crack at. Back in 1967, Pontiac nearly did however. They put some real effort into their base-model 4.1l straight six and well… from what I understand, those who bought it loved it. The thing that made them special was that they came from the showroom with a single overhead cam in 1967! They made 215hp at 5200rpm which even today is respectable. So I guess the big three have always known how to make a performance straight six but… People don’t know how to buy them.

This is awesome news. America has always had bigger engines so while everyone is forced to downsize they’ll be going from eight to six instead of six to four.

And for a moment I thought straight sixes were on the way out. I’m happy they’re making a return

Wasn’t the Penstar V6 like one of the Worst Engines ever made? Behind the Cadillac V8 6-4 and those old early 3cyls?

Reminds me of my old Jeep with the good ol’ 4.0. Had the most torque of anything I’ve owned save for my F-150 and diesel VW.

That’s what I thought with small bore and long stroke.
