The in-line 6-cylinder engine you'll never see from Alfa Romeo

If one thing is certain, it's that the development of new combustion engines is well underway at Stellantis. This is due to the law that will ban the sale of cars equipped with these engines by 2035 in many European countries.

And that's a shame, because the internal combustion engine, a true feat of engineering, still had a lot to show. Proof with the GME T6, an in-line 6-cylinder created by FCA before the merger with PSA, which could have been installed in a Alfa Romeo and even a Maserati... only to be available in a handful of Jeeps sold in the USA...

FCA/Stellantis patent for this 6-cylinder in-line engine

This GME T6, presented in Q1 2022 by FCA, nicknamed Hurricane, is none other than the GME T4 to which 2 cylinders have been addedand various improvements (new EGR system, etc.).

As a reminder, the GME T4 is the 4-cylinder engine found in 200, 280 and 330 hp versions at Alfa Romeo in the Giulia and Stelvio, and at Maserati in the Ghibli and Grecale. Jeep USA also offers a 380hp PHEV version.


For those who have a 4-cylinder in their car, you'll recognize the same engine cover...


This GME T6 is perfectly suited to the Giorgio platform and could, why not, complement the 2.9L and 3.0L V6 engines of the Alfa Romeo Quadrioglio and Maserati MC20, Grecale Trofeo or new Granturismo.


It could even replace the V6, as this in-line 6-cylinder is compatible with plug-in hybrid technology, which could have been of interest in Europe to lower CO2 emissions... But it will probably never see the light of day, unless it becomes necessary in the USA.

There are currently two versions of this in-line 6-cylinder engine:

  • GME T6 Standard Output 3.0L: 420 hp / 610 Nm
  • GME T6 High Output 3.0L: 510 hp / 780 Nm

They are only available in the USA in the new Jeep Wagoneer and Jeep Grand Wagoneer, (which by the way both use a Giorgio LWB platform that should also have been used for the Alfa Romeo E-SUV), replacing the HEMI 6.4L V8 and Pentastar 3.6L V6 engines.

Stellantis communication about the new GME T6 engine

This Stellantis engine is manufactured at the Saltillo plant in Mexico and can be used in all STLA Large and STLA Frame platform vehicles... in countries where internal combustion is not banned.


While he gets a lot of praise from the motoring press, there seems to be a lot more to it than that. the new in-line 6-cylinder engine has one flaw: its noise, or rather its lack of noise..

  1. Another jewel right under our noses.
    It makes people want to move to countries where electric cars are not taxed, pretending it's a miracle solution when in fact it's a recipe for disaster.
    Ah if we're saved because the pure crap is still on the shelves.... What a revolution!!!
    The former sublime PSA is sharing its fabulous engines with us, even though it hasn't even been able to make a decent V6 (2 disasters that have never produced more than 200hp with 3.0l displacement) and I'm not talking about the crystal V10s in motorsport that were the laughing stock of F1 at the time.

  2. Absolutely, he'd be able to use the stla large ex giorgio platform and put the puretoc in it 😡
    If you come across the Peugeot family based in Switzerland, don't hesitate to tell them what we think 😉
    Let's hope fca will do as it did with gm, a nice divorce 😁

    • Ah, so they can put their infamous engine on such a platform.
      I'm also hoping for a divorce.
      To my knowledge, there's only one in Switzerland, in the canton of Vaud, not far from Geneva and Nyon (ARZIER-LE MUIDS (VD)).

  3. it's all because of these damned ecologists who are ruining our passion for cars by imposing their soulless electric merguez on us.

    • Except they'll be biting their fingers off.
      When you see that Audi is forced to buy Chinese platforms to make electric cars... it smells of scorching for everyone and Mercedes is already abandoning its electric suv that nobody wants.
      Toyota was right to take its time.

  4. Take a good look at that engine photo....Anyone want to fix anything in/on that Mess....The broken plastic parts and pieces going over everything will drive you crazy and so will the Time to do anything....The radiant Heat from Twin Turbos will cook all that plastic in a very short time...
