Alfa Romeo: an Italian V6 or an American in-line 6-cylinder to save the Quadrifoglio?

Since his return to favour with the Alfa Romeo Giulia Quadrifoglio and Alfa Romeo Stelvio Quadrifoglio, Alfa Romeo's mechanical signature is based on an engine that has become emblematic: the V6 2.9L biturbo. An engine of Italian origin, today closely linked to Maserati with the Nettuno V6 engine. But as standards evolve, electrification takes hold, and Stellantis reshuffles the cards in its industrial strategy, one question keeps coming up: which engine for future Quadrifoglios?

From an electric promise to a return to electrified combustion

Until a few years ago, the management of’Alfa Romeo announced a complete switchover to 100 % electrics for its high-performance models. A radical vision, now clearly nuanced. The economic context, customer expectations and market realities have prompted the brand to rethink its plans. Future generations of the Giulia and Stelvio, expected around 2028, are likely to offer electric versions... as well as thermal-hybrid versions. The Quadrifoglio badges could therefore survive thanks to electrified powertrains, like Maserati's future Trofeo versions. It remains to be seen which ones.

The natural scenario: the continuity of the Italian V6

If we follow a brand and image logic, the answer seems almost obvious. The merger between Alfa Romeo and Maserati changes the game. The two brands could potentially share common technical foundations. In this context, extending the life of the Italian V6 seems an obvious choice.

It's hard to imagine a Maserati Trofeo powered by an American engine such as the GME in-line 6-cylinder. And if Maserati retains an Italian V6, Alfa Romeo could logically follow suit for its Quadrifoglio models. Beyond technology, it's a question of identity. A high-performance Alfa Romeo equipped with an electrified Italian V6 would have far greater marketing power. The history, the sound, the character: everything points in favor of this solution.

The credible alternative: the American 6-cylinder in-line engine

But there is another option. More rational, more industrial: the 6-cylinder in-line GME, nicknamed Hurricane. Initially developed by FCA before the merger with PSA, this 3.0L engine is already a reality in the USA. In particular, it equips certain Jeep models with power ratings of up to 510 hp and 780 Nm in its most powerful version.

On paper, it ticks a lot of boxes. Hybridization-compatible, powerful, modern and, above all, already integrated into the Stellantis ecosystem, it could be adapted to future Alfa Romeo models. Especially as the brand already uses the 4-cylinder GME. Switching to an in-line 6-cylinder from the same family would make sense from a technical and industrial point of view.

But this scenario raises several limitations. The main one is geographical: this engine is currently produced in Mexico. To integrate it into European models, production would have to be launched on the Old Continent. A heavy investment, which would only make sense if shared with other Group brands (why not Lancia!).

A question of philosophy rather than technique

At the end of the day, the choice is not just a technical one. It's almost philosophical. Alfa Romeo must decide what it wants to be in the years ahead. A deeply Italian brand with a strong mechanical identity? Or a brand integrated into a global Stellantis logic, where rationalization takes precedence over emotion?

The American in-line 6-cylinder is a credible solution. High-performance, modern and already amortized, it could perfectly meet the requirements of future standards. But what a Quadrifoglio lacks is perhaps its soul. While the hypothesis of an American in-line 6-cylinder engine cannot be ruled out, it does not seem the most obvious. An Alfa Romeo Quadrifoglio is sold as much for its performance as for what it represents. And on this point, an electrified Italian V6, shared with Maserati, remains a far more coherent proposition.
