Gas Engines Refuse To Go Quietly
The gas engine future now hinges on two overlapping strategies: radical combustion engine technology that cuts emissions without upending driver habits, and emotional performance variants that keep enthusiasts engaged even as electric vehicles gain ground. Together, Mazda’s 6-stroke engine patent and Maserati’s potential V-8 return show how carmakers are trying to keep internal combustion relevant for buyers who dislike charging queues but love sound, feel, and tradition. This isn’t nostalgia; it is a calculated bet that technology and emotion can protect combustion’s remaining market share against policies and marketing built around electric cars.
Mazda’s 6-Stroke Engine: Engineering Against EV Pain Points
Mazda’s 6-stroke engine concept is a direct answer to the everyday frustrations that still surround EVs: long charging times, range anxiety, towing compromises, and patchy charging infrastructure. Instead of abandoning gasoline, Mazda has filed a patent for a system that reforms fuel inside the engine, extracts hydrogen from ordinary gasoline, burns that hydrogen for propulsion, and captures the carbon before it reaches the tailpipe. In principle, drivers could fill up at any regular gas station and leave with near-zero CO2 emissions. The patent describes a six-stroke cycle that adds dedicated phases for recompressing exhaust, injecting fuel into hot gases, and separating hydrogen from carbon using heat and a catalyst built into the engine systems. It is designed to recover carbon, improve thermal efficiency, and deliver a carbon-neutral drive while keeping the familiar rhythm of combustion motoring.
Practical Implications: Carbon Capture Meets Convenience
If Mazda’s 6-stroke engine works outside the patent office, its appeal isn’t only technical; it is practical. The engine can switch between hydrogen-rich combustion and conventional gasoline when not enough hydrogen is available, meaning the car keeps running even when the reforming system cannot fully supply hydrogen. During those phases, emissions would still include CO2, but the goal is that most driving happens in carbon-capturing mode. Mazda’s filing even suggests that instead of visiting a dealer to empty onboard carbon tanks, drivers could rely on carbon-emptying stations integrated into existing fuel stops, reducing maintenance hassles. The broader promise is clear: gas-fueled engines could live on for decades, provided they become a meaningfully better choice than electricity in convenience, versatility, and total environmental impact. One quotable idea from the patent coverage sums it up: “With the right answers to those questions, this new Mazda six-stroke engine could give the internal combustion engine a compelling future alongside — or even in competition with — EVs.”
Maserati’s V-8 Return: Selling Emotion, Not Numbers
While Mazda fights EVs with chemistry, Maserati’s counter-offer is emotional. The brand’s head of engineering, Davide Danesin, has confirmed that a V-8 return is technically feasible for the GranTurismo, GranCabrio and possibly the Grecale, and that his personal opinion is that it is coming. Current platforms were designed to accept different powerplants, and feasibility studies are in place. Crucially, Danesin says the case for a V-8 is not about missing performance: “You don’t feel the need of a V-8 because of missing performance. I think the need of a V-8 is [about] having the proper engine for a certain vehicle. It is more a perception issue.” He also believes that if Maserati built one, it would sell, though not in big numbers. That line reveals the strategy: a halo engine for a subset of buyers whose loyalty depends on sound, character, and lineage rather than raw acceleration stats.
What These Bets Say About The Future Of Combustion
Mazda’s and Maserati’s moves share a common belief: there is still enough demand for traditional engines to justify new R&D. Mazda is pushing combustion engine technology toward near-zero CO2 by turning gasoline into hydrogen on the fly and storing carbon, while Maserati is exploring a purpose-built European V-8 likely derived from the Nettuno V-6’s 90-degree architecture, though it would require an almost complete redesign of components. Neither project chases mass-market volume. Mazda targets drivers who want EV-like emissions without EV compromises, and Maserati aims at enthusiasts for whom engine layout is part of identity. Gas-fueled engines could live on for decades if they become clever enough to satisfy regulators and emotive enough to satisfy buyers. The conclusion is blunt: EVs will dominate, but combustion will not vanish—it will retreat into niches where technology and passion combine to make gas feel like a deliberate choice, not a leftover habit.
