In 2025, Lamborghini still manufactures V12 engines. The Italian manufacturer continues to find ways to make them more powerful without resorting to forced induction. The “few-off” Fenomeno is proof of this, featuring the brand’s most powerful V12 to date: 823 horsepower, which is nine more than the Revuelto.
Intentional Room for Improvement
Rouven Mohr, Lamborghini’s technical director, emphasizes that this power is deliberately limited. He explains that the decision to add only nine horsepower was a “portfolio choice” and not a technical limitation. The naturally aspirated 6.5-liter engine would have even more to offer.
Meticulous Optimization
Where do these nine additional horsepower come from? Mohr specifies that it comes from rigorous parts selection, minimized tolerances, and reduced friction. It’s a fine-tuning, not a major design change like altering the compression ratio.
Synergy with Hybridization
The Fenomeno is also a hybrid. Its tri-motor electric powertrain is more powerful, increasing from 187 horsepower (Revuelto) to 241 horsepower. The total power of this sharply angled car thus reaches 1,065 horsepower.
A Revolutionary Battery
Mohr details that the battery, although the same size, uses a different cylindrical cell technology than the standard (pouch), offering more energy and power. This change required a redesign of the cooling system.
Untapped Electric Potential
Each electric motor could theoretically develop 147 horsepower without modification. Switching to an 800-volt system would increase power but would require a different inverter and a heavier battery, which is not relevant for Lamborghini at this stage.
The Future of the Naturally Aspirated V12
Mohr’s statements open the door to speculation. Could the 6.5-liter V12 reach 900 horsepower without turbos? Could the combined power approach 1,300 horsepower? Whatever the case, Lamborghini continues to push the development of its iconic combustion engine, defying all predictions of its demise.
