De Tomaso Automobili has unveiled the final specifications for its new, naturally aspirated 7.0-liter V-12 engine. This powerplant, developed in collaboration with ItalTecnica, will power the upcoming P900 hypercar. The engine produces 900 horsepower and revs to a staggering 10,200 rpm, marking a deliberate departure from the industry’s trend toward turbocharging and hybrid systems.
A No-Compromise Approach to Engine Design
In an era dominated by forced induction and electric assistance, De Tomaso’s V-12 stands out as a throwback to classic high-performance engineering. The engine’s development began in 2022, with ItalTecnica’s expertise ensuring a blend of old-school philosophy and modern materials. It features 65-degree cylinder banks, dual overhead camshafts per bank, and four titanium valves per cylinder.
The crankcase is milled from solid billet aluminum, paired with a billet carbon intake system. Forged connecting rods and ultralightweight pistons contribute to the engine’s responsiveness, while a full gear-driven valve train – inspired by Formula 1 – eliminates the need for belts or chains. An eight-stage dry-sump system guarantees reliable lubrication under extreme track conditions.
Lightweight Construction and Performance
De Tomaso claims the entire engine unit weighs less than 400 pounds. This low weight, combined with the naturally aspirated layout, promises an exceptionally visceral driving experience. The P900 hypercar is currently designed exclusively for track use, but De Tomaso has suggested that a road-legal version may follow.
“The P900 will introduce new visual and aerodynamic changes”
The engine’s specifications, along with the distinctive 12-into-1 exhaust manifold, showcase De Tomaso’s commitment to raw performance. The P900 is expected to debut later this year, offering a glimpse of this engine in action.
De Tomaso’s V-12 represents a rare breed of high-performance engineering, prioritizing simplicity, responsiveness, and sheer power over hybrid complexity. This engine isn’t just a technical achievement; it’s a statement about the enduring appeal of naturally aspirated performance in a world that increasingly favors electrification.
