The naturally aspirated engine was developed specifically for track use.
The Italian automaker De Tomaso was founded in 1959 by Argentine-born entrepreneur Alejandro de Tomaso. In 2014, the brand rights were acquired by Hong Kong–based investment firm Ideal Team Ventures, led by CEO Norman Choi, who spearheaded the marque’s revival.
In 2019, the company unveiled the prototype of the De Tomaso P72, though the production version didn’t arrive until last year. In the meantime, De Tomaso introduced another model: the track-only De Tomaso P900, first revealed in 2022. The company has now shared detailed information about its V12 engine.
Originally, the P900 was expected to use a V12 developed by Capricorn, weighing approximately 485 pounds and capable of revving to 12,300 rpm. However, De Tomaso has since announced a partnership with the engineering firm ItalTecnica. The company has previously developed engines for projects such as the Totem GTAmodificata, Totem GT Super, Totem GT Super Jarama, the Automobili Mignatta Rina, and the Garagisti & Co GP1.
The newly developed 7.0-liter naturally aspirated V12 was engineered specifically for track performance. It features a 65-degree cylinder bank angle and a multi-stage dry-sump lubrication system with an aluminum oil reservoir.
The engine is equipped with forged connecting rods and ultra-lightweight pistons. Each cylinder bank has dual overhead camshafts, with four titanium valves per cylinder. A lightweight carbon-fiber intake manifold is also used, and total engine weight does not exceed 440 pounds.
Output is rated at 900 horsepower at 9,500 rpm, with a redline set at an impressive 10,200 rpm. A sequential transmission from Xtrac sends all power to the rear wheels. Unlike many modern automakers, De Tomaso has deliberately rejected electrification for this project. The focus, the company says, is on throttle response and engine sound—not just headline numbers.
The P900 is a track-only supercar (not street legal), built on the same chassis and carbon-fiber monocoque as the P72. Its aerodynamic package is more aggressive and visually dramatic. Target dry weight is just 1,984 pounds.
Other performance figures have yet to be disclosed, as the car itself is still under development. Initial plans called for the first customer cars to be completed in 2024, but that timeline was not met.
The official debut of the De Tomaso P900 is now scheduled for this year, though a specific date has not been announced. Buyers will be offered an extensive customization program, and production will be limited to just 18 units.
