F307
The Dallara F307 Formula 3 features 2.0-liter four-cylinder producing approximately 210-230 horsepower depending on engine supplier (Mercedes-HWA, Volkswagen, Opel, Renault, Toyota, or independent tuners) through six-speed sequential transmission and rear-wheel-drive at approximately 550kg minimum weight meeting FIA Formula 3 regulations. Chassis specification includes carbon fiber composite monocoque, pushrod suspension with double wishbones front and rear providing extensive adjustment capability, aerodynamic package with front wing and rear wing elements, ventilated disc brakes, racing slick tires, and open-wheel single-seat cockpit with FIA-compliant safety cell and head protection.
F307 represents 2007-specification Dallara Formula 3 chassis evolution from F305 through upgradable aerodynamic kit, dominating international Formula 3 championships including FIA F3 European Championship, British F3, and various national series through combination of proven chassis dynamics and manufacturer-neutral philosophy allowing customer teams engine choice flexibility. The Dallara domination of Formula 3 category establishes single-supplier control similar to spec racing series though engine competition maintains technical diversity, creating standardized junior single-seater ladder supporting driver development toward Formula 1 and professional motorsport careers, with F307 generation preceding F308 evolution introducing enhanced safety and aerodynamic refinement continuing Dallara championship-winning lineage from 1981 Formula 3 entry establishing Italian constructor dominance in junior open-wheel categories.
