Chassis
The first chassis from March, AGS and Ralt were developments of their existing 1984 Formula Two designs, although Lola's entry was based on and looked very much like an IndyCar. A few smaller teams tried obsolete three-litre Formula One cars (from Tyrrell, Williams, Minardi and RAM), with little success—the Grand Prix and Indycar-derived entries were too unwieldy—their fuel tanks were about twice the size of those needed for F3000 races, and the weight distribution was not ideal. The first few years of the championship saw March establishing a superiority over Ralt and Lola—there was little to choose between the chassis, but more Marches were sold and ended up in better hands. The form book was rewritten in 1988 with the entry of the ambitious Reynard marque with a brand new chassis; Reynard had won their first race in every formula they'd entered. This would continue in F3000. The next couple of years saw Lola improve slightly—their car was arguably marginally superior to the Reynard in 1990—and March slip, but both were crushed by the Reynard teams and by the mid-90s, F3000 was a virtual Reynard monopoly, although Lola did eventually return with a promising car and the Japanese Footwork and Dome chassis were seen in Europe. Dallara briefly tried the series before moving up to Formula One, and AGS moved up from Formula Two but never recaptured their occasional success. At least one unraced F3000 chassis existed—the Wagner fitted with a straight-six short-stroke BMW. This was converted into a sports car, however.
