Dallara in chronologischer Reihenfolge

The Dallara F308 is an open-wheel formula racing car, designed, developed and built by Italian manufacturer Dallara, for Formula Three racing categories, in 2008. It was used in different Formula Three racing categories and competitions between 2008 and 2011. It was later replaced and succeeded by the F312, in 2012. The F308 can be upgraded to either the F309, the F310, or the F311, through Dallara's annual add-on kits. These include modifications in the area of ​​aerodynamics such as additional air deflectors or similar or improved suspension units.

Addax, or Barwa Addax was a Spanish motorsport team owned by the bank Addax Capital, which competed in the GP2, GP3 and GP2 Asia Series.

The first official test of the Dallara IR12 chassis was carried out by Dan Wheldon at Mid-Ohio on August 8, 2011. Phase I of testing involved Wheldon, and was planned to involve three road courses and three ovals, over a total of about twelve days. The second test was held August 18 at Barber, and the third was held on the USGP road course at Indianapolis on September 1. Oval tests took place in September at Iowa and Indianapolis. Honda (Scott Dixon) and Chevrolet (Will Power) began Phase II of on-track testing at Mid-Ohio in early October. A scheduled test at Las Vegas was cancelled after Wheldon lost his life in the 2011 race held at the track, resulting in Dallara renaming the chassis, a practice adopted from Ligier, which named its race cars "JS" for Jo Schlesser. Testing resumed in late October and continued through February at several venues including Sebring, Fontana, Homestead, Phoenix, and Sonoma. Lotus first took to the track on January 12 at Palm Beach, and testing by individual teams began on January 16. A full-field official open test took place on March 5–6 and 8–9, 2012 at Sebring International Raceway.
