Rally America

Subaru was an integral part of Rally America from its inception. The Subaru WRX STi version of the Impreza vehicle, had already become the most numerous competitive rally car in North America. Subaru became a sponsor of the series and many prizes and other incentives were provided by the company both for rally in general, and Subaru driving teams in particular. A fully stocked parts truck was dispatched to all national events, offering Subaru teams unique access to parts and expertise on scene. There were discounts on parts for teams using Subaru Rally Team USA parts.[4]

Mitsubishi was Subaru's primary competitor in North America, with its Mitsubishi Lancer Evolution series of cars. In the hands of competitive drivers, the Evo proved a challenge to the larger quantity of WRXs, often edging into top three finishes.

Ford Motor Company has had a long history in rallying item rallycross both World Rally Championship and in North America. Ford made a unique appearance in American rallying at the 2009 X Games. Driven by Tanner Foust, Ken Block and Brian Deegan, three open-class Ford Fiestas were dominant (two of the three claimed podium positions) throughout the weekend. Block, the eventual winner, praised the car, while Foust has said he would like to see a factory-backed Ford Racing team competing regularly in Rally America.[5] For 2010, Ford announced that they would be sponsoring a Fiesta in Rally America and the X-Games.[6]

While not often contending for top overall spots they were good cars for those contesting the two-wheel-drive championships and for beginners. The Volkswagen Jetta, Volkswagen Golf and Volkswagen Beetle all had many appearances and much success in Rally America events.

The Scion Rally xD debuted in the two-wheel-drive category at the 2010 Oregon Trail Rally with Christopher Duplessis at the wheel. In 2011, Duplessis switched to a Ford, and the Scion xD was piloted by Andrew Comrie-Picard.[7]

The engine is turbo charged and must be based on a production engine with the power being limited by the use of an inlet restrictor. The body must be recognizable as the original car. There is a minimum weight also enforced dependent on the engine.

2.5L or less naturally aspirated 4wd production vehicles with no minimum weight. Like the open class the body must be recognizable as the original car.

The chassis generation must match the appearance and modifications of the car. Thus, one can take a chassis from a 2006 Subaru WRX and put a 2003 WRX shell around it, but all parts must be allowable for a 2003 WRX. Engine displacement cannot be more than 2.6 liter with multipliers, and a limiter is placed on any forced induction system. A minimum weight is also enforced. Many other parts can be replaced, as long as they are an option from the manufacturer.

These are based on the old FIA Group 5 and Group 2 standards. Both are limited on weight, displacement, and must be based on cars with a production of 1000 per year. Power may be sent to either the rear wheels or the front wheels.[8]
