Formula Libre (also known as 'Formule Libre') is a form of automobile racing allowing a wide variety of types, ages and makes of purpose-built racing cars to compete "head to head". This can make for some interesting matchups, and provides the opportunity for some compelling driving performances against superior machinery. Auto racing (also known as automobile racing or autosport) is a sport involving racing automobiles. ...
Most recently, the British Open Single Seaters (BOSS) Formula has spawned EuroBOSS [[1]] and USBOSS [[2]] equivalents, signalling the re-emergence of Formula Libre events. Racing purists have come to embrace Formula Libre as an alternative to the increasing preponderance of spec racing series, and a number of competitors' vehicles are cars orphaned by discontinued spec series. The EuroBOSS Series is Europes fastest motor racing series and 2006 saw races at quality circuits across Europe, including Mondello Park, Brands Hatch, Zandvoort and Race Resort Ascari. ...
Formula Libre has provided some ambitious young drivers with an alternative to series with higher competitive costs and lower performance. Most recently, the UK's BRDC awarded their Rising Star award to 2004 EuroBOSS Champion Scott Mansell [[3]]. The British Racing Drivers Club (or BRDC) was founded in April 1928. ...
The concept is arguably the oldest in motor racing:
Grand Prix racing adopted Formule Libre briefly, beginning in 1928.
Formula Libre racing is currently very popular in South Africa.[4]
Germany's Interserie runs as a Formula Libre, mixing single-seat formula cars with sports racing prototypes. [5]
1971's Questor Grand Prix was a well-attended inter-series race between Formula 1, Formula 5000, and ChampCar teams, featuring top drivers at California's Ontario Motor Speedway.
The Rothmans 50000 race in 1972 permitted almost any kind of single-seater or sports-racer in a 300 mile race at Brands Hatch, competing for a £50,000 prize fund (considerably more than most Grands Prix of the day). Most of the grid consisted of Formula 1 and Formula 5000 cars, with some Formula Two machinery and the odd more exotic vehicle.
Formula Libre races usually closed the programme at British club meetings in the 1970s, allowing not only cars that didn't suit any of the classes racing that day to run but also giving drivers of formula cars another chance to race.
