Most BOSS GP entries are more recent secondary level single-seaters such as GP2 cars and Renault World Series cars along with a small number of 90s and 00s Formula 1 cars, but common EuroBOSS entries included Formula One machines from Benetton, Jordan, Tyrrell, Minardi and on occasions a V12 Ferrari. Other frequent entrants in BOSS series have been Lola and Reynard CART chassis, the 1997-2002 Panoz (aka G-Force) and Dallara IndyCar chassis. From 2012, the 2003-2011 Dallara and Panoz Champ Car chassis have also been used after the switch to the new IndyCar formula.
