The 280bhp turbo-charged inline-4 engine that was used in the Dallara GP3/10 between 2010 and 2012 was upgraded to a 400bhp 3.4 litre (207 cu in) naturally-aspirated V6 unit, with initial estimations suggesting that the chassis would be up to three seconds per lap faster than its predecessor, which proved to be accurate during pre-season testing at the Autódromo do Estoril.
