HRT's Formula 1 cars will return to action after owner Teo Martin reached an agreement to run two of them in the BOSS GP series.
Martin, a Spanish businessman and scrapyard owner, bought the assets of the defunct HRT team after the Spanish squad folded at the end of last year.
Among that, Martin acquired two 2011 chassis with all the required equipment to operate them.
Martin has now reached a deal with businessman Carlos Molla to field the two cars in the championship. Work is already underway to get the cars ready before the end of May.
The BOSS GP series field comprises, among others, old Formula 1, CART and IndyCar cars.
