Production Rimac Concept_One unveiled with 1072 hp [video] Rimac has announced plans to unveil the production version of the Concept_One at the Geneva Motor Show. Looking virtually identical to the concept that debuted at the 2011 Frankfurt Motor Show, the production model has a slender grille, a bulging hood, and a rakish windscreen. The car also features a carbon fiber rear diffuser, distinctive taillights, and 20-inch lightweight alloy wheels with Pirelli P Zero tires. By Michael Gauthier Green - Feb 22 2016
