Formula One driver Narain Karthikeyan will join Pedro de la Rosa to complete the HRT line-up for the 2012 Formula One World Championship, the Spanish team announced on Friday.
"Narain... will contribute continuity and stability," team principal Luis Perez-Sala was quoted as saying in a statement.
"He is a quick, intuitive and secure driver who met his expectations despite a lack of continuity last year. Of the eight Grands Prix he contested in 2011, he only failed to finish on one occasion and had a great performance in the last race he took part in."
