Narain Karthikeyan will drive for HRT in Friday practice at the Japanese Grand Prix, as he continues his preparations for an F1 race return in India.
Regular driver Vitantonio Liuzzi will give up his car for Karthikeyan, who will be taking Daniel Ricciardo's place in the HRT lineup for his home race in Delhi next month.
Liuzzi will be wearing a special helmet in Japan to pay respects for the victims of the earthquake that struck the country earlier this year.
"For this grand prix I've wanted to pay my respects to the victims of the earthquake that struck Japan earlier this year by wearing a special edition helmet named 'Embracing Japan,' designed by Kaos Design," explained the Italian. "The helmet will later be put up for auction with the benefits going toward charity."
