"Back in F1 in 2011. Signed a deal to race for HRT", Karthikeyan tweeted.
Karthikeyan also thanked the Tata Group in his twitter page. Tata was his main sponsor in 2005 when he raced for the Jordan Formula 1 team. Karthikeyan however failed to secure a race seat from 2006 onwards. Karthikeyan secured a fourth driver role for Williams F1 in 2006. He moved to the A1 GP India team in 2007 and with the closure of the A1 series, Karthikeyan moved to NASCAR in 2010.
The race drive with HRT will see the 33 year old back racing in Formula 1 after a gap of 6 years
