LEAFIELD, England (AP) — Japanese driver Kamui Kobayashi says he is racing for Caterham for free in Formula One this year after being named in the English team's 2014 lineup.

The 27-year-old Kobayashi, who returns to F1 after being dropped by Sauber at the end of 2012, has also paid Caterham 1 million pounds ($1.65 million) in sponsorship raised by his fans to get him back in the sport.

Kobayashi says "I don't need or care about money. I just want to drive ... so I am racing for free."

Kobayashi drove for Ferrari in the GT Pro class of the World Endurance Championship last season, and was offered a new contract by the team this season.

Alongside Kobayashi at Caterham is Swedish newcomer Marcus Ericsson.
