Kolles hints HRT to keep same race lineup

Team boss Colin Kolles has backed Sakon Yamamoto's claim that the Japanese driver is set to keep his race seat with HRT in 2010.

Yamamoto, and reportedly a healthy raft of personal sponsors, joined the struggling Spanish team's race lineup at Silverstone, and said this week he will stay in the car for the rest of the season.

The 28-year-old said he did not know if he would continue to have Bruno Senna as a teammate or whether Karun Chandhok will return, but boss Kolles has hinted that HRT will keep its current drivers for the last six races of 2010.

"I think there is no reason to make any changes so far," said Dr Kolles.

He said he is pushing hard to improve HRT's financial situation, having recently added some new sponsor logos to the Cosworth-powered F110.

"Obviously this is a positive sign but we have to work hard to get as much sponsorship as possible for 2011," said Kolles.

"As I mentioned before, in F1 you need a lot of support and this is what we are trying to achieve," he added.
