Full HRT race seat decision due at Silverstone

It is not yet clear if Bruno Senna has permanently lost his HRT race drive.

The struggling Spanish team’s boss Colin Kolles told reporters at Silverstone late on Thursday that reserve Sakon Yamamoto will be regular driver Karun Chandhok’s replacement teammate this weekend.

He said no more information will be available until a press release is issued on Friday morning.

But Kolles did tell the BBC that Yamamoto, who turns 28 on Friday, is not guaranteed the seat for the rest of 2010.

“A decision as to who will drive for Hispania for the rest of the season will be taken over the weekend,” he said.

With the situation almost certainly related to the drivers’ available sponsorship funds, Finland’s Turun Sanomat said Japanese Yamamoto is better financed than HRT’s other reserve driver Christian Klien.

Senna, the 26-year-old nephew of the great Ayrton Senna, made his debut with HRT this year with the backing of Brazilian companies Banco Cruzeiro do Sul and Embratel.
