Reportedly armed with a hefty sponsorship portfolio, the HRT test driver – who has enjoyed a long-standing relationship with the team’s boss Colin Kolles – was promoted to race duties for the British Grand Prix at the end expense of Bruno Senna.
Senna returned to the cockpit at the following round in Germany, and reportedly given assurances that his seat was safe for the rest of the year. Yamamoto, in turn, continued at Germany but in place of Karun Chandhok, in a role he has continued to fulfil for the following two rounds at Hungary and Belgium.
Chandhok had recently expressed confidence that he would return to the HRT cockpit before the season was out, but it seems that Yamamoto might be set to spoil that party.
“I will finish the season,” he told the Dutch language formule1.nl in an interview.
“Whether I replace Bruno or Karun, I don’t know. But it is certain that I will do all of the races,” he added.
