Super Formula: Karthikeyan's season ends after typhoon cancels races at Suzuka
The Indian couldn't score points in his fifth Super Formula season.
Narain Karthikeyan started his final round in the 2017 Super Formula season at Suzuka, finishing 15th in the Saturday morning practice.
The two-part qualifying for the two races on Sunday, started under treacherous conditions with rain continuing to fall at the Japan's Formula 1 circuit.
Karthikeyan qualified 11th for Race 1, while he was eighth for the second race on Sunday, as poles were shared between Team Tom's Andre Lotterer and Team Impul's Jann Mardenborough.
Docomo Dandelion's Tomoki Nojiri was second in both the sessions, while Team Tom's Kazuki Nakajima was third for Race 1 and Docomo Dandelion's Takuya Izawa took third in Race 2.
However, after qualifying the organisers announced cancellation of the Sunday races due to a severe typhoon declaration by the weather department.
As a result, Inging's Hiroaki Ishiura was crowned the Super Formula champion for the second time in his career - after winning it the first time in 2015.
The Japanese driver was able to beat Team Mugen's Pierre Gasly by 0.5 points, as the Red Bull junior and Toro Rosso driver missed the chance to fight for the title.
The Frenchman, however, took the rookie honours, ahead of third placed Team LeMans' and Formula E's Mahindra Racing's Felix Rosenqvist
Meanwhile, Karthikeyan racing for TCS Nakajima Racing outfit failed to score any points for the first time in his Super Formula career, with teammate Daisuke Nakajima managing to score the two points.
