Team Impul Hoshino had finished third in the Super Formula title standings last year. Karthikeyan will have Brazilian João Paulo de Oliveira as his teammate.
"I am really excited to confirm that I am driving in the Super Formula series this season with Team Impul. With a new chassis and turbocharged powertrains this year, along with a really strong grid of drivers, means it is going to be a fast and intensely competitive campaign," said Karthikeyan.
Super Formula Japan, erstwhile known as Formula Nippon has been running since 1973, with its driver roster including Michael Schumacher, Eddie Irvine, Pedro De La Rosa and Ralf Schumacher.
The series has switched to a new Dallara SF14 chassis this year, which is based on the Italian manufacturer’s GP2 chassis. The erstwhile V8s will be replaced by two-litre, 550 bhp turbocharged engines from the stables of Honda and Toyota – drawing parallels with Formula 1 which has switched from naturally-aspirated V8s to 1.6-litre turbos this year.
The official tyre supplier is Bridgestone, and the lap time of the new car is just 3-4 seconds slower compared to 2013-spec F1 cars.
"With the new 2014 F1 cars being over five seconds slower compared to last year, I think Super Formula may end up being the fastest series in the world," explained Karthikeyan.
"Of course F1 teams will improve massively during the course of the season, but it is amazing that a spec-series can be so close to the pinnacle," he further elaborated.
