Reigning GP2 Series champion Fabio Leimer has hinted that he may be involved in the inaugural FIA Formula E Championship having participated in pre-season testing at Donington Park.

The Swiss driver has been called up by the Amlin Aguri outfit to trial its second car alongside Katherine Legge, Leimer replacing Antonio Felix da Costa who has missed much of testing thus far due to commitments as the STR F1 reserve driver and in DTM.

As such, Leimer has completed more miles than the Portuguese driver, raising the possibility that he could at least land in one of the four seats still available - two at China Racing and one each at Dragon Racing and Andretti Autosport.

Indeed, Leimer, who is this year competing in the World Endurance Championship with Rebellion Racing, says he hopes to be able to share more soon.

"We are still in contact with the team, but I can't say anything about it," he told "My manager is doing the work, but I am testing here so maybe I will try to be in a car this year."

Having come from GP2 and sportscar racing, Leimer admits it has been a challenge to adapt to the rigours of the new all-electric Spark machine.

"It is completely different for me, but it is for everyone. It is quite a heavy formula car and also the engine, but at the end it doesn't matter if you come from GP2 or Formula 3.

"Driving-wise, it is quite easy but there are lots of things around it. You can go with full power or low power, so there are many things you can change as a driver."
