Alex Fontana will partner Jarno Trulli at the London ePrix in Battersea Park this weekend, Motorsport.com can exclusively reveal.
The 22-year old Swiss currently races in GP3 for Status Grand Prix and has done a one-off deal to race in the No.18 Trulli Spark-Renault.
Official confirmation from the team is expected later today.
Fontana will replace Vitantonio Liuzzi, who is unavailable for the London ePrix due to Asian GT commitments at Okayama in Japan.
