Andretti driver Scott Speed is making his Formula E debut on home soil and says that the pre-season testing at Donington Park will help him a lot in getting used to his car.
"Certainly it's going to be a big learning curve for us especially with the conservation method and requirements for the battery unit," said Speed.
"Having driven the car already it's a good foundation, so I still hold pretty good expectations for a decent result," he added.
Speed can't wait to drive his Spark-Renault SRT_01E in race conditions.
"I'm looking forward to getting back in an open-wheel car again. It will be a very cool homecoming if you like," he said.
"The racing is much like riding a bike so I felt good when I tested the car but it's different to anything else I've done before."
Trulli driver Vitantonio Liuzzi is a late replacement for Michela Cerruti and will be racing alongside Jarno Trulli.
Liuzzi did not expect to be ‘suddenly' partaking in the race on Saturday.
"I was on holiday in Miami and I was supposed to fly away yesterday night but I had a nice lunch with Jarno when he arrived on Tuesday and we talked and he said Michela may not be coming so keep yourself on standby.
"Yesterday morning I had the great news that I could race with this team. I'm happy to race for Jarno as he is a person I really respect and as a driver. I'm looking forward to race here in Miami and I will do my best to push the team forward."
Loic Duval is also another new starter and will join Jerome D'Ambrosio at Dragon Racing.
