Ex-F1 racer Jarno Trulli says Formula E powertrain looking strong

The 2004 Monaco Grand Prix winner has endured a difficult season, but having partnered with Italian technology company Tecnomatica to form Motormatica, one of eight manufacturers approved to produce motors, inverters and gearboxes for the 2015/16 season, he is more optimistic.

"We are now running the engine on the dyno," Trulli told AUTOSPORT.

"The gearbox has now been machined, so we should be on schedule and it's looking pretty good.

"It will be different compared to this year because for the first season we didn't have any information about the engine and gearbox.

"We are running what we are given and that has caused a lot of reliability and performance issues.

"We should be more in control of next year's project and have a better understanding of the car and problems."

Trulli's squad has had a troubled season, with his best finish a fourth place in the Punta del Este round in Uruguay in December, and he sits 20th in the championship.

Although the Italian took pole position for the last round of the championship at Berlin Tempelhof, his race was ruined by what he described as "sky-high" energy consumption.

The Italian blames his team's struggles in season one on its late start thanks to it being the last to get a slot on the grid after taking over the Drayson entry.

"We expected to be better, to be honest," said Trulli.

"We missed a big part of the preparation of the season because we were the last team to enter the championship and there were a lot of details that we didn't have time to catch up on and to investigate more.

"We entered when everyone else was rolling and this also caused a big problem because it made the personnel a last-minute call.

"We were not able to sign everyone to a full contract, which we will do for next year.

"We are looking to sign engineers and mechanics for next year on a full-time basis."
