Ex-F1 driver Massa will 'definitely find FE a challenge'

Massa was announced as a Venturi driver on Tuesday and has signed a three-year contract to race in FE, which will be the first category he has entered full-time since leaving F1 at the end of 2017.

NIO driver Turvey, who tested McLaren's MCL33 at the post-Spanish Grand Prix test at Barcelona this week, outlined the difficulties Massa will face in adapting his F1 experience to FE.

Why Formula E is so hard

"It's a very different formula - stepping back into a Formula 1 car is quite different from what I'm used to in Formula E," he said.

"As a driver, you get better if you drive different cars, but he'll definitely find it a challenge in Formula E.

"[With] someone of his experience it'll be interesting to see how he gets on.

"Next season there's a new car [Formula E will introduce its Gen2 car for the 2018/19 campaign] so it's a reset for everyone.

"It's great to have someone of his calibre and experience. I look forward to racing against him."

Turvey - a McLaren test and development drivers alongside his NIO commitments - qualified seventh and finished ninth on his FE debut at the London finale of the 2014/15 season, and matched that finish in that weekend's second race from 12th on the grid.

But he warned Massa that with the high-level of drivers racing in FE - 10 of the current grid have won races in the category - he is entering a very competitive series.

"I never expected it to be straightforward," Turvey said.

"I was able to get on top of it quite quickly, and now after almost [four] seasons, there's drivers with more experience so it's really competitive now and he'll see it's a really tough field."
