The fastest lap from last year's Valencia Formula E test, a 1m25.763s set by Mortara, was overturned for the first time by the Swiss driver's new team-mate Maximilian Guenther on the second day of running in this year's test.
Guenther's best lap of the day, a 1m25.449s, only showed an improvement of just over three-tenths over a less powerful and heavier car - despite expectations that the Gen3 machinery would offer a significant increase in performance.
