The 39 year old driver ended the afternoon of testing with the fastest time of 1:12.519, set during a full power 250Kw lap near the end of the session.

French driver Jean-Eric Vergne ended the afternoon session in second place after his own full power effort on his penultimate lap, keeping Lotterer honest with a laptime just 0.088 of a second slower.

Both Techeetah drivers managed to get into the top 3, with reigning champion Antonio Felix Da Costa ending the day in third place, just over a tenth of a second behind Lotterer.

New driver Nick Cassidy closed the first day of pre-season testing with fourth position for Envision Virgin Racing, followed by Alexander Sims in fifth for Mahindra.

Rene Rast continued to impress with sixth for Audi, with debutant Norman Nato in seventh for Venturi, leaving Dragon’s Nico Muller to finish behind him in eighth.

Rookie Jake Dennis was ninth for BMW Andretti, matching where he finished in the morning session. Robin Frijns rounded out the top 10 fastest times for Virgin Racing, with Audi’s Lucas Di Grassi being close behind the Dutchman.

Sebastien Buemi was 12th for Nissan, with Maximilian Gunther in 13th, ahead of Oliver Rowland. The three drivers were covered by less than a tenth of a second.

Stoffel Vandoorne in 15th was the leading Mercedes, with Sam Bird in 16th for Jaguar and Porsche’s Pascal Wehrlein down in 17th.

Alex Lynn ended the day 18th for Mahindra, just ahead of Sergio Sette Camara in 19th for Dragon. The Brazilian Driver set a lap time faster than Nyck De Vries, the second Mercedes driver.

Oliver Turvey was 21st fastest for the NIO 333 team, having completed 51 laps of the Ricardo Tormo circuit; the most of any driver in the session. Mitch Evans was 22nd after spending most of the session stuck in the garage, ahead of Venturi’s Edoardo Mortara in 23rd and the other NIO 333 of Tom Blomqvist rounding out the field in 24th, almost two seconds behind his teammate.

With the top 20 being covered by just one second, the field seems extremely competitive going into day two of testing.
