Mexico City Formula E: Renault's Buemi fastest in free practice

The Renault e.dams driver topped both sessions at the Autodromo Hermanos Rodriguez, where the all-electric series is racing on an altered version of the Formula 1 circuit.

Buemi left it until the final five minutes of the faster second session to post a new benchmark, ending FP2 fastest with a 1m03.341s.

That put him a quarter of a second clear of Daniel Abt, who set his lap before suffering a gearbox issue.

Abt's team-mate Lucas di Grassi was a further 0.15s back as Abt Audi Sport looks to consolidate its position as the Renault squad's nearest challenger.

Nicolas Prost was almost half a second slower than team-mate Buemi in FP2, and not much faster than Venturi's Mike Conway and the impressive Oliver Turvey for NEXTEV TCR.

The tricky 18-corner circuit brought mistakes from several drivers, with Buenos Aires ePrix victor Sam Bird's spin at the Turn 1 chicane and a similar mistake error by Bruno Senna at Turn 13 the most notable.

Home favourite Salvador Duran stopped on track thanks to a suspected software glitch and brought out a red flag.

Buemi had earlier been the only driver to dip below the 1m04s mark in FP1, which was considerably colder than the second session.

His 1m03.995s knocked Turvey from a rare stint atop the times in the NEXTEV TCR 001, with the Briton ending up third quickest after a late improvement from Loic Duval.

The opening session passed largely without incident, save for a few lock-ups and a red flag for the stopped Simona de Silvestro.
