London ePrix: Prost dominates, Di Grassi extends points lead

From pole position, Prost was never challenged up front, pulling away from fellow front row starter Bruno Senna and surviving a safety car restart with 10 laps remaining to take his second career Formula E win and his first of the season.

But behind Senna, who finished five seconds down in second to get his first career podium, all eyes were on title protagonists di Grassi and Buemi, who spent much of the 33-lap race running nose-to-tail. 

The pair had started from 10th and 12th respectively, although di Grassi had made his way up to sixth place by the 12th lap and had help from teammate Daniel Abt keeping Buemi behind.

Abt was given a warning for blocking a clearly frustrated Buemi, but the Swiss driver had found a way past to move into seventh regardless by the time the mid-race car swaps arrived.

In his second car, di Grassi made short work of Robin Frijns - who had slipped from fourth to fifth behind Jean-Eric Vergne with a slow stop - to take fifth, with Buemi following through for sixth.

But, trying a move around the outside at Turn 2 of the Dutchman on lap 20, Abt make contact with Frijns approaching Turn 3, spearing into the wall and then back into the path of Frijns. Both were eliminated on the spot, and the safety car was called.

The action resumed with 10 laps remaining, but there was drama when di Grassi damaged his front wing while he was attacking Vergne for fourth place.

This incident did little to slow down di Grassi however, as he set fastest lap soon after - although this honour (and the critical two points that come with it) eventually fell to Nelson Piquet Jr.

Buemi could do nothing to find a way past di Grassi, and with two laps to go found himself passed for sixth by Sam Bird, just as Oliver Turvey crashed out of third at Turn 14.

That brought out the double-waved yellows, helping Vergne hang on to third place ahead of di Grassi.

Bird had been set for fifth place, but slowed on the run to the finish line - catching out Buemi, who collided with the rear of the ailing DS Virgin car and damaged his car's nose.

He still crossed the line fifth, one place behind di Grassi, ahead of Antonio Felix da Costa and Bird, with Nick Heidfeld, Jerome d'Ambrosio and Mike Conway completing the top 10 finishers.

Di Grassi now takes a three point lead over Buemi into the title decider on Sunday, while Prost's win means he moves ahead of Bird into third place in the standings.
