Felix Rosenqvist said he was happy to come away with a win from Hong Kong after his earlier mistake looked like it has cost him a chance of victory.
Abt lost his and the works Audi team's first win in the electric single-seater series when a post-race inspection revealed the barcodes on the inverters and motors did not correspond with those declared on one of Abt's car's technical passport.
Former world champion Nico Rosberg is open to the prospect of getting involved with Formula E in a non-driving role. We didn't really have an idea of what our M4 vehicle is like on a street circuit until now, but this weekend really showed that we have the pace to be very competitive.
In the dramatic race two today, Rosenqvist started from the pole position, dropped to eleventh but fought his way up to finish second.
The Mahindra driver had spun out of the lead from pole at the first corner but recovered to second place after Mortara then spun his Venturi vehicle with less than three laps left. "So this has been a really rollercoaster weekend", the 26-year-old said.
"It's not the way you want to win, I don't feel like a victor".
The New Zealand driver benefited after the victor of race two, German Daniel Abt, was disqualified following a post-race inspection of his Audi vehicle. "What we are apparently suspected of is a administrative mistake in the car's passport that didn't give us any advantage at all".
Daniel Abt's joy following his maiden Formula E win didn't last long.
A problem in the auto swaps cost Abt a podium on Saturday, though he still charged back to fifth, and on Sunday he took victory after poleman Felix Rosenqvist spun at the first corner at the start and long-time race leader Edoardo Mortara spun with less than three laps remaining.
Rosenqvist claimed pole, fastest lap, and victory in the second race of the season, a feat never achieved before in Formula E's short history.
