Oliver Turvey worried by Hong Kong slump

NextEV are keen to get to the bottom of an efficiency problem which saw them fad from the front row of the grid to the fringes of the points places during the Formula E season opener in Hong Kong last weekend.

After leading from pole early on, Nelson Piquet slipped back after making contact with the wall while trying to avoid Jose Maria Lopez's stricked DS Virgin car.

Meanwhile, Oliver Turvey's pit stop was slow. Both drivers then continued to slip back in the second half of the race.

"It seems in the race a lot different to qualifying," said Turvey. "I did everything I could and it was a struggle – the first stint and the second, trying to hit the energy targets [while] the other cars were much quicker."

"Qualifying was great, but that's a flat-out single lap," he said. "It's a very different format to the race.

"We have to look into it. You have to have an efficient package."
