Felipe Massa believes Abu Dhabi Grand Prix officials should look into the possibility of widening the entry to the hairpin before the long back straight in a bid to help passing.
Although the use of two DRS zones at the Yas Marina circuit helped deliver more passing moves than there have been in the past, the general consensus was that the track still remains a bit too hard to overtake on. Massa thinks that re-profiling the hairpin would offer drivers the possibility of taking different racing lines through the corner, which could help make passing easier.
"It was interesting," said Massa when asked about his views on how well DRS had worked. "I still believe that this is a difficult track for overtaking. In my opinion, they need to change a little bit corner seven, maybe even make it wider like in India.
"But anyway, it was OK – It was much better than last year for sure. Using DRS and everything, I was able to fight and overtake Mark [Webber], but for some other cars it was more difficult to overtake."
Red Bull Racing team principal Christian Horner questioned the value of the second DRS zone, especially as many drivers who had lost a position at the first zone on the main straight found themselves easily able to get back in front at the second activation area.
"I think it was a bit too soft, the second one," he explained. "Mark [Webber] made a move on Jenson [Button] and it was too easy for him to counter that. It is the sort of thing that can be tidied up for next year, but there was certainly more overtaking than there was 12 months ago."
