A1 Team Switzerland dominated the third and final official practice session at Sepang International circuit this morning, setting the scene for an incredibly close and exciting qualifying session this afternoon.

Neel Jani, who masterfully converted his pole position to a win in last year's Sepang Sprint race, set the pace early on and went on to record a blisteringly quick lap of 1m49.176s on used tyres, 40 minutes into the hour long session.

The Swiss racer was closely followed by France's Loic Duval, who clocked the second fastest time ahead of India's Narain Karthikeyan, with just over half a second separating the top three.

Despite spinning off the track into the gravel at the start of the session, GBR's Oliver Jarvis finished fourth fastest while USA's Jonathan Summerton and A1GP debutante Germany's Michael Ammermüller impressed the crowd by setting the fifth and sixth fastest times respectively.

South Africa's Adrian Zaugg was classified seventh while Brazil's Sergio Jimenez, who has been on strong form all weekend despite this being his first experience of the Sepang circuit, set the eighth quickest lap time of the morning.

Local hero Alex Yoong was obviously a lot happier with the set up of the Malaysian car, pleasing the home crowd by ending the session 10th fastest.

Current championship leader New Zealand's Jonny Reid was confined to the garage for much of the session due to a problem with second gear, but the team remain confident that the issue will be resolved in time for qualifying, which starts at 14.15 this afternoon.
