Yeongam has taken us away from the relentless slow-speed, long-duration corners of Singapore and into a more conventionally configured circuit - and suddenly the Red Bull's advantage does not look as outrageous.
Lewis Hamilton set the fastest headline/low-fuel time, a tenth of a second quicker than Sebastian Vettel's Red Bull, with Nico Rosberg (Mercedes) and Mark Webber (Red Bull) closely matched just behind. On one-lap pace there is then a significant gap back to Ferrari and Lotus.
Looking to the numbers of the longer runs there was no apparent Red Bull advantage at all. In fact, quickest on the softer, super-soft tyre was Kimi Raikkonen's Lotus ahead of Rosberg and the second Lotus of Romain Grosjean. On the medium prime tyre, Hamilton put together the fastest average, though it was of relatively short duration.
