Singapore preview quotes: Bridgestone

Hirohide Hamashima - Bridgestone Director of Motorsport Tyre Development: "The layout looks challenging and we have not seen any races on the circuit so teams will be relying solely on their simulations before cars take to the track.

"As with any street course, we expect finding grip to be the focus for many and the grip level to change over the weekend. The circuit layout looks interesting and this will be a very exciting, unique race track.

"We have looked at many different aspects regarding a race taking place at night and we have no specific concerns. Bridgestone have good experience in endurance motor races which run at night so this has been useful.

"The temperatures will be cooler than during the day and there will be no heat generated from the sun's radiation, but we predict an ambient and track temperature of around 27 degrees Celsius, which is warmer than some tracks we visit during the day. Ultimately, the way the tyre works at night will be the same as it works during the day."
