The Judge:
Taffin accepts, “We had several issues across the cars in Melbourne but we have recreated the problems in the dyno at Viry. Most are fixed and the remaining will be under control by Friday in Sepang. While we anticipate further issues may occur we are much more able to react quickly to minimize their impact.
Sepang is one of the circuits whose technical requirements will change under the new regulations. In the V8 era the circuit sat towards the middle of the table for the challenge it posed for engines but now it will be one of the toughest races of the year.”
Yet the mantra from Horner of 2013 still repeats in our consciousness, “whenever you run an F1 car, you are learning something”. It may appear obtuse to observe, though conversely, when you can’t run an F1 car, you are falling behind the learning others are achieving.
In terms of track time and subsequent ‘real running’ data gathered, the Renault engine is light years behind that of the Mercedes.
The demands of Sepang will not offer Red Bull, Caterham, Lotus or Toro Rosso much comfort as Taffin explains. “Of the six main components of the Power Unit, the internal combustion engine will be under the most pressure in Malaysia. The humidity in Sepang made it a little bit easier on normally aspirated engines since power comes down as the water content in the air increases.
This means we were generally able to offset the impact of the two long straights. This year we won’t have this luxury. With a turbo engine the air intake is controlled at all times regardless of ambient conditions so those long straights will really start to hurt. As a result Sepang will become a lot less forgiving as twice a lap the PUs will be flat out, with the turbo revving at close to 100,000rpm for over 10 seconds.”
