Times will obviously improve by the time we get to qualifying practice and the race. The average lap times indeed suggest that Audi may potentially face a hard time.
Looking at the
Best Sector Times of FP2, it looks like the Audi are losing time in the first sector (approx. two tenths). The top speed measured on the straight is similar though. I would have expected the Toyotas and Audis to be closer in that first sector. There is maybe room for improvement on Audi's side in sector 1.
Funnily, the Audis are marginally faster in the last sector which is supposed to be more to the advantage of the Toyotas.
