Baku, June 16, AZERTAC
Leading Formula 1 team figures expect a dilemma over set-up for this weekend's inaugural grand prix in Azerbaijan on the streets of capital city Baku, according to Eurosport.
At 3.732 miles, the 20-turn circuit is the second longest on the calendar and has been described by its designer Hermann Tilke as the fastest city track in the world.
But alongside its fast, sweeping corners and long straight, there is also a narrow and twisty section through the Old City.
"It's going to be quite a challenge for the engineering teams because you've got this requirement for huge straightline speed, it's a very low efficiency circuit," said Williams performance chief Rob Smedley.
"Then it almost goes into this Monaco-style street circuit in places. It looks like it goes into some reasonably sweeping, quite quick right handers or medium speed right handers.
"So there's going to be some real challenges there. The place where I would say it's most similar to is Spa.
"You'll see some teams taking different choices for both qualifying and the race."
Red Bull boss Christian Horner believes the length of the main straight, which measures 1.4 miles, will push teams towards a low downforce set-up.
"The straight is twice as long as the longest straight in Montreal, which is enormous," he said.
"It's going to be fascinating to see what set-ups people adopt. I guess the length of that straight will push most people towards the lower end of the downforce spectrum."
