George Russell, who set the pace in first practice, reckoned the asphalt left Miami as a “true outlier” and unlike anything else on the calendar.
He said: “We’ll go into Sunday a bit of an unknown with the track being resurfaced.
“It's still not performing like any other circuit. So, it's a true outlier here, which is cool in some regards.
Amid complaints over too few overtakes in the opening rounds of the campaign that have left viewers to comment on dull races, drivers have predicted that trend to continue in Miami.
At a track where there were 45 passes last season, drivers have pointed to the lack of grip off the racing line and the Pirelli tyres dropping marbles.
Russell continued: “It can be really difficult to race because you can't drive off-line.
“You’ve seen with a few people, myself included, you put one wheel off and there's no grip whatsoever.”
