Shouldn't be as bad as last year, but I don't expect it to be good enough for them to win. Mercedes should be very strong. Highly likely Max will be up there too and then Ferrari is a bit of a question mark. Going by last year's performance, a podium would be good damage limitation.
As for last year, straight line speed wasn't a problem actually, because I have seen it mentioned a couple of times. They just had no traction out of the slower corners. After T5, it was half a second down already, so clearly something was very wrong. The car didn't work at all in the first part of the lap.
