It doesn't have any connection with the engine or the smooth surface, because mp4-29 doesn't have the problems of last year's car. It's the package and the set-up work of the new package.
You can't say that for sure. The truth is that only a few details transpired regarding the engine power modes teams ran in Australia, so a part of the gain will probably come from the engine as well. Also, it's pretty hard to measure the absolute gain of an upgrade package as we don't have enough data (fuel loads, setup, aero configuration, etc) to compare the old and the new. If what they're saying it's true, then probably Mclaren will battle Williams for a podium on Sunday. If it's dry.
