[Ant man and the Wasp] How do the shrunken vehicles travel at the same rate as their regular size?

The engine rpm would have to increase  at an incredible rate. The wheels would have to turn exponentially faster. The transmission....... I am willing to accept "Pym particles" but if there is any plausible science I'd love to hear that first. Thanks!

The square root law states that shrunken materials increase in strength comparitively to the size reduced. Similarily, since the engines move by force applied to the surface of the tops of pistons (reduced by squares, not cubes) the proportions of energy to weight have increased several Pym factors. Finally, since the molecules of the shrunken Pym fuel have remained constant, the energy result is the same as a non-Pym vehicle. The net Pym result is a super strong, super energetic, Pym particle mobile that moves at Pym factors of Pym. 

TLDR: PYM PARTICLES!!!!!  'Nuff said.
