Get acquainted with Mercedes' F1 'Power Unit'
The power units have been the root of the off-season mess, and in case you're not clear on how they work - or don't work, as teams are finding - the Mercedes team has provided a video laying it out. The turbocharged 1.6-liter V6 has to work with two power units, one that collects brake energy and one that collects turbo energy for a battery called the "energy store," all of which is meant to help go a race distance using about 33 percent less fuel than last year. For the teams that actually make it race distance, at least.
