Not exact matches
And although a turbo engine can't have the super-high compression ratio of Mazda's naturally aspirated Skyactiv engines, it boasts 1.6 times less
mechanical loss as a result of less internal
friction.
Higher
mechanical losses (
friction) due to the number of gears to drive (differentials, axles, driveshafts,...)
Friction - reducing design features, including all - new ultra-low viscosity transmission fluid, internal thermal bypass, minimal number of non-applied clutches and other lower
mechanical spin
losses, contribute to the 10 - speed's effect on improved vehicle efficiency.
In EV Drive operation, when the battery - powered drive motor is used for either acceleration or regenerative braking, a clutch disengages the stopped gasoline engine from the drivetrain to eliminate efficiency
loss from
mechanical friction in the engine.
OK, so again: ASIDE from all
losses and
mechanical frictions etc., etc., expended in displacing horizontally without gaining or losing potential gravitational energy, there is a NEW CONDITION with the moved mass.
