Anyway, we have to analyze why Subaru have preferred, apparently illogically, 6 speeds for efficiency and 8 for efficiency. Why don't you eight for each? The solution lines inside the coronary heart in the CVT system. When in effectiveness method, the CVT within the WRX doesn’t exactly match a rise in revs to an increase in speed.
DAF's Variomatic established the template for CVT packing containers, and all versions on supply now operate along similar traces.
A belt-driven design and style gives about 88% effectiveness,[4] which, although reduced than that of the guide transmission, can be offset by enabling the engine to run at its most successful RPM whatever the vehicle's speed.
