Because I was unable to examine the effect of overexpressing FLRG in the complete absence of myostatin, it was difficult to ascertain the relative importance of these
additional ligands
compared to myostatin in regulating muscle
mass.
The hybrid system's
additional grunt (total system power is 335 hp
compared to the 335i's 300; it twists out 332 lb - ft of torque instead of 300) isn't readily apparent, as it's saddled with an extra 270 lb of
mass.
