B) I would think so...but then again, production gasoline engines are less than that with BSFC of 0.4-0.6 lbs/hp/hr..close to what, 20-25%...? I would think there's a lot more to alternative power...TESLA, (motors, not Nikolas) is quite promising, don't you think...?
C) Perhaps upscaling was the wrong word...with around 50% thermal efficiency, 2 strokes need to make a desperate comeback...more so with mass production diesels.
D) Ah. Sorry. Forgot about that...automatics have always been a pain in the neck to decipher. As if conventional gearboxes weren't complex enough..however, slushboxes are quite inefficient despite the advantage with torque converters...maybe there should be a stickshift with a torque converter..nono, not the computer controlled man-o-matics with paddle shifts, but an H-gater with pure manual control...
E) The type C torsens with planetary gears (being currently used by Audi/VW, I think, for the non-haldex units) need them for uneven bias...1.5 or 1.75:1 or whatever...depending on design..but then again, I'm still a bit unsure as to the significance of the gear design.
b) Efficiency >80% (at full load)
c) Makes sense in a hybrid. Not really viable in small sizes.
d) Inefficiency actually comes from the torque converter. And the necessity of generating hydraulic pressure.
e) the "torque sensing" part does not use planetaries.
