Now if you want to use "peak bsfc" as your argument, we are assuming peak bsfc in both "pusher" and "generator" here.

But if the tdi direct drive has to "compete" with the generator, the "at the wheels" bsfc for the tdi is like 206 gm/kwh. Whereas the same efficient engine running a generator is like 301 gm/kwh.
Find me a 220cc motor with the same BSFC range as the TDI you quote
