I know that the gas powered engine in the Karma only powers a generator which in turn recharges the batteries. However, from an environmental perspective, how is that different than having a gas powered engine directly powering the drivetrain? Are emissions somehow different when the gas engine is powering a generator rather than a drivetrain? Thanks.

I think, in theory, it's supposed to be more efficient as it hits an ideal rpm and stays there.
