I think there is some sort of rule that 1kg of rotational mass is really equal to more than that in reality, ie. the wheel may weigh 10 kg but the extra work the engine needs to do means its more like it weighs double. I can't give you the exact science of it and I couldn't be bothered researching it so you'll need to do that yourself if you want to.

And a 100kg passenger would increase fuel consumption, every article you read on how to improve economy says reduce the weight of your vehicle by removing unnessesary items from the car.

That damn freeloading passenger is costing me MORE money.
Just don't tell her.
