Lets say the car runs full electric under 50kph. The batteries last for say 100km. If you drive less then 100km both ways to work, you are getting *mpg because you are never going to use fuel. If you drive 120kph, to work and back, you are driving 20km on petrol.

That's not how most hybrid cars work..
I'm not sure what tech this car is supposed to use, but most hybrid cars have an electric motor that provides all of the power to the wheels. Then there is a completely separate gasoline engine powering a generator. The engine provides
just enough power for the car at cruising speeds. During times of acceleration, the batteries provide the extra power necessary. When the car is decelerating or standing still, the batteries
recharge.
I'm willing to bet on top of an extremely efficient electric motor, the actual gasoline V8 uses some sort of active cylinder control, (variable displacement technology). So just cruising around town in light throttle situations it would only would use 4 of the 8 cylinders and the smallest electric motor. Then when you go WOT you use the full potential of the motor as well as the other 2 larger more powerful electric motors.
As for the 78mpg claim, well yes that is probably what the maximum you can get if the car is driven a particular way. However, if you've followed Porsche history you would know they're not known for making ridiculous claims; in the past they have called out other manufactures on their claims. In my opinion if driven a certain way this hybrid will get close to what they're claiming as far as fuel economy.

That technology has been around for awhile, they are actually airless tires which are much more efficient than regular tube tires.
Here are pictures of the actual concept.
