In order for the 8 MJ option to be viable, Toyota will apparently need to invest quite a bit in making the car lighter to accommodate for the additional weight of the 8 MJ hybrid architecture. Besides, it is unclear if Toyota can stick with the current supercapacitor units. According to reports, they may need to look for alternate energy storage solutions, which may be risky reliability-wise.

There has to be ways of saving weight in the car and probably on the hybrid side. The switch to a battery unit would only be beneficial if it was a gain over the capacitor. Nothing so far says the capacitor cant do 8mj, only that itd compromise weight. Well thats probably the balance of the car being affected rather than overall weight.
If they do go 8mj, thats a 33% increase in electric power. The total petrol fuel flow decreases 89.5-88.5kg/h or a 1.1% decrease. Petrol energy drops from 62.6-62.0mj/l or a .95% decrease. But total energy goes from 68.6mj/l-70mj/l or an increase of 2%. Definitely worth it if you get a total increase of 2% total power per lap. If 6mj=480hp, is it 8mj=640hp?
Btw,
heres a great read on what TMG is and what it features. An amazing place, very detailed.
