Let's be honest gas is still king where I'm from (planet earth) or we all would jump ship from the carcinogenic dirty earth destroying machines to the super clean lithium machine ???.
Come on a Nissan leaf/Tesla etc is a stinking machine to, the mining of lithium plus the carcinogenic fumes or nuclear waste that power plants produce to power these machines as renewables alone can not charge all the cars.
In theory the energy is passed from traditional petrol tanks and exhaust pipes to the power plants where poor people live so the fumes and waste are moved from the citys where most energy is used for mobility by the better off to the poor areas its stinking in my view, when governments promoted diesel less than ten years ago then they expect us the poor to dump all our cars and move to electric and we take the loss of the vw scandel its all bullshit nonsense, specially when the main energy consumers are the governments themselves living the high life jetting to meetings and cruising in fat cat jaguars aircon on max.
There's still plenty of innovation with combustion engines with freevalve camless tech the good old girl looks like she still has plenty of life left in her and the added bonus of being able to be used in a cleaner manner.
On topic I think a hybrid is a good thing but for a speed demon both setups need to be used together really not one system at a time, with both setups there will be a fair bit of extra weight for the electric motor to carry it would need to be drove hard on both setups with ideal gearing so they back each other up for big power like the hypercars rather than a Prius range extender.
