That is a fair question. First when it comes to full electric conversion the infrastructure is just no there yet to support the cars adequately, and when it comes to hybrids the battery technology has not reached a stage of maturity that is worthy of investment as a car "buyer". That is, early adopters of these new technologies, in my opinion, often get burned.Why? R Hybrids not the near-distance future of Automotive Companies before they go Electric?
Goodness, 500 pounds, is well, not insignificant.Currently the batteries are quite large and heavy. This seems to be evolving to smaller, lighter and more efficient batteries every year. It is interesting to see some of the predictions for the future . The battery in my Subaru hybdrid added 500 pounds to my car.
Funny, I just can't get on board with the battery bonanza.......I guess I am the proverbial slow adopter. I guess I would have held on to my horse and buggy at the turn of the century............I have figured out a sophisticated reason to stop giving a ride to someone I don't like..."the hybrid battery is too heavy"
“As for what comes after plug-in hybrids, Lamborghini has already given a taste with 2017's Terzo Millennio electric supercar concept, which Domenicali said could potentially be ready for production—technology-wise—by around 2026. But according to Domenicali, Lamborghini is also exploring the potential of hydrogen-powered supercars.”What bout Hydrogen Power instead of Oil?
This is from March 2019. In August 2019 Lamborghini announced they would be pushing back the Aventador successor to 2024, and Huracan successor to 2025 I think.
