AAACV8 ~ I'm still not fussed on the Hybrid concept. It still requires maintenance and visits to a Servo. Two power packs instead of one = Double the worry? I'm happy to be proved wrong though. Being flexible with power sources makes the subject quite interesting to observers like myself. I noted the mention of the Mirai in the link you provided. The 'jury' is still out for me re Hydrogen . Who knows, it might be an ideal alternative for some folk. Quote: "Launched in 2014, the first-generation Toyota Mirai proved the global potential of using hydrogen to power clean and sustainable mobility with emissions of nothing but water" If Jeremy Clarkson ever road tests a Tesla Roadster, he will probably buy one !
