Greetings! I'm most interested in reducing fuel consumption with a rarely-driven car that serves very useful purposes now and then for its load and people-carrying capacity: Volvo 245, 1979. I'm a chemist/biochemist from a research background originally, and I have a book in production with Oxford University Press all about energy and material economies of carbon compounds. From 3 years' worth of literature reading and calculations/modeling, I'm now sure that, at average yearly mileages, it's environmentally friendlier to keep a worthy existing car, work hard on reducing its consumption, and use it ever more sparingly, than to try to do something "environmentally-friendly" by buying a brand new car (of **any** type, ICEV, PHEV or BEV).
I look forward to some interesting advice and exchanges. I've just made a post on A-pillar fairings to reduce gutter turbulence. I'm also planning fuel injection retro-fit, and an extra gear for my transmission. Hypermiling via intelligent driving style also interests me a lot! Best wishes, Andrew
