Re: Guzzling?
There is no "4.3 litre" Honda Civic, the largest standard petrol engine fitted to a Civic is 2.0 litres (though there was a 2.2 litre 4 cylinder diesel available for a while from 2011). That is available in multiple markets, and is reasonably fuel efficient. This doesn't preclude a custom engine transplant, but the only "4.3" litre engines I can find are V8's from either Ford or GM, that seems unlikely. Custom Honda V6 installs have been done for racing/drag etc.
Of course, if one calculated the ecological footprint of a vehicle over its lifetime, electric cars don't stack up well at all. But it's not actually about "saving the world", it's all about virtue signalling and seeming to do something. Heaven forbid that we actually use logic and reason when deciding on these things...
