Don't use the environment to justify full EV. From that perspective, Tesla, ID.4, Mach-E, these are all a waste of precious battery resources. For the environment, all that matters is increasing total aggregate EV miles driven. One Tesla battery can be used in four PHEVs. 95% of single trips are under 30 miles. A 50 mile PHEV could easily cover this on pure electric even with cold weather. Instead of wasting a 80kwh battery in a Tesla, that could go into building four PHEV, basically increasing total EV miles driven four times faster.
So don't talk about the environment and say full EV is better than PHEV. Make other arguments if you want, but don't use climate change for your position, the math is clear, one Tesla = four PHEVs and 95% of trips are under 30 miles.
You have to account for a round trip where you can’t charge at destination, that charging above 80% is substantially slower, and driving under ~15% damages the battery faster (or so they say in some manuals).
That gives you 20%-80% of your quick and safe usage of your battery.
Also rated at 50 miles is more like 30 highway in real life. Adding all these things up makes 80mi as low as you want to go for normal US cities. In Europe it wouldn’t be an issue perhaps.
A broken-in real-world Leaf won’t finish a 60mi highway round trip without making you sweat towards the end. And that’s for perfectly planned trips, but a crash that makes you take a detour could put you in a risky situation. I’ve had to tow my GF more than once because something unexpected happened and she just simply ran out of juice. Not because of poor planning, but because life just happened that way.
One counter-argument to that is that many (I won't say most since I don't have sources) PHEVs don't get plugged in too often and are only bought for the tax advantages. An issue in some countries which give tax advantages to PHEV buyers, especially for company cars, where the driver doesn't have to pay for petrol.
So don't talk about the environment and say full EV is better than PHEV. Make other arguments if you want, but don't use climate change for your position, the math is clear, one Tesla = four PHEVs and 95% of trips are under 30 miles.
