Volvo are apparently going to announce the Polestar 2 later this year (to be released next year?), which I'm hoping will be something like the old S30 design wise. They will then announce a full EV version of the XC-40 sometime after that (to be releasing in ~ 2020) and is rumored that it is going to be around $45-50k.
If you want a PHEV from them, then Volvo are more about performance than pure efficiency. They have 'T8' variants of most of their cars (except the XC-40 sadly), which is a setup where the front wheels are driven by a supercharged, turbocharged 2L 4c engine with a small electric motor - and the rear is driven by a modest (~100hp?) electric motor. The combination means they usually get over 400hp/450nm and quite good mileage given their size/power. They aren't all that cheap though, around $55k for the S60/XC60.
Yeah the full EV for $40-50K is what I was interested in the most but what I really want is an EV V60. I was kicking the tires on the T8 version of the S60 but it was just a tad too expensive. Maybe I could stretch that far for a V60 variant (because that's what I really wanted) but I wouldn't spend that much money for something I wouldn't be totally satisfied with. I might have to come with a compromise with the wife. We get an S60 PHEV, she drives it during the week to work and back, I drive it all the other times. We get rebates + fuel cost reduction and that means we can afford a more expensive car.
I was also kicking the tires on a 330e but BMW for some reason aren't offering it with xDrive and I want xDrive for snowy MA winters. If they did end up releasing a 330ex I'd probably trade in the wife's 328xi immediately for it.
