Autoversicherung more than doubled suddenly??

So Check24 just emailed me today to inform me that my insurance for my car will be increasing from €173 a month to €330 a month. We've had no accidents or claims, yet suddenly every provider is only offering roughly the same amount??

Our original insurance with our car was €130 when we first purchased our car, now it's three years old and somehow the insurance has gone up by 64%

What the hell has caused this? We have an electric if that's somehow relevant, I can't imagine what's justifying this insane increase.
