Unsurprising, for a Ferrari. I suspect it's designed for performance and not efficiency. Atrocious mileage is par for the course in this segment (see the Veyron)
I've done Stockholm - Oslo on a single charge in early winter, which is almost exactly that distance, so I'd say it does! Even kept me nice and toasty along the way!
The actual number of the EPA range is imaginary, yes. But it's useful for comparisons.
But if we're talking about comparisons between two vehicles, the vehicle with a 122kWh battery and a 280 EPA range will go less far and is much less efficient than the vehicle with a 84kWh batter and a 300 EPA range.
They’ve historically had eye watering regular maintenance bills, even outside of them generally having a reputation for being temperamental. Maybe Ferrari will continue pioneering in their own way and make an unreliable and expensive to own EV
