It sounds bizarre but I want to try it.
That all makes sense except why do some EVs have real gears? I feel like Porsche probably knows what they’re doing when they put one in theirs.
Theirs unfortunately has no efficiency benefit. There’s two motors in the taycan, front and back.
Front motor is single speed, and once the car hits 62mph it shifts to second in the rear motor only.
The taycan is all about being fast, not efficient.
Maybe that’s the use for a transmission then? Like CPU cores, efficiency cores and performance cores? Dunno, not an expert here. I do think what we think now is unlikely to be what we think as the technology matures and gets reinvented.
Yes, in reviews and media documents it is mentioned the Taycan has the second gear to be able to maintain Autobahn level speeds. It’s not explicitly mentioned, but Porsche won’t outright confirm efficiency last I looked, so even they don’t think it helps range. Just speed.
But it’s not that there isn’t efficiency to be gained, it’s just so small it’s not worth it. In order for even a 2 speed ev, the shift point would need to be approximately 70-80mph to realize efficiency gains.
That’s just not something that’s done with EV’s. Most are city centric, and even if you are driving 70-80mph in an EV, you’re hitting peak efficiency of the motor anyways. It’s a bell curve, so it’ll only start to taper off not drop like a cliff. Although, the one side might drop faster due to how resistance works.
