Audi has fitted 3 asynchronous motors on their SQ8 and I’m wondering why? I mean, Tesla on their dual-motor, has a synchronous motor for urban use and an asynchronous one for like highwhay and stuff like that. Makes sense I guess. So why would Audi chose 3 asynchronous motor? Efficiency speaking, from what I recall, asynchronous motors are « worst » than synchronous one in a « torque needing » situtation. Is it a way for Audi to say that the SQ8 is to be used on the Autobahn only sort of thing? Thanks for your insights.
The conspiracy theorist in me wonders how car manufacturers are going to design in obsolescence. Maybe by adding more motors that could fail…
If we get to the point where these things last a lifetime, what will they sell ?
i think audi’s decision to use 3 asynchronous motors on the SQ8 is interesting. i wonder if it’s a way for them to emphasize high-speed performance. it’s definitely a unique approach compared to tesla’s dual-motor setup. excited to see how it performs!
Was this done to keep close to their Quattro history? To provide better ‘AWD’ in a sporting manner, while taming torque steering in the front end?
You know the high-end Tesla has 3 motors as well, right?
Two induction and one permanent magnet.
When cruising on the highway, the two large induction motors shut down for efficiency. But when you stomp on the pedal, you get all 1100 horses.

I don’t know about Tesla specifics, but most EVs using both synchronous motor and asynchronous(induction) motor don’t work that way. It’s usually PM synchronous motor(PMSM) for the real axle used in most scenarios(urban and highway), and induction motor on the front axle, which is used only when you need extra power or 4WD. The reason is that PMSM is more efficient, so it is used most of the time.
if i’m dropping that much cash on a ride, i’d expect top-notch performance too. german carmakers gotta step up their game.
