Kind of. This team is specifically using hub motors, thus bypassing the need for traditional axles. Hub motors are notoriously inefficient, though, so you don’t see them in normal BEVs which typically mount the motors near the center of the axle (as part of an “e-axle”). Basically, this team’s car is purpose built only for acceleration and thus gets away with doing things you wouldn’t see in cars that need to maintain speed or drive efficiently. Great ingenuity by them!
- tromp 3y agoThey needn't be inefficient, as demonstrated by their use in the hyper efficient Lightyear0 solar powered car. But they do have plenty downsides [1]. [1] https://evcentral.com.au/why-dont-evs-have-four-in-wheel-motors/ https://evcentral.com.au/why-dont-evs-have-four-in-wheel-mot...
- toss1 3y agoYES The use of hub motors is probably best when acceleration is paramount, but when handling starts to come into play (e.g., on road courses), it is likely best to bring the motors inboard and spend the extra weight and complexity of axles, as the unsprung weight outboard of the suspension is a serious detriment to handling.
