My understanding is that a factor in making EVs seem like they have lower top speeds is because of increased safety standards/laws in some countries. Those countries require speed limiters for speeds too far above highway speeds. Many ICE engine designs were grandfathered in without needing to be updated with such speed limiters, but EVs are new designs and don't meet any such "grandfathering" criteria.
- dharmab 4y agoYour understanding is incorrect. Speed limiter laws have only been introduced or planned for commercial vehicles in major markets. AFAIK there is no jurisdiction planning speed limiters for personal vehicles (although there are informal agreements such as the 155mph limiter on German sports cars and the 186mph Japanese sportbike top speed). Also, there are laws in some countries regulating that vehicle top speed cannot exceed the speed rating of the stock tires, so some vehicles that would be otherwise capable of higher speeds sometimes have limiters so a less expensive tire can be shipped as standard equipment.
