    The key thing for a smooth ride is minimizing unsprung mass (I.e. the mass not supported by the suspension). This mass needs to be able to bounce up and down quickly as you go over bumps. More mass means stronger suspension.

    Wheel hub motors have been around for a while but they have always had ride problems.

      You’re right but another key thing for a smooth ride is large sidewalls and how many cars have thinner ones for aesthetics?

      Many people also drive vehicles with solid axles that are very bumpy.

      Cars don’t have to be optimal in every category, maybe this one will find a niche.

          Bigger wheels for bigger brakes, which EVs need because of their massive weight.

            US EVs have massive weight, but the European ones do not, and Regen means smaller rotors.

            Only the US market is obsessed with stupid ranges that no one does daily. US EVs are just carrying around 1000lbs of excess battery, which takes energy.

              BYD Tang (EU market) 380kW, 108kWh, 2600kg

              Funnily enough, i didn’t cherry-pick the biggest one i could find—i cherry-picked the one i saw that said “EU market”. lol
