Striking Performance Without Multiple Gears: How Does Your Electric Vehicle Do i

Internal combustions engines can safely and reliably spin only up to a certain rate, around 7,000 RPM in the average fuel-powered car. Within the confines of this limit, they produce usable torque and power in an even narrower rev range. As such, a multi-ratio gearbox is needed to provide a wider range of torque and power to suit different driving conditions.u00a0u000b

  2. Torque Generation: Internal Combustion Engine vs Electric Motor Internal combustions engines can safely and reliably spin only up to a certain rate, around 7,000 RPM in the average fuel-powered car. Within the confines of this limit, they produce usable torque and power in an even narrower rev range. As such, a multi-ratio gearbox is needed to provide a wider range of torque and power to suit different driving conditions. 

  3. Can EVs Even Have Gears? Depending on the vehicle, multiple gears could give an EV better acceleration at lower revs or higher efficiency when cruising (which would lead to a better range). However, the pros of a multi-ratio gearbox need to be weighed against the cons, quite literally. The additional weight could eliminate any gains in efficiency. 

  4. Do You Need Gears in an EV? In a nutshell, not really. Gearboxes are heavy, complex pieces of machinery that leak quite a bit of the power generated by the engine (or taken from the battery) in the form of friction losses. By eliminating gearboxes, EVs like the MG ZS are lighter, simpler, and more efficient. And as for speed and acceleration? You get plenty of that on account of the electric motors’ torque being available on demand.
