Pros and Cons

  • Positives
  • Negatives
BYD eMAX 7
  • Spacious, easy to drive, powerful and sophisticated driving experience, feature rich cabin
Tata Sierra EV
  • Brings back iconic nameplate in a greener avatar, will be a compact SUV and hence more affordable, the design stays true to the original
BYD eMAX 7
  • Not as much road presence due to it's height, less space in the 3rd row than some of it's rivals, could have been more practical and cushy experience in the 2nd row
Tata Sierra EV
  • Just a design study as of now, no plans of production for the next two years, will be a smaller SUV than the original
