Independent e-Drive Suspension

  • BRIST provides MARKET DISRUPTION OPPORTUNITY with its special independent drive axle solutions!
  • Unlike the global players offering e-axle options on heavy rigid beams, BRIST is building its e-drive portfolio on independent suspension.
  • Being light in system and unsprung weight, offering a wide free central space and reducing time to market via modularity are key advantages of BRIST.
  • Compared to its best competitor e-axle product, taking the advantage of independent suspension, BRIST offers minimum 10% lighter system weight.
  • Same BRIST independent suspension can be used as:
    • Drive or non-drive,
    • Steerable or non-steerable,
    • Central drive or corner drive.
  • The modular structure reduces time to market of a new electric vehicle family, while reducing the complexity between various version of a vehicle family.
  • BRIST independent e-drive suspension are not preferred by bus segment only, but also fitting very well to electric van and electric truck applications.
  • Moreover, BRIST partners many disruptive electric vehicle projects across the globe (e.g. Arrival, BYD, Bluebus, CRRC ZELC Europe, Bristol Superlight and many more)
