Independent e-Drive Suspension

BRIST offers 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)
