A frame for a vehicle includes a first housing and a second housing. The first housing and the second housing each define an interior space. The first housing and the second housing each comprises a first side portion and an opposing second side portion. The first housing and the second housing each include a first pair of triangular members coupled to the first side portion and a second pair of triangular members coupled to the second side portion. The first and second pairs of triangular members each support a wheel. A support assembly couples the first housing and the second housing. The support assembly includes an external lattice structure and an internal lattice structure. The external lattice structure is coupled to the first housing and the second housing. The internal lattice structure is coupled to the external lattice structure, the first housing, and the second housing.

A center upper frame connection for a space frame can comprise a pair of outer support beams spaced from each in a width direction, a rearward center support between the outer support beams, and support beam arch. Each outer support beam can have a rearward frame connection boss and a forward center frame nodal connection boss. The rearward center support can have a pair of rearward frame connection bosses oriented at an angle relative to each other, and a pair of side frame connection bosses provided on opposing sides of the rearward center support. The support beam arch can be provided adjacent to the outer support beams and the rearward center support. The rearward center support can be located on a longitudinal centerline of the support beam arch and can be parallel to the outer support beams.
