Combo to go

The Weekend Post - Motoring - - Front Page -

THE Geneva mo­tor show would not be com­plete with­out a wacky con­cept from Rin­speed. This year it’s the Dock+go, a Smart-based combo that can tow its own recharg­ing sta­tion. It takes the box trailer to a whole new level.

Any elec­tri­fied city speed­ster could serve as the ba­sis for “Dock+go”. For demon­stra­tion pur­poses Rin­speed se­lected an elec­tric, two-seat Smart car as the ba­sis. Dif­fer­ent “packs” can con­vert the tiny elec­tric car to dif­fer­ent pur­poses. In Geneva it was a rolling “sound pack” filled with gear from au­dio spe­cial­ist Har­man (above).

An “en­ergy pack”, fit­ted with a range ex­ten­der or ad­di­tional bat­ter­ies, pow­ered by a fuel cell or equipped with a com­bus­tion en­gine, pro­vides the cru­cial ex­tra kilo­me­tres to reach more dis­tant desti­na­tions.

The docked third axle drives the ro­tat­ing sec­ond axle and, in do­ing so, also recharges the on-board bat­ter­ies of the city speed­ster.

It’s been dubbed the world’s first Var­i­o­hy­brid. And to top it all off: when the pack with aux­il­iary bat­ter­ies is docked and the ve­hi­cle is not in use, the pack will even pro­vide electricity to the owner’s home or serve as a buf­fer for the public en­ergy grid, in ef­fect turn­ing it into a “smart grid”.
