Good steering assistance, perfect handling and the utmost energy efficiency: drivers expect all these things not only from mid-range cars but also from compact models. Volkswagen had to measure up to these expectations when defining the specifications for the up! steering system and chose electric power-assisted steering (EPAS) produced by NSK Steering Systems.
NSK developed an extremely compact EPAS system for the VW up!, installing the electric power-assisted steering unit to the steering column in order to save space (steering column EPAS). EPAS technology uses approximately 0.2 l less fuel per 100 km than an electro-hydraulic power steering system (EHPS) because it only consumes energy when the steering assistance is actually needed.
The power steering system in the VW up! is also used to automatically centre the steering wheel and car wheels
