Specifications and Features

This section is dedicated to providing information on the specifications and features of each of the
Vortex GTT models.

EPAS Option Announced For all Vortex GT models
Now an option for all Vortex models; Electric Power Assisted Steering (EPAS).
This is the very best that technology can offer. It is also offered as a retro-fit for existing cars.
The assisting motor and ECU are combined into the column itself, in one compact unit, supported
by a unique crossbeam.

  • Engine power is only tapped when needed (unlike any hydraulic system that saps power
    constantly, is heavier and thus adversely affects fuel consumption).
  • Assistance is speed variable, alllowing effortless low speed effort with higher speed feel.
  • The column specified is adjustable for reach and height.

The dynamic effect of this is to make the Vortex feel much more agile, not least because the steering
ratio can be quickened without unacceptable steering weight.

This is done either with a quicker rack ratio or shorter steering arms. Also the castor angle is
increased to retain ideal self-centering, by shimming the wishbones. POA.
