Electric Power Assisted Steering

Electric Power Assisted Steering (EPAS) replaces hydraulic steering system, offering:

  • Reduced fuel consumption and CO2 emissions 
  • Standard system soaks 3-4% of overall fuel consumption
  • EPAS system soaks approx 0.2%
  • EPAS system gains 0.2-0.4 litres/100km
  • Simplified  vehicle assembly / production costs
  • Reduced noise
  • Reduced weight

Our product supports an advanced steering system

NGF's glass fiber cord for engine timing belts is used in the Electric Power Assisted Steering (EPAS) system that can help to cut fuel consumption and reduce CO2 emissions.

The EPAS technology has been developed by NGF's customer Gates Power Transmission with ThyssenKrupp. The system delivers a fuel saving of around three to four per cent, with a consequent reduction in CO2 emissions, because it only requires power during actual manoeuvring, unlike standard hydraulic systems, which are a constant drain on the engine.

The EPAS drive belt uses 0.2mm Glass Cord produced at NGF. The diameter is key to this application because the belt has to go around a tight pulley system, which requires it to be extremely flexible. The Glass Cord, which actually spirals around the rubber belt, is also coated with our RFL latex composition for optimum adhesion.

EPAS is already used in around 2 millions vehicles in the European market and its adoption is expected to increase throughout Europe and North America. Demand for NGF Glass Cord will increase as vehicles with EPAS system become main stream all over the world.
