Emerald’s Chassis Engineering group has breadth and depth of experience and expertise in the delivery of chassis systems, across products ranging from passenger cars and sports utility vehicles through to commercial vehicles as goods or people carriers.

This covers all aspects of the engineering task from concept to production solutions for the different chassis systems:

  • Frames, Suspensions & Axles
  • Steering, Wheels & Tyres
  • Foundation Braking & Electronic Stability Control
  • Regenerative Braking & Advanced chassis electronic control systems
  • Active safety and collision avoidance systems

The team can lead or support the design and development process as applicable and takes an integrated analysis-based approach to optimise the performance, through the design, development and certification phases of a project.
