| Hyundai Thomas Gehrlich, head of vehicle development, Hyundai Motor Europe Technical Center "A Hyundai should be easy to drive with a balance of dynamic handling and ride comfort. The balance changes to suit individual vehicle segments and different regional market requirements. It’s important to give the driver clear road feedback and very precise steering is a must for creating a fun-to-drive experience.
"Hyundai’s ride and handling is improving, especially in the large vehicle segment, by using high tensile steel in critical areas of the body and refining the suspension design and tuning. "Improved fuel economy will mean smaller, more aerodynamic vehicles with a lower ride height and lower rolling resistance tyres – all affect ride and handling and will require development efforts. It will also drive weight reduction, which is advantageous for dynamics, but the challenge will be keeping the stiffness and vibration to an acceptable level. "A- and B-segment cars will retain conventional suspension designs. Customers get very good value with even the most basic setups, but there is great potential for further refinement and improvements. "The higher segments will get more active systems. Integrating conventional suspensions with electronic control systems will improve fuel efficiency, safety, comfort, body/wheel control and will also optimise road surface contact. "Intelligent steering support for the driver combined with other systems have great potential too. But we believe the systems should remain in the background in a supporting role for the driver. "Electric-power assisted steering will come to our D-segment vehicles in the next few years and its application will expand from there to other segments. The main consideration is balancing fuel efficiency with demand for ride and handling comfort. "Torque vectoring could also help improve handling and will appear first on high powered/performance oriented vehicles, but we see it the systems should remain in the background in a supporting role expanding to different types of vehicles."
