Through development collaboration with German steering specialist ZF Lenksysteme, the ATS’ electronic power-steering system has been revised with new software programming that promises to improve feedback at high speeds without sacrificing drivability in parking lots.
The system considers wheel speeds, steering angle and the car’s chassis mode to determine the optimum steering assist throughout a broader range of driving scenarios.
ZF Lenksysteme’s Kevin Woodward claims his company’s steering gear already provides a high level of torsional stiffness and low operating friction for an “almost perfect” linear response, while minimizing fuel consumption compared to conventional hydraulic systems.
GM has focused on handling in its quest to make the ATS a viable competitor against its German rivals. Both the coupe and sedan are relatively lightweight for the segment, while optional magnetic dampers help reduce body roll during spirited driving.
The 2015 ATS models are expected to arrive on the market later this summer.
