Premium electric power steering refines 2015 ATS Coupe ride without sacrificing handling
DETROIT – Cadillac and ZF Lenksysteme GmbH, a leading supplier of automotive steering systems, have teamed to create world-class dynamic handling and steering for all models of the 2015 ATS.
Starting with the excellent mechanical steering system, the electronic power assist steering gives a wider range of assist, resulting in an incredibly communicative, well-weighted and responsive steering experience, said Kevin Woodward, global key account at ZF Lenksysteme.
For 2015 ATS models, including the all-new ATS Coupe, the feel of the electronic power-assisted steering has been improved through revised programming within the electronic control unit. New programming broadens the range of steering assist at low and high vehicle speeds, based on wheel speed, steering angle and even the car’s chassis mode.
“It means that you don’t have to sacrifice parking lot feel for spirited driving feel,” Woodward said. “The new software change illustrates our ability to balance the goal of spirited performance, nimble and quick-responding steering with the premium luxury feel expected by Cadillac owners.”
The electric, variable-assist power steering system from ZF Lenksysteme is designed to deliver excellent response and on-center characteristics while saving fuel since engine power isn’t directly required to assist gear movement – as is the case with conventional hydraulic systems.
“Premium electric power steering by ZF Lenksysteme steering gear has great torsional stiffness and low operating friction to enhance the steering feel with almost perfect linear response,” Woodward said. Additionally, the steering column and intermediate shaft feature stiff, direct-acting and low-friction ball bearing designs for a more immediate, connected-to-the-road feel for the driver.
