Development of this driveline involving new traction control systems and rear wheel steering continues. Linamar has two divisions, Powertrain/Driveline and Industrial. Nexteer is a global manufacturer of steering and driveline products. Most 504 models used a torque tube driveline. Most rat rods are rear-wheel drive, with an open driveline. Other quotable new features is the I-torque driveline and the I-see fuel saving technology. The engine was repositioned to improve driveline angle and weight distribution. Active Driveline became initially available on Si4 petrol engine. These are particularly prone to driveline windup. A drawback to the H-drive is the risk of driveline windup. Dynaflow's non-shifting design addressed this characteristic of Buick's driveline. Directly adjacent is also a factory of the supplier GKN Driveline. The CPC-KERS is similar as it also forms part of the driveline assembly. In October 2010, Rheinmetall MAN Military Vehicles agreed to cooperate with driveline specialist Timoney Technology. Boddy continues to remain affiliated with Driveline.
