DETROIT — GKN Driveline is launching its constant velocity joint driveshaft technology, called Countertrack, this year.
The European Volkswagen Passat is the first vehicle with the technology. Production started this year, and GKN expects to make 3 million units of Countertrack in 2010.
The technology uses sets of opposed ball tracks with a new track shape profile to improve driveline efficiency. It improves fuel economy by an average of 0.2 mpg on a front-wheel-drive mid-sized vehicle, GKN said in a statement.
GKM Driveline is part of British supplier GKN Automotive, which makes sideshafts, propshafts, torque management systems and geared components.
