LAKE FOREST, Ill. (Feb. 24)—Tenneco Automotive Inc. has designed a lightweight elastomeric rear suspension system it claims will allow car makers to eliminate traditional springs and associated mounts and brackets. The patented Elastomeric Torsional Axle—a simple axle tube with elastomeric spring elements—reduces the complexity of rear axle design by up to 40 percent, making it optimal for use in minivans and passenger cars, Tenneco claims. The design is being used by DaimlerChrysler A.G., Ford Motor Co. and General Motors Corp. on their respective high-mileage concept cars.
