American Axle & Manufacturing Holdings, Inc. (“AAM”), announced launch of its new EcoTrac brand of fuel-efficient and environment-friendly driveline products. The EcoTrac brand includes an all-wheel-drive (AWD) fuel economy optimization system, e-AWD systems and a full range of high-efficiency axles.
EcoTrac AWD System
AAM’s EcoTrac all-wheel-drive system enables a vehicle manufacturer to offer a passenger car or crossover vehicle with an all-wheel-drive option that minimizes the impact to fuel economy and reduces emissions when compared to a front-wheel-drive vehicle.
The EcoTrac system allows the AWD vehicle to utilize its primary drive system, the front wheels, when AWD is not required. Vehicles equipped with this advanced fuel economy optimization system can automatically transition to AWD, seamlessly and without disturbance to the driver, when the vehicle senses that AWD may be necessary. Utilizing an AAM-designed electronic controlled coupling (ECC) in the rear drive module, the system is activated and gently brings the driveline to a proper speed, delivering the necessary torque and vehicle stability performance. When conditions allow, the vehicle reverts back to an economical mode, conserving fuel and reducing emissions. The proprietary AAM electronic control software and hardware eliminates driveline mechanical losses which aid in maximizing fuel efficiency while providing enhanced vehicle control and fully variable AWD performance.
e-AWD Systems
AAM’s newest Joint Venture e-AAM Driveline Systems AB will launch electric all-wheel-drive (e-AWD) systems that are designed to improve fuel efficiency up to 30 per cent, reduce CO2 emissions and provide all-wheel-drive capability with the further benefit of torque vectoring for vehicle stability when compared to traditional mechanical AWD mechanical systems. This e-AWD solution is ideal for a range of passenger car and crossover vehicle configurations including conventional internal combustion engines, battery-powered hybrid platforms, plug-in platforms, or full electric drive systems.
EcoTrac High-Efficiency Axles
AAM’s EcoTrac high-efficiency axle systems demonstrate world-class axle efficiency by implementing proprietary technologies to optimize the product design and lubrication efficiency while also reducing friction. Efficiency features being implemented in the product line-up include new PowerDensehypoid designs, gear finishes, high-efficiency bearings and proprietary lubricants.
A key feature of these high-efficiency axles is PowerFilm, a proprietary lubricant that provides reduced friction under high torques while also reducing energy losses within the axle. The combination of this technology within AAM’s EcoTrac high-efficiency axles can reduce axle-related energy losses by up to 50 per cent for OEM vehicles.
“We are excited to be launching AAM’s new EcoTrac brand of fuel-efficient and environment-friendly driveline products, AAM’s powerful response to our customers’ need for better fuel efficiency, lower CO2 emissions along with superior ride and handling performance,” said AAM President and Chief Operating Officer David C. Dauch. “The introduction of the EcoTrac AWD system strengthens AAM’s position as a leader in providing industry-first, cutting edge driveline technology for global passenger car, crossover vehicle and light truck applications.”
“EcoTrac’s state-of-the-art product features offer vehicle manufacturers many innovative solutions for improved fuel economy and reduced emissions. Global customer response has been strong,” said Mark Barrett, AAM Vice President for Engineering and Product Development. “EcoTrac enhances AAM’s technology leadership position and allows us to continue expanding and diversifying AAM’s product portfolio and customer base.”
