American Axle & Manufacturing is making SUVs and crossovers significantly more efficient with its EcoTrac disconnecting all-wheel-drive system, says David Crecelius, director of product engineering-electrification.

EcoTrac reduces system drag as much as 90% compared with simple mechanical awd systems, thanks to sensors and proprietary software used to monitor and analyze road conditions. The system decouples rotating driveline components when they’re not needed.

AAM also has debuted its first electric drive system in the Jaguar i-Pace electric SUV. The technology features an exceptionally power-dense design with separate, 150-kW drive units on the front and rear axles, Crecelius adds.
