WABCO’s air system solutions are engineered for optimized performance with less energy consumption


Today’s North American fleets are continuously searching for fuel economy and improved profitability without sacrificing performance, especially as fuel prices continue to increase. Many solutions introduce new challenges. In the 6x2 versus 6x4 discussion, these challenges become opportunities for efficiency and profit.

At WABCO we help in this discussion with Electronically Controlled Air Suspension (ECAS), a key part of our Efficient Air Solutions portfolio. The WABCO ECAS is designed to enhance the traction performance of 6x2 axle configurations and provide ride height flexibility by managing the vehicle’s air suspension. ECAS also provides Automatic Level Control, continually monitoring the vehicle’s height (axle-to-frame distances) and correcting deviations quickly when needed through exhausting or pressurizing the air suspension bags. ECAS will maintain the nominal vehicle level regardless of the freight load or number of passengers loading or unloading.
