WABCO to supply vacuum pump technology for GM passenger cars

ABR Staff Writer Published 09 September 2011

WABCO Holdings has entered into a multi-year agreement with General Motors to supply mechanical vacuum pump technology for gasoline direct-injection (GDI) engines in passenger cars to be produced in North America, Europe and Asia.

The series production of engines is expected to commence in 2012 and the company's vacuum pump technology offers a light-weight design with ultra-low power consumption attributes.

The company said that the vacuum pumps are a critical component of the vehicle's braking system in passenger cars equipped with diesel and GDI engines, and in some applications, vacuum pumps also deliver non-braking functions such as actuation for variable-geometry turbochargers.

WABCO's patented vacuum pump designs allow these secondary functions to be delivered in isolation from the primary braking function, thus ensuring no interruption to the critical brake-support function.

WABCO vice president of car systems Mike Thompson said the company's vacuum pump technology helps car makers to improve fuel economy and enhance driver satisfaction while producing cleaner, environmentally friendly vehicles.

"We are passionate about continuing to raise the industry standard for automotive engine-driven vacuum pumps while meeting the growing global demand for vacuum pumps that offer high performance and ultra-low power consumption," Thompson said.
