Buehler Motor, Inc. to Provide Auxiliary Water Pumps for Chevrolet Volt and Some GM Hybrid Vehicles Technology Partnership and Contract Signal Automotive Industry’s Continued Confidence in Buehler Motor’s Customized Drive and Pump Solutions DETROIT, Oct.

20 /PRNewswire/ — Convergence 2008 - Booth #119 — Buehler Motor, Inc., a leading international provider of mechatronic drive and pump solutions with a specialty in the automotive industry, has announced it has finalized contracts with General Motors to provide customized auxiliary water pumps for the Chevrolet Volt Extended-Range Electric Vehicle and some GM hybrid vehicles.

The Chevrolet Volt being developed by General Motors delivers up to 40 miles of gasoline- and emissions-free electric driving, with the extended-range capability of hundreds of additional miles. Drawing upon GM’s experience inaugurating the modern electric vehicle market with the launch of the EV1 in 1996, the Volt uses a gas engine generator to create additional electricity to extend its range hundreds of miles until the vehicle can be plugged in and battery-charged.

The much-anticipated production version of the Volt was unveiled last month, with production expected to begin in late 2010. Under terms of the contracts, Buehler Motor will provide custom 12W and 50W auxiliary water pumps for the Volt and GM hybrid vehicles. Other details were not released. The two companies have been working together in a technology partnership since mid-2007 to customize the water pump technology necessary to circulate coolant through the Volt’s subsystems.
