Cummins Westport Captures New Market Opportunity in Lima, Peru With Order for Over 200 Natural Gas Bus Engines

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 11, 2008) - Cummins Westport Inc. (CWI) (TSX:WPT)(NASDAQ:WPRT), a leading provider of high-performance, alternative fuel engines for the global market, announced today that it has received an order for over 200 CWI natural gas engines to equip new buses for transit providers in the capital city of Lima, Peru.

"Peru's growing market for natural gas vehicles and substantial indigenous supply of natural gas represents an exciting new market opportunity for our clean burning, low emission engines," said Guan Saw, CWI's President.

According to the International Association for Natural Gas Vehicles and its publication NGV Global, Peru has the fifth largest proven natural gas reserves in South America and over 7,800 natural gas vehicles as of mid-2007. Natural gas vehicles are not new to South American markets. Argentina and Brazil, for example, have significant natural gas reserves and production, existing fuelling infrastructure, and some of the highest natural gas vehicle populations in the world.
