Clean Diesel Technologies (CDTI) Announces Honda Win

VENTURA, Calif., July 30, 2012 /PRNewswire/ — Clean Diesel Technologies, Inc. (NASDAQ:CDTI) (“Clean Diesel” or the “Company”), a cleantech emissions control company, is pleased to announce that it has begun supplying catalysts for next-generation four- and six-cylinder Honda Accord models. The Company expects to announce additional model programs in 2013 as it continues close collaboration with Honda on other high-performance six-cylinder and hybrid vehicle applications.

Clean Diesel’s latest catalyst offerings to Honda leverage its proprietary breakthrough MPC^© technology and include a high-performance catalyst which is designed to meet stringent California Air Resources Board (“CARB”) Super Ultra Low Emissions Vehicle (“SULEV”) emission standards. Clean Diesel will also supply a palladium-only (“Pd-only”) catalyst that significantly reduces precious metal content when compared to competitive products that typically include more expensive and price volatile metals such as Platinum and Rhodium.

“We are proud to be Honda’s catalyst supplier for the Accord — one of the best selling cars in North America — and we look forward to our catalysts being introduced on other new and exciting Honda vehicle models. Honda’s confidence in our ability to consistently provide superior catalyst solutions is a clear indicator of our technology leadership. We believe that these latest product introductions highlight our strategy to grow sustainable OEM business through technological innovation which expands our footprint with existing customers and creates opportunities to selectively add new customers,” said R. Craig Breese, Clean Diesel’s President and Chief Executive Officer.

Clean Diesel’s Catalyst Division began delivering catalysts to Honda in 2001 – offering a unique combination of high performance and low precious group metal content, resulting in significant economic benefits. Since then, Clean Diesel’s catalysts have been sourced for new model programs that typically span four to five years, including the popular model years 2004 and 2008 Accord.
