NSF and DOE form Partnership on Advanced Combustion Engines; goal 25-40% better LDV fuel economy and 55% BTE in heavy-duty engines; $12M in awards for FY 2012-2014

Green Car Congress

The high-level performance goals of the Partnership are a 25-40% improvement in fuel economy in a light-duty vehicle (LDV) and achieving 55% brake thermal efficiency (BTE) in heavy-duty engine systems. Liquid fuels have dominated transportation systems for over a century and will continue to do so for decades to come.
