“Andrew Keefe was the reason that our engineering team was able to successfully complete the delivery of a fully-functional class-8 hybrid diesel/electric truck within the eight-month timeframe promised. It was due to his insight that called for the development of a system that could capture the regeneration energy from a vehicle moving downhill and recover that energy on uphill segments that allowed the efficient and effective use of the onboard energy storage system. His leadership on this project propelled the entire team to achieve this goal.”
