John Kimes, CEO & President
CEO & President
John has spent his professional career developing new transmission technologies. While attending General Motors Institute (now Kettering University), he co-oped at General Motors from 1989-1994. Upon graduation, John worked at GM Powertrain (formerly Hydra-matic at Willow Run) until 2000 where he was the lead development engineer of the 4L80e and lead developer of the 4L65e.
John then worked at The Ford Motor Company from 2000-2007 as a technical specialist in mechanical clutches and invented the rocker one-way clutch, which won the 2004 Technical Excellence Award. After Ford he contracted with Means Industries where he invented, designed, and built the all-electric Sync Shift Transmission. Ford still currently produces subsystems that were developed by John. Other OEMs are evaluating additional transmission designs and subsystems from John for production soon.
John is the inventor of 45 U.S. patents for transmission technology and currently has numerous others in process. His latest creation is the EMAX modular commercial duty electric powertrain which uses an innovative electro-mechanical system for mechanical clutches.
Phil Woodley, Design Manager
Phil Woodley is a highly regarded mechanical engineer known for the quality of his work, his attention to detail, and resourcefulness. Phil’s extensive work experience in plug-in hybrid and battery electric vehicle technologies has included leading engineering teams for the past 10 years.
While Phil is a mechanical engineer by trade he is also highly knowledgeable about electro-mechanical and power electronic devices, and is experienced with all types of vehicular powertrains.
David Sutherland, Operations Manager
David was the engineering program manager for a $1.3 billon/year diesel powertrain program. His responsibilities included supervising production release, quality control, warranty service, parts, and change control. This program spanned five platforms at four assembly plants and a manufacturing plant. Under David, the program saved over $30 million in costs while reducing warranty costs by 16%.
For the past two years, David has been operational manager for Sigma Powertrain, and has been the lead employee for infrastructure and manufacturing. He has delivered fully-operational, innovative power flow systems for conventional and all-electric applications.
Scott Russell, Lead Controls/Software Manager
Lead Controls/Software Manager
Scott graduated from General Motors Institute (now Kettering University) while co-oping at Detroit Diesel Allison (now Allison Transmission) with a B.S.M.E., then attended Stanford on a GM fellowship to get his M.S.M.E. During his twenty years at GM/Delphi, he also picked up an M.S.E.E. at Marquette University.
While at GM/Delphi, he worked on transmissions, engines, engine controllers, aerospace navigation systems including gyroscopes, ABS, and electric power steering. In 2000, he moved to Continental-Teves (now Continental Automotive) where he worked on various features of electronic brake systems including a stint as the supervisor of a customer application group and integrated park brake. His responsibilities included design, development and calibration.
Scott has long been part of Sigma Powertrain and its predecessor companies as the control engineer and he has used his combined mechanical and controls expertise as a general system debugger since the original two-speed ZAP project.
Dan Knieper, Software Architect
Dan graduated from Michigan Tech with a bachelor’s degree in Electrical Engineering.
