Thomas Engine Company (TEC) is an internal combustion engine design and licensing company. Our mission is to continuously improve the fuel economy and emissions of engines without compromising power and without increasing product cost.

Our flagship technology is a game-changing variable compression ratio engine platform, on which the designs of our two first engines, the gasoline-fueled TEC-1™ and JP-8 diesel-fueled TEC Helios™ are based.

TEC is actively seeking development partners and licensees.
