Overview

The JNC1 engine is built in Honda's Anna Engine Plant in Anna, Ohio and takes around five hours to complete. [5] The 75° cylinder angle gives the engine its unique design so that the engine stays below the level if the rear tires, lowering the center of gravity. Cosworth sandcasted the block and cylinder heads, while the pistons are cast aluminium. [6]

The engine is mated to a 9-speed dual clutch transmission in the rear. [7] There are three electric motors, two in the front and one in the rear. The Twin Motor Unit (TMU) is mounted on the front wheels providing 36 hp (36 PS; 27 kW) while the rear motor produces 47 hp (48 PS; 35 kW). [8] The TMU features torque vectoring on the front wheels, creating a yaw moment during cornering by sending more torque to the outside wheel and less negative torque to the inside wheel. When exiting a corner, positive torque is applied for faster acceleration. [8]
