TheHonda JNC1 engine is a bespoke 3.5-liter,twin-turbochargedV6 engine, designed and produced byHonda for the second generationHonda NSX (NC1).[1][2][3][4]
The JNC1 engine is built inHonda's Anna Engine Plant inAnna, 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 of the rear tires, lowering thecenter of gravity.Cosworthsandcasted the block and cylinder heads, while the pistons arecast aluminium.[6]
The engine is mated to a 9-speeddual clutch transmission in the rear.[7] There are threeelectric 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 featurestorque vectoring on the front wheels, creating ayaw 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]
