The second series in the ESX line completed testing in 1998 and made several improvements on its predecessor. The ESX2 was dubbed a "mybrid" (mild hybrid) because its reliance on electrical power was not highly dependent on the battery. This system contained two motors that worked in parallel: a 1.5 L 74 bhp direct-injection diesel and a 20 bhp AC-induction electric motor. The main power came from the diesel engine. The electric motor charged the batteries, added to the acceleration, and powered the reverse gear. Coupled with the powertrains were a 5-speed electronically shifted manual transmission, a nickel-metal hydride battery pack, and controlling equipment which included components from the Patriot hybrid race-car program.
Chrysler fit the car with an unpainted thermoplastic body attached to an aluminum frame to cut down on cost and weight. The shape had a low aerodynamic drag. Inside, trim was constructed of carbon fiber, and the seats were built from a tube frame—the final cost: only $15,000 more than a regular Intrepid, or about $37,000.
