The 2000 Dodge ESX3 Concept, introduced by James Holden, President of DaimlerChrysler AG, aimed to offer a mass-market vehicle with space-age technology at affordable prices. Externally, the ESX3 presented itself as a middle-class five-seater family sedan. The power plant featured a lightweight 1.5-liter 3-cylinder diesel engine with direct injection from Detroit Diesel, assisted by a 15 kW electric motor from Delphi driving the front wheels. The electric motor operated as needed, powered by a rechargeable battery that recharged during braking, promoting fuel efficiency.
The lithium rechargeable battery, provided by the French company SAFT, weighed only 48 kg and was strategically placed between the rear wheel arches without compromising trunk volume. The concept boasted an electromechanical (EMAT) 6-speed transmission with two "sequential" clutches, combining the convenience of an automatic with the efficiency of a conventional manual transmission. To achieve weight reduction, the ESX3 utilized a load-bearing plastic body consisting of only 12 parts, integrated with reinforcing elements made of aluminum. This design resulted in a body that was 46% lighter, 15% cheaper to manufacture, and more rigid compared to traditional steel bodies. The plastic body parts were durable, paintable, and 80% recyclable, showcasing the corporation's commitment to innovative and sustainable automotive technology.
